Use the editor’s AI panel to rewrite a paragraph or tidy a table. The agent can work on the files in a folder you choose.
The app is free and open source, and AI is optional. Providers set their own fees and limits, and the tools available depend on your connection and the file format.
Connect AI →Get started with the AI agent →Tabs and projects
