Maximem Vity is memory for the AI apps you already use. Where Maximem Synap is developer infrastructure you build into your own agent, Vity is for end users: install a plugin or browser extension into a host product and your AI context syncs across platforms automatically, so you never have to re-explain yourself.
Building your own agent? You want Maximem Synap and its SDK integrations. Vity is for adding memory to the apps you use day to day.

​
What Vity does

  • Cross-platform memory: your facts, preferences, and history follow you across ChatGPT, Claude, Gemini, Manus, Perplexity, OpenClaw, and more.
  • Automatic recall and capture: relevant context is injected before each turn and new context is saved after, with no manual steps.
  • You own your data: memory lives in a private cloud vault with encryption at rest. You can recall, forget, or delete anything at any time.

​
Available for

OpenClaw

Memory plugin for OpenClaw. Syncs context across OpenClaw, ChatGPT, Claude, Gemini, Manus, and more.

Hermes Agent

Persistent, cross-session semantic memory for the Hermes Agent. Recalls and captures automatically each turn.
A Maximem Vity browser extension brings the same memory to web-based LLMs such as ChatGPT, Claude, Gemini, and Perplexity. More host apps are rolling out.

Vity vs Synap

If you are building your own agent, see Synap integrations. If you want memory inside an app you already use, install the Vity plugin for it.
