Memdex, a Chrome extension, offers a freemium model, giving users a way to combat ‘AI amnesia’ across their various AI interactions. The starter tier allows for manual recording of conversations and access to your **10 most recent chats**. For those needing more, paid options begin at **$7 per month**, billed annually, releasing features like auto-recording and unlimited conversation access. what it does is provide a shared, persistent memory for AI tools, addressing the common issue where AI models often lack context from previous discussions.

## Getting Started with Memdex

Installing Memdex is straightforward; it’s a Chrome extension, so you’ll just add it from the Chrome Web Store. Once installed, it doesn’t require complex setup. Memdex immediately begins capturing and saving chat history from supported AI tools like ChatGPT, Claude, and Gemini. This happens automatically in the paid tier, while the unpaid version requires manual recording. It’s quite simple to get going.

### Your First Context Injection

Here’s how it works in practice: Imagine you’re starting a new conversation with ChatGPT. As you type your prompt, Memdex actively monitors your input. It’s looking for keywords that match discussions you’ve had before, even if those were on Claude or Gemini. When it finds relevant past context, it highlights those keywords. You’ll then see an option to inject this historical information directly into your current chat with a single click. This eliminates the need for manual copy-pasting or re-explaining background details, which can be a real time-saver.

## Unifying AI Memory Across Platforms

Memdex’s core function is to create a reusable local memory for AI conversations. It automatically captures and saves chat history from major AI tools. This data stays **100% local and encrypted** on your device, stored using IndexedDB. When you’re typing a new prompt, Memdex highlights relevant keywords from past discussions, allowing for one-click injection of this historical context into the current session. It’s a practical solution for maintaining conversation continuity and ensuring ongoing projects don’t lose momentum due to forgotten details.

### Supported AI Tools and Browsers

Memdex offers native integration with ChatGPT, Claude, and Gemini. In practice, it works directly within those interfaces. For other AI tools, it’s not a dead end; Memdex can compact a conversation into a portable summary. You can then paste this summary wherever you need it. The extension itself is compatible with any Chromium-based browser, including Chrome, Edge, and Brave. That’s a pretty broad reach for users.

## Data Privacy and Known Limitations

Memdex places a strong emphasis on data privacy. Your data remains **100% local and encrypted** on your device; it’s never uploaded or used for training AI models. The developer, NOWGIC LTD, has stated its commitment to complying with EU laws, implying GDPR adherence, though specific certifications aren’t listed. This local storage approach means your data isn’t synced by default across devices, which could be a limitation for users working from multiple machines. There’s also the potential for memory overload if you accumulate vast amounts of local data, though the specifics of this aren’t detailed.

Another point to consider is browser support. While it works on Chromium-based browsers, it doesn’t support others. Users might also experience some latency during processing, and for AI tools not natively integrated, you’ll need to manually extract context. It’s worth noting that the Chrome Web Store listing currently shows no user ratings, so we can’t draw conclusions from user reviews there.

What happens when you need to share a specific AI conversation’s context with a colleague who doesn’t use Memdex, or perhaps a different browser entirely? It’s a question that current local-first memory solutions don’t fully answer yet.
