8 best AI proposal writers in 2025: Which one suits your business?

best proposal writer

I’ve been in the SaaS world for a while, and if there’s one thing I’ve learned, it’s that technology should make your life easier, not more complicated. For small business owners and freelancers, that means spending less time on the tedious stuff and more time on what you actually love.

That’s why I’m always looking at tools that truly make a difference. The world of proposals used to be a huge time sink, but with AI business proposal templates and generators, that’s all changed. I’ve seen some great solutions coming out, and it’s clear that AI is transforming how we do business.

What is an AI proposal writer?

An AI proposal writer is a tool that uses artificial intelligence to help you create proposals. Think of it as a smart assistant that takes your raw information and turns it into a professional, persuasive document in minutes. Instead of starting from a blank page or a generic, boring template, you input a few key details about the client, the project, and your services.

The AI then drafts a polished proposal for you, complete with a professional structure, compelling language, and a clear call to action. It’s about leveraging technology to save you a ton of time and get you to “sent” faster.

These tools are no longer just for big companies; they are designed for the solo operator and small business owner who needs to work quickly and look professional.

Why use an AI proposal solution?

An AI proposal builder automates the most time-consuming parts, like drafting content, formatting, and making sure the tone is right. It also helps with consistency. With an AI-driven proposal creation tool, every proposal you send out looks professional and on-brand, even if you’re a solopreneur wearing all the hats. It gives you the credibility you need to stand out from the competition.

Leveraging an AI proposal tool gives you a serious competitive advantage when it comes to winning new business proposals. I’ve seen so many freelancers struggle with this. They’ll spend hours on a proposal for a project they might not even get, and that time adds up. AI sales proposal tools are designed to solve this exact problem.

What AI proposal builder features do you need?

Customizable templates

You need more than just a template; you need an AI business proposal template that you can easily edit and brand. Look for tools that let you swap out logos, color schemes, and fonts. Being able to quickly tailor the content to each client is the main benefit of these tools.

Content generation and automation

The core of any good AI proposal builder is its ability to draft content from a simple prompt. For example, it should be able to write sections for project scope, timelines, and pricing based on a few details. Look for platforms that can even generate content for different sections, like the introduction, deliverables, or testimonials.

E-signatures

This is a non-negotiable feature for me. The ability to send a proposal and have it signed digitally in the same tool streamlines the entire process. It cuts down on back-and-forth emails and ensures you can close deals faster.

Invoice and payment integrations

Why should a client have to go to a separate system to pay you? An AI proposal solution with integrated invoicing and payment processing makes it easy for your client to pay you as soon as they sign the proposal. This reduces payment delays and helps you manage your cash flow.

At the end of the day, the best AI tools for proposal creation are the ones that save you time and help you win more business. I’m excited about how platforms like Bookipi and others are making these powerful features accessible to everyone. We want you to focus on your craft, not your paperwork.

What are the top AI proposal writers?

1. Bookipi Proposal AI

Bookipi Proposal AI is an AI-driven proposal generator that’s designed to take the time and stress out of creating proposals. My team is passionate about making business management simple, and this tool is a great example of that. We’ve designed it to be smart, fast, and, most importantly, integrated into your workflow.

Professional-grade proposals in seconds

I’ve seen so many small business owners and freelancers struggle with the time it takes to write a good proposal. With our AI proposal builder, you don’t have to start from scratch. You just give it a simple prompt with the project detail, and it instantly generates a professional, well-structured proposal. The tool drafts the content for you, from the problem statement to the solution and a call to action. It’s all about creating a polished, high-quality proposal in minutes, not hours.

Customizable with your business details

A generic proposal isn’t going to stand out. That’s why we made it easy to customize the AI-generated proposals. The tool pulls your company’s branding, so you can add your logo and use your brand colors. You can edit every section of the draft to ensure the content is accurate and perfectly tailored to your client’s needs. This means you get the best of both worlds: the speed of AI with the personal touch of your brand.

Integration with our business management tools

The true magic of Bookipi Proposal AI is how it works with our other tools. It’s part of a connected ecosystem that helps you manage your business from end to end. Once your proposal is ready, you can use our built-in e-signature feature to get it signed electronically. Once it’s signed, you can instantly turn it into an invoice with our invoicing tool. It simplifies your entire workflow, from winning a client with an AI sales proposal tool to getting paid with the Bookipi invoice app.

What are the pros of using Bookipi Proposal AI?

  • It’s a free AI proposal generator, so you can create professional proposals without any cost.
  • You can create a professional, high-quality proposal in minutes, saving you valuable time.
  • It simplifies the entire process by providing a pre-filled service agreement and being fully editable.
  • The tool is part of the Bookipi ecosystem, allowing for seamless integration with other tools like invoicing and e-signatures.
  • You can easily customize the proposals to match your brand.

What are the cons of using Bookipi Proposal AI?

  • It may not have the deep analytics and advanced features that some enterprise-level solutions offer.
  • The tool is relatively new, so it has fewer third-party integrations compared to more established platforms.

2. Piktochart

Piktochart is a design tool that has integrated AI features to help users create visually appealing documents, including business and research proposals. It can generate proposals from a text prompt or from an existing document by transforming it into a more visually engaging format.

