Local-first notes
Onnoir is built around a desktop library first. You can write, organize, search, attach source material, export readable copies, and keep recoverable backups without starting from an online account.
Local workspace
Onnoir keeps notebook content in a local encrypted vault. That makes it a practical fit for private drafts, client notes, internal research, and source material you do not want to place in a web-first workspace.
Daily work
Pages can hold prose, tasks, tables, callouts, code, math, Mermaid diagrams, images, files, and canvas references. The goal is to keep longer sessions fluid without spreading the work across unrelated tools.
Exit path
Markdown export gives you readable files outside Onnoir. Encrypted .onbk backups preserve the local library for restore. Both matter when the work should remain portable.
Fit
Start writing without creating a hosted notebook account.
Notebook content starts on your device, protected by your passphrase and recovery material.
Use notebooks, threads, collections, Today capture, Atlas, and indexed document text to keep projects readable as they grow.
Questions
No. The website, downloads, update checks, and optional future services are separate from your local notebook content. The notebook workflow itself does not require a hosted account.
Yes. Onnoir supports readable Markdown export and encrypted .onbk backups for exact recovery.
