Local-First Tools Are Quietly Eating the Web

For twenty years, the deal with free web tools was simple: you give them your file, they give you a result (and maybe keep your data). WebAssembly, WebGPU, and small open models have quietly broken that trade. The heavy lifting moved into the tab.

What runs locally now

• ✦Speech-to-text with OpenAI's Whisper, compiled to run on your CPU/GPU in-browser.
• ✦AI background removal with segmentation models like U2Net.
• ✦OCR with Tesseract — screenshots to text in seconds.
• ✦Full video processing with ffmpeg.wasm: extract audio, grab frames, remove watermarks.

The incentives finally line up

Local-first is better for users (privacy, speed, no accounts) and better for builders (no storage costs, no GDPR liability for uploaded files, no abuse moderation of stored content). When incentives align like that, the shift tends to stick.

That's the bet behind Starlight Tools: a growing shelf of pretty, fast, genuinely free tools where your files never leave your device. The anime aesthetic is the bow on top ✦
