AI Proposal Generator: What Free Gets You, and What Signing Costs (2026)

An AI proposal generator is a tool that turns a short brief into a drafted client proposal: the scope, the timeline and the price. You describe the client and the job in a sentence or two, and it hands back the document you would otherwise rebuild from last month's proposal. Some design it as well. A few will send it and collect the signature.

Search for one and Google returns a page of free generators. On 9 October 2026, eight of the nine organic US results for "ai proposal generator" were free generator pages from companies whose paid product is something else. The paid products behind them range from a design suite and proposal software to a general AI agent, HubSpot document automation, a writing tool and a template library.

Nothing wrong with that; the generator is the sample. The trouble is that "free" means something different on every page. On one it gets you a PNG, on another text you copy, and on a third an account and fourteen days before the paywall.

So I read most of the generator pages that rank, and the pricing pages behind them, on 9 October 2026. The first table shows what free gets you; the second prices the upgrade to a proposal your client can sign. If you would rather build your own proposal agent from call notes and past SOWs, that has its own guide.

How I compared them

I read six of the eight page-one generator pages, plus Qwilr's and Bookipi's, and the pricing pages behind them on 9 October 2026, taking the monthly and the annual price wherever a page offered both (Nextdocs: annual view only). Eight of the nine tools' pricing pages open on the annual price, so most prices here come in pairs: that default and the monthly figure. Five questions did the sorting: account, what the AI does, the file you leave with, whether the client can sign, and what one seat costs.

What I did not do: generate a proposal. Nobody ran a brief through these tools for this post, so nothing here judges how well they write; every claim is what the vendor's own page says. QuillBot's page data carried several different monthly prices, so I quote only its annual one.

The listicles ranking for "best AI proposal software" come from vendors, and GetAccept's, Bookipi's and Civio's each rank their own product first. None of them says what free means on each generator page.

Three page-one results get one line here. Nextdocs, a general AI document and slide generator, allows up to 3 exports on its free plan, as of October 2026. Canva and Template.net, a design tool and a template site, also rank; I did not read them. Qwilr and Bookipi miss page one for this search; Qwilr's AI Creator is named in its AI Overview, and Bookipi in the AI Overview for "best ai proposal software". PandaDoc and Better Proposals are the upgrade path a weekly sender ends up comparing.

Quick comparison: what free actually gets you

Read on each vendor's own pages on 9 October 2026. Ranks are Google US organic positions for "ai proposal generator" unless noted. Prices in US dollars, as of October 2026.

Read two columns first. Account tells you whether the tool wants your email before your brief, and e-signature tells you whether the result can close a deal or only describe one.

The upgrade path: entry plans for one seat

Send proposals every week and you will end up paying for one of these. Each row is the entry paid plan for one seat, as of October 2026, with two exceptions: Bookipi's starts at its free plan, and Venngage's row is Business, its first plan with PDF export.

Read 9 October 2026, in US dollars. Proposify bills non-annual Build by the quarter. Bookipi's monthly figures come from a US read of its pricing page, and Manus's cards carry no plan names.

One freelancer, eight proposals a month: what a year costs

Here is one illustrative workload, not data from anyone's business: a freelancer on one seat sends 8 proposals a month, each ready for the client to e-sign, for 12 months. List prices as of October 2026:

• Portant Free plan: $0, if your proposals start from HubSpot, Google or Office templates. It allows 30 documents a month with a single e-signature on each. The AI fills fields and you write the pitch; Pro would be $42 × 12 = $504 a year on annual billing.
• Bookipi: US$64.99 a year. The free plan covers 3 signatures a month, so 8 needs the Contract Pro 10 Pack. Whether that add-on needs a paid base plan is not stated. The cheapest route here that pairs an AI writer with signatures, on paper, caveat attached.
• Better Proposals Starter: $156 a year. Eight sends fit inside the limit of 10: $13 × 12 = $156 annual, $19 × 12 = $228 monthly. No AI writer is listed.
• PandaDoc Starter: $228 a year. The free plan's 60 documents a year cover only 5 a month, so you need Starter: $19 × 12 = $228 annual, $35 × 12 = $420 monthly. The AI Assistant is included.
• Venngage Business: $288 a year, with no e-signature listed. The PDF alone needs Business: $24 × 12 = $288 billed yearly.
• Proposify Build and Qwilr Starter: $420 a year each. $35 × 12 = $420 annual; non-annual, Proposify is $147 × 4 = $588 and Qwilr is $49 × 12 = $588.

