Grammarly: Checks and rewrites English text in any window: email, chat, documents.

Lexis+ AI: AI legal research on the LexisNexis database with citations to US and UK law.

The extension reads everything you type in the browser, including form fields: decide in your corporate policy whether it is allowed on work computers
Rewriting a sentence changes its legal meaning: in English contracts and claims, accept only spelling fixes
For text in other languages the service offers almost no suggestions; use LanguageTool for that

Jurisdictions outside its coverage have no legislation or case law in the database: search them separately
Check case citations against the full text of the decision before using them in a position
Access is tied to the subscription's jurisdiction: the law of another country may be unavailable
