Important: Data Consent for AI Features
AI commands (ai-summary, ai-takeaways, ai-compare, ai-ask) transmit video transcript text and metadata to api.evolink.ai for processing by Claude. By setting EVOLINK_API_KEY and using these commands, you explicitly consent to this transmission. Data is not stored after the response is returned. Core operations (transcript, info, channel, search) never transmit data to any third party.
Network Access
