Get the substance of any YouTube video without watching it. AI reads the full transcript and returns summaries at three depths, the key points, and chapters you can click straight into.
A one-line gist when you only need to know whether to watch, a medium summary for the argument, and a detailed version of 1,000 to 1,500 words when you need the substance.
Five to eight key points pulled from the video, plus any concrete action items, so a long talk becomes something you can actually act on.
Four to eight timestamped chapters mapping the structure of the video. Click a chapter to jump straight to that section instead of scrubbing.
Three to five fact-check items flag claims worth verifying, and topic detection tells you what the video actually covers versus what the title promises.
Most summarizers give you one paragraph and hope it fits. It rarely does, because the reason you are summarizing changes what you need. Deciding whether a two-hour interview is worth your evening is a different task from writing notes on it, which is different again from pulling out the part that matters for a piece of work.
Exactum returns all three at once. The short summary answers the triage question. The medium summary carries the actual argument and how the speaker gets there. The detailed summary runs 1,000 to 1,500 words and is close to a substitute for watching — long enough to hold nuance, caveats, and the order things were said in.
Because all three come from the same pass over the full transcript, they stay consistent with each other. You are not getting three different readings of the video, just three resolutions of the same one.
The risk with any AI summary is that you cannot tell what it left out or quietly invented. Exactum keeps the full transcript alongside the summary, with timestamps, so every claim is one click from its source. If a summary line looks wrong or surprising, you can jump to the moment in the video and see for yourself.
The fact-check pass makes this explicit by surfacing three to five claims from the video that are worth verifying independently. It does not adjudicate them — it flags them, which is the honest thing for a tool to do with a claim it cannot check.
You can also interrogate the transcript directly. Ask what the speaker said about a particular topic and get an answer grounded in the text rather than a general impression. For longer research projects you can ask questions across every transcript you have saved.
Summarizing is metered in hours of video analyzed per month, not per video, so a short clip costs far less of your allowance than a three-hour podcast. The Free plan includes one hour of analysis per month. Basic includes 300 hours at $6.99 per month, Starter 1,000 hours, Creator 3,000, and Studio 8,000. Yearly plans add twenty percent.
Pulling the raw transcript without AI analysis is metered separately and more generously: five extractions per month on Free, and unlimited on every paid plan. If you only want the text, that is the cheaper path.
Re-running the analysis on a transcript you already saved does not count as a new analysis, so refining or revisiting a summary does not cost you a second time.
Turn recorded lectures into structured notes with chapters that match the syllabus, then check anything ambiguous against the source.
Triage a long list of conference talks and interviews quickly, and keep detailed summaries of the ones that matter.
Keep up with earnings calls, keynotes, and industry talks without giving each one a full hour of attention.
See how a competitor structured a video, and turn your own long-form content into show notes and posts.
Get the shape of a public statement or press conference fast, with the full transcript underneath for exact quotes.
Decide in thirty seconds whether a video deserves your hour, instead of finding out forty minutes in.
Add the free Exactum extension to Chrome. No account is needed to try it on your first videos.
Go to any public YouTube video that has captions. The extension recognises it automatically.
One click reads the transcript and runs the AI over it. Summaries, key points, and chapters come back in seconds.
Keep the summary, export it, or ask the transcript follow-up questions to dig into a specific claim.
Install the free Exactum Chrome extension, open any YouTube video with captions, and click to analyze. The AI reads the full transcript and returns short, medium, and detailed summaries, key points, and timestamped chapters in seconds.
The Free plan includes one hour of video analysis per month. Paid plans raise that considerably: 300 hours on Basic at $6.99 per month, 1,000 on Starter, 3,000 on Creator, and 8,000 on Studio. Yearly plans add twenty percent.
There is no per-video length limit for YouTube analysis. Because analysis is metered by total hours per month rather than per video, a three-hour podcast simply uses more of your monthly allowance than a short clip.
Summaries are generated from the video’s full transcript, and the transcript stays available beside them with timestamps, so you can verify any line against the source. A fact-check pass also flags three to five claims worth checking independently.
Yes. Transcription covers 47 languages with automatic detection. On the Starter plan and above you can also translate the transcript and its analysis into any of 79 languages.
Yes. Ask Transcript answers questions using the transcript itself rather than general knowledge, so answers stay grounded in what was actually said. It is available on the Basic plan and above.
Yes, as TXT, PDF, DOCX, SRT, VTT, Markdown, or JSON. Notion and Obsidian export are available on Creator and above.
No. The extension reads the existing caption track in your browser. Nothing is downloaded or uploaded, which is why it finishes in seconds.
