Notion's April recap: Agents get better, then go paid

Editor's note: Get 3 months of free Notion Business here.

The Custom Agents free beta ended May 3. Notion spent the entire month of April making sure teams would still want them on May 4.

Cheaper agents, more use cases

The biggest April release was Notion 3.4 Part 2, arriving on the 14th with a direct economic argument: Custom Agents now cost 35–50% less to run across the board. Teams using lighter models like Haiku 4.5 or GPT-5.4 Mini got up to 10x fewer credits consumed per task. Notion also shipped AI Autofill, which runs agents directly against database rows, enriching and categorizing data across every entry continuously. That's a new billing surface: every auto-enriched row is an agent run.

By early May, teams had created more than half a million Custom Agents during the beta. That number says something about Notion's conversion approach: get teams dependent on agents during the free window, then offer a price they can defend internally.

The intelligence stack

April added meaningfully to the AI layer underneath those agents. Claude Opus 4.7 landed on April 16, with 3x fewer tool errors and better reliability on multi-step workflows. Notion Agent got calendar access on April 15, letting it find availability and book meetings directly from chat. Mail and Calendar were promoted to a dedicated settings tab on April 17, becoming first-class connectors rather than buried options. Voice input came to desktop early in the month.

None of these were standalone features. Each extended how many hours of the day an agent could be genuinely useful, which is what justifies a recurring credit spend.

Under the hood

The developer changelog ran parallel to the product track. Notion shipped Notion MCP improvements including better search results for private Slack channels, multi-value filters for select properties, and generally available update and delete endpoints for comments. The API is now much closer to parity with the UI, which matters for teams building integrations on top of Custom Agents rather than using them only through chat.

Teams tracking Notion should watch agent billing data as it starts accumulating. Half a million agents created during a free period means a large volume of cancel-or-convert decisions is happening right now.
