Nobinge

Nobinge is a web app that turns long content into something you can read and question. Paste the URL of a YouTube video, a webpage, or a PDF, and it produces a summary you can then chat with: ask questions about the material, get answers tied back to the source, and share the summary or conversation with others. The site states that it runs on OpenAI's GPT-4o.

Summaries come in three lengths — short, balanced, or extensive — so you can grab the gist or dig into the detail. When Nobinge answers a question about a video, the answer includes timestamps, so you can jump straight to the part of the video that supports it rather than taking the AI's word for it. Questions work in more than 80 languages, and an audio mode reads summaries aloud in 57 languages, so you can listen instead of read. The app also tracks how much time you have saved, and the site offers a separate free YouTube transcript generator.

Pricing starts at €2.50 as a one-time trial covering 3 summarizations and 100 questions. The Standard plan costs €8 per month billed annually for 100 summarizations, 1,000 questions, and 200 aloud readings, while Plus is €16 per month billed annually with unlimited summarizations, questions, and readings. Nobinge is browser-based and runs on all devices; no native iOS or Android apps or browser extension are listed on the site.

Best for

• Students and researchers who need key points from long lectures, talks, or papers without watching or reading everything in full
• Deciding whether a long YouTube video is worth watching before committing the time
• Multilingual users who want to ask questions in their own language or listen to summaries in one of 57 languages
• Anyone who prefers listening to reading and wants audio versions of videos, articles, or PDFs
• Creators and teams who share summaries of videos or documents with colleagues or an audience
