Sorted the way you think.

Four working categories today, with PDF, image, AI and team tools planned.

How it works

Your data should stay yours.

Every tool available today does its work in your browser. You paste something in, your device does the processing, and the result appears — no upload, nothing to store, nothing to leak.

It is also simply faster. There is no round trip to wait for, so the output updates as quickly as you can type.

Some jobs genuinely need a server — very large files, or features that cannot run locally. Every tool states how it processes data through its processing mode, and that badge is generated from the same field the tool runs on, so it cannot fall out of step.

No network request carries your input on a browser-based tool. You can confirm it in your browser’s network inspector.

Approach

Small tools.
Serious work.

Most of the day-to-day annoyances in building things are small ones: a payload that needs reading, an expression that needs testing, a number that needs checking. They deserve a sharp tool, not a platform.

One job each
A tool that does one thing needs no onboarding, no settings page and no documentation. You already know how to use it.
No ceremony
No account, no modal, no tour, no cookie wall before you can paste something in. Open it, use it, close the tab.
Built to last
Plain, fast pages that load on a bad connection and still work in two years. Nothing here depends on a trend.

Collection

One toolbox. Every small job.

17 tools across 3 categories, every one ready to use. Everything lives in one place, so you stop hunting for whichever site did the thing last time.