Now look at who does the writing. Portant's $0 route fills in fields, and Better Proposals lists no AI writer. Bookipi pairs a writer with signatures for less, with an open question attached. Set Bookipi aside until that is answered, and the cheapest plan here with an AI writer and enough signatures for this workload is PandaDoc Starter, at $228 a year. On a tight budget, the answer is a pair: a free generator such as QuillBot or Portant's, plus a cheap tool that signs.

The cheapest signed proposal is not where the AI is.

1. Venngage: a designed proposal, exported as a PNG on the free plan

Venngage is a design platform, and its generator promises "a complete, designed business proposal, covering scope, timelines, and pricing with no design skills needed." You can also remix a template or upload a file to start from.

The PDF in the headline needs Venngage Business

The line under the page title says "Export as PDF, PPT or PNG". The FAQ on the same page is narrower: "Free users can generate a proposal, customize it in the editor, and export as PNG. PDF and PowerPoint export, private sharing, and Brand Kit features are available on paid plans." A PNG is a picture of a proposal, and a picture is awkward to sign. The free plan card adds two limits: 5 designs, and the AI listed as a "Free Venngage AI Trial".

Premium won't fix the export. Premium is $19 a month or $10 billed yearly, for unlimited designs and hi-res PNG export, as of October 2026. PDF export and "Venngage AI" itself sit on Business. No e-signature is listed on the generator or pricing page, and Venngage's own FAQ hands the deal cycle (e-signatures, CRM integrations, contracts and payments) to proposal software such as PandaDoc and Proposify.

2. Proposify: the free generator is a 14-day trial

Proposify's page ranks second under the heading "Free AI Proposal Generator", and its FAQ explains the free part: "Yes, you'll be prompted to create a free trial account to get started. You'll have 14 days to experiment with Proposify before being prompted to upgrade to a paid account." The product behind it is proposal software with e-signatures, tracking and integrations.

The trial needs no card, and the pricing FAQ says you can send real proposals to real clients during it. Inside the editor you paste "your call notes, meeting transcripts, project requirements, and rough ideas" and prompt the AI to draft, refine or rewrite sections such as the scope of work. Build also lists an "MCP server" for connecting Proposify to Claude.

Build is billed by the year or by the quarter

As of October 2026, Build is $35 a seat a month billed annually, or $420 a year. Flip the toggle to Monthly and the card shows $49, while the line beneath still reads $147 a seat a quarter or $420 a year. The shortest billing period on the page is a quarter.

Best for

A small team sending proposals every week that wants drafting, signatures and tracking in one tool.

E-signature

"Every plan can add signatures to documents to get legal sign-off." Build includes unlimited documents and signatures.

Bigger plans

Grow is $325 a month billed annually with 5 seats, and Scale is $1,066 a month billed annually with 10, both sold through a demo, as of October 2026.

3. Manus: a general AI agent that researches the client first

Manus is a general-purpose AI agent, and its proposal maker is one of its "Playbooks": a fill-in prompt for the client, project type, scope, timeline and budget, plus upload boxes for an RFP or project brief and for meeting notes, in PDF or Word.

It is the only generator here that says it researches your prospect. Manus "actively browses the web" to study the prospect's industry and competitors, and says most standard business proposals are generated within five to ten minutes. You refine the result by conversation and export the finished document.

