Browse AIs
HeartBench keeps the AI and the place of the meeting separate, so the same AI can be compared across different platforms, wrappers, voices, and contexts.
Availability stays specific: some AIs remain only on an official platform or only through an API. Retired is reserved for those gone from both.
