FAQ

AI Growth Kit is a growing collection of AI video tools for creators and marketers. Today we ship three tools: Video Translator (regenerate the audio track of any video in 20+ languages), Subtitler (auto-generate burned-in or SRT subtitles), and 4K Upscaler (AI super-resolution). One subscription, one credit balance, every tool we ship.

One credit equals one second of output video. A 30-second translation, subtitling, or upscale job costs 30 credits. Credits are universal across all tools — subscribe once, use everything. Subscription credits reset monthly; one-time credit packs never expire.

Most jobs finish in 2-5 minutes per minute of input. You don't have to wait on the page — leave the tab open or check "My tasks" later. We refresh status every 5 seconds automatically.

You get a full refund. The credits consumed for any failed task are automatically returned to your balance, no action needed on your part. We also send an email explaining what went wrong.

We accept MP4, MOV, and WebM video files up to 500 MB. For best results, use HD source (720p+) with clean audio. The clearer the input, the better the output.

Translator and Subtitler support 20+ languages including English, Mandarin, Spanish, Hindi, Portuguese, French, German, Japanese, Korean, Arabic, Indonesian, and more. Translation regenerates the audio track without modifying the original footage.

No. Translation only regenerates the audio track in the target language and re-aligns it to the original video timing. The original visuals — including the speaker's face and mouth — are not modified.

Yes. Cancel from your account portal. You'll keep access to remaining subscription credits until the end of the billing period. One-time top-up credits never expire — they stay in your account forever.

Your uploaded files are stored in private Cloudflare R2 storage. We don't share them with anyone. After 30 days, we automatically delete the source files. Outputs are stored on our CDN — you can download and host them anywhere.

API access is on the roadmap for the Pro tier. If you have a production use case requiring API access today, email thcbnu@gmail.com with details.

Subscription credits reset on each billing cycle (use them or lose them). Top-up pack credits never expire — they're a permanent addition to your balance. We always consume subscription credits first (so they don't expire unused), then top-up credits. You can mix both freely.

Yes. Roadmap includes more video tools and creator-focused AI utilities. Your subscription unlocks every tool we ship — no extra fees.
