Key takeaways

  • Successful AI tools are specific: Instead of relying on generic tools, it is most effective to use software like AI proposal writing tools that are tailored to your industry’s specific needs and considerations.
  • AEC marketing has unique needs: Compliance errors, RFP complexity, and tight deadlines make AEC proposals different from any other industry. You need tools that reflect that.
  • How AI proposal writing tools support you: Most AI proposal writing tools share some common features: database organization, automatic information generation, and compliance tracking.

Work in AEC marketing long enough, and you probably notice this familiar rhythm. Peak proposal season hits, deadlines start stacking up, this year’s crop of RFPs is more complex and demanding than ever, and you end up stuck spending hours you don’t have trying to find the right project narrative to truly sell the next proposal sitting on your desk.

Meanwhile, the perfect one is sitting hidden away in a folder nobody’s touched in two years, right under your nose.

AEC marketers are some of the most resourceful professionals in the industry. They have to be. But resourcefulness has its limits, and that’s where AI proposal writing tools can support you.

What is AI-assisted/AI-powered proposal writing?

AI-assisted proposal writing is exactly what it sounds like: AI that helps you write — faster, smarter, and with less starting-from-scratch frustration. But the most important word in that description is “assisted.” You cannot make AI write a proposal for you, but marketers can use AI to support them in a dozen useful ways.

Think of it as a knowledgeable colleague who’s read every proposal your firm has ever written. They know your voice, your past projects, and your winning themes. When a new RFP lands, they don’t hand you a blank page. They hand you a strong starting point.

Here’s how it works in practice: You upload an RFP. The AI reads it, extracts what matters, and surfaces relevant content from your proposal library. It looks at past project narratives, team bios, and compliance language your firm has already vetted. You can then take that material, shape it, and make it yours.

The AI doesn’t replace your judgment. It removes the busywork so your judgment has room to breathe.

Why use AI in your proposal writing?

The basic pitch is that AI can make writing faster and easier. Critically, however, it is not able to write the entire proposal for you. AI can do a lot of extremely effective grunt work, but it cannot replace a thinking professional’s experience and decision-making.

This matters because the hardest part of proposal writing isn’t the writing itself. It’s the hunt. Digging through shared drives. Tracking down the right resume. Finding that project narrative you know exists somewhere. AI-assisted writing solves this, so your team can spend less time searching and more time crafting the story that wins the work.

For AEC marketers juggling tight deadlines and complex RFPs, AI-assisted writing isn’t a luxury. It’s how you stay competitive without burning out your team.

Who uses/benefits from AI proposal writing tools?

AI writing assistants can benefit anyone, but proposal writers and AEC marketers both especially benefit from AI proposal writing tools. Compared to generic AI tools like ChatGPT, AI proposal writers are designed specifically to write proposals. AI proposal writing tools work under a different set of priorities and sensibilities than generic AI tools. This is what makes them the most useful tool for AEC marketers, as they are more attuned to the industry’s specific needs.

What are the best proposal writing software/tools?

The best AI tools are specific.

In 2025, an MIT report found that 95% of enterprise-scale AI pilots were failing to reach full implementation. That’s a pretty grim number, but it gets more interesting when you look at the 5% that succeeded. 95% of the failures were in-house productions using simple, generalist software that can plug into any business regardless of industry. That little AI chatbot that shows up in the bottom right corner of nearly every website you visit these days? Most companies aren’t getting much out of it. But this just means that you have to use AI the right way, because it gets really interesting once you look at the companies that are succeeding.

When do AI technologies work?

There are two defining qualities that set apart the companies that are getting an ROI from AI tools.

  1. They reach out to specialized vendors instead of trying to figure out how to apply the technology themselves. Not just companies that specialize in developing AI tools, but AI tools for their specific field.
  2. They approach AI the same way one should approach any software: With a specific pain point they want to address.

Instead of just using AI because it is the current reigning buzzword, successful companies start with the problem, inefficiency, or bottleneck they are struggling with. Then they ask: What can solve this?

Often, that answer can be AI. And when it is, it is usually a tool built specifically to deal with that pain point or a custom-made tool commissioned to handle that exact problem.

In that sense, AI tools are no different than any other technology. They are most successful when they are used with intention.

