Live draft meter

Compose box scores as you type. Questions and substantive length push score up. Bait phrasing, hashtag spam, and ALL CAPS get flagged before you post.

Reply-aware mode

Reply drafts scored as replies, including out-of-network factors, so you do not optimize a reply like it is an original For You post.

Mutual / OON toggles

See how mutual-follow boosts change reply weight from 5 to 20, and how out-of-network rescoring reshapes the same draft.
