What platforms does SubGrab support?

SubGrab supports 28 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, Bilibili, SoundCloud, Kick, Apple Podcasts, Vidyard, Odysee, Niconico, Naver TV, CHZZK, SOOP (AfreecaTV), WeTV, and Weibo — plus video and audio files shared from Google Drive and Dropbox. Just paste any video, audio, podcast, or file-share 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, on top of the signup credits. After your free credits, credit packs start at $2.99 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 28 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 $2.99, 10 for $5.99, 30 for $11.99, 80 for $22.99, or 200 for $44.99 (the Power pack is the best per-credit value at $0.22 each). Your first purchase includes bonus credits on every pack — for example the $11.99 Popular pack gives 50 credits (30 + 20 bonus) the first time. 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, plus your first AI summary is free on top of that.

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.

Is there a first-purchase bonus?

Yes — your very first credit purchase includes bonus credits on every pack, applied automatically. For example: Micro gives 5 credits instead of 3, Starter 15 instead of 10, Popular 50 instead of 30, Pro 120 instead of 80, and Power 300 instead of 200. The bonus applies once, to your first pack only, and the credits never expire.

How do I buy more credits?

Hit 'Buy Credits' anywhere you see it — on the pricing page, the dashboard, the header, or from the in-app prompt that appears when you run out. Checkout is Stripe-hosted: enter your card once, the next purchase is 1-click. Your card is saved securely with Stripe (we never see or store card numbers) and can be removed any time from the dashboard.

Is 1-click purchase secure?

Yes. SubGrab uses Stripe (PCI Level 1, the highest payment-security standard) to handle all card data. Your card is tokenised by Stripe and never touches our servers — we only store an opaque Stripe customer ID. When you make a repeat purchase, the charge happens off-session on the same saved card and is governed by the same fraud + 3-D Secure protections as the first transaction. You can remove the saved card from your dashboard at any time.

Can I get a refund if something goes wrong?

Yes. Credits are automatically refunded if an extraction or AI transcription fails — you only pay for successful results. If you bought a credit pack and want a refund within 7 days of purchase, email help@subgrab.com and we'll process it.

I haven't used SubGrab in a while — is my account still there?

Yes. Your account, your credits, and your past transcripts are all still there — they don't expire and aren't deleted for inactivity. Just sign in with the same email you signed up with (magic link will arrive in seconds). If you've forgotten which email you used, write to help@subgrab.com from any address that might match.

How do I stop or change email notifications from SubGrab?

Every marketing or product-update email we send carries an Unsubscribe link in the footer — one click unsubscribes you immediately. Gmail and Outlook also surface a built-in Unsubscribe button at the top of our messages. You'll still receive essential account emails (sign-in links, payment receipts, security notices) since you need those to use the product — there's no way to turn those off short of deleting your account (which you can request via help@subgrab.com).

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.

Can I transcribe podcasts or audio (SoundCloud, Apple Podcasts)?

Yes. SubGrab transcribes audio, not just video. Paste a public SoundCloud track or an Apple Podcasts episode link (the one with ?i= for a specific episode) and the AI turns the audio into a full, timestamped transcript. It's ideal for show notes, pulling exact quotes, and making long episodes searchable — and you can generate an AI summary to read an hour-long episode in a minute.

Can I transcribe a video or audio file from Google Drive or Dropbox?

Yes. Set the file to 'Anyone with the link', copy the share link, and paste it into SubGrab — it reads the media straight from Google Drive or Dropbox and transcribes it with AI. No download and no re-upload. This is great for recorded meetings, lectures, voice memos, and raw footage that was never published to a video platform. The most common reason a link fails is permissions: a private/restricted file can't be read, so make sure it's shared.

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 28 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.
