Idea test planner
Turn an idea into a question with a wrong answer worth knowing, weigh the evidence you already have, and leave with the smallest honest test that could settle it. It starts filled in with an example; replace any part with your own.
The utility drawer
One job. Done simply.
Small, focused tools for the work around the work. No sign-up, and no twelve-step onboarding tour.
Play over a chord
Pick a chord and a scale, let it ring, and play or sing over it. Every note you play lands on top of the chord and glows: green when it fits, amber when it adds tension, red when it clashes. Use your microphone, or tap the keys.
AI text humanizer
Paste text that sounds machine-written and get it back reading like a person wrote it: plainer words, no more “it’s not X, it’s Y”, contractions, fewer em dashes, shorter sentences, and optional typos or a social-post layout. It all happens in this browser; nothing you paste is sent anywhere.
