Does my video get uploaded to a server for transcription?

No. The Whisper AI model downloads into your browser once and transcription runs entirely on your device. Your video and audio never leave your computer or phone.

Which languages can it generate subtitles in?

Hindi (Devanagari), English and auto-detect are supported for speech recognition. Any transcript can also be displayed as Hinglish (Roman script) using the built-in transliteration toggle.

Can I edit subtitle timings after auto-generation?

Yes. Every subtitle appears as a block on the visual timeline — drag it to shift, pull its edges to change start/end, split or merge cues, nudge by 0.1s, and watch the video preview update live.

How to Make Subtitles from a Video — Step by Step

Load media: drop your video (or just an audio/podcast file). It plays on the right — nothing is uploaded anywhere.
Run the AI: pick language (Hindi / English / auto), choose Tiny / Base / Small model and press "Auto-Generate Subtitles". The Whisper model runs inside your browser.
Edit on the timeline: each subtitle is a block — drag to move, pull edges to adjust start/end. In the cue list you can retype text, split or merge cues, and nudge timings by ±0.1s.
Hinglish mode: toggle "Hinglish (Roman)" to show Devanagari subtitles in Roman script — great for reels and shorts.
Export: download the finished SRT (YouTube / VLC / editors) or VTT (web players), or a plain text transcript.
