Six summarizers, what each one is built for, and what it costs, checked on each official site.
Published September 30, 2026 · Updated September 30, 2026 · 11 min read
Choosing the best AI video summarizer is mostly a question of video length and platform. A tool built for a two-hour lecture on YouTube is overkill for a 40-second TikTok, and most YouTube summarizers cannot open a TikTok link at all. Meeting tools are different again: they summarize a call you took part in, not a video someone posted.
We compared six summarizers by what they are built for, what they return, where they work and what they cost. Every fact below comes from each tool's own website, opened on September 30, 2026. ViralDrop is our product; we put it first for short-form video, and its card says only what it does.
Paste a link, get the transcript, then add a summary with its key points.
| Tool | Best for | What you get | Works on | Price (checked Sep 30, 2026) |
|---|---|---|---|---|
| ViralDrop | short-form videos | gist, key points, full transcript, viral breakdown | TikTok, Instagram Reels, YouTube and Shorts | 1 credit per started 30 min, plus the transcript |
| NoteGPT | long YouTube videos and playlists | summaries, mind maps, transcripts | YouTube, audio, files, web pages | free plan; Pro from $108 a year |
| Glasp | summaries beside the YouTube player | timestamped summary and transcript | YouTube, articles, PDFs | free |
| Eightify | key ideas from long YouTube videos | timestamped summary, comment overview | YouTube, in Chrome and mobile apps | see its site |
| Gemini | asking questions about a YouTube video | a chat answer | YouTube | part of the Gemini app |
| Tactiq | meeting summaries | transcripts and AI notes | Google Meet, Zoom, Microsoft Teams | free plan; Pro $8/user/mo, billed yearly |

We did not score these tools on accuracy, because there is no fair way to measure it across videos, languages and lengths, and we will not publish a number we cannot back up. Instead we compared what each one says it does, on its own pages:
A summary is only as good as the transcript under it, so tools that transcribe the speech themselves work on videos without captions, while tools that rely on YouTube's captions depend on them being there. If a summary matters, check its key points against the transcript or the timestamp before you quote it.
Before comparing tools, it helps to know what a useful summary looks like. Four parts separate one you can act on from a paragraph you skim and forget:
Watch for summaries that add things the speaker never said, or that smooth a hedged claim into a confident one. That happens with every AI tool from time to time, which is why the transcript and the timestamps matter more than the polish of the summary itself.
A summary of a two-hour podcast saves you two hours. A summary of a 40-second TikTok saves you 40 seconds, so for short videos the value lies somewhere else.
For long videos, the job is compression: find the three ideas worth your time and the minute where each one starts. Tools built for YouTube, such as NoteGPT, Eightify and Glasp, are designed around that, with timestamps, chapters and playlist support.
For short videos, the job is usually research at scale. A marketer looking at twenty competitor Reels does not need each one compressed; they need the message of each in one line, so they can see which topics and angles keep appearing. They also want to know how each video was built, because in short-form the structure is often the reason it worked. That is why ViralDrop pairs its summary with a breakdown of the hook, structure and call to action.
Best for: summarizing TikToks, Reels and Shorts, and seeing why they went viral.
Paste a TikTok, Instagram Reel, YouTube video or Short. ViralDrop transcribes the speech, and a summary adds a two-sentence gist and five to eight key points above the full transcript. For videos longer than ten minutes, the key points carry timestamps. The summary is written in the language of your ViralDrop interface, whatever language the video is in. From the same video you can run a full analysis of its key frames, on-screen text, hook, body and call to action, which is the part a plain summary leaves out: how the video was built.
Best for: students and researchers working through long YouTube videos.
NoteGPT summarizes YouTube videos and playlists from a link, and says it can batch up to 20 videos at once and summarize videos without subtitles up to 150 minutes long. Beyond video it handles audio, files and web pages, with mind maps, translation and an AI chat.
Best for: summarizing YouTube videos without leaving YouTube.
Glasp's browser extension for Chrome, Safari, Edge and Firefox puts a summary and the full transcript next to the video, and its web page summarizes a pasted link without installing anything. You choose ChatGPT, Claude, Gemini or Mistral, the summary length and the number of key points, and each point has a timestamp you can click. The same extension summarizes articles and PDFs, and highlights can be exported to Notion, Obsidian and other note apps.
