Ferrow

Ferrow keeps your vault as a folder of plain Markdown files - no proprietary format, no import step, and any editor can open the same folder. It adds agents that work inside those files under rules you declare, and every change they make is logged and reversible with one command. Bring your own model: an API key you already have, or something local via Ollama. Everything on your own machine is free; the paid tier covers only what runs on our servers. Pre-1.0 and honest about it.
