SubtitleFlow

SubtitleFlow helps YouTubers, podcasters, and content teams localize videos into 100+ languages in minutes. Three things make it different: 1. Zero-drift timestamps — timing stays frame-accurate after translation, even when target language length differs significantly from the source. 2. Custom glossary — upload your brand names, character names, or technical jargon once and they stay consistent across every language. 3. GPT-powered deep translation — captures tone, idioms, and context that literal MT misses. Supports MP4, MOV, WebM, MP3, WAV, SRT, VTT. Free tier (3 videos/day), paid plans from $10/month. No credit card required to start.
