9 Best AI Video Summarizers of 2026

NoteGPT is built around the job this list covers. You paste a YouTube link or a playlist, click Generate Summary, and the tool fetches the transcript and returns the key points; the vendor says you can batch summarize up to 20 videos at once on its top plans, and translate subtitles in over 60 languages. The Pro plan, at $9 a month billed yearly or $9.99 month to month, covers YouTube videos with subtitles at any length, videos without subtitles up to 120 minutes, 5 videos at a time and 2 YouTube channels, plus 1,000 basic quotas for transcription, summaries, mind maps and translation. Unlimited at $19.92 a month billed yearly removes the basic quota cap and lifts the no-subtitle limit to 210 minutes. The trade-offs are a small premium credit allowance on Pro, a 1GB cap on uploaded files and a refund window of only 24 hours after the first purchase.

Gemini is the simplest way to summarize a YouTube video if you already have a Google Account. According to Google's Gemini Apps Help, you can ask Gemini to find a video and then ask about it, and the help page uses "Summarize the first video" as its example prompt; it can also find videos, playlists and channels on a topic. The free plan costs nothing, Google AI Plus is $4.99 a month with twice the free usage limits, and Google AI Pro is $19.99 a month with four times the free limits plus 5 TB of storage and a YouTube Premium Lite plan in supported countries. There are conditions: you must be signed in with Keep Activity turned on, the feature is not available in Live chats or in Gemini in Google Messages, and Gemini cannot act on your YouTube account, such as saving a video to a playlist. Summaries arrive as chat replies, so there is no separate library, batch mode or export format like NoteGPT or Recall offer.

Recall treats a video summary as the start of a note rather than a one-off answer. You save a YouTube video, podcast, article or PDF, and Recall produces a concise or detailed summary with timestamps, then files it as a card with smart tags and links it to related cards in a knowledge graph. The Plus plan at $10 a month billed yearly unlocks unlimited AI summaries, chat across everything you have saved or the open web, Listen Mode with custom voices, and quizzes with spaced repetition. The free plan is permanent and saves unlimited content, but only 10 items a month get AI summaries. Max, at $38 a month billed yearly, adds a choice of frontier models and bulk actions on up to 100 items. Recall runs on the web, in four browsers and on iOS and Android, offers a 30-day refund and gives students 20% off by email. It is less suited to people who just want a quick summary and nothing saved.

Mapify summarizes a YouTube video as a mind map instead of a block of text, which helps when a talk covers several linked ideas. The free plan, with no credit card, includes 30 one-time AI credits, 5 YouTube videos and 5 PDFs or documents turned into mind maps, and access to YouTube video transcripts. Basic costs US$5.99 a month billed yearly or US$9.99 monthly and adds 1,000 AI credits a month, YouTube and document summaries, editing, exports to PDF, Markdown or SVG and a slide presentation mode. Pro, at US$11.99 a month billed yearly, adds a more capable model, timestamps for audio and video mind maps, audio and image summaries, Deep Research and AI chat with your content. One subscription covers the web app, the browser extension and apps for iOS, Android, iPadOS and macOS. The main limits are that free credits do not refresh and paid credits do not roll over.

Monica is a general AI assistant, and YouTube video summarization is one row in a long feature table. That is the case for it: if you also want AI chat, writing help, grammar checks, webpage and PDF translation and a mind map generator, Pro at US$8.3 a month or US$99 a year covers all of it, with 5,000 basic model queries and 200 advanced model queries a month and 1,500 advanced credits. Paid plans include YouTube video summarization, webpage and file summaries and ChatPDF, while the free plan has 40 basic model queries a day and only a limited trial of YouTube summaries. Monica runs as a Chrome and Edge extension, on Windows and Mac and on Android and iOS, and Pro allows 5 login devices. The weak points for video-only users are the cap on advanced queries and the fact that you pay for many tools you may not use; NoteGPT is a closer fit if summaries are all you need.

Notta is a transcription service first, and its YouTube video summarizer suits people who also need accurate text of what was said. Paste a link, choose one of 50+ summary languages and you get a summary with a transcript; the Chrome extension summarizes a YouTube video in a click with timestamp breakdowns. The same account transcribes meetings, uploaded files in formats such as MP4, MOV and WMV and live speech, in 58 transcription languages. Pro costs $8.17 a month billed annually, or $97.99 a year, and includes 1,800 transcription minutes, recordings up to 5 hours, 100 file uploads and 100 AI summaries a month, plus exports and transcript translation. The free plan is a trial in practice: 120 minutes a month, up to 3 minutes per conversation and 10 AI summaries. If you only summarize YouTube videos and never need a transcript, NoteGPT gives more for a similar price.

Readwise Reader is a reading app first, but it accepts YouTube videos as one of its saved formats, so videos land in the same queue as articles, PDFs, EPUBs, emails, RSS feeds and X threads. Its Ghostreader AI summarizes, explains and translates any document you save, and everything can be highlighted and found again with full-text search. Text to speech is built in. The Reader only plan costs $7.99 a month billed yearly; Full Readwise at $9.99 a month billed yearly adds Readwise Highlights, which syncs Kindle and other highlights, and Daily Review. That makes it a good home for people who already read a lot and want video notes in the same place. It is a weaker fit for someone who only wants quick YouTube summaries: there is no permanent free plan, and the app has more views and settings than NoteGPT or Gemini.

HARPA AI is a browser extension for people who want an AI assistant that acts on web pages, and its YouTube Summarizer is included on every paid plan. The for Everyone plan costs $12 a month billed annually with 75 Megatokens a year and access to cloud models such as GPT-5.4, Sonnet 4.6, Gemini 3.1 Pro, DeepSeek V3, Perplexity Pro, Grok 4.1 and Llama 4, plus features to summarize PDFs, files and YouTube. You can also connect your own API keys or use web session connections to the AI services you already pay for. The for Pros plan is $19 a month billed annually with 225 Megatokens a year, and a lifetime plan is $240 paid once for a single user. The free DEMO plan allows 10 messages a day and up to 100 total AI command runs. The token system and automation features make HARPA more than most people need for summaries alone.

Sider has grown from a ChatGPT sidebar into a broader AI workspace, and YouTube Summary is one of its listed premium features. Every plan includes every feature: chat with models from OpenAI, Anthropic, Google, DeepSeek and others, summaries of long articles, translation of webpages, PDFs and images, Sider Hand for automating tasks across real websites, and tools for generating images, videos and slides. Plans differ by monthly credits and cloud computer power, from Nano at US$10 a month to Lite at US$25, Pro at US$50 and Max at US$100. Lite and above include a dedicated cloud computer that runs Sider Hand around the clock. Yearly billing takes up to 17% off and adds 20,000 bonus credits a month. For video summaries alone, this is the most expensive entry point on the list, and the public pricing page does not show how many credits each plan includes.
