SUBTIFYING — OFFLINE SUBTITLE MAKER

Create, edit, translate, style, and burn subtitles directly into your videos.

Download an AI model once, then generate subtitles repeatedly without an internet connection. No account, no video upload, and no cloud processing for your offline subtitle workflow.

🎬 FROM VIDEO TO FINISHED SUBTITLED VIDEO

Turn your videos into finished subtitled videos directly on your device.

Video → Speech-to-Text → Edit → Style → Burn → Export

Generate subtitles with on-device AI, edit the text and timing, customize the appearance, preview your subtitles, and export a finished video with subtitles burned in.

No separate video editor is required just to add subtitles.

📥 ALREADY HAVE AN SRT? SKIP SPEECH-TO-TEXT

Already have a subtitle file? Import an existing SRT directly into your video, then edit, style, and burn it into the video.

Video + SRT → Edit → Style → Burn → Finished Video

You can also export your subtitles as an SRT file for use in other video players or editors.

✨ ONE-TAP WORD HIGHLIGHTING

Make subtitles more dynamic with word-by-word highlighting.

Apply word highlighting with a single tap across your subtitles. No manual word timing and no need to re-transcribe your video.

Customize highlighted words with options such as font size and color, even for long videos.

📴 DOWNLOAD ONCE. TRANSCRIBE OFFLINE.

Subtifying uses AI speech recognition directly on your device.

Download the required AI model once, then use it repeatedly without Wi-Fi or mobile data. The model stays on your device so you can generate subtitles again and again while offline.

Internet access is only needed for features such as downloading AI models and displaying ads.