Best for: deciding whether a long video is worth watching.
Eightify extracts key ideas from YouTube videos inside YouTube, with timestamped summaries for jumping to a topic and an overview of the top comments. It runs as a Chrome extension and as iOS and Android apps.
Best for: a quick answer about a YouTube video inside a chat you already use.
Google's help pages say Gemini Apps can find YouTube videos, playlists and channels and help you understand what a video is about, using public information from YouTube. You need to be signed in and keep Activity turned on.
Best for: summaries of calls in Google Meet, Zoom and Microsoft Teams.
Tactiq transcribes meetings through a Chrome extension or a Mac app and writes AI summaries, action items and follow-up emails. It also has a YouTube transcript tool, but its plans are built around meetings.
A summary tells you what a video says. An analysis shows how it was built.
The three outputs answer different questions, and choosing the right one saves credits and time.
| You want to know… | Use | What you get |
|---|---|---|
| what a video says, fast | a summary | a gist and key points |
| exactly what was said, word for word | a transcript | the full text, with or without timestamps |
| why a video kept people watching | an analysis | hook, body, CTA, key frames, on-screen text |
| how to make your own version | a rewrite | a new script on the same structure |
Most people start with a summary, go to the transcript when they need a quote, and use an analysis when they want to copy what worked rather than what was said.
Students and researchers use them to decide which lectures and talks deserve a full watch, and to turn the ones they do watch into notes. Long-video tools with timestamps and playlist support suit this best.
Marketers and social media managers use them to keep up with competitors and trends without watching every video in full. For them, the platforms matter: most competitor content lives on TikTok, Reels and Shorts, where many YouTube-only tools cannot follow.
Creators use them to research a topic before filming, and to turn their own long videos into posts, captions and newsletters. A transcript plus a summary of your own video is often the fastest first draft of everything that goes around it.
The AI video summarizer page opens the tool with Summary already switched on; there are also pages for YouTube videos and TikToks.
Browser extensions and meeting bots see more than the video. An extension that works on every page can usually read every page you open, and a meeting tool records what everyone on the call says. Check the permissions an extension asks for, and tell the other people on a call before a tool transcribes it. Website tools that work from a pasted link see only the link you give them, which makes them the easiest choice when you just need one video summarized.
Several of these tools can be used without paying, but "free" means different things:
| Tool | What the free option gives you |
|---|---|
| Glasp | the extension and its summaries, free |
| NoteGPT | a free plan, with quotas below the paid plans |
| Tactiq | 10 meeting transcripts a month and a small AI allowance |
| ViralDrop | free welcome credits for new accounts, enough for a short summary with its transcript |
| Gemini | available in the Gemini app |
For short social videos the free route is ViralDrop's welcome credits: a 10-minute video costs 2 credits to transcribe and 1 to summarize. For long YouTube videos, Glasp is the simplest free choice.
| If you mostly watch… | Pick |
|---|---|
| TikToks, Reels and Shorts | ViralDrop |
| long YouTube lectures, podcasts and playlists | NoteGPT or Eightify |
| YouTube, and you want it free beside the player | Glasp |
| a single video you want to ask about in a chat | Gemini |
| your own work meetings | Tactiq |
A marketer or creator studying competitors usually needs more than a summary. Knowing that a video "explains three money habits" is useful; knowing that it opens with a bold question, pays off every eight seconds and ends with a save prompt is what lets you make your own. That is the gap ViralDrop's analysis fills. If you only ever summarize long YouTube videos, one of the dedicated YouTube tools above will serve you better, and several of them are free.
It depends on the video. ViralDrop is the best fit for TikToks, Reels and Shorts, NoteGPT and Eightify for long YouTube videos, Glasp for free summaries beside the YouTube player, and Tactiq for meetings.
Yes. Glasp's YouTube extension is free, NoteGPT and Tactiq have free plans, and ViralDrop gives new accounts free welcome credits, which cover the transcript and summary of a short video.
Yes, if the tool can open TikTok links. Most YouTube summarizers cannot. ViralDrop transcribes a public TikTok from its link and summarizes it, and it works the same way for Instagram Reels and YouTube Shorts.
Limits vary by tool and plan. ViralDrop transcribes videos up to 120 minutes and prices the summary per started 30 minutes; NoteGPT lists its own limits for videos with and without subtitles on its pricing page.
