Introducing the OpenMemory Chrome Extension

If you're like most people using AI today, you probably switch tools based on the task. You might turn to ChatGPT to brainstorm ideas or draft content, use Perplexity to do research, rely on Claude to help write or review code, and check in with Gemini for quick summaries or contextual answers. Each tool has its strengths, but none of them remember the context that you have already given to the others. The context lost between tools is exactly what we’re solving.

At Mem0, our mission is to build the memory layer for AI agents - a universal, portable memory infrastructure that works across tools, assistants, and environments.

Today, we're excited to introduce the OpenMemory Chrome Extension - a lightweight, client-side memory layer that brings persistent, user-controlled memory to browser-based AI tools like ChatGPT, Claude, Perplexity, Grok, Gemini.

What Is the OpenMemory Chrome Extension?

The OpenMemory Chrome Extension is a local memory layer for browser-based AI assistants. It captures relevant context from your conversations, stores it in a structured memory format, and lets you reuse it across sessions and tools.

It works entirely in the browser, no server needed, and is fully integrated with the OpenMemory dashboard for visibility and control.

How It Works

Once installed, OpenMemory integrates directly into ChatGPT, Claude, Perplexity, Grok and Gemini. It automatically detects key facts from your conversations - like “lives in New York,” “is vegetarian,” or “is preparing for a product launch”, and saves them as memories. These can then be reused across different tools without you lifting a finger.

• OpenMemory analyzes the prompts sent by users, extracts information, and when it finds something relevant, it saves the information as memory in a structured format.

• When a user is chatting, OpenMemory automatically detects and applies relevant memory, and enhances your prompts behind the scenes. This helps the assistant give more relevant responses without you having to restate anything.

• You can also import your existing ChatGPT memory with one click. Go to Settings > Personalization > Manage Memories > Sync memories.

All of this is managed through a simple, intuitive dashboard where you can view, search, edit, or delete your stored memories at any time.

Supported Tools

The extension currently works with:

• Claude (Anthropic): Activate memory manually with a button or Ctrl + M shortcut.

• ChatGPT, Perplexity, Grok, Gemini: Automatically detects and applies relevant memory. OpenMemory quietly enhances your prompts behind the scenes.

What it Enables

With OpenMemory, your AI tools start working together more like a team, sharing the same understanding of who you are and your preferences.

You get:

• A more coherent experience across tools
• Time saved from not retyping the same information
• Personalized results that reflect who you are and what you need
• Full control over your data
• And yes, it’s completely free. No usage caps. No ads. Just better AI, finally made personal.

Use Cases

Some practical examples of OpenMemory:

• Ask ChatGPT to outline the architecture for a new feature, then move to Claude to generate code or write documentation without any repeated context shared.
• Share dietary or travel preferences once and have all tools consider them into travel or meal suggestions later.
• Save project-specific roles or responsibilities (e.g. “leads growth at an early-stage startup”) and have assistants tailor suggestions accordingly.
• Set a preferred tone or writing style, and carry that consistency across assistants.

Conclusion

With the OpenMemory Chrome Extension and OpenMemory MCP, we’re building toward a future where memory isn’t locked into one product or platform, it’s portable, user-controlled, and shared across the tools you already use.

We believe memory should be a first-class layer for AI agents. The tools you choose should work together, and your context should move with you, by default.

This extension is just one step in that direction, but it’s a meaningful one.
