Metafoni

What it does

Metafoni.eu helps creators and teams localize videos end-to-end: upload a file or paste a YouTube link, extract audio (vocals/music separation), generate subtitles, translate them, and generate AI voiceover in multiple languages. ​ It includes a modern React dashboard for managing projects and a comprehensive API for step-by-step processing or fully automated, queue-based pipelines with job progress tracking.

  AI dub tool I made to watch foreign language videos with my 7-year-old2024 · speakz.ai · ▲348

  Hey HN! I love watching YouTube with my 7-year-old daughter. Unfortunately, the best stuff is often in English (we're German). So I made an AI tool that translates videos directly, using the original voices. All other sounds, as well as background music, are preserved, too. Turns out that it works for many other language pairs, too. So far, it can create dubs in English, Mandarin Chinese, Spanish, Arabic, French, Russian, German, Italian, Korean, Polish and Dutch. The main challenge in building this was to get the balance right between translating the original meaning and getting the timing…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
