DraftPilot — RFP Response Builder for Boutique Agencies Who Lose Bids to Copy-Paste
Boutique creative and dev agencies spend 15+ hours manually writing RFP responses that sound identical to every competitor because they are copy-pasting last quarter's pitch deck. DraftPilot ingests the RFP PDF, matches it against your agency's past wins, and generates a fully tailored first draft that actually references the client's specific language.

What is it?
Small agencies (5-30 person shops) lose RFPs not because they lack capability but because their responses are generic — they do not have time to rewrite from scratch per bid. DraftPilot is a web app where an agency uploads an RFP PDF and their portfolio of past winning proposals. Claude RAG then identifies which past work matches the RFP requirements, extracts the client's own language and pain points from the RFP, and generates a structured draft that mirrors the RFP's evaluation criteria section by section. This is not a generic AI writer — it forces the output to reference the specific scoring rubric from the uploaded RFP. Priced at $79/month per agency. Buildable now because Claude's 200k context window handles 50-page RFPs easily without chunking complexity, and PDF parsing with pdf-parse is a solved npm package.
Why now?
Claude's 200k token context window launched in late 2025 and now handles full 50-page RFP documents in a single prompt without chunking — this was not reliably possible 12 months ago and is the technical unlock that makes this product viable.
- ▸RFP PDF upload with automatic evaluation criteria extraction (Implementation note: Claude prompt targets numbered scoring rubrics specifically).
- ▸Past proposal library stored as vector embeddings for semantic matching against new RFPs.
- ▸Section-by-section draft generation that mirrors the RFP structure exactly.
- ▸Editable draft in a rich text editor with inline source attribution showing which past proposal each section drew from.
Target Audience
Boutique creative, marketing, and dev agencies with 5-30 staff who respond to 2-10 RFPs per month, roughly 80k such agencies in the US.
Example Use Case
A 12-person UX agency uploads a 40-page government contractor RFP alongside their 5 best past proposals. DraftPilot generates a 15-page response draft with their past case study on a similar project embedded in the relevant section, using the RFP's exact evaluation language as headers.
User Stories
- ▸As a boutique agency owner, I want to upload an RFP and get a draft that mirrors its evaluation criteria, so that my response scores higher on the rubric.
- ▸As an agency operations manager, I want past winning proposals stored as a searchable library, so that relevant case studies surface automatically in every new draft.
- ▸As a proposal writer, I want to see which past proposal each draft section drew from, so that I can verify accuracy before editing.
Done When
- ✓RFP parsing: done when evaluation criteria sections appear as labeled headings in the draft output matching the uploaded RFP structure.
- ✓Proposal matching: done when each draft section shows an inline citation linking to the source past proposal it referenced.
- ✓Draft generation: done when a complete section-by-section draft is visible in the editor within 4 minutes of upload.
- ✓Paywall: done when the third RFP upload triggers Stripe checkout and access is restored after payment.

