RoastScribe is a FastAPI‑based web service that receives a product description (text, URL, GitHub repo, or UI screenshot) and returns a single‑sentence summary + a witty, constructive roast written in the voice of a selectable “persona” (e.g., a snarky VC, Chef Gordon Ramsay, or the newly‑added Nigerian Chef Tunde). The output is a strict JSON payload that can be consumed directly by a frontend UI, a CLI, or any other automation.
