AI voice over generator: narrate any script inside ChatGPT and Claude

Creative Claw generates voiceovers inside ChatGPT, Claude or Codex: write or paste the script, pick a voice from the ElevenLabs, Cartesia, Google and MiniMax libraries or your own cloned voice, and get an MP3 with word timings for captions, then lay it over your video in the same chat. ElevenLabs v4 costs 20 credits per 1,000 characters, so a 15-second voiceover is about 4 credits ($0.04). No subscription.