The best AI tools for proposal writing

The lesson here is pretty clear: To get real value out of AI, you want to use technology built specifically for your industry. You want to look for technology that directly answers problems your marketing team is experiencing today and can demonstrate how it will improve your production pipeline.

These are some of the most popular AI tools for proposal writers:

  • Shred.ai: Purpose-built for AEC, Shred.ai is fine-tuned by real AEC marketers with 20+ years of experience, powered by Anthropic’s Claude, and built with SOC 2 Type II compliance and strict data isolation. Its core differentiator is its native integration with OpenAsset’s DAM, meaning project photos, team bios, and firm data flow directly into the proposal process. Key features include RFP “shredding” for compliance extraction, AI Chat using retrieval-augmented generation (RAG) sourced from your proposal library, go/no-go scoring, and semantic search.
  • Jasper AI: Jasper is a content-focused AI platform designed for marketing teams. It can help generate structured drafts, maintain brand voice, and scale content production. While not specific to AEC, it’s useful for firms looking to standardize messaging across proposals and marketing materials.
  • GrammarlyGO: GrammarlyGO extends beyond grammar checking into AI-assisted writing and tone refinement. For proposal teams, it’s useful in polishing final drafts, ensuring clarity, and maintaining a consistent voice across contributors. It’s best suited for editing and refinement rather than full proposal generation.
  • Notion AI: This tool combines workspace organization with content generation, making it useful for teams managing proposal drafts, boilerplate, and collaboration in one place. It can help generate and refine content while keeping everything centralized, though it isn’t purpose-built for AEC proposal workflows.

Features of AI proposal writing software/tools

The common feature shared by all AI proposal writing software is that they save time. Different tools do this in different ways, but you may have noticed a few features that pop up time and again across all of these tools:

  • Database organization: These tools organize a chaotic, disjointed database. This makes it possible to find old content that would sit forgotten in the corner of a random computer’s drive and help maintain institutional knowledge that would be lost if key employees move on to another company.
  • Automatic generation: From basic information to employee bios, some parts of a proposal are the same every time. These parts don’t require any thought — just a lot of labor and copying and pasting. For these tasks, AI is an able helper.
  • Go/no-go decision support: While they are already organizing all of your information into a single database, these tools are well-situated to provide you with go/no-go support. By understanding your company’s entire history, they can give you the insights you need to make informed go/no-go decisions.
  • Compliance guardrails: Most of these tools include some form of automated compliance tracking, comparing your work against the list of requirements in an RFP. They act as a “second opinion,” giving you one more safeguard against a fatal compliance error.
  • Integrations: Software of all stripes live and die on their integrations, and you are far more likely to find software that integrates with the rest of your tools by looking at related specialists that work in the same industry.
  • Understanding RFP response language: Because they are designed with the AEC industry in mind, these tools can read industry-specific documents like RFPs more accurately than generic tools that treat them like any other document.
  • AI chat: One advantage AI has over other types of software is the ability to explain itself. If you don’t understand why the program is giving you a specific output, you can just ask it why. And the AI can give you a real, nuanced answer instead of just spitting out an error code you have to spend 30 minutes googling.

In each case, AI proposal writing software returns to this same value proposition: saving you time for the big picture work.

An in-depth example with Shred.ai

Let’s bring everything we just learned together by drilling down into one example with Shred.ai. How does this all look in action?

Shred.ai checks all the same boxes that other, more generic AI tools do. It organizes your database into a “living library,” making it faster and easier to find existing content, then repurpose it for new projects. Shred.ai can generate boilerplate copy and handle repetitive busywork so you don’t have to. It tracks compliance requirements and double-checks to make sure your proposal follows them.

So how does Shred.ai stand apart? Remember the two rules of successful AI tools: they are produced by companies that specialize in that field, and they get specific in the pain points they are targeting.

Rule 1: Working with a specialized vendor

OpenAsset is not just a company designing tools specifically for the AEC industry. It is a company with decades of expertise in designing digital asset management (DAM) systems specifically. This gives you a leg up when you use Shred.ai.

DAM integration

One of Shred.ai’s standout features is its integration with the rest of OpenAsset’s DAM tools. This feature is incredibly useful for an AI proposal writing tool that primarily helps you by analyzing your internal database, but Shred.ai is the only software of its kind that has it.

