About Envy

Envy is a free, fast Markdown notes app for Mac. Every note is a plain .md file stored locally, no account, no sync service, no subscription, no lock-in. 6.0 MB. Source is public to read; the code is proprietary. Every note is plain Markdown in a single folder we call The Index. Press Return to open the top match, or to create a note from what you just typed. Operators narrow it: tag: due: todo: Search is not a feature.

About Wattfare

Users connect, set a spending cap, and you call any model through one SDK, charged to them, not you. OpenAI-compatible Works with the Vercel AI SDK ~5-min integration. One button connects a user's inference budget to your app, metered, capped, and revocable. The problem AI costs are the one line item you can't predict. Every AI app makes the same uncomfortable bet: price high enough to survive your power users, ration usage so nobody hurts you, or quietly lose money on the heavy ones.
