Built different. By design.

No compromises on privacy. No dependency on the cloud. No ceiling on intelligence.

PRIVACY

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.

🔒
AGENTS 24/7

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.

KNOWLEDGE

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.

SECOND BRAIN

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.

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.

Catch me up on my research notes from last week
cache
Last week you wrote 12 notes on distributed systems. Key threads:

→ 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.

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.
