Installing the Chrome Extension

Install Memory Capsule in Chrome and start capturing AI conversations in under two minutes.

Last updated: August 2025

What is Memory Capsule?

Memory Capsule is a Chrome extension that sits quietly in your browser and lets you capture, organize, and search the useful knowledge you generate inside AI conversations. Instead of losing insights to chat history, you save them as structured memories you can recall later.

Chrome Requirements

  • Google Chrome version 114 or later (recommended: latest stable)
  • A Google account to sync extension settings (optional)
  • An active internet connection for cloud sync (offline capture works locally)

Installing from the Chrome Web Store

  1. Visit the Chrome Web Store and search for "Memory Capsule".
  2. Click Add to Chrome on the extension listing.
  3. A permissions dialog will appear — review and click Add extension.
  4. Chrome will download and install the extension automatically.
  5. A confirmation toast will briefly appear in the top-right corner of your browser.

Loading the Extension in Developer Mode

If the extension is not yet published on the Chrome Web Store, you can load it directly from the source repository.

  1. Clone or download the Memory Capsule repository from GitHub.
  2. Open Chrome and navigate to chrome://extensions in your address bar.
  3. Enable Developer mode using the toggle in the top-right corner.
  4. Click Load unpacked.
  5. Select the extension build folder (usually /extension/dist or /build) from the cloned repository.
  6. The Memory Capsule extension will appear in your extensions list.

  4. The Memory Capsule icon will now appear permanently in your toolbar.

Verifying the Installation
