A fixed watchlist of AI and publishing platforms is matched, case-insensitively and on whole words, against the titles of the stories the Coral Wire desk collected over the previous 30 days. Buzz is the count of matching stories: how loudly a name is being discussed on the author news wire, not its usage, market share, revenue or quality. The direction marker is that name’s sentiment balance across those same stories (up = positive exceeds negative by more than 8 points, down = the reverse, flat = neither). It is NOT a change since yesterday. Title matching means a story that discusses a platform without naming it in the headline is not counted.
Buzz is a headline count, so it measures news attention and nothing else. A platform authors use every day but that nobody writes headlines about will rank low, and a platform in the middle of a lawsuit will rank high. The watchlist is fixed and hand-chosen, so a platform not on it scores nothing at all rather than zero mentions.
Coral Wire began storing a dated daily snapshot of this leaderboard on 2026-08-21. Before that date the leaderboard was computed live and never written down, so there is no history to publish and none has been reconstructed. The series therefore begins 2026-08-21 and grows by one row per platform per day.
Today’s table and every stored snapshot are served as JSON at https://coralwire.ai/api/tool-leaderboard.json. No key, no charge.

Coral Wire selects stories by a Claude-graded relevance score and writes each headline and one-line summary with an Anthropic Claude model from the linked source. Story gathering is not AI: it is a fixed set of feeds and dockets. The linked original is always the authority.