This integration lowers the barrier between you and the perfect assets for your project even further, as Shred.ai draws on the work that the DAM software has already done organizing your data. This leads to faster asset retrieval and more consistent branding across every project.

Responsible, focused training

Many AI tools and LLMs take as much as they give. The entire time ChatGPT is helping you craft a paragraph you’re having trouble with, they’re also using your own information to train their models to spit back out to someone else.

This can be less than desirable when working with sensitive documents. You don’t really want those just floating around some LLM’s database unsecured. It can also be quite personal: Most people don’t like the idea of their hard work being co-opted for free by an AI to be regurgitated across the internet.

There’s also the reverse issue: everybody else’s information is getting mixed up with yours. You wouldn’t write a proposal the same way a motor manufacturer would list out the features of their newest product or a wine blogger would wax on about the flavor notes of their favorite pinot grigio, but generalist tools are drawing on all of these different fields for guidance on style, tone, and a dozen other aspects of writing.

OpenAsset understands that these privacy problems aren’t acceptable in the AEC industry. Shred.ai does not train itself on your data. Instead, it is trained by OpenAsset’s internal marketing team on their data. It is also SOC 2 Type II compliant, ensuring that your information will be protected.

Internal training also means that the AI is trained to help write proposals specifically. It understands the common taxonomy and other unspoken norms that are standard across the AEC industry.

All of this is possible because of OpenAsset’s existing expertise. After working in the industry for over 20 years, we understand what you need to do your job best.

Rule 2: Target specific pain points

Many of OpenAsset’s products are designed to target the same pain point: disorganization.

Every company experiences this challenge. The marketing department can be working with a completely different set of assets from the sales team, and if both of those teams are just working off a computer’s hard drive, neither will ever be able to use the other’s materials.

Even if a company has centralized all their materials on the Cloud, time will inevitably take its toll. Perfectly good assets will be lost over the years, forgotten in a random folder after the two people who used them moved on to another company.

This is particularly difficult when it comes to AEC marketing teams, most of which are smaller than a dozen strong. When you’re fighting just to keep up with the churn of proposals your company wants to hit, “nice to haves” like a clean, well-archived, and organized database tend to fall to the wayside.

Shred.ai, like all of OpenAsset’s products, is designed to handle this task for you. Many of its basic features accomplish this goal, but it also goes above and beyond in a few ways.

AI chat assistance

Shred.ai’s AI chat feature helps resolve another potential pain point. Namely, that technology can be complicated and often requires someone to engage with it on its level. With some software, you have to learn how to speak its language before you can use it.

Shred.ai’s chat is an opportunity to flip that equation around. Instead, it speaks in your language and can talk about its findings in a conversational and helpful manner.

This allows the software to explain itself in more subjective ways than a hard data search can, discussing softer topics like themes and strategy. It also gives your team a faster, on-demand method to pull examples or summarize content.

Go/no-go analysis

One of the benefits of centralizing all your data into a single library is the opportunity to use all that info for analytics purposes. It’s a perfect opportunity to tackle another AEC-specific concern: go/no-go analyses. 

Often, go/no-go analysis is based on experience. What is a good fit is often decided by where the company has succeeded before. In order to know that, you need a comprehensive history of your successes all laid out in one place.

Shred.ai, as well as many other proposal writing tools, is already designed to build and analyze that comprehensive history. In doing so, it is perfectly positioned to offer guidance on that history with a speed and accuracy that can only be matched by an employee who lived the entirety of it.

This sort of expertise is invaluable in the AEC industry, but this isn’t even on a lot of generalist AI’s radars. Being designed for the AEC industry, Shred.ai would not be complete without supporting this vital part of any marketing team’s daily work.

Putting it all together: compliance criteria

All of this comes together when we look at how different tools handle compliance criteria. This is a fantastic example of what separates a specialist from a generalist tool.

Pretty much any AI tool from ChatGPT to Shred.ai can read and summarize text. But anyone who has worked in the AEC industry knows that when working with legal terms and compliance rules, exact wording is important.

RFP compliance is also an AEC-specific pain point, unique both in its requirements and its consequences. Compliance errors spoil dozens of hours of work and can single-handedly sink an otherwise fantastic proposal. AEC marketers have to worry about this in a way that other marketing fields simply don’t.

