## Key features

- **Ask Lex:** A chat panel for feedback, rewrites and brainstorming on the open document. Highlighting text, or tagging @Lex in a comment, asks about one passage. The AI model can be switched.
- **Checks:** Runs line edits for brevity, grammar, readability and more, shown as highlights in the document. Clicking one shows the suggested edit and the reason for it.
- **Custom prompts and context:** Saved prompts can be reused in Ask Lex and Checks and shared with others. Style guides and knowledge bases give the AI a voice to follow and background to draw on.
- **Versions and Rewind:** Versions are named save points for trying another approach. Rewind is a timeline at the top of a document for scrubbing through past changes and restoring an earlier state.
- **Live collaboration and comments:** A shared link gives edit or view-only access, with co-editing in real time and comment threads. Lex Teams is a paid add-on for unlimited group use of shared folders.
- **Export and API:** Documents export to Word, PDF, Markdown, HTML and LaTeX, and an API can create, list and update documents with a key generated in settings.
