Onset

Onset is an AI release notes tool that drafts updates from pull requests and publishes them automatically.

Onset is a release notes application designed to help companies communicate product updates to customers. Users can write release notes manually or let an AI agent draft them by changing pull requests and completed tasks. The platform connects to Claude, Cursor, and other MCP clients so users can draft and publish updates directly from their preferred editor. Teams can publish updates to a branded public changelog, embed an in-app widget, and notify subscribers automatically. It includes features like scheduled releases, custom domains, REST API access, and email notifications for growing teams.
