How this report works
Assistants are ranked by their average across the three tests. Only assistants tested on at least two of them are included.
How to choose
- Before you let it send on its own, check that it replies on the right thread and sounds like you. That is what the Email replies test scores.
- If you work in Notion or Slack, look at Connected apps: the test asks for three tools from one message.
- For a daily briefing, look at Routines: the test checks on-time delivery for a whole week and a change halfway through.
What users say
Last week it told me 'NOT TO OPEN' an email from a friend inviting me to a backyard BBQ—it turned out to be a phishing scam.

Open sourceThe agent, which Meta launched on September 8, booked a Friday date night and made a packing schedule for my upcoming move. It also emailed a friend about a trip next month and made a planning document with places we want to visit.
