You're not losing jobs because you're bad. You're losing them because of your proposal.On Upwork, clients see 50+ proposals per job. Most get ignored in the first sentence — because they're generic, too long, and obviously written by AI.This tool fixes that. It's not another "ChatGPT wrapper" that spits out the same robotic paragraph everyone else sends. It's built on the actual data behind proposals that get replies.What it does differently✅ Hits the 150–250 word sweet spot — the proven range for the highest Upwork reply rates.✅ Finds and answers the client's screening questions — 70% of rejected proposals ignore them. This tool extracts them automatically and weaves the answers in.✅ Sounds like YOU, not a bot — paste one writing sample and it mimics your real voice. This is the single biggest factor in not getting flagged as AI.✅ Built-in reviewer — after writing your proposal, it tells you the exact 2-minute human edit that turns a good draft into one that wins.✅ Tells you which work sample to attach — proposals with a targeted sample get 35% more replies.✅ Works for Upwork, cold email, and LinkedIn — each with the right length and tone.How it works Set up your profile once (name, skills, past wins, writing sample) Paste any job description Get a tailored, human-sounding proposal in ~30 seconds Refine with one keystroke and send Honest about what this isThis runs on your own Claude API key (free to create — costs about $0.005–$0.01 per proposal, billed directly by Anthropic).