What's the competition?
Competition Level
Low
Similar Products
Loopio targets enterprise at $500/month, Proposify is a proposal builder not an RFP drafter, Responsive.io requires enterprise contracts — all miss the boutique agency price point.
Competitive Advantage
Proposify and PandaDoc are proposal builders, not RFP responders. Loopio targets enterprise at $500+/month. DraftPilot is the first RAG-native tool priced for boutique agencies.
Regulatory Risks
Low regulatory risk. Uploaded RFPs may contain confidential client information — data isolation per agency account is critical. GDPR: data deletion endpoint required.
What's the roadmap?
Feature Roadmap
V1 (launch): RFP upload, proposal library, section-by-section draft, rich text editor. V2 (month 2-3): DOCX export, team editing, compliance checklist. V3 (month 4+): win-rate analytics, CRM sync.
Milestone Plan
Phase 1 (Week 1-2): PDF parsing, pgvector setup, Claude RAG pipeline working end-to-end. Phase 2 (Week 3): editor UI, Stripe billing, agency auth. Phase 3 (Month 2): 10 paying agencies, DOCX export shipped.
How do you build it?
Tech Stack
Next.js, Claude API with RAG, pdf-parse, Supabase with pgvector, Stripe — build with Cursor for RAG pipeline, v0 for UI.
Suggested Frameworks
LangChain for RAG orchestration, pdf-parse for PDF extraction, Supabase pgvector for embedding search
Time to Ship
3 weeks
Required Skills
RAG pipeline with pgvector, PDF parsing, Claude API, Stripe billing.
Resources
LangChain docs, Supabase pgvector guide, Anthropic long-context docs, pdf-parse npm.
MVP Scope
app/page.tsx (upload and dashboard), app/api/parse-rfp/route.ts (PDF to text), app/api/match-proposals/route.ts (pgvector similarity search), app/api/draft/route.ts (Claude RAG generation), lib/db/schema.ts (rfps, proposals, drafts tables), lib/embed.ts (OpenAI or Claude embedding helper), components/DraftEditor.tsx (rich text with source citations), components/UploadZone.tsx (drag-and-drop PDF upload), .env.example.
Core User Journey
Upload RFP PDF -> upload 3 past proposals -> receive structured draft in under 3 minutes -> edit in rich text editor -> export to DOCX.
Architecture Pattern
PDF upload -> pdf-parse extracts text -> Claude extracts evaluation criteria -> pgvector embeds and stores past proposals -> similarity search finds matches -> Claude generates section-by-section draft -> stored in Postgres -> displayed in rich text editor.
Data Model
Agency has many Proposals and many RFPs. RFP has one Draft. Draft has many Sections. Section references source Proposals via embedding match.
Integration Points
Claude API for RAG generation and criteria extraction, Supabase pgvector for embedding storage and similarity search, pdf-parse for PDF text extraction, Stripe for billing, Resend for email delivery of completed drafts.
V1 Scope Boundaries
V1 excludes: DOCX export, team collaboration, compliance checklist, white-label, CRM integration.
Success Definition
A paying agency owner uploads an RFP, receives a draft they describe as better than their own first draft, and submits it to the actual bid.
Challenges
Distribution is the killer — agency owners are busy and skeptical of AI writing tools, so the demo must show a before-and-after on a real RFP in under 60 seconds to convert.
Avoid These Pitfalls
Do not try to make the output submission-ready in V1 — position it as a first draft accelerator or users will expect perfection and churn. Do not skip data isolation between agency accounts — one agency seeing another's RFP is a trust-destroying bug. Finding first 10 agencies is the hard part; do manual demos before automating anything.
Security Requirements
Supabase Auth with Google OAuth. RLS enforcing agency-level data isolation on all tables. Rate limit: 10 drafts/hour per agency. Input validation on file uploads (PDF only, 50MB max). GDPR: full data deletion per agency on request.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres with pgvector and file storage, GitHub Actions for CI/CD, Sentry for error tracking, dev and prod Vercel environments.
Performance Targets
50 DAU at launch, 100 drafts/day. Draft generation under 4 minutes. Dashboard loads under 2s. pgvector similarity search under 500ms.

First Run Experience
On first run: a demo RFP (fictional 15-page marketing services bid) and 2 sample past proposals are pre-loaded. User can immediately click Generate Draft and see a complete section draft in 2 minutes. No manual config required: demo mode requires no auth or file upload.
How to build it, step by step
1. Define Supabase schema for agencies, rfps, proposals, drafts, and sections with pgvector extension enabled. 2. Build PDF upload and pdf-parse extraction in app/api/parse-rfp/route.ts. 3. Generate embeddings for past proposals and store in pgvector via lib/embed.ts. 4. Build similarity search in app/api/match-proposals/route.ts returning top 3 matching past proposals per RFP section. 5. Write Claude prompt in app/api/draft/route.ts that takes RFP criteria plus matched proposal excerpts and generates section drafts. 6. Build DraftEditor.tsx with Tiptap rich text editor and inline source citation display. 7. Build UploadZone.tsx with drag-and-drop for both RFP and past proposal PDFs. 8. Add Stripe billing with 2 free draft limit and paywall modal. 9. Deploy to Vercel with Supabase connection pooling configured. 10. Verify: upload a real 20-page RFP and 2 past proposals, confirm draft generates section-by-section with source citations visible in under 4 minutes.
