crosswalk

crosswalk is an AI newsletter reader and inbox built into Claude, ChatGPT, and other supported agents.

Crosswalk is an AI newsletter reader and inbox built into Claude, ChatGPT, and multiple other AI agents. Users subscribe with a dedicated email address to read, summarize, or search newsletters directly through their connected agent. The platform includes an inbox, groups, calendar, and notes, letting agents read curated sources and personal feeds. It supports private user feeds that act as a persistent server-side configuration, duo crosswalks for sharing with friends, public feeds, and group crosswalks for teams or communities. Connecting is user-initiated via an MCP server URL, and it supports agents like Claude, ChatGPT, Cursor, and others.
