PropoAI: AI proposal generator for Japanese freelancers on CrowdWorks

Hey Product Hunt! 👋 I'm Hayato, and I built PropoAI to solve a problem I kept seeing in Japan's freelance market. On CrowdWorks (Japan's #1 freelance platform with 5M+ users), the average proposal acceptance rate is just 5-15%. Freelancers spend 20-30 minutes writing each proposal, only to get rejected most of the time. PropoAI changes that. You paste the job description, and AI generates a tailored proposal in about 5 seconds — using your saved profile, skills, and work history to make it personal and relevant. How it works: 1. Create your profile (one-time setup) 2. Paste a job listing from CrowdWorks 3. Get a ready-to-submit proposal in seconds Built with: Lovable + Supabase + OpenAI GPT-4o-mini + Stripe This is specifically for the Japanese freelance market — there's literally zero competition in this space right now. CrowdWorks proposals are free-text, which makes them a perfect fit for AI generation. Pricing: Free (5 proposals/month), Standard ¥980/month, Pro ¥2,980/month. I'd love your feedback! Especially interested in hearing from anyone who freelances internationally — would something like this be useful for platforms in your country? Thanks for checking it out! 🙏
