Can I trust it?
- LGPL-2.1-only. Free to use and change. If you share a changed version of the library itself, you must share those changes under the same licence. Using it privately has no extra obligations.
- Your data: stores no personal data. Rules and dictionaries are files. The server keeps no text after checking it.
- Other services: n-gram data (optional) (optional, free download); Browser extension or LibreOffice add-on (optional, free)
- Reviewed version. Your AI always gets exactly the version we've checked.
- Anything you check is sent to the server you configure. Run your own for private text.
- Do not expose the server to the internet without limits and a reverse proxy.
