macOS App

FeynmanLM is a macOS app for tracking your learning sources and connecting them to AI assistants via MCP.

Requirements

• macOS 14 (Sonoma) or later
• Apple Silicon or Intel Mac

Install

Install from the Mac App Store, or download directly. The direct download is a notarized universal binary that runs on both Apple Silicon and Intel Macs.

First Launch

On first launch, the app opens directly to the Studio tab — the central place where all your sources live.

Full Disk Access

To automatically discover articles from your Safari Reading List, the app needs Full Disk Access:

1. Open System Settings → Privacy & Security → Full Disk Access
2. Toggle FeynmanLM on

Without this, you can still add sources manually by pasting URLs, or from Chrome/Brave reading lists (which don't require special permissions).

MCP Server

The app includes a built-in MCP server that lets Claude, ChatGPT, or Gemini access your sources. See Setup MCP Server for details.

The MCP server auto-starts when the app launches. You can check its status and copy connection credentials in Settings → MCP Server.

Key Features

• Studio tab: track and read all your sources in one place
• Source ingestion: automatic discovery from browser reading lists, local PDFs, podcasts
• MCP server: connect Claude or ChatGPT to your knowledge base
• Semantic search: find sources by concept across your entire library
• iCloud sync: all data stored in your private iCloud container
