Small ideas.
Useful creations.

AI tools and MCP servers multiply faster than anyone can follow. New names appear daily, scattered across GitHub and newsletters, and picking the right one means chasing links instead of making progress.

100Ideas AI

We built a structured directory that catalogs open-source AI tools and MCP servers with clear categories, descriptions and links. It is a living archive — updated as the ecosystem grows — designed to be skimmed in minutes, not studied in hours.

The calculations people actually live by — how many Schengen days are left, how close FIRE is, how many calories a body burns — live in cluttered sites full of ads and sign-up walls. The answer is buried under the noise.

CalcAtlas

We built CalcAtlas as a small atlas of calculators — Schengen 90/180 tracking, FIRE planning and TDEE — all running locally in the browser, with instant results and zero uploads. Each one is one screen, one answer, done.

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.

PDF

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.

Every "free" image compressor uploads your files somewhere, shows ads, or caps you after two images. Photographers and web builders end up choosing between privacy and a usable tool.

Image

We built a browser-based compressor that processes JPG and PNG entirely on your device. Drop a file, pick a quality, download the result — nothing is uploaded, no account exists, and the compression happens in the time it takes to blink.

Markdown is the writer's best friend until it's time to export. Converters mangle formatting, editors force you into their workflow, and getting a clean, print-ready PDF usually means fighting a tool instead of finishing a document.

Markdown Studio

We built Markdown Studio as a split workspace: Markdown input on the left, live A4 preview on the right, styled for print from the start. Export is a single click, everything runs in the browser, and nothing you write ever leaves your device.

Model kit builders juggle spreadsheets, photo folders and half-remembered shelf spots. The backlog grows, WIP photos scatter, and a collection that should feel like a showcase feels like chaos.

Gunpla Log

We built Gunpla Log as a builder's companion for iOS with a web landing: log every kit, track build progress, attach photos and organize the collection the way it deserves. It turns a spreadsheet chore into a showcase you actually want to open.
