“We believe documents should get out of the way — not add a second job on top of the one you are already doing.”
Why we built it
The problem
Every PDF tool asks you to learn its panels, sign up for its account, and wade through its ads before you can do the one thing you opened it for. People spend more time fighting the tool than finishing the document.
The idea
The creation
We built a single quiet browser workspace where merge, split, compress and convert sit one glance away. Everything runs in place, files stay local, and the interface recedes so the document becomes the interface. The whole product fits on one screen because the job usually does.
This creation began as #003 in our idea archive.
Observation
Every PDF tool felt like a second job.
Idea
No panels, no accounts — just documents.
Creation
One screen, files stay local, done in seconds.

Most PDF tools are cluttered suites. PDF is a single quiet workspace: one screen, local-first, and every task finishes in seconds.
Started as #003 — PDF
A simple way to work with documents.
Free, instant, privacy-first calculators — Schengen, FIRE and TDEE.
“We asked: what if the most useful calculators lived in one clean, instant, private place? No accounts, no tracking, just the number you needed thirty seconds ago. That is why we made this.”
Compress JPG and PNG images online — processed locally.
“We asked: why should compressing an image require uploading it anywhere? The browser can do this locally — so why not build a compressor that never sees the network at all? That is why we made this.”
Explore AI models through a simple interface.
“We asked: why should comparing AI models require code? We wanted a place where a creator could put the same question to several models and feel the difference in their answers. That is why we made this.”
