First launch

Windows protected your PC

Nodio is signed with a valid certificate from Obelisk Systems — you’ll see that name as the publisher in the dialog. Windows SmartScreen may still show a warning for newly released apps until enough downloads have built up reputation. This isn’t an error or a sign of malware.


What to do: click “More info”, confirm the publisher reads Obelisk Systems, then “Run anyway”.

 

The warning clears over time on its own. If you’d rather check first, scan the file or check the VirusTotal report.

Create or open a project

Each project is one .db file on your disk. Pick a folder you control — nothing is uploaded.

Start from a template

GDD, Zettelkasten or Sprint starter projects give you a credible board in seconds.

Connect AI / MCP (optional)

Point Cursor or Claude Desktop at 127.0.0.1:7421 to use your graph from your IDE.

Backups are automatic

Nodio keeps automatic backups; export to ZIP or Markdown any time.
