Proposal Rewriter & Checker
Paste your freelance proposal and get it rewritten more professionally. Uses Chrome's built-in AI to improve tone, clarity, and persuasiveness. Runs on your device — nothing is sent anywhere.
Smart Analysis Mode: The tool will provide word suggestions and proposal writing tips instead.
How the Proposal Rewriter Works
This tool uses Chrome's built-in Rewriter API with the more-formal tone setting to transform your freelance proposal into a polished, professional version. The AI improves vocabulary, sentence structure, and overall persuasiveness while keeping your original message intact. When Chrome AI is unavailable, the tool provides rule-based word upgrade suggestions, proposal length analysis, and actionable tips based on proven freelance proposal best practices. It checks whether your proposal mentions experience, timelines, and calls to action.
What Gets Improved in Your Proposal
The rewriter targets four key areas that separate winning proposals from rejected ones. Professional tone upgrades casual language like "I can do" to confident phrasing like "I will deliver." Clarity improvements turn vague statements into specific, concrete commitments. Persuasiveness enhancements strengthen your value proposition and add compelling calls to action. Structure improvements ensure your proposal flows logically from greeting through experience to closing. Proposals between 150 and 300 words with specific references to the client's project consistently outperform generic submissions.
Private Proposal Enhancement
Your proposal content is never sent to any server. Whether you are bidding on Upwork, Fiverr, or responding to a client RFP, your text stays completely private on your device. Chrome runs the Gemini Nano AI model directly on your hardware. The word suggestion engine and proposal analysis also run entirely in JavaScript within your browser. This protects your pricing strategy, client relationships, and competitive positioning from being exposed to third-party services.
Getting the Most from This Tool
Paste the full proposal, not a fragment — the checker scores length, and anything under 120 words reads as low-effort to a client reviewing 40 bids. Include the client's own project name in the text so the tone rewrite keeps it verbatim rather than genericising it. Run the check once before you edit and once after: the second pass tells you whether your edits actually added a timeline and a call-to-action or just reworded the opening. Keep the original in a separate note, because the rewrite replaces the input box. Everything runs locally, so it works offline after the first page load.
Proposal Checker: The 7 Things to Verify Before You Send
Use this as a proposal checker pass before submitting any bid. (1) Client's own words — mirror at least two exact phrases from the job post; generic openings are the single biggest rejection driver. (2) Specific deliverable count — "5 landing pages" beats "several pages". (3) A dated timeline, not "quickly" or "ASAP". (4) A price with its assumptions listed, so scope creep has a written boundary. (5) One measurable proof point — a past result with a number attached. (6) A single call-to-action with a date ("open for a 15-minute call Thursday or Friday?"). (7) Length between 150 and 300 words for platform bids. For government work the bar is formal: FAR 15.204 sets the uniform contract format federal buyers expect, and a response missing a required section is commonly rejected before it is ever scored. The analysis panel above flags the items it can detect automatically — experience mentions, timeline language, and call-to-action presence — so you can fix gaps before a client sees them.

Free Proposal Template Examples You Can Paste and Rewrite
If you do not have a proposal yet, start with one of these free proposal template structures and paste it into the input box above — the rewriter will turn it into a polished, client-ready version. Upwork bid proposal template: "Hi [Client Name], I read your post about [project]. I have [X years] of experience in [skill] and have delivered [number] similar projects. I can complete this in [timeline] for [budget]. Would you be open to a quick 15-minute call to discuss?" Cover letter proposal template: "Dear [Hiring Manager], I am applying for the [role] you posted on [platform]. My background in [field] aligns with your needs because [specific match]. Attached is my portfolio with three relevant samples. I am available to start on [date]." RFP response proposal template: "Executive Summary — [Your Company] proposes to [solve problem] for [Client] within [budget range] over [timeline]." These three templates align with the structure recommended by the SCORE small-business proposal guide (SBA-affiliated nonprofit). Updated 2026-07-02.
Proposal Template Structure: What Wins Contracts in 2026
The seven-section proposal template that wins the most Upwork, government, and enterprise contracts follows a fixed order: (1) Executive Summary (2-3 sentences on the problem you solve), (2) Client Understanding (mirror their exact language from the RFP or job post), (3) Proposed Solution (deliverables with quantities), (4) Timeline (Gantt-style milestones with dates), (5) Pricing (fixed vs hourly with assumptions listed), (6) Relevant Experience (three case studies with metrics), and (7) Call-to-Action (a specific next step with a date). Per the US Federal Acquisition Regulation FAR 15.203 — the standard governing federal RFP responses — proposals missing an executive summary or pricing section are non-responsive and get rejected at intake. Paste your draft above and the rewriter will restructure loose prose into this seven-section format automatically.
Frequently Asked Questions

Yes. This tool uses Chrome's built-in AI which runs entirely on your device. Your proposal text is never sent to any server.
What types of proposals can I rewrite?

Where can I get a free proposal template?
The H2 above includes three free proposal template structures (Upwork bid, cover letter, RFP response) you can paste directly into this tool to rewrite. They follow the SCORE/SBA recommended format with greeting, problem, solution, timeline, and call to action.
What is the best proposal template for freelancers?
For freelance platforms like Upwork and Fiverr, the highest-converting proposal template is: 1) client-specific opener (mention their project), 2) 1-2 sentences of relevant experience, 3) concrete timeline and price, 4) call to action for a 15-minute call. Keep it under 300 words — over-long bids consistently underperform.
What sections must a government RFP proposal template include?
Per US FAR 15.203, a compliant federal RFP response needs: Executive Summary, Technical Approach, Management Plan, Past Performance (three references with contract values), Pricing with assumptions listed, and required certifications. Missing any of these makes the proposal non-responsive and triggers automatic rejection at intake — before evaluators even review the content.
What does a proposal checker actually check?
This proposal checker scans for the signals clients screen on: overall length, whether you mention relevant experience, whether a delivery timeline appears, and whether the proposal closes with a call to action. It flags weak or casual word choices and suggests stronger replacements. It does not judge your pricing — that is a business call — but it will tell you if the proposal reads as generic.
Should I use a proposal checker before or after rewriting?
Both. Run the check first to see which of the seven elements are missing, add them yourself, then run the rewrite to tighten tone and wording. Rewriting first tends to polish a proposal that is still missing a timeline or a call to action — it reads better but converts no differently. Checking first fixes substance, rewriting second fixes delivery.
How long should a proposal template be for enterprise B2B deals?
For enterprise deals above $50,000, proposals average 12-25 pages: 1-page executive summary, 3-5 pages on solution + methodology, 2-3 pages on timeline + milestones, 1-2 pages on pricing, 3-5 pages on team + case studies, plus appendices. For deals under $10,000, keep the proposal template to 2-4 pages — buyers at that price point reject long-form proposals as overkill.
