About Hillnote

Hillnote is a writing tool that thinks alongside you, rich editing, document linking, and AI working right beside you as you write. Local, private, and yours to keep. Hillnote is where you craft your thoughts in notes, drawings, databases and plans, powered by AI that runs on your device (even when you're offline). No rented database, no lock-in, your work stays yours, even without us. Claude Code, Cowork, Codex, and other agents read, edit, and act on the same files you do, directly, no exports.

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.
