Nod by n8n

Nod is an open source personal agent that gets real-world errands done in your apps and on real websites, using its own private computer on your Mac or Windows PC. Key capabilities: • Chases overdue invoices and sends follow-ups • Writes a one-page brief for every upcoming call • Cancels free trials and subscriptions on real websites • Works across your apps, browser, and desktop • Asks permission before acting on anything you didn't request • Runs on the model provider you choose, including ChatGPT Plus or Pro or your own API key Nod takes orders only from you. Each morning it reads your email threads, calendar, and the latest client news, then stores a prepared brief on the machine or server that runs it. Only the information needed for a given task is sent to your chosen model service, so you keep control of what leaves your computer. Because Nod works through the same apps and websites you use, it handles tedious admin without requiring you to build integrations or write code. Benchmarks show high task completion across test errands, strong recall of past conversations, and no false memories planted by malicious emails. Nod is free under the Apache 2.0 license, and the code is publicly available to inspect and modify. Nod is built for freelancers, founders, consultants, and busy professionals who spend hours on invoices, scheduling, meeting prep, and subscription management. It is available as a Windows 11 preview and for macOS 14 or later, and it is a good fit for anyone who wants a personal assistant that runs on their own hardware.
