A social highlighter with AI summaries compared with a dedicated transcript and subtitle tool.
Try JotVox free →Glasp is a highlighting tool. You highlight web pages, PDFs, YouTube videos and Kindle books, and it collects those highlights into something you can search, share and sync to Notion. Its YouTube Summary extension summarises videos using ChatGPT, Claude, Gemini or Mistral, and it publishes a free YouTube transcript extractor.
The free plan includes unlimited public highlights, a few basic YouTube summaries a day, PDF uploads and a small monthly audio transcription allowance. Paid tiers add private highlights, advanced summaries and much larger AI limits.
JotVox does one thing: turn a video or audio link into a transcript, free where captions already exist and on credits where AI transcription is needed.

Glasp is a memory tool. The highlight is the unit, the collection is the point, and summaries help you decide what is worth keeping. Syncing to Notion turns that into a personal knowledge base.
JotVox produces a file. TXT for drafting, SRT and VTT for captions and editing, MP3 for the audio. Nothing is stored as a reading history because that is not the job.
Glasp's video work centres on YouTube, which is where most highlighting and summarising happens. Its transcript extractor is free and useful for exactly that.
JotVox covers TikTok, Instagram, X, Reddit, Twitch, SoundCloud, Apple Podcasts and Chinese platforms such as Bilibili and Weibo.
Pick Glasp if the problem is retention, not extraction. Highlighting across articles, PDFs, Kindle and YouTube in one place, then finding it again months later, is something JotVox does not attempt.
Its free tier is also generous for readers: unlimited public highlights, daily YouTube summaries and PDF uploads without paying. And letting you run summaries through ChatGPT, Claude, Gemini or Mistral is a nice piece of flexibility.
No. Glasp is a highlighting and knowledge tool spanning web pages, PDFs, Kindle and YouTube, with a social layer and Notion sync. JotVox has none of that. They overlap only on pulling a YouTube transcript, where JotVox adds 18 or more further platforms and subtitle exports.
Glasp, if the notes are the deliverable and you want them saved, searchable and synced. JotVox, if you need the raw transcript to quote from, feed into another tool, or turn into subtitles. Plenty of researchers use JotVox to get the text and their own notes app to keep it.
Its video tooling is built around YouTube, and we did not find TikTok or podcast platform support on its site. Glasp does include a monthly audio transcription allowance, so uploaded audio is covered. For pasting links from TikTok, Instagram, Twitch, SoundCloud or Apple Podcasts, JotVox is the more direct fit.
No. JotVox runs entirely in the browser as a web app. You paste a link or upload a file from your device, Google Drive or Dropbox, and the transcript appears. Glasp works primarily through a browser extension, which suits highlighting as you read but is a different kind of workflow.
Pick Glasp if you want to capture and keep what you read and watch, with summaries and highlights that stay findable later.
Pick JotVox if you want the transcript itself as a file, across far more platforms than YouTube, with SRT, VTT and MP3 exports.
