Helpolos is an AI-powered workspace that turns public YouTube videos into useful, searchable knowledge. Users can find videos by topic or paste a YouTube link, then explore the content through transcripts, summaries, chat, mind maps, and quizzes. Its AI summaries highlight main ideas, chapters, and important claims, while timestamped transcripts can be searched, copied, and downloaded. Chat with Video lets users ask focused questions and receive answers grounded in the transcript, with links to relevant moments in the source video. The workspace also helps users move between key points and the original video, making it easier to study, research, or revisit specific ideas without replaying everything.

For developers, Helpolos offers transcript and summarizer APIs, with usage-based API credits for integrating these capabilities into research tools and other products. The service provides 10 free daily credits and $1 in API credit, and users can start without a credit card. By bringing multiple ways to understand video into one workspace, Helpolos aims to make YouTube content clearer and easier to use.
