Two very similar credit-based transcript tools, compared on the details that actually differ.
Try JotVox free →SubGrab and JotVox are the closest match on this list. Both take a video link, grab existing captions instantly, and fall back to AI transcription when a video has none. Both quote 98%+ accuracy, both sell credits rather than forcing a subscription, and both say audio is processed in memory and not stored.
SubGrab lists 28 platforms including Loom, Rumble, Wistia, Brightcove, Kick, Naver TV and WeTV, exports TXT, SRT and VTT, gives 2 free credits on signup, and sells credit packs starting at $2.99 at the time of writing.
JotVox lists 19+ platforms, exports TXT, SRT, VTT and MP3, gives 3 free credits plus one free AI transcription a day after email verification, and offers credits from $4.99 or plans from $9 a month.

SubGrab reaches business video and streaming platforms JotVox does not: Loom, Wistia, Brightcove, Rumble, Kick, Naver TV and WeTV. If you transcribe internal Loom recordings, that alone decides it.
JotVox goes further into Chinese platforms, with Xiaohongshu and Tencent Video alongside Bilibili and Weibo. Both lists change, so compare the current platform pages.
The free allowances differ in shape. SubGrab gives 2 credits on signup. JotVox gives 3, and adds one free AI transcription per day once your email is verified, which suits anyone who needs a transcript most days.
On exports, JotVox adds MP3 to the shared TXT, SRT and VTT set. That only matters if you want the audio itself, but it is a real difference.
Pick SubGrab if its platform list matches your sources better. Loom, Wistia and Brightcove are common in workplaces, and Rumble, Kick and Naver TV cover creator and regional ground JotVox does not.
Its pricing is also simpler if you never want a subscription: one-time credit packs, credits that do not expire, and a lower entry price at the time of writing. For light and occasional use, that is a fair deal.
Mostly, with one caveat. The flow, the free-captions behaviour, the credit model and the accuracy claims all line up closely. The caveat is platform coverage: SubGrab lists Loom, Wistia, Brightcove, Rumble, Kick and Naver TV, which JotVox does not. Check your usual sources against both lists first.
JotVox gives slightly more to start: three credits on signup versus two, plus one free AI transcription per day once your email is verified. Both grab existing captions free without an account, which covers most YouTube videos at no cost. For daily light use, the recurring free transcription is the bigger factor.
Both state that they do. SubGrab says audio is processed in memory and deleted immediately after transcription, and never stores video files. JotVox states the same: audio is processed in memory and deleted right after transcription. If this matters for your work, read both current privacy policies rather than relying on marketing copy.
MP3. Both export TXT, SRT and VTT, so the text and subtitle side is equivalent. JotVox adds an audio export, which is handy for pulling a clip out of a podcast or keeping the source audio alongside the transcript. Otherwise the export options are effectively the same.
These two are close enough that platform coverage should decide it. Pick SubGrab if you need Loom, Wistia, Brightcove, Rumble or Kick, or want the cheapest entry credit pack.
Pick JotVox if you need Xiaohongshu or Tencent Video, want MP3 export, or value the daily free AI transcription on a verified account.
