Memex
Memex is a browser extension knowledge base and personal information manager designed for indexing, annotating, and organizing web content into a searchable personal archive. It functions as a web annotation tool that allows users to add highlights and notes directly to webpages and PDFs.
The system features an AI-powered document summarizer that generates concise answers and summaries based on indexed materials using cited references. It includes an encrypted content synchronizer that uses end-to-end encryption to mirror archives and annotations across multiple devices.
The platform provides capabilities for full-text search and filtered content retrieval across bookmarked sites and documents. It covers content management through browser tab organization and automated tagging, as well as data persistence via local-first storage and cloud backups.
The project provides standardized APIs to connect saved knowledge to external tools and AI agents for interoperable information sharing.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