What are the pros of using Piktochart for AI proposal writing?

  • Many reviews praise its intuitive, drag-and-drop interface, making it accessible for non-designers.
  • It’s great for turning text-heavy content into visually appealing documents with charts, graphs, and images.
  • The free plan offers a certain number of AI credits per month, allowing users to try the feature without a paid subscription.

What are the cons of using Piktochart for AI proposal writing?

  • The AI functionality is still in beta. It primarily focuses on design and formatting rather than sophisticated content generation like some other tools.
  • Piktochart doesn’t offer deep integrations for things like e-signatures or turning a proposal into an invoice within the same ecosystem.
  • Some advanced features and high-quality downloads are restricted to paid plans.

3. Qwilr

Qwilr transforms static documents into interactive, web-based proposals. Its main selling point is creating a modern, engaging experience for clients with embedded content like videos, interactive pricing, and e-signatures.

What are the pros of using Qwilr for AI proposal writing?

  • Users consistently praise the “beautiful,” “visually appealing,” and “interactive” nature of Qwilr’s proposals. 
  • The ability to embed interactive elements like dynamic pricing tables, ROI calculators, and videos is a huge plus for users. 
  • It integrates well with CRMs like Salesforce and HubSpot, which streamlines the process for established sales teams.

What are the cons of using Qwilr for AI proposal writing?

  • While the AI is great for design and layout, some users feel it’s not a true AI “writer” in the same vein as some other tools. It’s more of a design and automation tool that happens to have some content generation features.
  • Some users have pointed out that while the templates are great, the editing functions can be restrictive, and they’ve experienced some layout issues, particularly with PDF exports.

4. Hubflo

Designed for service-based businesses, Hubflo uses AI to help users create proposals and centralizes a variety of client management functions, including contracts, billing, and file sharing. Its AI proposal maker is designed to be fast and easy, helping users generate tailored proposals in seconds from a simple prompt.

What are the pros of using Hubflo for AI proposal writing?

  • Users frequently praise the convenience of having everything in one place—proposals, contracts, billing, and client communication. 
  • The AI proposal generator is free to use, which makes it accessible for businesses of all sizes to try out before committing to the full client portal solution.

What are the cons of using Hubflo for AI proposal writing?

  • Some users feel that while the interface is clean, there’s a learning curve to get it to work exactly how they want, especially when setting up the initial client portals.
  • Features like advanced branding, custom domains, and certain automations are restricted to higher-priced plans.
  • Similar to some other tools, Hubflo’s AI is more of a “builder” that formats and organizes content, rather than a sophisticated writer that can generate extensive, original copy.

5. Better Proposals

Better Proposals focuses on turning proposals into web-based documents that are visually appealing and easy for clients to sign and pay. Its use of AI is not in the form of a full-fledged content writer, but rather as an assistant for things like simplifying pricing or generating headlines based on user input. It primarily relies on professionally-written templates.

What are the pros of using Better Proposals for AI proposal writing?

  • Many reviews mention that it has saved them from creating clunky PDFs.
  • The pre-written, professionally designed templates significantly cut down on proposal creation time.
  • Users love the real-time tracking, which shows when a client opens the proposal and which sections they read and for how long. 

What are the cons of using Better Proposals for AI proposal writing?

  • The AI is not a full-featured content writer. Instead of generating a full proposal from a prompt, it’s more of an assistant for small tasks. 
  • Some user reviews mention that the interface can be “clunky” and “glitchy.” Specific complaints include difficulty with copy-pasting, issues with layout, and problems with the signature function not working correctly.
  • Some users on forums have expressed frustration with the inability to easily export proposals to a Word document for a client to redline.

6. Proposal Genie

Proposal Genie can create proposals for freelancing platforms like Upwork and Freelancer.com. It operates as both a web-based service and a Chrome extension. The tool’s main purpose is to automate the proposal writing process, taking a job description and a user’s profile details to generate a customized proposal in seconds. It focuses on increasing the volume of applications a freelancer can submit while maintaining quality.

What are the pros of using Proposal Genie for AI proposal writing?

  • Users consistently mention that the tool’s biggest advantage is speed.
  • It’s not a general-purpose AI writer; it’s tailored to the unique needs of freelancing platforms.
  • I’ve seen feedback from users who say the proposals don’t sound like they were written by a robot. 

What are the cons of using Proposal Genie for AI proposal writing?

  • This tool is focused on writing proposals for freelancing platforms and doesn’t offer other business management features.
  • While the tool is fast, some users have pointed out that the AI-generated proposals can feel a bit generic.
  • For very specific or complex job descriptions, the AI may not fully grasp the nuance. This means the initial proposal might require significant editing to address all the client’s needs.

7. QuillBot

Quillbot is primarily known for its paraphrasing and grammar-checking tools. It’s not a full-fledged proposal-making platform. Instead, it is a powerful companion tool that helps you polish and refine the language of your proposal. While Quillbot has an AI Project Proposal Generator that can create an initial draft, its true value for professionals lies in its ability to take your existing content and improve its clarity, flow, and tone.

