Native Mac. Connects Claude, Cursor, or Windsurf to your notes in one click. Built on a simple belief: writing is how you think — better notes make better thoughts.
Connects to the AI tools you already pay for
How it works
Your Markdown notes are the substrate that makes your AI smart about you. Eyrie fixes the three things that get in the way.
01 · The context problem
MCPClaude and Cursor are brilliant, but they start every conversation from zero — no memory of what you've decided, tried, or already written. Eyrie connects them to your notes folder in one click, so the AI you already pay for finally has context.
02 · The maintenance problem
⌘EEvery vault eventually becomes a swamp — half-thoughts, scattered drafts, an inbox that grows and never shrinks. Eyrie is purpose-built for keeping the substrate sharp: Smart Categories auto-classify, semantic search finds anything, ⌘E rewrites inline. Maintenance is the leverage.
03 · The trust problem
⌘⇧AWhen the AI claims you've "argued before that X," you need to see which note. Eyrie ships a clickable chip for every file the AI reads. Click to verify. No invented citations, no confident lies. Every AI edit shows you a diff before it touches disk.
Our belief
Writing is a tool for thinking. If we can build a tool that helps you write and organize your ideas more effectively, we help you have better thoughts — and solve otherwise intractable problems. Eyrie exists to be that tool.
Built for
Ask Eyrie about your customer notes, decisions, retros. Every answer ships with chips you can click to verify. No hallucinated authority, no invented citations — exactly what you wrote, when you wrote it.
"Three months ago I argued for usage-based pricing. What did I write? Why did I switch?"
Two of your October customer-interview notes contradict it — three users said they preferred one-time over freemium for tools they'd use daily…

"Pull last quarter's notes on the Acme retainer. Draft this month's status update in the same voice they liked."
Clip articles by URL. Cross-reference notes from months ago. Ask the agent to draft an outline from your reading, then refine inline with ⌘E.
"That essay I was drafting in October — the one I gave up on. Find the three good paragraphs and rebuild around them."

Features
Every AI surface is summoned, never imposed. Every edit is gated. Every retrieval is cited.
SwiftUI + AppKit. Launches instantly, sips memory, feels right at home on macOS.
Local NLEmbedding vectors fuse with BM25 scoring. HyDE rewrites queries before retrieval.
No proprietary blocks, no cloud lock-in. Your notes are a folder of plain Markdown on disk.
Every agent-proposed change appears as a diff. ⌘↵ accepts, ⌘⌫ rejects. Nothing auto-applies.
Bookmarked folders, document outline (⌘⇧O), unlinked mentions, tag browser. Polish you'd expect.
Paste a link in chat. Eyrie fetches it via Jina Reader, strips noise, proposes saving it.
Why Eyrie
Most AI-notes apps lock your data into their cloud and your wallet into a monthly fee. Eyrie does neither.

A note from the founder
My Markdown notes are how my AI gets smart about me. Across a dozen projects — startups, code, research, journals — the notes are the substrate Claude, Cursor, and Windsurf read when they need to know what I've already decided, already tried, already written.
The better that substrate is — organized, well-categorized, rewritten for clarity — the better every AI conversation goes. A messy vault means generic answers. A sharp vault means an AI that actually knows my situation.
So the real work isn't taking notes. It's maintaining them. Finding what I wrote six months ago. Reorganizing the inbox. Rewriting clunky paragraphs. Auto-categorizing as I go. Each one of those tasks compounds every AI answer I'll get later.
No existing tool treated notes that way. Notion locked them in a cloud. Obsidian + plugins meant assembling seven things on top of Electron. Mem put them behind a subscription. None of those are the substrate I want my agents reading from.
So I built Eyrie: a native Mac editor purpose-built for keeping your Markdown vault sharp — search, organize, rewrite, restructure — all with AI built in. Then any agent (Claude Desktop, Cursor, Windsurf) connects to that vault in one click.
The notes are the leverage. Eyrie maintains them. Your AI compounds.
