Freelance Proposal Helper (paste-only)

Paste a job post you are reading and get a plain-language client check plus three tailored 3-sentence proposal drafts. No scraping, no browser extension, no automation on any freelance platform.

Economics

Pricing example
$12 / month (Free tier: 3 bids/day)
Daily math
50 freelancers paying $12/month = $600/month ($20/day). High stickiness because it directly impacts their earnings.
Monthly projection
$600 - $1,500 / month

Audience and urgency

Audience: Top rated and aspiring freelancers on Upwork, Fiverr, and Contra trying to escape the race to the bottom.

Urgency: Freelancers spend 2-4 hours daily sending 20 proposals with <5% response rate. A tool that triples their interview rate has instant ROI.

MVP scope

  • ✓ Standalone web app only. The user copies text in by hand. Nothing reads or changes freelance-platform pages
  • ✓ Paste a job post and the client details the user can already see: flags budget and risk signals the user typed in (e.g., payment unverified, low hire rate)
  • ✓ Generates an opening hook that avoids typical AI cliches like "I hope this email finds you well"
  • ✓ Stores the user's own portfolio links and past case study blurbs for reuse in drafts
  • ✓ The user reviews, edits, and submits every proposal themselves on the platform
  • ✓ Paywall triggered after 5 free drafts with Stripe Customer Portal

Omitted features

  • - Do NOT scrape, crawl, or automatically read any freelance platform (Upwork's Terms of Service prohibit it)
  • - Do NOT build a browser extension or inject scripts into platform pages
  • - Do NOT auto-submit or auto-bid. Every proposal is sent by the user by hand
  • - Do NOT ask for platform credentials or read private client messages

Suggested stack

One-shot master prompt

Create a standalone web app called "Freelance Proposal Helper".
Hard rule: the app never scrapes, crawls, or automates any freelance platform, ships no browser extension, and never submits anything. The user pastes text in and copies drafts out by hand.
Requirements:
1. Input: Textarea where the user pastes a job description and the client stats they can see (Hire rate, Total spent, Country).
2. Client Risk Check: Flags client quality from the pasted text only (e.g. "Green: High payer ($45/hr avg)", "Warning: Low hire rate 22%").
3. Generation Engine: Produces 3 tailored proposal variants:
   - "The Portfolio Proof" (leads with a relevant case study)
   - "The Clarifying Question" (stands out by diagnosing an unmentioned problem)
   - "The Fast Action Prototype" (offers a 15-minute quick mockup)
4. Character & word count tracker (optimized for the first 150 characters a client sees in a mobile notification preview).
5. A "Copy draft" button for each variant. No "send" or "submit" button.
6. Stripe subscription paywall modal ($12/mo) with active test-mode toggle.
