We are moving past the “Fixed Action” era of AI. You can now give your Custom Agents any tool you can imagine.

Until now, agents were limited by what Notion allowed them to do. By leveraging Workers, we can now build custom tools with Typed I/O and logged execution. This means your agent isn’t just “guessing” how to help; it’s calling specific, hard-coded functions to turn docs into slide decks or query internal databases.

The fascinating part? It’s significantly cheaper and more reliable than pure LLM reasoning. By offloading complex actions to Workers, we gain absolute precision in our workflows. It’s no longer just an “AI assistant” giving you impressions of agency—it’s a programmable employee capable of taking verified actions across your entire business ecosystem. This is the granularity that turns Notion from a notebook into a powerhouse.
