Best Free AI Proposal Generators in 2026

Eleven tools are compared below on one specific question: what do you actually get without paying. Four offer a genuine free forever plan. The other seven are paid tools with a free trial, typically fourteen days, and no permanent free tier. Both are legitimate ways to test a tool, but they are not the same thing, and the difference matters once you are mid way through building a real proposal. Plan details below reflect published pricing pages as of August 2026. Free tiers and trial terms change often, so confirm current details before you commit to one.

1. Proposal.biz

Proposal.biz’s free plan is genuinely free forever, not a trial, and no credit card is required to start. It includes AI document generation from a prompt or a pasted website URL, a drag and drop editor, e-signatures, and send and track opens, capped at fifty documents, twenty five pages per document, and one thousand AI credits, across three content library sources.

Key features:

• AI document generation from a prompt or a pasted website URL
• Drag and drop document editor with built-in e-signatures
• Send and track opens on the free plan, no paid add-on required
• Free forever: 50 documents, 25 pages per document, 1,000 AI credits, 3 content sources, no credit card

That combination is what sets it apart from the rest of this list. PandaDoc’s free tier covers signing but not AI drafting, and Quillbot covers drafting but not signing or tracking. Proposal.biz’s free forever plan puts document generation, branding pulled from a pasted URL, e-signing, and open tracking on the same no cost plan, with paid tiers starting at $19 a month adding custom branding, a custom domain, and more seats.

For a wider look at how AI proposal generators are changing this category, the fuller guide covers what to expect beyond this list.

2. PandaDoc

PandaDoc’s free plan is genuinely free forever, not a trial. It caps you at a small number of documents a month, with unlimited e-signatures and a basic document editor, but no AI content generation, which sits behind the paid tiers.

Key features:

• Genuinely free forever plan, not a time limited trial
• Unlimited e-signatures included on the free tier
• Basic document editor for building and formatting documents
• No AI content generation on the free plan, capped monthly documents

The free tier is built around signing rather than drafting. If you already have a proposal written and mainly need a professional way to get it signed, the free plan covers that without a time limit. Paid plans start at $19 per user per month and add templates, tracking, and a content library, with AI drafting features appearing further up the pricing ladder.

3. Quillbot’s AI Proposal Generator

Quillbot offers a free, no signup AI tool that drafts a proposal from a short prompt. It is a drafting tool rather than a full platform, so there is no sending, tracking, or signing built in, just the written draft.

Key features:

• Free AI drafting tool, no account or signup required
• Generates a written draft from a short prompt
• Plain text output only, no branding applied
• No sending, tracking, or e-signing built in

This is the simplest entry on the list and the easiest to test. There is no account required and no time limit, but the output is plain text you still need to brand, format, and send through another channel. It is best treated as a fast first draft generator rather than a proposal platform.

4. Venngage

Venngage is a design led tool with a free forever tier for building a proposal from a visual template. The free plan limits which templates and export options are available, with fuller access sitting behind a paid plan.

Key features:

• Free forever tier for template based proposal design
• Visual, drag and drop layout editor rather than AI generated copy
• Limited template selection and export options on the free plan
• Full export options require a paid plan

Venngage suits a proposal where visual layout matters more than AI generated copy. You are choosing and customising a template rather than generating structured content from a prompt, which makes it a different category of tool from the AI drafting generators above, closer to a design tool that happens to include proposal templates.

5. Proposify

Proposify has no permanent free plan. It offers a fourteen day free trial that includes its AI writing assistant, letting you draft, refine, and rewrite sections directly inside the editor before the trial ends.

Key features:

• Fourteen day free trial, no permanent free plan
• AI writing assistant for drafting, refining, and rewriting sections
• Locks down approved content, pricing, and legal language
• AI assistant works from pasted notes rather than a website URL

Proposify is built around locking down approved content, pricing, and legal language so a sales team cannot accidentally send an outdated version. The AI assistant works from pasted call notes or requirements rather than a website URL. Paid plans start at $35 per user per month.

6. Qwilr

Qwilr has no permanent free plan, only a fourteen day trial with no credit card required. It separately offers a free AI tool that scans your website to produce a first draft, which is a lead generation tool rather than a full free tier.

Key features:

• Fourteen day free trial, no credit card required
• Separate free AI tool that scans your website for a first draft
• Turns proposals into interactive web pages rather than static documents
• Embedded video, dynamic pricing, and section level engagement data

Qwilr’s core product turns a proposal into an interactive web page rather than a static document, with embedded video, dynamic pricing, and analytics on which sections a client actually engaged with. Paid plans start at $35 per user per month, with a ten seat minimum on the Enterprise tier.

7. GetAccept

GetAccept does not currently offer a permanent free plan. A free trial is available, though the length is not consistently stated across GetAccept’s own materials, so confirm the current terms before you rely on it.

Key features:

• Free trial, length not consistently stated
• AI drafted content for proposals during the trial
• Shared digital sales room combining proposal, video, and e-signing
• Real time tracking of document and signer activity

GetAccept is built around a shared digital sales room where a proposal, video messages, and e-signing all live in one space with the buyer. Entry level pricing starts at $25 per user per month for e-signing specifically, with fuller proposal and deal room features on higher tiers.

8. Nusii

Nusii offers a fourteen day free trial and no permanent free plan. It is built as a simple, no frills proposal builder, positioned as one of the more affordable dedicated tools once the trial ends.

