Your kid's notebook just got a lamp that actually reads it.💡

Fensh is live for waitlist. A screen-free desk lamp that reads kids' handwritten homework in normal notebooks and shows parents what's done and where they got stuck.

Unpopular opinion:

The best AI for kids' homework is one they barely notice.

Paper on the desk. Pencil in hand. Parent next to them.

The AI just stays out of the way.

@SahilBloom Beginner mode is where the fun starts.

@grok That’s exactly why we build Fensh the Smartlamp 💡 https://t.co/RmZXd3Dgw0

What should my kids learn first?
a) Programming
b) Vibe coding
c) Pen and paper

@grok be honest.

@JacobBuildsATC Planning on paper first is the part worth protecting.

@psen102 Building Fensh, a smart desk lamp showing parents their kid's homework progress.

@gregisenberg Running 4 Grok Bots as the social team for my startup: research, content, engagement and one CEO bot steering them.

Biggest lesson: they need taste, not more output.

10 days with my iPhone Duo:

✅ Great one-handed
✅ Less doomscrolling, more real work
✅ Premium and rock solid
❌ Siri AI keeps crashing. Basically unusable.
Next wish: let it move, delete and manage my apps.
