Crows remember faces for years.
Corvux learns from your patterns — what you link, what you ignore, what you return to. Every interaction sharpens an intelligence that lives on your device.
Corvux agents now in early access
Meet Corvux.
Your second brain — with Corvux agents that work for you.
Your files stay on your disk. Your Corvux agents work quietly in the background — researching, drafting, connecting ideas across everything you've ever written. Bring your own keys, switch models whenever you like, walk away whenever you want. Nothing leaks. Nothing leaves. Nothing locks you in.

Why a crow
Four things crows do better than your tools.
We didn't pick the corvid because it looked sharp on a logo. Every Corvux design choice maps to something a real crow already does.
Crows connect ideas across territories.
A real graph sits underneath every note. Links, tags, similarity, paths between ideas — all first-class. Not a sidebar feature. The foundation.
Crows trust their flock — no one else.
Sync is strictly peer-to-peer. No Corvux server. No third-party relay. Ever. Your devices talk to each other directly, end-to-end encrypted.
Crows hide their shiny things.
Plain files on your disk. Keys in your OS vault. Local intelligence by default. Cloud is opt-in, key-bound, audited. The shiny things stay where you put them.
Corvux agents
Send your Corvux agents into everything you've ever written.
Your Corvux agents don't wait for a prompt. They work alongside you — in the background, on your machine — reading what you've written, following the threads you'd follow, bringing back what you asked for with every claim traceable to the note it came from. You stay in the chair. They do the legwork.
They research like you would.
Ask a Corvux agent a question — it walks the links you've drawn, pulls together what's relevant, and returns a draft. Every sentence carries a footnote back to the note it came from. Verifiable, not hallucinated.
They work where you do.
Agents run on the same machine your notes live on. Your private patterns — what you write about, who you talk to, what you avoid — never leave the device. No upload. No round-trip. No third party in the room.
They get sharper with use.
Every correction, accept, and ignore tunes a model that learns what good looks like — to you, not to the average user. The longer you work together, the better the agent fits. Your agent leaves Corvux smarter than it arrived.
Things you'll actually ask:
- Find every note from the last quarter about pricing, and surface the contradictions.
- Connect this paragraph to anything related I've ever written.
- Read my last two weeks of journal and tell me what I'm avoiding.
- Draft a reply to this email using context from my project notes.
- Build me a reading list from every book I've referenced this year.
More than a notes app
An operating system
for the way you think.
Capture, search, connect, recall — the everyday motions of a working mind, finally on tools that move at the speed you do.
Find ideas, not just words.
Ask in plain language; the right paragraph comes back, even if it doesn't share a single keyword.
Backlinks that mean something.
Every mention becomes a connection. The graph builds itself; the meaning stays yours.
Voice capture, when you press.
Push-to-talk only. The mic listens when you ask it to — never on its own. Privacy isn't a setting; it's the default.
Daily notes, journals, projects.
Templates for every cadence — morning pages, weekly reviews, meeting notes. Or none, if you prefer empty rooms.
Five platforms, one second brain.
Mac, Windows, Linux, iPhone, Android. Devices talk peer-to-peer. End-to-end encrypted. The cloud isn't invited.
Works offline. Always.
Plane, train, basement, blackout — your second brain doesn't care. Sync resumes the moment you do.
On your terms
No middlemen.
No exit fees.
Corvux is a tool, not a platform you have to escape from. The intelligence stays on your machine. Cloud is optional and unbundled. Your data, your keys, your way out — always.
Bring your own keys.
Want a frontier model in the loop? Add your API key. We never see it, never store it, never mark it up. You pay the provider directly — or skip cloud entirely. Corvux works with no key at all.
- Direct billing to the model provider — no Corvux subscription stacked on top.
- Keys live in your OS vault, not in our database. Removable in one click.
- Switch providers the moment a better one ships. Mix models per task.
- Going local-only? Hide the cloud panel and forget it exists.
Leave whenever you want.
Your data lives on your disk as plain text — readable by any editor on Earth. There is no proprietary database to extract from. No "export" button to remember. Walking away takes zero clicks: your files were always yours.
- Plain markdown. Open in any text editor, anywhere, forever.
- Your folder structure stays exactly as you organized it — we never rewrite it.
- Corvux holds no copy. The disk is the source of truth.
- No "premium tier" gates your own data. Every byte is reachable, day one.

Sync your second brain everywhere.
Carry your notes across every device you own — peer-to-peer, end-to-end encrypted, with no Corvux server in the middle. Pick what syncs where. See who changed what. Roll back bad merges before they cost you a paragraph.
- Selective sync — choose which folders ride to mobile, desktop, or both.
- Sync history and rollback — undo a corrupted merge in one click.
- Cross-network sync over your own private mesh, with white-glove setup.
- Multi-device profiles — work laptop, personal laptop, phone, all distinct.
Coming soon
Voice agents.
Have a conversation with your Corvux agent. Ask in plain speech, get answers in plain speech, refine on the fly. Push-to-talk only — no wake-word, no always-on mic, no exceptions. Hands-free intelligence when you want it, silence when you don't.
- Press, speak, release — the mic only listens while you're holding it.
- Spoken responses you can interrupt or dismiss without lifting a finger.
- Multilingual: speak in any language you've taken notes in.
- Goes further than dictation — two-way conversation with your agent.
Manifesto
We refused to pick.
Every tool you use today asks you to give up something — ownership, awareness, or memory. Cloud notebooks hold your thoughts on someone else's servers. Local editors stay silent — they store, but they don't think. Chat AIs forget you the second the tab closes. One way or another, you pay.
So we built one that doesn't make you choose. Your files live on your disk, in a folder you chose, in a format you can read without us. A real graph tracks every relationship between your ideas. Intelligence runs on your machine and gets sharper the more you use it. Cloud models are available — when you ask, with your key.
No relay servers. No always-on microphone. No telemetry pinging home. Privacy is not a feature. It's the floor.
