Auto-transcribe Hindi audio, translate each line with a subtitle-trained GPT-5.4 model, edit against the video, and export a finished .srt or a burned-in MP4. The sarcasm, the yaar, the "arre bhai" — all intact.
Add English subtitles to unlock the massive non-Hindi-speaking audience on YouTube. Videos with captions get ~15% more watch time and 40% more international impressions.
Reels, dialogue compilations, meme edits — LinguaSub keeps the sarcasm, punchlines and character voice intact instead of flattening them into robotic English.
Coaching classes, EdTech creators, professors — reach students who prefer English or don't speak Hindi natively without re-recording anything.
Send NRI relatives a subtitled version of family video messages, speeches, and events.
Interview-heavy footage in Hindi can be exported with clean English subtitles for international festival submissions.
Internal town halls, leadership videos, or training modules recorded in Hindi can be pushed to global teams in minutes.
YouTube's auto-translate is literal, word-for-word, and often robotic — 'ye toh kamaal hai' becomes 'This is wonderful' instead of the natural 'Damn, that's amazing.' LinguaSub uses GPT-5.4 with a subtitle-specific prompt that preserves tone, sarcasm, honorifics, and Hinglish.
Yes — Hinglish is one of the hardest cases for generic tools because they can't decide which language to treat it as. LinguaSub reads the whole transcript for context, then translates each segment into natural English while keeping proper nouns intact.
Yes, though Whisper's models are strongest for standard Hindi. For regional dialects we send Whisper a dialect-aware prompt so it still captures the audio, then GPT-5.4 handles idiomatic phrasing in translation. Accuracy is highest on clean audio.
Roughly 45 seconds transcription + 20 seconds translation + 30 seconds burn-in ≈ under 2 minutes total. You'll be downloading the finished subtitled MP4 while your coffee is still hot.
Yes. Any paid plan grants full commercial rights. Free-tier output is fine for personal, educational, or open-source use. See /terms.
Open the edit panel, click that segment, retype the English, hit save. Re-render if you want the fix baked into the video. Takes 30 seconds.
