01
All the calendars, one door. School, work, and hobbies for one household. Google and Outlook can sit on the same board, read-only.
02
Plan the week’s meals. Mon–Sun on the door, a cook name on tonight. Menus scale the shopping list to the guests.
03
Cook from the fridge. A photo of the shelf, or the ingredients you name. One recipe card, and only the missing items on the list.
04
Say it, or photograph it. FrinAI takes a voice note or a school flyer. Kids can be in the household without an email.

03 — Stack guide

The stack that fits.

A guide, not a directory.

Describe the job. FitStack lines up a stack you can start today. It starts from the work, the machine you have, and whether the data may leave the building.

01
Two or three ways through. The easy cloud path, a builder-in-the-middle, and a local stack when the hardware can carry it.
02
The steps stay with their authors. FitStack does not keep its own install tutorials. A field note is a reason to click, plus an official one-liner when the authors published one.
03
Prices are labeled honestly. Cloud rates come from OpenRouter, stamped with the date they were fetched. Street prices, local fits, and electricity are authored ballparks.

Open FitStack

Recipes belong to their authors. FitStack does not maintain the install scripts.

FitStack in dark mode. Describe the job, pick a device, and see a short stack.

04 — Field report

Speak or photograph a safety case.

Hold the button and tell us what happened.

A worker holds one button and speaks, adds up to three photos, or types a note. SafetyBot classifies the case, writes a short description, and fills only the fields the current schema asks for.

01
The worker screen. Hold to talk, add a photo, or type instead. The language picker starts at Auto-detect and includes Finnish, Arabic, and many more.
02
Then it leaves. Submitted reports go out through a webhook or GET /api/reports. SafetyBot is the capture screen, not the official record.
03
Five default case types. Injury, near miss, good practice, idea, observation.

Open SafetyBot Source on GitHub

Early preview, v0.1.7, MIT license. It is a reporting interface. It is not a medical, legal, or certified incident system.

SafetyBot. Hold to talk, add up to three photos, or type a safety case. The worker screen is light.

The studio

One name, four doors.

The products stay separate. A household kitchen. A paper trading desk. A guide for choosing a stack. A screen where a safety case can be spoken or photographed. Each one keeps its own site.
