Helpolos vs SonicScribe

Helpolos brings YouTube video analysis, transcripts, and AI chat into one workspace. Provide a public video link or use YouTube search; an analysis can return a summary, timestamped transcript, mind map, and quiz. Chat answers questions from the transcript and links responses to moments in the video. Transcripts can be searched, copied, or downloaded. Developers can use the Transcript API for timestamped plain-text transcripts or the Summarizer API for AI-generated summaries; both require an API key. The Transcript API allows five requests per second per key and returns the video’s original language without translation. A free plan includes 10 credits per day, and credits reset daily at midnight UTC without carrying over. Reopening or reloading an analyzed video uses another credit. Premium plans include 100 daily credits, extended chat context, priority processing, and priority support. Email support is included across plans, with responses within one business day. Helpolos is available on web and through an API.
