Memory Engine – AI-Summarization and Personal Memory Extension

Memory Engine is a Chrome extension designed to enhance how users interact with web content. It allows users to instantly summarize any web page using an LLM and store custom, searchable memories locally in their browser. Unlike traditional note-taking or summarization tools, Memory Engine offers a persistent, intelligent memory system — all without requiring authentication or cloud storage.

What Problem Does It Solve?

Most AI summarization tools or browser extensions:

• Require logins or subscriptions
• Depend on cloud databases, compromising privacy
• Do not allow persistent storage of custom-named summaries
• Lack a quick-access memory panel for recalling saved insights

Memory Engine addresses these limitations by offering:

• Complete local memory storage (via localStorage)
• Custom-named, searchable memory entries
• A lightweight, no-login setup
• One-click summarization and memory creation per tab

How It Works

1. Navigate to any web page you want to summarize.
2. Click the Memory Engine Chrome extension icon.
3. A prompt appears showing a summarized version of the current tab.
4. You are asked to name the memory, which can be anything meaningful (e.g., "Internship Tips", "About Kriti").
5. The summary and name are stored locally in the browser.
6. You can access, search, and read saved memories from the panel that appears in the top-right corner of the browser.

Steps to Use the Extension

1. Clone or download the extension folder.
2. Open Google Chrome and go to chrome://extensions/.
3. Enable Developer Mode (top-right).
4. Click Load unpacked and select the extension folder.
5. Visit any website and click the extension icon to generate a summary.
6. Save the memory when prompted, and retrieve it anytime from the memory panel.

Model Used

Memory Engine uses deepseek-chat-v3-0324:free to generate contextual and concise summaries of web pages. The prompt engineering behind the scenes ensures high-quality outputs by instructing the model to act like ChatGPT’s memory feature.

How Memory is Stored

• All memory entries are stored in window.localStorage.
• Each entry includes a title (user-defined) and the AI-generated summary.
• Data never leaves the user's device.
• No backend or authentication is involved, ensuring complete privacy and control.

Tech Stack

• HTML, CSS, JavaScript
• DeepSeek LLM (via public API)
• Chrome Extensions API
• LocalStorage (for memory persistence)

Future Improvements

• Optional export/import of saved memories
• Dark mode toggle
• Support for multiple LLM providers
• Memory editing and deletion features
