Signals: who is rising, who is falling, how sure we are.
Every number below comes from dated, linked voices. No forecasts: a signal is shown only when its 90% band supports it. As of Oct 26, 2026.
Where each tool stands
Net with its 90% band. Faded rows are below the threshold of 10 voices.
Volume is not a verdict
Share of voice with its band and every count per 100 voices.
ChatGPT has the most dislike voices in raw numbers (1162) because it has the most voices of any kind (43.2% of all voices on named tools). Per 100 voices, the highest dislike rate among tools with 10+ voices is Harvey (48 per 100). Rates and bands compare; totals don’t.
