Hi, I'm AJ.

I build little things for the internet. Some are meant to be genuinely useful, and they do their job right in your browser without handing your stuff to a random server. Some are a cursed hamster that reacts to your hand gestures. Both feel worth making.

Why this exists

Every time I needed a simple tool online, I'd find one buried under sign-up walls, upload limits, watermarks and “upgrade to Pro” pop-ups. So I started building my own and putting them here, for free, for everyone.

The rules I build by

• Free, for real. No trials, no paywalls. Ads keep the site running.
• Private by default. Wherever possible, tools run entirely in your browser. Your webcam feed, files and images stay on your device.
• No accounts. You'll never need to sign up for anything here.
• Fast. Tools should load instantly and work on your phone too.

Got an idea?

If there's a tool you wish existed (or one of mine is broken), tell me. The best ideas usually come from people who are annoyed at something.