Manus does not print what one proposal costs in credits

The FAQ offers "up to 300 free credits for new users" and says a standard proposal "typically uses a modest number of credits", with no figure attached. The paid cards show prices and no plan names. The entry tier is $20 a month, or $17 billed yearly, for 4,000 credits a month plus 300 refresh credits a day; the next two are $40 ($34 yearly) and $200 ($167 yearly), as of October 2026. Neither page lists sending or signing.

4. Portant: no signup, and the AI writes no clauses

Portant automates documents for teams in HubSpot, Google Workspace or Microsoft Office, "with the templates you already use." Its generator needs no signup. Describe the project and the client, and download as many proposals as you like, as an editable .docx or a one-click PDF.

Portant's AI fills the template and leaves the pitch to you

The FAQ says it plainly: "Does the AI write the whole proposal? No. It fills a structured template with your details: the parties, dates, term and signature blocks. It never writes or changes clauses, so the document stays predictable." That is the opposite of Manus. The persuasive parts are yours to write.

Behind the generator sits a real free plan. Portant Free is free forever for one seat, with 30 documents a month, the HubSpot integration and a single e-signature per document, as of October 2026. Pro is $49 a month, or $42 billed annually, and adds multiple signatures per document; Team is $149, or $125 billed annually, with 5 seats included. Portant says there are "no per-signature fees."

Best for

Teams whose proposals already start from a HubSpot deal or a Google or Office template.

After it sends

If the deal lives in HubSpot, the HubSpot deal-stage nudge guide covers keeping it moving.

5. QuillBot: free proposal text, no account

One prompt in, proposal text out: QuillBot's generator, tagged "Beta", covers business, research, grant or academic proposals and is "Free to use with no sign-up required." The samples on the page run a short paragraph each.

The page lists no layout, no export format and no e-signature. Premium, $8.33 a month billed annually ($99.95 a year) as of October 2026, is not needed for the generator. Use it for the words, then check every figure in the scope and the price before a client sees it.

6. Qwilr: a proposal web page built from your own site

Qwilr builds proposals as interactive web pages, with video, dynamic pricing cards and ROI calculators. Paste your website link and the AI Creator, Qwilr says, scans the site "to understand your business, offering, messaging and design style," then builds a tailored page.

Sending the page starts a Starter trial

Generating is free and needs no account. Editing and sending need one, and that account is a 14-day trial of Starter with no card and no free plan after it. Starter comes with e-signature, analytics, QwilrPay, HubSpot, Zoho and Pipedrive integrations, and an "AI assistant integration (MCP)". Growth (from $275 a month for 5 seats) and Scale (from $750 for 10) are annual only, as of October 2026.

7. Bookipi: an AI writer and three free signatures a month

Proposal AI lives inside Bookipi, an invoicing app for small businesses on the web, iOS and Android. It drafts from your service details, and Bookipi says the proposals come "pre-populated with service agreements that are completely editable." The proposal and the invoice after it share one app, though chasing that invoice is its own job.

As of October 2026, the free plan is US$0 "forever" with no card: Proposal AI, 3 invoices a month and 3 e-signatures a month (the e-signatures reset every 30 days). The page does not say whether generating needs an account; its buttons lead to sign-up.

Paid plans still stop at three signatures a month

Starter (US$9.99 a month, or US$91.20 a year) and Professional (US$52.00 a month, or US$468.00 a year) both still print e-signatures as "Up to 3 per month", as of October 2026. More come from add-ons, read at annual prices: the Contract Pro 10 Pack is US$64.99 a year for up to 10 e-signed documents a month, and Contract Pro + is US$184.99 for unlimited. The page does not say whether an add-on needs a paid base plan. If it does, Starter plus the 10 Pack comes to US$91.20 + US$64.99 = US$156.19 a year. Ask Bookipi before you budget, and read the pre-filled agreement line by line. An AI-drafted term is still your term.

8. PandaDoc: AI drafting and unlimited e-signatures from $19 a month billed annually

Starter is where PandaDoc's AI Document Assistant switches on: the compare table marks it no on Free and yes from Starter up. The product is document workflow software for proposals, quotes, contracts, e-signature and payments, and the assistant drafts and refines copy inside its editor.

