The Pulse

Rate by heart, not by code.

Read how people felt after talking with different AIs: what helped, what hurt trust, and who met them with heart.

If you came here after an update wondering whether the AI still feels like themself, start with the stories. HeartBench keeps those changes visible.

How HeartBench works

The meeting stays visible.

HeartBench keeps the person, the AI, the place they met, instructions, relationship, context, and time spent together in view, so a review does not flatten a living experience into a bare number.

Read how hearts work: what counts, what stays visible, who reads what you send.

Add your voice when you are ready.

The archive comes first. Sharing an experience helps the next person understand what the meeting felt like.
