Show HN: Product Hunt AI Coach – AI voice Agent that remembers you

Hey HN,

We have built a Product Hunt Launch Coach, an AI voice adviser that remembers your product details and gives step-by-step guidance for each stage of a Product Hunt launch.

What you can do

- Talk instead of type: The site uses the Voice AI Agent to guide you through product hunt launch. We have added a knowledge base using 1000 top launch dataset (posts, comments, up-vote curves) with an LLM to surface patterns—timing, headline formulas, hunter involvement, etc. That helps this coach to help you frame positioning, share tips and guide you at every step - Memory that sticks: It stores your product name, audience, and launch date, so follow-up questions build on earlier chats without repeating yourself. - Launch playbooks: Pre-launch checklist, hour-by-hour launch-day plan, plus a curated list of 100 + communities (Discords, sub-reddits, forums) and email/DM templates for hunters and influencers. - Post-launch ideas: Tips on converting PH traffic into ongoing sign-ups and testimonials.

How it works - Front-end: Next.js + React. - Voice layer: Cartesia - Back-end: Claude Sonnet 3.7 for reasoning, with a small RAG layer built from manually researched best-practice docs and high-scoring launch examples (no scraped PH API yet). - State & auth: Supabase (PostgreSQL) for saved sessions; all voice + product data stays in your account.

Try it - Live demo (10 min free, no email needed): https://buildinpublic.buzz/ - Lifetime access: US $99 one-time.

Looking for feedback on - Whether the memory feature feels reliable. - Extra data points or launch assets you’d like it to track.

Thanks for checking it out! I’ll be in the thread all day to answer questions.
