Films, audio and projects stay on your PC. Speech to text, voices and on-device translation work offline. Only what you choose to send to AI leaves it.

/Our mission
To let one video maker have a Vietnamese dub of a film in minutes, on their own PC, and still be the one who decides the final cut.
01 //Why choose
Why HANAVI is not a translation service
You decide the final cut
AI drafts on the timeline: translated lines, casting, cuts. You edit right in the table before exporting; nothing is exported before you have seen it.
Clear pricing
Free to start. Plans and credits show their numbers before you buy; failed AI requests are refunded.
Weekly updates
Features arrive every week and updates download themselves inside the app. We read every bug report and suggestion.

04 /Q&A
Frequently asked questions
Where are my films and projects?
On your PC, in the folder you choose. Only what you send to AI leaves it.
Which films can I use?
Only films you have the right to use. HANAVI works with video files on your PC; it does not download from other platforms.
Do I need an internet connection?
Editing and dubbing with on-device voices work offline. Translation through HANAVI's server, film summaries and AI drafts need a connection and an account.
What does my PC need?
Windows 10 or 11, 64-bit. Processing time depends on the film and your PC. The integrated library lets you download only the parts you use.
How do I buy a plan?
In the app, open Account › Buy, pick a plan and pay by bank transfer with the QR code. Once approved, the plan activates itself.
