Ask about any part of an answer, without losing the thread.

How it works
- Side chats. Each block of a reply can hold its own persistent conversation, anchored to that exact passage.
- Made for STEM. Equations render properly and can be quoted as the formula itself, and you can type your own in an equation box.
- Your work stays yours. Every account runs in its own private workspace.
