Short answers before you import.

Can I try Kiku Captions without an account?

Yes. The built-in sample stays on the iPhone, uses no account or balance, and ends with valid sample MP4 and SRT files you can share.

What do I get from my own video?

You review timed captions first. The app then shows the exact export quote before it unlocks a captioned MP4 and editable SRT with sufficient existing KikuAI balance.

Where is my video processed?

Your media is processed remotely. Server source, audio, preview, SRT, and MP4 expire automatically within 24 hours; files saved or shared on your iPhone remain under your control.
