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 Stonefold

Companies are starting to let AI agents take real actions in their systems. Stonefold is the checkpoint that keeps those actions inside rules your organization approved, with human approval where you require it, an audit record of everything, and one switch that stops it all. Companies are starting to let AI agents take real actions in their systems: pay an invoice, update a record, adjust a machine, close a support ticket. An agent can be tricked by what it reads, and it makes mistakes even when nobody is attacking it.
