Building in public, every day

KarunaHazarika

I build SaaS solo, in public: from the first commit to the first sale.

I shipped PeakPad, a Mac app that turns the MacBook notch into 29 tools, eighteen days after the first line of code. Now I'm building AI agents that do real work, starting with an AI editor. I share the code, the revenue and the mistakes along the way.

PeakPad

Turns the MacBook notch into a control centre with 29 tools: music with lyrics, clipboard, a file shelf, a teleprompter, your Stripe sales and your Claude Code usage. One payment, no subscription, no account.
