Transcribes up to 5 call recordings and scores each with AI

Transcribes up to 5 call recordings and scores each with AI: greeting, needs found, booking or sale made, objections handled, missed opportunities, sentiment and a coaching summary, plus your own questions. Priced per minute allowance: files x maxMinutesPerFile (default 5, at most 10) x $0.04. Runs nerolabs/call-score; can take a minute or two.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
