An AI browsing assistant compared with a dedicated video and audio transcript tool.
Try JotVox free →Kome is a browser extension. Its main pitch is summarizing articles, web pages, news and YouTube videos with one click, plus a bookmark manager and a Smart Compose feature that drafts emails and posts from what you have saved. It runs on Chrome, Edge, Opera, Brave and Arc.
Kome also publishes a free YouTube Transcript Generator: paste a link, get the text, copy it. Its page states support for over 120 languages and that the tool is free with some limits.
JotVox is a transcript tool first. It takes links from 19+ platforms or files from your device, Google Drive or Dropbox, returns existing captions free with no sign-up, and runs AI transcription when a video has no captions.

Kome is designed to help you get through content faster. Summarize the page, save the bit that mattered, reuse it in a draft. The transcript generator supports that loop rather than being the destination.
JotVox assumes the transcript is the deliverable. That means timed subtitle files, not just clipboard text: SRT for editors, VTT for web players, TXT for notes, MP3 for the audio. See SRT, VTT and TXT.
Kome's transcript tool is aimed at YouTube. JotVox handles YouTube too, and then keeps going: TikTok, Instagram, X, Facebook, Twitch, SoundCloud and podcasts.
The regional coverage is the sharper difference. Bilibili, Xiaohongshu, Weibo, Tencent Video and Niconico are on the JotVox platform list and rarely appear elsewhere.
Choose Kome if the friction you feel is in browsing, not in transcribing. Summarizing whatever page is in front of you, without switching tabs or pasting URLs, is a genuinely faster loop, and JotVox has no equivalent.
The bookmark manager is the other reason. If you save a lot and lose track of it, having summaries, saved snippets and AI drafting in one extension is worth more than transcript file formats you would never open.
No. They overlap only on YouTube transcripts. Kome is a browser assistant with summarizing, bookmarking and AI writing built around your everyday browsing, and JotVox does none of that. JotVox replaces the transcript piece and extends it to 19+ platforms with subtitle exports, but the extension workflow is Kome's own.
Yes. Every JotVox transcript can be exported as TXT, SRT, VTT or MP3. SRT and VTT carry timestamps, which is what video editors and web players need. Clipboard-only tools give you the words but not the timing, so they suit note-taking better than subtitle production or editing work.
JotVox switches to AI transcription of the audio, reporting 98%+ accuracy across 99 languages and charging one credit per action. This matters most on short-form social video, livestream replays and non-English uploads, which often ship with no caption track at all for a downloader to find.
No. JotVox runs 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. There is no extension to install and no account needed to grab existing captions. Accounts only come in for AI transcription and summaries.
Pick Kome if you want an assistant that follows you around the web, summarizing and saving as you browse, with a free YouTube transcript tool alongside it.
Pick JotVox if you need the transcript as an actual output: many platforms, subtitle file exports, and AI transcription for the videos that have no captions to begin with.