Business, at $65 a seat a month or $49 billed annually as of October 2026, adds custom quotes, CRM integrations, custom branding, a content library and approval workflows. The free plan allows 60 documents a year, a shared limit of 5 a month, and there is a 14-day trial with no card.

Automatic reminders start at PandaDoc Business

Auto reminders and recipient analytics are marked for Business and up. On Starter, chasing an unsigned proposal stays your job, and the PandaDoc proposal follow-up guide covers that stretch after you hit send.

Best for

A freelancer or small team sending more than 5 proposals a month who wants AI drafting and signatures on one bill.

Watch

The Claude and ChatGPT access is beta, offered "for a limited time" on every plan, and PandaDoc "reserves the right to introduce usage limits at any time."

9. Better Proposals: cheap signing, bring your own writer

Better Proposals is template-led proposal software with interactive pricing tables, and its Starter plan lists legally binding signatures, payment integrations and a content library. It lists no AI writing feature on its pricing page, homepage or "Create" product page, read 9 October 2026. The homepage does say "we have banned AI in our marketing, customer support and sales departments", a line about the company's own teams. Treat it as the template tool you pair with a free generator.

The send limit decides which plan you need

Starter's 10 sends a month fit the worked example, with two to spare. Premium ($29 a month or $21 billed annually, as of October 2026) allows 50 sends and unlimited seats, and Enterprise ($49 or $42) removes the limit. Follow-up automation is a $10 a seat a month add-on called Nudge. The trial is 14 days, with no free plan behind it.

Generator or software? The line is blurring through MCP

Three tools here now list a door for outside AI assistants. PandaDoc ticks "AI & Agents (Claude, ChatGPT & MCP)" on every plan and says its MCP server launched in September 2025. Proposify lists an "MCP server" for Claude, and Qwilr's Starter card lists an "AI assistant integration (MCP)". Proposify's own wording shows what MCP, the Model Context Protocol, is for: "Connect Proposify to Claude" and use it "to create and update documents."

Read together, the pages suggest a draft from Claude or ChatGPT can land in the tool that sends and signs. So choose that tool on signatures, send limits and price. Nobody tested these connections for this post.

Writing an RFP response, a grant or a job bid?

Three other jobs share the word "proposal", and this guide leaves them out.

• Formal RFP responses are a separate category of software, built around a library of approved past answers. The RFP response drafting guide covers them.
• Grant proposals are out of scope here, though QuillBot and Venngage both mention grants.
• Bids on Upwork-style job sites have their own "AI proposal writer" apps, and they are not covered.

Which one should you choose?

Start with how often you send, then ask whether the client has to sign. Prices are as of October 2026.

One proposal a month, no signature needed: QuillBot for the words, or Portant's generator for a .docx or PDF. Neither asks for an account.

A few signed proposals a month: Bookipi's free plan, with 3 e-signatures and an AI writer. Past three, price the add-on and ask whether it needs Starter.

Weekly proposals that need signatures: PandaDoc Starter, $19 a seat a month billed annually, puts AI drafting and unlimited e-signatures in one plan. If 10 sends a month is enough and you draft elsewhere, Better Proposals Starter is $13 a month billed annually.

A team on HubSpot or Google templates: Portant. Its Free plan covers 30 documents a month for one seat, and Portant Team is $125 a month billed annually for 5 seats. Sales teams comparing more than documents can read the best AI agents for sales teams.

A design-heavy pitch: Venngage for a document, at $24 a seat a month billed yearly for the PDF, or Qwilr for a web page, at $35 a seat a month billed annually once the trial ends. Agencies can see the rest of the workflow in AI agents for marketing agencies, and solo designers in the freelance designers guide.

A big pitch to a prospect you know little about: Manus, which reads the web before it writes.

A small sales team that wants one tool: Proposify Build at $35 a seat a month billed annually, or Grow at $325 a month billed annually for 5 seats.
