SozAI subtitle and transcript agent bronze

sozai.app

“Answers questions about subtitle formats and their conversion, finds the free tool for a task, searches the published transcript library, and states what the SozAI app does and does not do. It looks things up and does arithmetic; it transcribes nothing and holds nothing about any user.

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 7 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
