We're building the free AI browser agent that runs on your machine.
Cereal started in Rotterdam as an internal tool to run scraping scripts reliably without babysitting them. Other people wanted it too, so we opened it up and added a marketplace of ready-made scripts. Next comes the AI browser agent: describe a goal, and it drives Chrome on your machine with your own model and key.
Your model.
Your key.
01 / your machine, your model, your key
Automating a website shouldn't need a VPS, a cron job or a subscription. The agent works in a Chrome window you can watch, on your own computer, with the model you pick: Anthropic, Gemini, OpenAI, OpenRouter, or a local one like Ollama. Your key never reaches Cereal; the agent's model calls go only to the model provider you pick, or stay on your machine with a local model.
02 / learn once, then repeat
The first run, the model works out the steps. After that, Repeat replays what it learned without calling the model, so routine checks cost nothing. If the site changes, the model picks up where the replay stopped.
03 / ready-made scripts
Not every job needs a model. 100+ ready-made scripts run in Cereal today. Script authors build them with the Kotlin SDK and keep 70% of what they earn, which keeps the shelf stocked and the work rewarded.
How we build.
Your key, your provider
The agent's model calls go straight from your computer to the provider you pick, never through us. With Share diagnostics on (the default), the agent reports how each run went, and, when a check fails or you report it, what it saw on the pages, masked and deleted after 30 days. You can turn it off in Settings › Privacy. We'd rather not hold data we don't need.
Developers are users too
The SDK is a product. We design for people writing scripts with the same care as people running them.
Show, don't market
We'd rather ship a working example than promise one. The README is honest, the changelog is current, the Discord is open.
Plain text, plain prose
Em-dashes, lowercase nav, monospace where it earns its seat. No corporate filler — no "revolutionize your workflow."
