Comment Mode - Generate short, context-aware comments on feed posts, company pages, profile feeds, and activity pages. Compact AI toolbar appears right in the comment box.

DM Reply Mode - AI reads the last few messages in your conversation and generates a natural reply. Works in messaging pages and conversation overlays.
