The Fragmentation Crisis

Conversations are scattered across platforms. Important context—decisions, prompts, code, plans—gets lost in closed tabs and endless scrollback.

Copy/paste "memory" is manual, inconsistent, and doesn't compound. Agents without your history are shallow; agents without tools are passive.

The Browser as the Hub

If the browser is where AI conversations happen, then the browser can be the secure, user-controlled bridge that:

  • Collects conversation history automatically from AI chat platforms
  • Normalizes and stores it in EverMemOS
  • Enables agents to retrieve, reason & act
