Which one should you choose?

Choose SumAI if

  • You want a native iPhone or iPad app rather than a website.
  • You want to share from YouTube or Safari and read the summary in the same place.
  • You want five summary depths and a library with search, favorites and tags.
  • You prefer a simple price: one weekly or yearly plan.
  • You want summaries read aloud.

Choose NoteGPT if

  • You work mainly on a computer.
  • You need to summarize a video that has no captions.
  • You want to upload audio or video files, slides or images.
  • You want to process playlists or batches of videos.
  • You want extra generators, such as slides or podcasts from your notes.

A suite and an app

NoteGPT has grown into a broad set of tools on the web: a YouTube summarizer, a PDF summarizer, audio and video transcription, mind maps, flashcards, quizzes, and generators for slides and podcasts. Its Chrome extension reports 400,000 users. If you study at a laptop and want one website for many kinds of material, that breadth is the appeal.

SumAI is narrower by design. It is an iPhone and iPad app that takes three kinds of source (YouTube videos, web articles, PDFs) and gives each one the same treatment: a summary in the style you choose, key moments, Ask AI, a mind map, a quiz, flashcards and a place in your library.

The biggest practical difference: captions

SumAI needs a video to have captions or auto-generated subtitles. Most talk-based videos do. Some do not.

NoteGPT says it can handle videos without subtitles by transcribing the audio. Its pages give caps of 120 minutes on the Pro plan and 210 minutes on the higher plans, and its extension listing says such videos use more of your quota. If the videos you care about often lack captions, that capability matters and SumAI does not have it.

Phone or computer

NoteGPT runs in a browser. You can open it in Safari on an iPhone, but its website does not link to an official iPhone app.

SumAI is native. That brings things a website cannot do as easily: sharing straight from the YouTube app or Safari into SumAI, and a library that lives on the device.

Inputs

NoteGPT accepts more: playlists and batches of YouTube videos, local audio and video files, slides and images, as well as PDFs and web pages.

SumAI accepts a YouTube link, a web link or a PDF with selectable text, one at a time.

Pricing

NoteGPT’s pricing page lists Pro at $9.99 a month or $108 a year, with larger plans above it, and counts usage in quotas and credits. Its Chrome listing mentions 15 free quotas a month.

SumAI is free to download, with one optional Premium subscription at $2.99 a week or $29.99 a year in the US.

A caution on reading NoteGPT’s pages: a few details differ from page to page, such as the number of supported languages and the cap for videos without subtitles. We have used the pricing page where they disagree. Check the current figures before you subscribe.

Bottom line

Choose by where you work and what you feed it. A computer, mixed file types and videos without captions point to NoteGPT. An iPhone, links and PDFs, and a preference for one simple app point to SumAI.
