Paste a YouTube URL.
Add any YouTube video to a library. ConceptSeek fetches the transcript automatically, with no manual work and no downloading.
Search inside YouTube videos by concept, not just keywords.
ConceptSeek indexes YouTube transcripts so you can find exact moments, quotes, and timestamps across hours of video, without watching back through the footage.
From a YouTube URL to a searchable transcript in minutes.
No downloading, no scrubbing, no rewatching. Paste a link, then search the ideas inside.
Search by concept.
Type what you are looking for in plain language. ConceptSeek uses both keyword matching and semantic similarity to surface relevant passages, even when the exact words differ.
Open the exact timestamp.
Every result shows the passage and the timestamp. Click to jump directly to that moment in the video, with no scrubbing and no guessing.
Cite with the source attached.
Copy the passage, the timestamp, and the video title into your notes, paper, or workflow. Every result is citable by design.
Reading long-form video, finally.
Interviews, lectures, podcasts, documentary footage. Hours of material become a searchable index of ideas.
Research across interviews and podcasts.
Add hours of interviews or podcast episodes and search across all of them at once. Find what someone said, and how they said it, without watching or listening back.
Study lectures and course videos.
Add lecture recordings and search for how a concept is explained across different sessions. Return to the exact passage when you need to review.
Find exact quotes and references.
When you need a citable quote from a video, search for the idea and open the exact moment. The result is the verbatim passage and timestamp, ready to reference.
Compare positions across sources.
Search across multiple videos on the same topic to see how different speakers frame an argument, what they emphasise, and where they agree or diverge.
Results are the actual transcript, not a summary of it.
Unlike AI tools that paraphrase or summarise, ConceptSeek returns the verbatim passage from the video transcript, with the exact timestamp and source title attached. Every result is directly citable.
The thinking stays with you. ConceptSeek’s job is to find the moments and show you the trail. Interpretation, conclusions, and judgment are yours.
