# Maximem Vity

> Maximem Vity gives the AI apps you already use a shared, persistent memory. Install a plugin or browser extension and your context follows you across ChatGPT, Claude, Gemini, OpenClaw, and more, with no code.

Maximem Vity is memory for the AI apps you already use. Where [Maximem Synap](/getting-started/overview) 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.

<Note>
  Building your own agent? You want [Maximem Synap](/getting-started/overview) and its [SDK integrations](/integrations/overview). Vity is for adding memory to the apps you use day to day.
</Note>

## 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.
