Encrypted local notebook · public beta
Onnoir is a private desktop library for work that should stay yours.
Write notes, keep source files nearby, search your local library, and leave with Markdown or encrypted backups. No account is required for the beta.
— macOS and Windows beta; verify a backup before updating
Local vault
Your notebook library lives on your device and opens with your passphrase and recovery key.
Connected research
Pages, source files, canvases, threads, search, and Atlas stay connected without turning private work into a feed.
Readable exit
Export Markdown for open copies, and keep encrypted .onbk backups when you need exact recovery.
Write
A page can hold the whole thought.
Write prose alongside code, math, Mermaid diagrams, tables, callouts, local files, images, and canvas references, without splitting the work across separate tools.
Organize
Keep research readable as it grows.
Use notebooks, threads, collections, search, Today capture, and Cabinet media to keep source material close without turning private work into a feed.
Connect
See the shape of a project.
Atlas maps notebooks, pages, threads, media, canvases, and filed notes so important relationships stay visible while the library gets larger.
Protect
Keep a readable copy and a recovery path.
Export Markdown when you want open files. Create encrypted .onbk backups for exact recovery, and verify them before beta updates.
Trust model
Privacy is a product decision, not a tagline.
Onnoir stores your library locally in an encrypted vault. Anonymous diagnostics are optional and never include note content, capture text, search queries, file names, media names, local paths, passphrases, recovery keys, or vault identifiers.
Encrypted at rest
The desktop vault uses a passphrase-derived key and a recovery key flow for local access.
No sign-in required
Open the beta into a local library. Optional online services, if added, will be opt-in.
Portable by default
Export Markdown for readable copies, and keep encrypted .onbk backups for exact recovery.
Optional diagnostics
Anonymous diagnostics are off unless you opt in, and never include note content, capture text, search queries, file names, media names, local paths, passphrases, recovery keys, or vault identifiers.
