Download OnnoirPublic beta · v0.1.0-beta.1

— macOS and Windows beta; verify a backup before updating

The shelf keeps notebooks, threads, recent work, and local context in one private workspace.

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 is designed around local ownership first: no account gate, no silent sync, and export paths you can use without asking permission.

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.

Separate metrics

The website uses aggregate page and download metrics. Optional app diagnostics are controlled separately inside the desktop beta.
