About this app

Hillnote is where you think.

A local-first, markdown-native workspace that captures your work in AI-native formats — notes, plans, drafts, ideas, decisions. Built on plain markdown, stored on your device, paired with your desktop, and ready for the AI tools you already use.

Built for builders, makers, writers, and small teams who think on the move and want their workspace to come with them.

Write as you think, the way you think. A clean markdown editor designed for capture, not arrangement. A floating toolbar above the keyboard handles formatting; standard markdown shortcuts (#, -, 1.) work out of the box.

Quicknotes for everything in between. Tap + to capture an idea the moment it lands. Save and it's in your workspace; keep typing if you want to expand it. No friction between a thought and a file.

Your thinking stays on your device. Every file lives locally as plain markdown. No rented database, no required account, no lock-in. Your work is yours from day one, and yours if you cancel.

Free sync across phone, tablet, and desktop. The first 100MB syncs free — more than enough for years of notes. Capture on your phone, expand on your desktop, review anywhere.

Talk to your knowledge base. Built-in chat reads your own files, edits them, creates new ones, and pulls context from your workspace. Upload images and have them read. Auto mode picks the right model; switch manually when you want to.

Supercharge your writing with Local Intelligence. Native integration with writing tools powered by local intelligence built into your device — proofread, rewrite, reformat — via the ✨ keyboard button or text selection.

Workspaces with all the context AI models need. Hillnote automatically generates context files (AGENTS.md, CLAUDE.md, document registries) so any AI tool you connect can navigate your workspace immediately — no setup, no plugins.

Pairs with the agents you already work with. Claude, ChatGPT, Codex, Cursor, Cowork, Claude Code — connect via local or cloud MCP, or point them at the workspace folder directly. Plain markdown means no exports, no conversions. They read and edit the same files you do.

Carry your tools, not just your notes. Build small HTML tools — pomodoro timers, day counters, focus checklists, anything else — that travel inside your workspace. Pin them as widgets. Your tools live next to the work they support.

A different model. We separate what's a service from what's yours. You subscribe to the workspace and pay for cloud features (expanded sync, frontier AI, publishing, routines, BYO key) only when you need them. Free accounts include limited premium model usage. Your data stays on your device as plain markdown, always canonical, always portable.

Start free. Sync free. Stay local. Add cloud when you outgrow it.

Download Hillnote and bring your thinking with you.

What’s new

Hillnote Feeds:
  • A new Feed tab resurfaces notes from your own library. Everything is built on your device, nothing is uploaded, no reading history is tracked, and it works fully offline, with Infinite scroll.

Better collaboration:
• Edit the same file together. Changes merge automatically, with a fallback when a conflict cannot be merged.
• A pill above the editor shows who is in the workspace with you.

Notepad:
• A scratch pad that slides over any note you are editing.
