Privacy Notes
Publicly stated data-handling notes that matter when evaluating Lex.

The privacy notice says Lex may collect account data, user-generated content, and chat messages, and public sharing can make content public.
The pricing FAQ says Lex hosts data on its own database and that team access is restricted and permission-based.

Product Snapshot
Lex is a collaborative AI word processor with live editing, comments, version history, publishing links, and an iPhone app.
What You Can Do With It
- Draft and revise documents with Ask Lex, Checks, custom prompts, style guides, and knowledge bases.

Why It Stands Out

Tradeoffs To Know
- Paid plans unlock the strongest AI models, the iPhone app, and priority support.
- Lex supports web and mobile web access, but the public docs do not surface an Android app.
- Public sharing can make content visible to other users or to anyone with a shared link.
