Notion 3.4 added 'Workers for Agents' - AI agents can now run code, query databases, and call external services

The big upgrade since Notion 3.0 Agents. Workers gives the agent a way to actually compute (count won vs lost deals, hit an API, format an output) instead of vibe-summarising. Plus AI Autofill for databases, Skills (saved workflows), and Calendar/Mail/Slack integration. Verdict-relevant if you've been treating Notion as a doc tool only - it now has a real chance of replacing one or two automation/Zapier flows. Custom Agents free to try until 2026-05-03, so this week is the right time to test before pricing settles.
