What we ship today,
and what we're building next.
Products operated and built by Rojiura Studio. Each one is shaped together with AI agents — small lanterns for daily work.
A lantern in every alleyway.
The studio's brand LP and portfolio rolled into one site — built almost end-to-end with multiple AI coding agents (Claude Code, Codex, Gemini). A live showcase of how we work.

A family app that connects home stock, shopping, and packing.
An inventory app developed and improved with AI after testing a no-code MVP with users. The iOS app launched in July 2026, bringing together concept development, validation, implementation, and App Store delivery.

Never lose track of the next task — a calendar-driven home-garden app.
PRD, architecture, and sprint plans live in docs; each sprint shipped as a PR mostly written by AI agents. Humans held the line at PRD-level intent and PR review, while AI did the bulk of the implementation — a doc-driven, AI-native build loop. Currently shipping iOS only.
Stack
Every trace you leave with your car.
A two-surface product: a Flutter app and a Next.js web app sharing the same Supabase backend. Repos are separated, but the PRD and data model live in a shared docs space so AI agents can move between both surfaces without losing coherence.
Stack
Pitch reference for early music.
A pitch-reference app for early-music and Baroque performers, supporting historical pitches (A=392 / 415 / 430 / 442 / 466 Hz) and classical temperaments (¼-comma meantone, Werckmeister III, Kirnberger III, just intonation). Harpsichord, grand-piano, and violin timbres plus a drone make pre-ensemble tuning quick. Built with React Native + Expo, currently available on the iOS App Store.
