Got questions?
Frequently asked
Does it work without internet?+
Yes, completely. AutoCaptioner uses on-device AI — once you download the model (a one-time step), the app generates captions entirely offline. No internet required.
Can I edit individual words in my captions?+
Absolutely. The timeline editor lets you tap any word to edit its text, timing, or style. You can also split segments, delete silences, and rearrange clips.
What languages are supported?+
99+ languages, including English, Hindi, Hinglish, Spanish, Arabic, French, Portuguese, Japanese, and many more. There is also an auto-detect option.
Can I record directly in the app?+
Yes! AutoCaptioner has a built-in smart recorder with a teleprompter mode (so you never forget your script), faceless recording for voiceover content, and cinematic filters.
Is it really completely free?+
Yes, 100% free. Because processing happens on your device and not on our servers, we have no infrastructure costs to pass on. There are no subscriptions or hidden tiers.
Will my videos have a watermark?+
No watermarks. Ever. Your exported video is clean, full quality, and ready to post to TikTok, Instagram Reels, YouTube Shorts — or anywhere else.
