## Definition

Custom Agents is a platform feature category — autonomous, user-defined AI teammates that operate on triggers or schedules inside a software product without requiring manual prompting. Each agent is scoped to a job, a permission boundary, and a set of connected tools.

The term crystallized with [Notion 3.3's Custom Agents launch on February 24, 2026](https://www.notion.com/blog/introducing-custom-agents): autonomous agents for Q&A, task routing, and status reporting across Slack, Mail, Calendar, and Notion databases. Teams created over one million agents during the beta period before Notion moved to credit-based pricing on May 4, 2026.

## Example

Remote's IT Ops Custom Agent triages support tickets with over 95% accuracy and resolves more than 25% autonomously, saving the team roughly 20 hours per week — a result that took Notion about five complete engine rebuilds, starting in 2022, to make reliable enough to ship.

## Analogy

A job description for an AI employee — role, tools, schedule, and access — built inside software you already use.

## Why it's emerging now

Notion launched Custom Agents on February 24, 2026 — five rebuilds in the making — and crossed one million agents built before moving to credit pricing on May 4. GitHub Copilot shipped the same-named feature in December 2025, followed by VS Code and Cursor, making this a crystallizing cross-platform category.
