Agentic Session Review

See the exact moment #

Fullstory hands your agent the session itself, as structured data it can search and zoom into.

The Fullstory way
A map first. Then zoom to the moment.

Your agent reads the whole session, finds the moment that broke, and opens that exact frame.

Pour the whole session in, and hope

The agent gets raw video at a frame a second. It spends its tokens on footage and can miss the moment that broke.

playing 8× · 1 fps
?
The same moment, as one blurred frame of 8x video.

Agentic Session Review is how your agent works a session. It reads the component tree behind each frame to name the element, console error, and network call at fault. It can also work through far more sessions than anyone has time to watch.

Step 4Loops

Set it up once. Let it run. #

Four loops inspired by real teams. Each one runs on its own and hands you a decision.

Runs hourly, tighter on the busiest days

Catch the silent failures your error logs miss

Every hour, an agent reads what your users just did and pages you when a flow breaks.

  1. WakesHourly, tightened around the busiest days
  2. ReadsSessions with friction and no logged error
  3. DecidesPage now, re-check, or clear
  4. Hands offPages on-call in Slack, queues the rest
  5. YouFix what paged you, review the rest Monday
Every hour, find sessions with friction but no logged error. Page me on anything new, and queue the rest ranked by users affected.
