Hillnote vs VibeDrift

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.

Your AI agent gets worse as your project grows. VibeDrift catches the drift, fixes it, and gives your agent the context to stop making it.

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 VibeDrift

Your AI agent gets worse as your project grows. VibeDrift catches the drift, fixes it, and gives your agent the context to stop making it. See exactly how it works, free to use and fully public. Mid-task, Claude Code and Cursor ask your codebase what it already does, and get an evidence-backed answer in under a second. With and without VibeDrift, graded by an independent pass, it only changes things when the model would've gotten it wrong, and we show where it did nothing.
