A marketplace for small, sharp utilities.

Twenty-four tools across PDF, image, text, AI and developer workflows — each one a focused module inside a single, consistent product surface. New tools ship roughly every week.

02b — Live demo

Every tool has the same shape.

Input · operation · output. AI is an optional layer on top — same interface, quieter posture. This isn't a screenshot; type into the box.

03 — AI Layer

AI as a quiet upgrade, not a separate product.

Every tool has an AI mode. Same input, same output, same shape — just sharper results. No new interface to learn, no “chat with my PDF” trope. Toggle it on, toggle it off.

04 — Ecosystem

A platform, built in public, one module at a time.

Four systems. Twenty-four modules shipped. A roadmap that's visible and honest — what's live, what's wet paint, what's queued. Nothing here is handwaved.
