Hi Product Hunt! 👋 I'm the solo developer behind Thumb3D.
I was frustrated with paying 15−20/month for cloud-based design tools just to remove a background or create a decent 3D text effect for videos. So, I decided to build a solution.
Thumb3D is a browser-based creator toolkit. The secret sauce? It runs entirely on Local AI using WebAssembly and WebGL.
✨ Core Features:
Local AI Background Remover: Because it runs on your device's hardware, I have $0 server costs. That means it's 100% free, watermark-free, and your images are never uploaded to any cloud (absolute privacy).
Cinematic 3D Typography: Render glowing, metallic, and neon 3D fonts right in the browser.
AI Video-to-Shorts: Crop landscape videos to 9:16 and auto-generate karaoke subtitles using local Whisper AI and FFmpeg.
Local OCR (Image-to-Text): Extract text instantly.
I built this to disrupt the subscription fatigue in the creator economy.
I would absolutely love to hear your feedback, thoughts, or feature requests! Let me know what you think. ❤️
