Brief

Magnitude is a local-first agent introduced by Tom Greenwald that bundles its inference engine so models run entirely on your machine; the project claims 100% offline privacy with no tokens or API keys. It installs via npm, profiles hardware to suggest models, runs in the terminal, supports shell automation and file editing, and adds skills for Office, PDFs, and Chrome.

Why it matters

Tom Greenwald (tweet highlighted by @0xSero on 2026-08-08) introduced Magnitude as an "actually local agent" that bundles the inference engine so models run on your computer; he claims it is 100% private and offline, open source, with no token costs or API keys.

Key details

  • Magnitude runs in your terminal and installs with one command (npm i -g @magnitudedev/cli); it profiles hardware to recommend models with trade-offs between quality, speed, and memory, and can use your shell, edit files, and run scripts.
  • Magnitude supports add-on skills for Excel, PowerPoint, PDFs, and Chrome and is pitched for analyzing sensitive data, managing private notes, reviewing code/logs, searching/organizing files, and building docs/slides; source code on GitHub (github.com/magnitudedev/magn…).

Harness bundled with the inference engine

Introducing Magnitude: your actually local agent
100% private and offline. No token costs, no API keys. Open source.

Today's agents are local. The model isn't. Every prompt, every file, every secret gets sent straight to Anthropic and OpenAI.

Magnitude is built around local models and runs the whole stack itself. The inference engine is part of the agent, so the models run inside it, right on your computer.

It lives in your terminal, and setup is one command. Magnitude profiles your hardware and shows you which models fit, with the trade-offs between quality, speed, and memory. Pick one and start working. No painful config or server to babysit.

Out of the box, it can use your shell, edit files, and run scripts. Add skills and it can work with Excel, PowerPoint, PDFs or Chrome.

Use it for everyday work:
- Analyze sensitive data
- Manage private notes
- Review code and logs
- Search and organize files
- Build docs or slides

npm i -g @magnitudedev/cli