A generalist tool can work for summarizing long emails and marathon team meetings, but it may try to treat that RFP like any other document and miss something vital. In these cases, an executive summary isn’t good enough.

Instead, Shred.ai will always give the criteria to you verbatim, so you can know with absolute certainty exactly what the rules are. It gets specific where more generalist tools can be vague. It knows what you need to make an effective proposal, and it knows best how to help.

That is the value of a specialist in a nutshell.

FAQs about AI proposal writing tools

Still want to know more about how AI proposal writing tools work? Here are some frequently asked questions about AI tools:

What is an AI proposal writing tool?

AI proposal writing tools are support software that help lighten the load on projects, letting you focus on the most critical aspects of each project. AI tools are perfect for handling repetitive or administrative tasks that would normally occupy hours of your time every week, freeing you up to focus on the more complicated or subjective parts of a proposal.

How does AI help with proposal writing?

AI proposal writing tools organize your content library, surface relevant past proposals, extract RFP compliance requirements, and generate first drafts. This frees your team to focus on the strategic, creative work that actually differentiates your firm.

Can AI write an entire proposal for you?

No, AI cannot write an entire proposal for you. AI is incredibly helpful in several ways. It can research your old work and find useful content for your current project, help fill in the basic everyday details that are the same in every proposal, and double-check to make sure your proposal is compliant. What AI cannot do is make big decisions. A trained professional who has spent years honing their craft will make better creative decisions, craft more convincing arguments, and write in a more fluid and human tone.

It is best to think of your AI as an eager but inexperienced intern. It is capable of a great amount of grunt work, but it does not have the expertise to make smart decisions on more subjective topics like overall proposal strategy the same way you can.

What’s the difference between ChatGPT and proposal-specific AI tools?

ChatGPT is a generalist tool. It can write about almost anything, but generalist tools have no knowledge of your firm, your past projects, or the specific demands of AEC proposals. Proposal-specific tools are trained on industry content, connected to your internal library, and built to understand the compliance requirements and workflows unique to your field. The difference shows up most clearly when precision matters — and in AEC proposals, it always does.

What features should AI proposal writing tools have?

An AI proposal writing tool should have semantic search, AI chat, compliance tracking, and a centralized proposal library that grows smarter with every upload. AEC-specific tools should also offer go/no-go decision support and integrate with the platforms your team already uses, like your DAM system or CRM. The best tools don’t just save time. They actively reduce compliance risk and help your firm build on its own institutional knowledge.

Can AI tools help with RFP compliance tracking?

Almost all AI proposal writing tools come with some form of compliance tracking assistance. Many AI tools will automatically analyze an RFP for any compliance requirements, then pull them from the document in an easy-to-read list. Some tools also double-check your work and make sure that the finished proposal meets that list of requirements.

However, how each tool does so might differ. Some might just give you an executive summary that leaves out important details. The best will give you the compliance requirements verbatim.

How do AI tools support go/no-go decisions?

AI tools have an unmatched ability to study the entire history of your company, look at which proposals won and which did not, and find common connections. This provides a data-rich foundation for making go/no-go decisions.

With that foundation, the AI tool can offer recommendations on which future proposals are squarely within your company’s expertise. Having all that data on hand means that you, too, can study potential projects with a critical eye, looking for similarities to past proposals you’ve knocked out of the park.

Work faster and smarter with AEC-specific support tools like Shred.ai

The takeaway from all of this is simple: the right AI tool makes your team better at what they already do well.

For AEC marketers, that means fewer hours lost to searching, copy-pasting, and compliance double-checking, and more time spent on the creative, strategic work that actually wins projects.

But “the right tool” is the key phrase. Generic AI can do a lot of things adequately. It can’t do what a purpose-built, AEC-specific platform can. It doesn’t know your industry, your workflows, or what a compliance error on an RFP actually costs you.

Software like Shred.ai is built by people who do. With 20+ years of AEC expertise behind it, a native integration with OpenAsset’s DAM, and AI fine-tuned by real proposal writers, it’s designed to solve the problems your team faces every single day.

If your firm is ready to spend less time on the hunt and more time crafting proposals that win, an AI proposal writing assistant is worth a look.
