Hillnote

Hillnote is a writing and planning workspace for people who want local files and AI help inside their editor. It keeps your work as plain Markdown on disk, readable by other editors and accessible to AI agents.

• Connected workspaces: Organize documents, databases, kanban boards, canvases and slides around the same Markdown files, with document links and scratch spaces for rough notes.
• Offline writing assistance: Use Ollama or Apple Intelligence for inline edits, rephrasing and brainstorming, with local model processing staying on your machine.
• Local and cloud AI: Choose local models or hosted models such as Claude and GPT; automatic routing can hand tasks to cloud models, which sends those requests off your device.
• Agent access: Claude Code, Cowork and Codex can read and edit the same files you use, while a built-in local MCP server connects compatible agents to the workspace.

Hillnote runs on Mac, Windows, iOS and Android. The core editor and local AI are free, and getting started doesn't require an account. The editor, workspace and local AI work fully offline; cloud services require a connection, and paid cloud services are available.

Sync is optional for each workspace. With sync off, each device keeps its own local copy. Enabling it makes the workspace available across devices, and a cloud MCP endpoint lets remote agents access synced workspaces.
