"Hey Product Hunt! I'm Artur, a solo indie dev from Poland.About a year ago I shared a free subtitle tool on Reddit and the response blew me away. Since then, I've had a lot of fun working on it and I just shipped the biggest update yet: a completely rebuilt editor.The idea is simple: add dynamic, animated captions to your videos to reach a broader audience and engage your viewers. It happens entirely in your browser. No signup, no watermark, no upload to servers. Your video never leaves your device. Everything runs locally using on-device AI and browser-based video processing.What's new in this update:- Multiple caption positions in the same video- Style individual words- Text alignment, letter and word spacing- Word-level animations- Audio waveform on the timeline- New caption styles- Safe zone overlay- Search in captions editor- Rebuilt rendering engine- Refreshed UI across the boardThe browser version is completely free - and always will be. It does everything you just saw. But browsers have limits. If you need faster exports, unlimited file sizes, or custom presets - the desktop version breaks past those. One-time purchase, no subscription. Use code PRODUCTHUNT for 20% off this week.I'd love to hear what you think and what's the most annoying part of adding captions to your videos?"

"I was so happy to know that I was one of the first supporters of the project. I’ve seen a lot of potential since the very first time I visited your website, Artur. The app has become my favorite—it helps me a lot with many short videos, especially with great subtitles.I was also really happy to hear that the Linux version is now in an experimental stage—I literally screamed with joy! Wishing you lots of success, dear. May you reach an even wider audience.Signed,Little witch Hepena 🖤✨"

"An early user here as well. I found this to be the easiest to use tool of its kind and also the most accurate. it doesn't try to upsell you on thousands of different things or display tons of ads - like many other tools do. I hope it'll stay that way. Great tool!"

"This has been my go‑to app for captioning videos. The amount of customizability and the ability to export subtitles with alpha so you can easily import them into your video editor is just great. The best part is that it all works locally and there’s NO subscription. These are exactly the kinds of apps I love to see. The developer has also been super active in adding new features, and the app has already come a long way since the initial release. Wishing you the best with this launch!🚀"

"Been burned by too many "free" caption tools that watermark your exports or cap you at 2 minutes. The local processing angle is a real differentiator - especially for anyone working with client footage.Ran a quick test and the accuracy on my footage was genuinely good. The editor feels clean too, not overwhelming.Solid launch, @artur_rosa! Following this one closely."

"Been using withsubtitles for multiple (personal at the moment) project, the ease of use, plethora of options and great langauages models makes this a must have. despite lots of captioning services out there, this one wins it all, very very simple and intuitive controls, highly detailed and great results. and I cannot forget the dev. help and support (even in free version). thank you for that."
