Notion is a cloud-based collaborative workspace platform built around a block-based document model, with a public REST API that allows developers to read and write pages, databases, blocks, and users programmatically. Notion AI is deeply integrated into the product, powering enterprise semantic search across connected tools, AI-generated meeting notes, and custom agent workflows that can be triggered by events or schedules.

Custom Agents in Notion can be configured to perform multi-step automations — such as triaging product feedback, resolving Slack support tickets, or sending weekly reports — without code. The platform also exposes a Connections layer that integrates with third-party apps (Slack, GitHub, Jira, etc.), enabling agents and search to operate across an organization's entire data ecosystem.
