A summary that helps you find what matters.

A YouTube summary tool for long videos

Use an AI video summarizer to find the main ideas in interviews, lectures and podcasts. Read the key points, then follow available timestamps to check the speaker’s words. Video length affects how much there is to review; focus on one topic when you need a closer look.

A document summarizer for PDFs and research papers

Find a document’s main argument, ask about a section or extract key findings. Use supporting passages to check names, numbers and qualifications. A summary helps you navigate a research paper; it does not replace reviewing its methods and limitations.

Choose the focus of your AI summary

Ask for brief bullet points or a detailed answer to a specific question. State your preferred summary length in the prompt. Short Summary is citation-free; choose a source-linked output when you need evidence. Check the original video content when a claim depends on a chart or demonstration that a video transcript may omit.
