Prepare the source pack
Choose the proposal kind and supply the buyer brief, approved evidence, delivery assumptions and commercial terms. For RFP work, retain the issued requirements and separate known answers from missing evidence.
How to write a proposal with AI
Upload your source files, select a proposal type, and let AI generate a structured first draft. Edit collaboratively, then export to PDF or DOCX.
To write a proposal with AI: upload your source files (the RFP, past proposals, and scope brief), pick from Gixo's 21 proposal types across 6 categories, and generate a structured first draft with each section grounded in what you uploaded. Then edit in place, keep a human review step, and export to PDF or DOCX before sending.

Consulting proposal: repairs satisfaction measurement, Harbourside Housing Association
A ten-week advisory engagement for an invented housing association: situation, approach and phases, a requirement-by-requirement compliance matrix, deliverables, timeline, team, terms, and a fee built phase by phase from the bidder's day rates, with the days of each role shown.
Inspect the source brief or data
Propose a ten-week advisory engagement for Harbourside Housing Association, on behalf of Larkfield Analytics Ltd, that answers the association's brief: review the current repairs survey, recommend how to measure repairs satisfaction by contractor, and leave a reporting approach for the repairs team and the board. Build the fee for each phase from the standard rates in the evidence file (the days of each role times the day rate) and show those days. 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-harbourside-housing.md); the bidder's evidence file (larkfield-evidence.md); commercial terms: value 46,000 to 52,000 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 engagement lead presents to the buyer's board in the ninth week.
Read the sample review notes
A separate reviewer agent read its 177 claims against the bidder's evidence file, the buyer's brief and the deal terms: 115 are supported, 58 add design detail or an inference, 4 are in no input (it calls the fee fixed) and none contradicts one. Every price line recomputes. It is not a person's review.
Review the proposed response
Inspect scope, exclusions, requirements and price assumptions. Use reviewable edits and saved comparisons; an unresolved buyer question needs an owner or an explicit qualification.
Package the reviewed version
Inspect the actual PDF, Word or HTML output. Tracked delivery activity and a recorded deal outcome answer different questions; verify the recipient, permissions and current approval state before sharing.
Buyer requirements and response ownership
Keep buyer RFP files separate from bidder evidence and approved reusable answers. Inspect extraction coverage, requirement source locations, questionnaire previews and submission limits. Response work can carry an SME owner, due date, escalation owner and required reviewer decisions. Compare an addendum with the source before changing a response.
Commercial schedules and recurring totals
Review each line's quantity, rate, unit, optional status and one-off, monthly or annual recurrence. Inspect recurrence totals and the estimated first-year total separately. Currency, supplied tax input and commercial assumptions need review. When importing Business metrics, select and review the source values before applying them to the schedule.
Buyer edition and submission package
Choose the current saved response or an approved edition. Inspect retained attachments, filled questionnaires, the compliance matrix and the package preview. A release manifest identifies stored delivery bytes. For tracked links, review recipient access, expiry, password and permissions separately from delivery activity and the recorded opportunity outcome.
A draft or readiness check is not approval of pricing, legal terms or a delivery commitment. Arc proposal drafting does not imply CRM, CPQ or tax-calculation automation.

How do you write a proposal with AI?
From blank page to a reviewable proposal draft. Gixo drafts from your source material so every section starts closer to real context.
1
Choose Your Proposal Type
Select from consulting, sales, grant, business case, renewal, or RFP response. Each type uses a tailored structure and section flow.
2
Gather Your Source Files
Collect RFP documents, past proposals, scope briefs, or any reference material. The AI reads these to understand the opportunity and requirements.
3
Upload and Configure
Upload your files to Gixo. Add a brief description of the project, client, and any specific instructions for tone or emphasis.
4
Generate Your First Draft
Click generate. The AI produces a structured proposal with executive summary, scope, methodology, timeline, pricing, and terms -- all drawn from your uploaded context.
5
Edit and Refine
Use the built-in editor to adjust language, reorder sections, add details, or regenerate specific parts. Collaborate with teammates in real time.
6
Export and Send
Export the reviewed proposal as a formatted PDF or DOCX. Share via link or download for email delivery after your team approves it.
What does each step do when you write a proposal with AI?
The AI drafts the structure and the sections; you keep control of the shape, the context it uses, and the final sign-off. Evidence is bound to what you uploaded, and nothing is sent until you approve it.
| Step | What you do in Gixo | What the AI does | What you control |
|---|---|---|---|
| 1. Pick a type | Choose from 21 proposal types across 6 categories (sales, retention, professional services, partnerships, internal/funding, specialized) | Loads the matching section structure | The proposal shape and flow |
| 2. Add sources | Upload the RFP, past proposals, scope brief, or reference docs | Reads them to ground the draft in real context | What context the AI is allowed to use |
| 3. Generate | Click generate | Drafts exec summary, scope, methodology, timeline, pricing, terms; lists the files supplied for the draft for review | Nothing is sent yet; it's a first draft |
| 4. Review & edit | Revise wording, reorder, regenerate sections | Regenerates only the parts you ask for | Human sign-off before it leaves |
| 5. Export & send | Export to PDF or DOCX, share by link | Preserves headings and layout | Final approval and delivery |
What should you give the AI before it drafts?
Give it your source files first: the RFP you're responding to, past proposals that already won, and a scope brief describing the project and client. A draft grounded in those files beats a draft written from a blank prompt, because every section starts from your real context instead of generic filler.
What can AI NOT do when writing a proposal?
AI won't own your win strategy, your pricing rationale, or the differentiators that set you apart -- those are judgment calls only you can make. It can also produce confident errors, so a first draft always needs a human review step before it goes to a client. Gixo is built around that review step rather than around removing it.
Which proposal types can AI write?
Gixo covers 21 proposal types across 6 categories: sales, retention, professional services, partnerships, internal/funding, and specialized. You start with a no-card 14-day trial; after that, generation requires a paid plan.
Frequently Asked Questions
What types of proposals can I write with Gixo?
Gixo supports consulting proposals, sales proposals, grant proposals, business case proposals, renewal proposals, and RFP responses. Each type uses a dedicated structure optimized for that use case.
Do I need to upload source files?
Source files are optional but strongly recommended. Uploading RFPs, scope documents, or past proposals lets the AI ground its output in real context, producing far more relevant and accurate drafts.
How long does it take to generate a proposal?
Generation time depends on the proposal type and source material. Treat the output as a first draft that still needs human review before sending.
Can I edit the proposal after generation?
Yes. Gixo includes a full editor where you can revise text, reorder sections, regenerate individual parts, and collaborate with team members before exporting.
What export formats are available?
You can export proposals as formatted PDF or DOCX files, and also as HTML, Markdown, JSON, or plain text. PDF and DOCX preserve your structure, headings, and layout for professional delivery.
Can I try it before paying?
Yes. Gixo offers a 14-day free trial that lets you generate proposals and test the full workflow before upgrading to a paid seat.
How do you write a proposal with AI?

What can AI not do when writing a proposal?
AI won't own your win strategy, pricing rationale, or differentiators, and it can produce confident errors, so a first draft always needs a human review step before it goes to a client. Gixo keeps that human sign-off in the loop rather than removing it.
