Helpolos vs yTeaser

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.

yTeaser takes a YouTube link and returns an AI summary with three extracted takeaways, each under 100 characters. It detects the video’s language, summarizes in that language, and translates non-English videos into English. Optional sentiment analysis grades reactions in top comments from A+ to F. The web app and Chrome extension provide access; the extension adds a summary button to YouTube thumbnails and shows results inline. A REST API offers video summarization and English translation endpoints, rate limited to 20 and 30 requests per minute respectively. The Slack bot detects YouTube links and replies in message threads, although the site says it is awaiting Slack review and approval. The free plan costs nothing and allows 10 summaries per day without an account. Pro costs $1.99 a month or $9.90 a year, with 50 summaries per day and priority support. yTeaser accepts YouTube links, not uploads. Summaries may fail for private, age-restricted, removed, or very short videos.
