Started vibe coding last year. Shipped a thing. Then had no idea what to do next.
ChatGPT gave me a textbook. My founder friend gave me vibes. The investor I knew handed me his playbook for someone else's company. None of them knew my product. So I built Sensei.
One reading, one move, every Monday. Sensei reads your site, your rivals, the public web — and your real metrics when you wire Stripe or analytics. Then it gives you one verdict and one move.
The design call
Strategy tools default to dashboards: dense charts, KPIs in tiles, vanity metrics. I built Sensei in editorial grammar instead — Instrument Serif for voice, kanji watermarks at 0.04 opacity, pattern-notes with a 2px vermillion rail, paper-and-sumi palette. Not a dashboard. A reading.
Three things I rejected on purpose:
A trends dashboard. Founders don't need more data — they need a verdict on the data they have.
A chatbot wrapper. Sensei answers the question you don't know to ask, not the one you typed.
Gamification. No streaks, no badges. The reward is shipping the move.
The engineering call
Four lenses every week — Market Fit, Strategy, Presence, Edge. Each calls a different prompt against grounded inputs: site content via Jina Reader, real Lighthouse scores via Google PageSpeed Insights, competitive intel from public sources. Every claim traces to a measurable source or admits it can't read it yet.
Stack: Next.js · Supabase · AI SDK. Boring on purpose. The editorial product is where the taste went.
Launching this week. Free through May 31, $29/mo after.
