Questions & Answers

As answered by people managing utilz and StackFlow Tools.

What makes your product unique?

utilz's answer

Every tool runs inside your browser, so files are never uploaded to a server. That includes the AI tools: background removal, upscaling, transcription and text to speech all run on your own device. You also don't need to sign-up, everything is completely free and there is no daily limit.

Why should a person choose your product over its competitors?

utilz's answer

Most free tool sites upload your files, cap how much you can do per day, add watermarks or push a paid plan. utilz does the same jobs for free with none of that, and because files stay on your device it's safe for private documents and photos. It also covers far more than one category, so PDFs, images, audio, video, conversions and calculations are all on one site.

How would you describe the primary audience of your product?

utilz's answer

Anyone who needs a quick task done without installing software or creating an account: students and teachers, office workers handling PDFs, people editing photos for online listings or social media, developers who need a formatter or converter, and anyone who cares about keeping their files private.

What's the story behind your product?

utilz's answer

Most free tool sites make you upload your files, sign up, or wait through ads and daily limits for something a browser can do by itself. I wanted one place where every tool just works on the spot, keeps files on your own device, and is free without a catch.

Which are the primary technologies used for building your product?

utilz's answer

  • Astro and TypeScript, hosted on Cloudflare Pages
  • pdf-lib and PDF.js for PDFs
  • Mediabunny for audio and video
  • Transformers.js with open models (Whisper, Kokoro) for the AI tools
  • Tesseract.js for OCR
  • Stockfish for chess

Everything runs in the browser with WebAssembly and JavaScript.
