Notion

The pitch now centres on agents rather than pages. Alongside the shared workspace where teams keep documents and project knowledge, Notion offers Custom Agents that carry out work on a schedule or in response to something happening — the site's examples include triaging product feedback, handling support tickets inside Slack, reacting to security alerts and putting together weekly reports.

Search runs across connected apps rather than just Notion content, and answers come back with citations pointing at the source, so a claim can be traced to the document it came from. The stated goal is a single system of record that the AI can actually read.

There is a free option to sign up with, and demos are available for teams. Notion says 98% of the Forbes Cloud 100 use it.
