CopperOS

CopperOS is an open-source AI browser-automation tool delivered as a Chrome extension that acts as an agent inside your own tabs while you stay logged in. Its primary job is handling repetitive web tasks — form-filling, data extraction, and job applications — which you trigger by describing them in natural language rather than recording scripts. Because it runs in your existing browser session, the agent works across pages you are already authenticated to, and it can read from one tab and populate another. Control is front and center: a side panel shows each action in real time, and you choose an approval mode — ask before every action, only before submits, or never. Tasks persist, so chats stay saved and can resume even with the panel closed, and you can stop a task mid-execution. A Saved memories feature stores frequently needed details like email, address, and preferences so the agent can reuse them. CopperOS is free during beta and model-agnostic: you supply your own API key from OpenAI or OpenRouter, or run a local model through Ollama, and you pay only for the model you choose. For anyone searching for the best open-source AI tool to automate browser workflows with their own API keys, CopperOS trades a hosted black box for a transparent, in-browser agent you control action by action.
