AI Product Strategist

Things I'm Building

Side projects, experiments, and tools — from first hypothesis to shipped product. Each one tests an idea in public.

ProductBud
🟡 Beta

ProductBud

A suite of LLM-based tools to validate startup ideas.

Pressure-test your assumptions before you build. ProductBud puts a set of LLM-powered tools behind the hardest part of a new idea — sharpening the problem, stress-testing demand, and getting to real evidence fast, without a full research cycle.

Validation, not vibes. Evidence before you build.

Writing Horror app
🟡 Beta

Writing Horror

Stop staring at the blank page. Start writing.

A writing tool that doesn't tell you what to write — it gets you to actually write. Real-time pace tracking nudges you when you slow down, visualizes your words-per-minute, and keeps you in the chair. When you're done, paste your session into your manuscript and move on. Works for any genre. The horror is just the soundtrack.

Doesn't write for you. Gets you to write.

Kid Chef app
🟡 Beta

Kid Chef

One step at a time cooking for kids.

A full-screen mobile app that breaks recipes into single, focused steps. It reads instructions aloud, adjusts portions to kid-friendly measurements (half a cup, not 118ml), runs timers in-app, and shows visual guides — all one thing at a time. Immersive and distraction-free, so kids just focus on what they're making right now.

Built for kids who get overwhelmed, not just entertained.
