PROPOSAL
✦ AI proposals that actually get replies

Stop losing jobs
to your proposal.

On Upwork, clients see 50+ proposals per job. Yours gets skipped in the first sentence — because it sounds like every other AI proposal out there.

Proposal Engine writes the one that sounds like you.

Features

Built on what actually wins replies

Not another GPT wrapper. Every feature is built around the data behind proposals that get clients to respond.

📏

150–250 word sweet spot

The proven Upwork range where reply rates peak. Most AI tools ignore this and write walls of text clients never finish.

🔍

Auto-extracts screening questions

70% of rejected proposals don't answer them. This tool pulls them from the job post and weaves answers in naturally.

🎙️

Sounds like you, not a bot

Paste one writing sample and Claude mimics your voice — rhythm, vocabulary, personality. The single biggest factor in not getting flagged as AI.

✏️

Built-in reviewer

After generating, it tells you the exact 2-minute human edit that turns a good draft into one that wins. That final touch is what actually closes.

📎

Tells you which sample to attach

One targeted work sample gets 35% more replies. The tool tells you exactly which one to send with each job.

From Product Hunt

What people are saying

★★★★★

"The screening question auto-extraction is genuinely clever. That's the piece most freelancers consistently screw up — refreshing to see a tool that treats it as the core problem."

Amine
Product Hunt
★★★★★

"Curious if it works for someone just starting out on Upwork with no real history to pull from yet — and turns out any writing sample works. That's exactly what I needed to hear."

B
Bedirhan T.
Product Hunt
★★★★★

"How does it actually learn my voice from just a few past proposals? Got my answer — it's not ML, it's Claude using your sample as a style anchor. Simple and it works."

Honest about what this is

This runs on your own Claude API key — create one at console.anthropic.com. You pay Anthropic directly, about $0.01 per proposal. Nothing goes through my servers. Your data stays yours.

No installation: double-click .exe, paste your API key once in Edit Profile, done. No tool can guarantee you'll win — but your proposal will never again be the generic one that gets skipped.

FAQ

Common questions

Do I need to know how to code?

No. It's a .exe file — double-click and it runs. No installation, no terminal, no Python.

What's the API key about?

The tool uses Claude AI to write proposals. Create an account at console.anthropic.com, generate a key, paste it once into Edit Profile. You pay Anthropic ~$0.01 per proposal — no subscription to me.

How does the "voice learning" actually work?

It's not machine learning. Claude uses your writing sample as a style reference in the prompt each time. It doesn't improve on its own, but you can update the sample anytime. Most people tweak it once after the first few outputs — that's usually enough.

What if I'm new to Upwork with no past proposals?

Doesn't have to be proposals — any writing works. Emails, LinkedIn posts, even a few sentences. Write 2–3 lines describing your skills the way you'd say it out loud. It's more about tone than volume.

Why not just use ChatGPT directly?

You can — but you'd be writing the prompt, fighting the word count, missing screening questions, and getting the same generic output everyone else gets. This bakes in everything that actually works.

Does it work outside Upwork?

Yes — Upwork, cold email, and LinkedIn, each formatted correctly for that platform.
