Not another wrapper around a spinner

Most online tool sites upload your file, show you an ad, and make you wait. This one doesn't.

Processing stays on your machine

JSON, code, and regex tools run entirely client-side. Nothing you paste is ever uploaded — safe for API keys, internal payloads, anything sensitive.

AI that reviews, not just formats

Claude is built into the toolkit for code explanation, review and refactors — not bolted on as a chatbot sidebar.

Built for keyboard, not mouse

⌘K jumps to any tool instantly. Every action has a shortcut. No hunting through menus to get work done.

No ads, no dark patterns

Free tier is actually free. No countdown timers before your download, no upsell popups mid-task.
