/cache
Your notes, thinking for you.
Fully offline. Fully autonomous.
The Four Pillars
Built different. By design.
No compromises on privacy. No dependency on the cloud. No ceiling on intelligence.
Everything stays on your machine.
Your notes, your AI, your hardware. /cache runs entirely locally — no sync servers, no telemetry, no third-party eyes. What you write is yours, forever.
AI ready when you are.
Background agents work while you sleep — surfacing connections, drafting summaries, flagging gaps. Wake up to a smarter vault, not a to-do list.
Built for the agentic era.
/cache understands your notes as a living knowledge graph. Ask anything. Get answers rooted in what you've actually written — not what the internet thinks.
Your notes, working for you.
It's not just storage. /cache connects ideas across weeks of writing, drafts follow-ups, and reminds you of threads you dropped. The second brain, finally real.
Feature Highlights
Show, don't tell.
01 — AI CHAT
Ask your vault anything.
A local AI assistant that knows your entire note history. No context window limits on your data. No data sent anywhere.
→ Raft consensus — 3 notes, unresolved: leader election edge case
→ CRDTs vs OT — you flagged a paper to revisit
→ Your own latency benchmarks, 2 drafts
Want me to surface the open questions?
02 — DIFF REVIEW
Approve or reject AI edits.
AI-suggested changes are shown inline as diffs. You stay in control — review, approve, or reject at a line level. Nothing changes without your say.
03 — VAULT ANALYSIS
Catch me up on anything.
Query across your entire knowledge base. /cache synthesizes answers from your own writing, with sources you can trace back to the original note.
04 — EDITOR
Markdown, without the friction.
A WYSIWYG editor that stays out of your way. Write in plain markdown or rich text — /cache renders it live. Tagging, linking, and backlinks built in.
The Privacy Promise
No cloud. No telemetry. No third-party servers.
Your notes never leave your machine. Ever.
The AI runs on your CPU. Not ours.
This is not another app that sends your data somewhere. This is your machine, working for you.

Your second brain,
now thinking for itself.
Free for macOS. No account. No cloud. Just download and start writing.