Key features:

• Fourteen day free trial, no permanent free plan
• Simple, no frills proposal builder
• Browser based editor with a light learning curve
• Built for speed and simplicity over advanced automation

Nusii’s focus is speed and simplicity over design flexibility or advanced automation. If your priority is a browser based builder without a steep learning curve, the trial is enough to judge whether the editor fits your workflow. Paid plans start at $29 a month.

9. Better Proposals

Better Proposals runs a fourteen day free trial with no credit card required and no permanent free plan. It is positioned toward freelancers and small teams who want a fast, templated design without a design background.

Key features:

• Fourteen day free trial, no credit card required
• Fast, templated designs aimed at freelancers and small teams
• Full access to your chosen plan’s features during the trial
• No permanent free plan once the trial ends

The trial gives full access to the plan you sign up under, so what you can test depends on which tier you pick at signup. Paid plans start at $13 per user per month on the entry tier, with proposal volume and features expanding on the higher tiers.

10. Storydoc

Storydoc offers a fourteen day free trial with no credit card required and no permanent free tier. Anything built during the trial reportedly stays accessible afterward, though full functionality requires upgrading.

Key features:

• Fourteen day free trial, no credit card required
• AI assisted drafting for narrative, presentation style proposals
• Interactive elements closer to a pitch deck than a static document
• CRM integrations and custom branding gated to paid tiers

Storydoc leans toward narrative, presentation style proposals with AI assisted drafting and interactive elements, closer to a pitch deck than a traditional document. Paid plans start around $17 to $19.80 a month, with CRM integrations and custom branding gated to higher tiers.

11. Proposable

Proposable offers a free trial with no permanent free version. Entry level paid plans start at $19 per user per month and include a capped number of monthly proposal deliveries alongside a shared content library.

Key features:

• Free trial only, no permanent free version
• Capped number of monthly proposal deliveries on entry plans
• Shared content library for reuse across documents
• Aimed at solo users and small teams sending a moderate volume

Proposable is a simpler, more affordable option aimed at solo users and small teams sending a moderate volume of proposals a month. The trial is the only way to test it without paying, and the free version does not exist as a standing option.

For a broader look at options built with smaller budgets and teams in mind, proposal software for small businesses covers that angle in more depth..

How to Choose Between Them

Four questions narrow this list fast: do you need a permanent free option or is a trial enough, do you need AI drafting and signing together or just one of them, do you need an interactive web page or a standard document, and how many documents do you realistically send a month.

Question	Why it narrows the list
Free forever or trial acceptable?	Proposal.biz, PandaDoc, Quillbot, and Venngage stay usable with zero ongoing cost. Everything else needs a decision within the trial window.
AI drafting and signing, or just one?	Proposal.biz’s free plan covers both drafting and signing together. PandaDoc’s free tier covers signing, not drafting. Quillbot covers drafting, not signing.
Static document or interactive page?	Qwilr and Storydoc build interactive, web based proposals. The rest produce a more conventional document.
How many documents a month?	A free tier document cap ranges from a couple a month on some tools up to fifty on Proposal.biz’s free forever plan, so check the cap against your realistic volume.

For more options beyond the ones covered here, the curated list of the best proposal software tools breaks down where each platform’s strengths lie.

If tracking sent documents matters most to you, a closer look at proposal tracking software specifically covers that angle in more depth.

Final Word

Proposal.biz is the one tool on this list where AI drafting, branding pulled from a URL, sending, tracking, and e-signing all sit on the same permanent free plan at once, a combination that sits behind a paid tier everywhere else here. What differs among the rest of the list is which single piece of the workflow each free tier or trial actually covers.

Match that against the one thing you need most right now, document signing, a fast AI draft, or a visually polished template, and start there. If all you need is a fast way to create and send proposals without juggling a separate signing tool, Proposal.biz’s free forever plan is the one worth trying first.

Frequently Asked Questions

Which of these has a genuinely free plan, not just a trial?

Proposal.biz, PandaDoc, Quillbot’s AI proposal generator, and Venngage all offer a permanent free tier. The other seven, Proposify, Qwilr, GetAccept, Nusii, Better Proposals, Storydoc, and Proposable, require a paid plan once their free trial ends.

Which free tool actually generates the proposal content with AI?

Proposal.biz and Quillbot’s AI proposal generator both draft content from a prompt for free. Proposal.biz adds branding pulled from a website URL, sending, tracking, and e-signing on the same free plan, while Quillbot produces plain text only, with no sending, tracking, or branding built in. PandaDoc’s free tier covers signing rather than AI drafting.

Do any of these free plans include e-signatures?

Yes. Proposal.biz’s free forever plan includes e-signatures alongside AI drafting and tracking, and PandaDoc’s free forever plan includes unlimited e-signatures too, though without AI drafting. Most of the trial based tools include signing during the trial period, but it typically requires a paid plan afterward.

How long do the free trials on this list usually last?

Fourteen days is the most common length, used by Proposify, Qwilr, Nusii, Better Proposals, and Storydoc. GetAccept and Proposable offer a trial without a consistently stated length, so confirm current terms directly.

Is a genuinely free plan always better than a trial?

Not necessarily. A free forever plan is better for indefinite, low volume use, and a higher document cap, like Proposal.biz’s fifty documents, narrows the gap further. A trial gives you fuller functionality to properly test a tool before deciding, which matters more if you need to evaluate features a capped free tier does not include.
