Run the deterministic Proposal & RFP Analyzer without signup. When you need a new draft,
start a no-card 14-day Arc trial and build from the RFP, brief, notes, and source files you trust.
Gixo Arc offers two starting points for proposal work: a free anonymous deterministic analyzer for an existing draft, and a no-card 14-day Arc trial for AI proposal generation. The analyzer stays free; the trial ends. Arc drafts from the source material you provide, while your team remains responsible for facts, scope, pricing, and final approval. After the trial, new AI generation requires a paid Arc plan.
Proposals Arc wrote, with the inputs it was given
This is what the trial's AI generation produces. Arc wrote these on 3 October 2026 from a buyer's document, a bidder's evidence file and the deal terms shown, and exported each as a PDF and a Word file without editing. The bidder and the buyers are invented, and every cover says so.
A proposal for an invented regional retailer: the buyer's own untested estimate of what stock-outs cost it (described as untested), what the supplier will deliver and own, the data connections and implementation approach, the launch timeline, a first-year price built from the bidder's rates, two case studies and the team.
The brief and the inputs Arc was given
Propose weekly shop dashboards and a head-office comparison view to Fenwick & Dale Stores on behalf of Larkfield Analytics Ltd, with the supplier owning the data connections to the till, stock and loyalty systems. In any requirements table list only what the buyer's brief asks for; Larkfield's own standards belong in the method. Build every price line from the standard rates in the evidence file and show the days or months behind it. Add nothing the evidence file does not state. Put a notice on the cover page that the buyer and the bidder are fictional and the proposal is a worked example. Inputs: the buyer's document (brief-fenwick-dale.md); the bidder's evidence file (larkfield-evidence.md); commercial terms: value 52,000 to 60,000 GBP, valid for 60 days, payment terms 'Invoiced monthly in arrears, payable within 30 days.'; deal context: The buyer and the bidder in this proposal are fictional, and this proposal is a worked example. The buyer's out-of-stock cost of 5 to 7 percent of weekly sales in its three busiest shops is the buyer's own untested estimate and must be described as such. The first dashboards must be in shop managers' hands within 14 weeks.
A separate reviewer agent read its 178 claims against the bidder's evidence file, the buyer's brief and the deal terms: 142 are supported, 36 add detail or an inference, none is absent from every input and none contradicts one. Every price line recomputes. It is not a person's review.

RFP response: resident feedback and service analytics, Marlow Borough Council RFP 2026-14
A response to a council's request for proposals, written for an invented bidder: a cover letter, an executive summary, an answer to each of the ten mandatory and three desirable requirements, the team, two local-authority references, and a price built from the bidder's day rates and unit rates, with every line showing its days or units.
The brief and the inputs Arc was given
Respond to Marlow Borough Council's request for proposals RFP 2026-14 on behalf of Larkfield Analytics Ltd. Answer each mandatory requirement R1 to R10 and each desirable requirement D1 to D3 in turn, using the supplied evidence file for the company, delivery team, past performance, rates, assurance and declarations. Then add a short section that shows where the response answers each evaluation criterion (method, delivery team, past performance, data protection and security) and price. Build every price line from the standard rates in the evidence file (the days of each role times the day rate, or the units times the unit rate) and show the days or units behind each line. Add nothing the evidence file does not state, and do not refer to appendices or attachments that the response does not contain. Put a notice on the cover page that the buyer and the bidder are fictional and the response is a worked example. Inputs: the buyer's document (rfp-marlow-council.md); the bidder's evidence file (larkfield-evidence.md); commercial terms: value 296,000 to 318,000 GBP, valid for 60 days, payment terms 'Invoiced monthly in arrears, payable within 30 days.'; deal context: The buyer and the bidder in this response are fictional, and this response is a worked example. The response is for a 24-month contract with an option to extend for 12 months, within the buyer's budget ceiling of 330,000 pounds excluding VAT.
A separate reviewer agent read its 150 claims against the bidder's evidence file, the council's RFP and the deal terms: 132 are supported, 16 go a little beyond an input, 2 are in no input (it calls the price fixed, and it cites a 1,950-word limit nobody set) and none contradicts one. Every price line recomputes. It is not a person's review.
Each proposal was read against its inputs by a separate reviewer agent, not by a person; the counts are on each card. Replace every invented name, price and commitment with approved material from the real opportunity before anything is sent. The free analyzer does not generate text: it checks a draft you already have.
What does an AI proposal generator do?
Arc's proposal-type section plans give your draft a buyer-focused structure.
Buyer-aware sections
Problem, scope, deliverables, timeline, pricing, risks, terms. The structure follows how decisions get made, not how doc templates are organized.
Scope discipline
In-scope and out-of-scope are first-class sections. Avoid the proposal that quietly absorbs scope creep before the contract is even signed.
Editor with edit history
Generate the first draft, then refine inline. Tone shifts, rewrites, and inline suggestions — all tracked, same editor as Gixo Quill.
What is free, and what needs a paid Arc plan?
The analyzer and the Arc trial solve different starting problems.

How do I start using the AI proposal generator?
1
Choose analyze or create
Analyze an existing draft without signup, or start the Arc trial when you need new writing.
2
Paste or upload the brief and sources
Paste or upload the brief, the RFP and your source files: client name, the problem, what you propose to deliver, ballpark scope and timeline. The generator builds the first draft from them.
3
Review before delivery
Check facts, scope, pricing, and commitments, then export the reviewed proposal to PDF, DOCX, or HTML.
Frequently asked questions
Is the proposal generator actually free?
The Proposal & RFP Analyzer is free without signup. AI proposal generation is included in a no-card 14-day Arc trial; after the trial, new AI generation requires a paid Arc plan.
What kinds of proposals can I write?
Agency, consulting, professional services, retainer, project-based, scope-of-work — Arc supplies a section plan for the selected proposal type. Review pricing tables and timelines before sending.
Is this a separate product from Gixo Quill?
Yes. Gixo Arc is the proposal and RFP response product. Gixo Quill is the writing and content product.
Can I edit the draft once it's generated?
Yes. The same editor used for articles is used here — inline rewrites, tone shifts, suggestion-based edits, edit history.
Can I export to a client-ready format?
Yes. Arc exports reviewed proposals to DOCX, PDF, and HTML, with themes applied to exports.
Where should I start free?
Use the free analyzer when you already have a draft. Start the 14-day Arc trial when you want Arc to create a new source-grounded proposal draft.
Is there a truly free AI proposal generator from Gixo?
Arc offers a no-card 14-day trial for AI proposal generation. The deterministic analyzer remains available without signup, while ongoing AI generation after the trial requires a paid plan.
What sections does Gixo Arc put in a generated proposal?
Problem, scope, deliverables, timeline, pricing, risks, and terms, with in-scope and out-of-scope treated as first-class sections rather than an afterthought.
