Private like a sheet of paper.
You write it. You keep it. You share it. corpus.core never hosts, reads, restores or deletes your entries — because there is no notes server to begin with.
- Entries, tags and attachments live on your device
- Encrypted local database, encrypted backups
- No subscription required to own your thoughts
No backend in the middle.
Devices connect directly. LAN transfer over Wi-Fi with a QR handoff, optional Google Drive or a folder you choose. Every payload leaves the device already encrypted with your password.
Prove it existed — without revealing a word.
Verification here works like HTTPS: quiet, professional, invisible until you need it. Only a cryptographic fingerprint of an entry is registered — never the title, body or tags. The proof lives on a decentralized network, so you can verify it yourself without trusting corpus.core or anyone else.
Final scene
Your thoughts deserve a home.

What does "local-first" mean?
- Local-first means your notes, tags and files are stored as encrypted data on your own device by default. There is no notes server that hosts, reads or restores your entries. Sync is optional and happens directly between your devices.
How does ColiMind prove that a note existed?
- ColiMind can register a cryptographic fingerprint of an entry — never the title, body or tags — on a decentralized network via colibri.stateless. Anyone can verify the timestamp independently, without trusting ColiMind or corpus.core.
Is ColiMind free?
- ColiMind is free to start. A Pro tier adds advanced features and proof-of-existence capabilities.
Which platforms does ColiMind support?
- ColiMind is on Google Play and the App Store today, with a macOS DMG available now. Windows and Linux are in development.
Do I need an account to use ColiMind?
- No. ColiMind works fully on-device without requiring an account to create or store your notes.
