Every AI engineer knows the pain: you log a prompt while debugging, and it lands in your console as one endless escaped line — \n everywhere, JSON crammed inline, system/user/assistant turns all mashed together. Unreadable.
FormatTools fixes exactly that. Paste the mess on the left, get a clean, color-coded conversation on the right — roles split, newlines restored, inline JSON pretty-printed. Works with OpenAI, Claude and other LLM APIs. 100% in your browser — nothing is ever uploaded.
