Eightify alternatives for YouTube video summaries in 2026

Compare Eightify alternatives by why you are switching: no extension, a free extension, playlists, Instagram Reels, or research across videos and documents.

Short answer

Pick the Eightify alternative by the reason you are switching. Use SummarizeVideo.ai to paste a public video URL without installing an extension, Glasp's free YouTube Summary extension to stay inside YouTube, NoteGPT to process several YouTube videos or playlists, or Gemini Notebook (formerly NotebookLM) to study captioned videos beside your documents.

Paste a public video URL and get the summary before deciding whether to watch it.

Summarize a video

Eightify is a YouTube summary extension with iOS and Android apps. Its Chrome Web Store listing describes a 7-day free trial followed by a subscription, timestamped summaries, transcripts, comment overviews, and summaries in 40+ languages for videos up to 10 hours long.

I build SummarizeVideo.ai, so I list the limits of my own tool too. I checked each product's official page or store listing on October 12, 2026. Prices and limits change, so check the current page before paying.

When Eightify is still the right tool

Eightify fits when you watch on YouTube and only need the main points before deciding whether to watch. The summary opens next to the video, the timestamps jump to the matching part, and the comment overview shows what viewers said. Stay with Eightify if the subscription is worth it to you and you use it most days.

Pick the alternative by why you are switching

  • The trial ended and you want a free option inside YouTube: Glasp's YouTube Summary with ChatGPT & Claude extension.
  • You do not want a browser extension: SummarizeVideo.ai or NoteGPT, both in a normal browser tab.
  • You summarize Instagram Reels as well as YouTube: SummarizeVideo.ai.
  • You need several videos or a whole playlist at once: NoteGPT.
  • You want to ask questions across videos, PDFs, and websites: Gemini Notebook.

SummarizeVideo.ai: paste a URL, no extension

SummarizeVideo.ai works in any browser. Paste a public YouTube or Instagram Reel URL, sign in, and get a summary with a searchable transcript you can copy. Chapter timestamps appear when the video has chapters. A free account includes 2 summaries per day, and summaries can be written in 9 languages.

When YouTube captions are missing, SummarizeVideo.ai tries to transcribe the video's audio instead. That fallback covers videos under 90 minutes. Eightify's 10-hour limit is the better fit for very long podcasts without captions.

SummarizeVideo.ai has no chat, no mobile app, and no public share links. It handles one video at a time.

Glasp: a free extension inside YouTube

Glasp's YouTube Summary with ChatGPT & Claude is the closest workflow to Eightify. Its Chrome Web Store listing calls it a free extension, with in-app purchases, that summarizes YouTube videos, web articles, and PDFs. Summary timestamps jump to that part of the video, and a Copy Transcript button copies the transcript. You can also change the summary length and the prompt.

Glasp suits Eightify users who mainly want to stop paying a subscription for summaries inside YouTube.

NoteGPT: several videos and playlists in a web app

NoteGPT runs in the browser and accepts a YouTube video link or a playlist. Its YouTube page describes batch summaries of up to 20 videos at once, and the same app summarizes uploaded video, audio, and PDF files. NoteGPT's YouTube page advertises free summaries without logging in, and its paid monthly or annual plans raise the limits. Its pricing page lists a length cap for videos without subtitles on each plan.

NoteGPT suits people who process many videos in one sitting, such as a course playlist.

Gemini Notebook: research across videos and documents

Gemini Notebook, which Google previously called NotebookLM, imports a public YouTube video's captions as a source. Its help page says only public videos with captions work, only the text transcript is imported, and videos uploaded less than 72 hours ago may not import yet. Free users can add up to 50 sources per notebook.

Gemini Notebook takes more setup than a summary next to the video. Use Gemini Notebook when you want to ask questions across several videos, PDFs, and websites together.

Try your alternative on one video you already summarized

  1. Pick a video you already summarized in Eightify, with one name, number, or claim you can check.
  2. Run the same URL through the alternative you picked.
  3. Check whether the new summary keeps that detail and the caveat around it.
  4. Find the detail in the transcript and confirm the timestamp.
  5. Switch when the alternative makes that check as fast as Eightify did.