What are the pros of using Piktochart for AI proposal writing?

  • Users on forums often say it’s great for adding a fresh perspective to a tired piece of writing.
  • Quillbot has a grammar checker, a summarizer, and a citation generator all in one platform.
  • A major benefit of Quillbot is that you can access most of its features on a free plan. 

What are the pros of using Piktochart for AI proposal writing?

  • Quillbot is a writing tool, period. It doesn’t handle any of the post-writing tasks like collecting e-signatures, processing payments, or organizing clients. 
  • Users sometimes say that while the AI is great at rephrasing, it can occasionally miss the nuances of your content, leading to a rephrased sentence that doesn’t quite fit.
  • Despite Quillbot’s “humanizer” tool, its output can sometimes sound too formal or robotic. 

8. Storydoc

Storydoc transforms documents into interactive, web-based experiences. It’s designed to replace static PDFs and PowerPoint decks with dynamic, scrollable documents that feel more like a mini-website. Its AI helps users structure and design these documents, but the platform’s core strength is its ability to create a visually rich and engaging experience that stands out from the competition.

What are the pros of using Storydoc for AI proposal writing?

  • While it doesn’t write a proposal from scratch, the AI excels at structuring a professional deck from a simple prompt.
  • Users often mention that Storydoc’s web-based format with animations, embedded videos, and dynamic charts makes their proposals incredibly engaging. 
  • A big selling point is the real-time tracking. Storydoc shows you not just who opened the proposal, but also how long they spent on each section and what they clicked on. 

What are the cons of using Storydoc for AI proposal writing?

  • Storydoc is hyper-focused on proposals and presentations. It doesn’t handle the other aspects of your business, like invoicing, contracts, or expense tracking. 
  • While the end result looks amazing, some user reviews mention that the unique, web-based editor takes some getting used to. 
  • For a solo operator or a small team, the cost can be a bit of an investment. Pricing is often on a per-seat basis, which can add up quickly compared to other tools with more flexible plans.

How to choose the ideal AI proposal software for your needs

Choosing the right AI proposal software is a big decision, and it’s about more than just a slick interface. It’s about finding a system that works for you, not the other way around. Here are some questions to ask yourself.

Does it fit into my workflow or create more work?

Based on most small business owners and solo operators that use Bookipi, you likely can’t spend all day jumping between different apps. You get a lead, you write a proposal, you send it, you get a signature, then you send an invoice. That whole chain needs to be seamless.

Some tools powerful for document management. They have a ton of features and templates, which is great if you have a large sales team with a dedicated admin. But for a small business owner, that level of complexity can be a pain point. You might still need a separate app for your invoicing and a third one for tracking expenses. That’s just a recipe for wasted time.

Will it save me money or add another expense?

Many of these AI tools promise the world, but they also come with a hefty monthly fee. I see a lot of them, like Storydoc, which focus on creating beautiful, interactive decks. They look fantastic, but they’re not always built for the budget of a small business. Their pricing can quickly get steep for the features you really need.

That’s why our approach is different. With Bookipi, you can use our core proposal maker for free, which is perfect when you’re just starting out or only need to send a few proposals a month. You can still generate professional, branded documents with the help of our AI without paying a dime. You only need to think about upgrading to a low-cost subscription when you’re ready to scale and need unlimited documents.

Am I a professional copywriter or a business owner trying to get things done?

A lot of proposal tools out there give you templates and say “good luck.” It’s still on you to fill them in, write the right sales copy, and make it sound good. This can be intimidating and time-consuming. You’re not a marketing major. You’re trying to run your business.

We designed Bookipi’s AI to solve this problem directly. You can just put in a simple prompt about your project, and the AI drafts a complete, professional proposal for you. It handles the details of the service agreement, the scope of work, and the legal terms. All you do is review and send it. You can, of course, edit it to match your own voice, but the heavy lifting is already done. This lets you focus on your clients instead of getting bogged down by the details of writing.

Use AI-driven proposal creation to expedite your sales process

Having the right tools won’t just help you get work done faster. It will streamline your entire workflow, letting you focus on what really matters. Instead of piecing together different apps that don’t talk to each other, you want an integrated solution that automates the whole process from start to finish. This is where a unified platform like Bookipi’s AI suite comes in:

  • AI contracts: The AI can help you draft a valid contracts and agreements in seconds, taking a winning proposal and turning it into an enforceable agreement with just a few clicks. This makes your entire sales cycle more efficient, from the moment you send a quote to the moment you close the deal.
  • Invoices and payments: With our invoicing software, you can turn a signed contract into a paid invoice. It’s a simple, streamlined process that gets you paid faster with options like online card payments and in-person tap-to-pay.
  • eSignatures: Bookipi’s eSignatures are fully integrated across all our documents, from proposals to contracts and invoices, ensuring a secure and legally-binding workflow from beginning to end.
  • Client pipeline: Our client management tools provide a clear, real-time overview of your sales process. This helps you manage leads and track their movement from initial contact to a signed contract and a paid invoice.
  • AI Website Builder: Establish your online presence with a professional, AI-generated website. It can link directly to your services and contact information, serving as the front door for your entire business ecosystem.
