Nod
Open-source AI agent that runs errands on real sites and asks before acting for you
Nod is an open-source (Apache 2.0) personal agent that runs on your own Mac or Windows machine and does errands like chasing invoices, prepping call briefs, or cancelling trials on real websites, asking before it takes any action that speaks or acts for you. In their own tests — 226 errands run three times each — it finished 98% of them, recalled facts from earlier sessions on 93.2% of 500 questions (LongMemEval-S), and resisted all 216 tried prompt-injection attacks from 108 published attack emails (WhisperBench). It's free and brings your own model: ChatGPT Plus/Pro or any AI API key.
What holds up
- +Open source under Apache 2.0 — free, and you can read exactly what it does
- +0 of 216 prompt-injection attacks succeeded in their own published WhisperBench test
- +Stores call briefs and notes on the machine it runs on, not on their servers
- +Every remembered fact is visible and editable, with the message it came from
Mind the limits
- −Windows support is still a preview, not a finished release
- −One owner per Nod today — a team can't yet share a single agent
- −You still pay for the model separately — Nod doesn't include ChatGPT or API costs
