Hey Product Hunt
I built Translator because I was frustrated with existing video translation tools. They were either:
- Expensive subscription services ($30+/month)
- Cloud-based (I didn't want to upload my videos to random servers)
- Produced robotic, awkward translations
So I built what I actually wanted to use.
The thing I'm most proud of is the two-pass translation system. Instead of just running text through one AI model, we use GPT-5.1 for the initial translation, then Claude Opus 4.5 reviews it for quality - catching idioms, cultural nuances, and awkward phrasing. It's a translator AND an editor.
Free forever:
- Video downloading
- Subtitle editing & merging
Actually affordable - No subscriptions. Pay-as-you-go: - $1 = ~50 min of video - $5 = ~8 hours - $10 = ~18 hours - $50 = ~127 hours Or unlock BYO API keys for $10 one-time and pay direct API costs forever. Cloud tools charge $30+/month whether you use them or not.
The whole thing is open source, so you can see exactly how it works (or contribute!).
I'd love your feedback - what languages matter most to you? What features would make this more useful?
Thanks for checking it out!
@mikey1384Β Congrats on the launch Mikey. Love the 2 pass idea. What are you seeing in terms of localization accuracy?
@zolani_matebeseΒ Thanks Zolani - the two-pass system patches a lot of holes that single pass misses. GPT-5.1 handles the heavy lifting (but with quickness and cost efficiency), then Claude-4.5-Opus catches awkward phrasing, idioms that don't translate well, and cultural context issues. I've been using it for 1+ year for videos I post on my own YouTube channel (https://www.youtube.com/@stage_5) and the quality difference vs single pass has been noticeable.

How many languages are supported as of now?
@priyanka_madirajuΒ Currently 40 languages! Grouped by region:
East Asia: Korean, Japanese, Chinese (Simplified & Traditional), Vietnamese
Europe: Spanish, French, German, Italian, Portuguese, Russian, Dutch, Polish, Swedish, Turkish, Norwegian, Danish, Finnish, Greek, Czech, Hungarian, Romanian, Ukrainian
South/Southeast Asia: Hindi, Indonesian, Thai, Malay, Tagalog, Bengali, Tamil, Telugu, Marathi, Urdu Middle East/Africa: Arabic, Hebrew, Farsi, Swahili, Afrikaans
If there's a language you need that's not on this list, let me know - adding new ones is pretty straightforward.
Two-pass translation, local processing, BYO keys, and open source is a rare combo that actually respects developers and creators.
Pricing feels fair and approachable. Excited to see where this goes, Kudos on the launch
@anupamsingh0211Β Really appreciated :) Wanted to build something I'd actually use myself - glad the pricing feels right
Congrats!!
Quick question, does it support uploading existing local video files (not just YouTube downloads)?
Would love to chat more about it and potentially try it out for some upcoming multilingual projects we have :)
@cathcormΒ Yes it works with any local video file - mp4, mkv, mov, etc. The YouTube download is just a convenience feature (also works for Twitter/X, TikTok, Instagram, and many others, as long as you have the link). Would love to hear how it goes with your multilingual projects!
@mikey1384Β i'll keep you updated of course!!
thanks for your answer <3
Congrats on the launch, Mikey.
The two-pass translation idea makes a lot of sense especially for video where literal translations usually sound off.Nice touch treating it as translation + editing instead of just running text through a model once.Also like the pay-for-usage + BYO keys approach. Feels fair and flexible compared to most tools in this space.
Slang and casual phrasing usually break most tools interested to see how this handles that.
Nice work shipping this.
@syed_hassan9Β Yep, that's exactly why the two-pass exists. Claude's review step is specifically good at catching when something sounds "technically correct but weird" and rephrasing it naturally. Battle-tested it on YouTube content for over a year - https://www.youtube.com/@stage_5
@mikey1384Β That makes sense. That βtechnically correct but weirdβ gap is exactly where a lot of AI outputs fall apart in real use.Interesting that youβve battle-tested this on YouTube content long-form and spoken language tends to expose those issues fast. Would be interesting to hear where the second pass adds the most value in practice (tone, flow, context, etc.).
@syed_hassan9Β Great question. GPT-5.1 (without thinking) often translates literally. Claude catches "break a leg" becoming "λ€λ¦¬λ₯Ό λΆλ¬λ¨λ €" in Korean (literally break your leg) and fixes it to "νμ΄μ λΉμ΄" (good luck) - this is not always the case, of course, but I'm just illustrating an example so you get the idea
@mikey1384Β Thatβs a perfect example idioms are where literal translation really falls apart. Optimizing for intent over strict accuracy feels like the right call.

@curiouskittyΒ Great question!
Three concrete wins over cloud tools:
1. Privacy + Speed - Videos never leave your computer. No uploading, no waiting, no privacy concerns for unreleased content.
2. Actually affordable - No subscriptions. Pay-as-you-go: - $1 = ~50 min of video - $5 = ~8 hours - $10 = ~18 hours - $50 = ~127 hours Or unlock BYO API keys for $10 one-time and pay direct API costs forever. Cloud tools charge $30+/month whether you use them or not.
3. Quality - Two-pass translation. GPT β Claude review (you can toggle the review phase on or off btw) catches awkward phrasing.
Plus features cloud tools don't have: auto-highlight detection for TikTok/Shorts clips, AI summaries, voice cloning for natural dubbing, and 4 subtitle style presets. The highlight clipper alone is a game-changer - it identifies key moments and exports vertical clips ready for social media.
We created the same service 3 years ago β 70+ languages π YouTube even officially recommended us. So if you need help with development, feel free to reach out ;)
