Octavia: The world's most advanced AI dubbing platform.

Octavia is an advanced AI dubbing and video-translation platform that transcribes, translates, subtitles, and re-voices video and audio in 60+ languages. Its context-aware models preserve meaning, terminology, timing, tone, and speaker delivery across short clips and videos up to 10 hours long. Users can review transcripts, select voices, edit translations, and generate natural multilingual content from one platform.

Hello Product Hunt! 👋 We are excited to introduce Octavia, built by the team at LunarTech. We created Octavia because translating high-quality video content remains slow, expensive, and inaccessible to most creators, educators, companies, and institutions. With Octavia, you can upload a video or audio file and: 🌍 Translate it into 60+ languages 🎙️ Generate natural, expressive dubbed voices 📝 Create and translate transcripts and subtitles 👥 Process multiple speakers ✏️ Review and edit everything before generating the final audio ⏱️ Translate long-form videos of up to 10 hours as one continuous project Our context-aware system is designed to preserve meaning, technical terminology, numbers, tone, and timing throughout the entire file—not simply translate isolated sentences. Octavia is now live, and you can create a free account today: https://octavia.lunartech.ai/ We would love to hear what you create, which languages you test, and where you think Octavia can improve. Thank you for supporting our launch! 🚀

Tried a 15-minute Spanish interview and the dubbed audio actually sounded like the same person speaking English. Timing held up well even on quick back-and-forth segments, which is usually where these tools fall apart for me.
