How can we help?

Yes. First visit assigns an anonymous account with a free quota. No sign-up or card — all five core tools are available right away.

Free history and quota live in this browser. Switching devices or clearing cache loses them, and signing up cannot restore those local records. Registration is mainly for binding orders and logging in. Plus processing happens in your dedicated space.

On the login page tap “Forgot password”, enter your registered email, and you will get a reset link valid for 30 minutes. Open it and set a new password.

Free gives each core tool (captions, dubbing, translation, covers, script assist) its own 1 run / month. They do not share a pool, and they refresh monthly. Picking only dubbing or translation does not spend an extra caption run for internal speech recognition.

After payment we open a dedicated high-performance remote device for you and email the connection details. Sign in there for unlimited caption and audio processing. This computer has 20 runs per tool per month.

Yes. Plus is $20 / month. To stop renewal, email support@aivideocap.com with your order id or registered email. You can keep using the paid period; after it ends you drop back to Free.

Free recognition and synthesis run in your browser. The video file is not uploaded to our public processing servers. Plus runs in a dedicated space that is only yours.

After recognition you can edit line by line in the editor. Speech-to-text currently supports Mandarin and English. If the frame has hard-subs, switch to on-screen OCR. Heavy background noise or a strong accent: clean up the recording first, then proofread.

Confirm the file is MP4 / MOV / AVI / MKV and ideally under 200MB at 1080p. Free videos longer than 15 minutes are rejected. Files over 300–500MB may also fail if the browser runs out of memory. If it hangs, close other tabs, refresh, and retry, or ask live support.
