What platforms does SubGrab support?

SubGrab supports 15 video platforms: YouTube (including Shorts), Facebook (videos & Reels), Instagram (Reels & video posts), X/Twitter, TikTok, Vimeo, Loom, LinkedIn, Dailymotion, Twitch (Clips & VODs), Wistia, Brightcove, Reddit, Rumble, and Bilibili. Just paste any video URL.

Every new account gets 2 free credits — no payment required. Each action costs 1 credit: extracting a transcript, AI transcription (up to 60 minutes per credit), or generating an AI summary. Your very first summary is also free. After your free credits, credit packs start at just $1.99 for 3 credits. Credits never expire.

What if the video has no captions?

SubGrab detects when captions are unavailable and offers AI transcription instead. AI transcription costs 1 credit for videos up to 60 minutes. Longer videos cost 1 credit per 60 minutes (e.g. a 2-hour video costs 2 credits). It works for any video with audible speech, across all 15 platforms.

What are credits and how much do they cost?

Credits are used for every action: extracting captions (1 credit), AI transcription (1 credit per 60 minutes of video), or AI summary (1 credit). Every new account gets 2 free credits. Credit packs: 3 for $1.99, 10 for $4.99, 30 for $9.99, 80 for $19.99, or 200 for $39.99. Credits never expire.

Do I need an account?

Yes, a free account is required. Signing up takes seconds via magic link email — no password needed. Every new account gets 2 free credits to get started.

What is an AI summary?

After extracting a transcript, SubGrab can generate a structured AI summary with key takeaways, a timestamped timeline of topics, and notable quotes. Summaries cost 1 credit — but your very first summary is free. Perfect for quickly understanding long videos without reading the full transcript.

How accurate is the AI transcription?

Our AI achieves 98%+ accuracy for clear speech and supports 90+ languages. Accuracy may vary depending on audio quality, background noise, and accents. For most videos with clear audio, you can expect near-perfect results.

What formats can I download transcripts in?

You can download transcripts in three formats: TXT (plain text), SRT (SubRip subtitle format), and VTT (WebVTT format). You can also copy the full transcript to your clipboard with one click.

Does SubGrab work with YouTube Shorts?

Yes. SubGrab supports YouTube Shorts URLs. Paste a Shorts URL (youtube.com/shorts/VIDEO_ID) and extract the transcript the same way as a regular YouTube video. Most Shorts have auto-captions that SubGrab can extract.

Can I transcribe Facebook and Instagram videos?

Yes! SubGrab supports Facebook videos, Facebook Reels, Instagram Reels, and Instagram video posts. Since these platforms don't offer transcript downloads, SubGrab uses AI to transcribe the audio. Just paste the video URL — facebook.com/watch, facebook.com/reel, instagram.com/reel, or fb.watch short links all work.

Does SubGrab work with X/Twitter videos?

Yes. Paste any tweet URL containing a video from x.com or twitter.com. SubGrab uses AI to transcribe the audio. This is especially useful for journalists and researchers who need exact quotes from video tweets.

Can I download Loom transcripts?

Yes! Loom auto-generates transcripts but locks them inside the player — you can't copy or download them. SubGrab lets you extract a downloadable transcript from any Loom recording as TXT, SRT, or VTT. Paste any loom.com/share/ URL to get started.

Can I transcribe Twitch VODs?

Yes! SubGrab supports Twitch VODs up to 4 hours long. Since VODs don't have captions, our AI transcribes the audio directly. Credit cost is 1 credit per 60 minutes — so a 2-hour VOD costs just 2 credits. This is especially useful since Twitch broadcasts expire after 14 days — save the transcript before it's gone.

How does SubGrab compare to YouTube's built-in transcript?

YouTube's built-in transcript is only accessible on desktop, cannot be downloaded, and isn't available when a video has no captions. SubGrab lets you download transcripts as files (TXT/SRT/VTT), works on 15 platforms, and can generate transcripts for videos without captions using AI.

We don't store video content. We only save the transcript text and basic video metadata (title, thumbnail). For AI transcription, the audio is processed and immediately deleted after transcription. No tracking, no ads, no third-party sharing.

No. Credits never expire. Buy once, use whenever you need them. There are no subscriptions or recurring charges — just one-time credit packs.
