The problem
Every time I had to write a proposal for a client, I spent 2-3 hours on it. Researching their brief, structuring sections, finding the right tone.
Most of the time the client had already hired someone else by the time I sent it.
So I built ProposalPilot.
What it does
You paste the client's project brief, pick your service type (web dev, design, marketing, consulting), and get a full personalized proposal in ~30 seconds. The output streams in real time so you see it being written, which feels surprisingly satisfying.

The stack
- Next.js 14 (App Router, Server Components)
- Anthropic Claude API for generation with streaming
- Supabase for auth + database (RLS on every table)
- Stripe for payments ($19/month Pro plan)
- Vercel for hosting
The streaming was the trickiest part — piping Claude's stream through a Next.js Route Handler to the client with ReadableStream and TextDecoder. Once it clicked it felt like magic.
Where it is right now
This is an early version. The core flow works end-to-end but there's a lot still rough:
- Templates could be smarter per niche
- No PDF/Word export yet
- The pricing section outputs a placeholder (you fill in your number)
- Mobile needs work
What I'm trying to figure out
The technical side feels solid. What I genuinely don't know yet is whether the output quality is good enough that a freelancer would actually send it with minor tweaks, or if it's the kind of thing you'd rewrite entirely.
If you're a freelancer or consultant, I'd love to hear your take — even a quick "this is usable" or "this needs work" in the comments helps a lot.
