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.
