EST. 2025RIMFACTORY · AI SERVICES & DATA
We operate SajuAstrology, a divination service in 10 languages built on a saju-reading deduction engine. We are also developing RimSaju cafés and kiosks and PrephysicalAI data for robot learning. Ultimately, Rimfactory turns the messy real world into operators and builds a symbolic AI deduction engine that cuts both GPU compute and the data HBM has to move.

02Our approach
Sources
We link Saju interpretations to the classical texts they draw on, so readers can review their sources.
Calculation
We account for birth time and location, keeping chart calculations separate from generated interpretations.
Quality
For robot learning data, we define recording conditions and review criteria, then evaluate sample recordings.
Documentation
Our papers and research notes document methods and evaluation. We distinguish live services from work in development.
03PREPHYSICALAI · ROBOT DATA TECHNOLOGY
Prephysical Studio is our own tool for aligning multiple camera views, reconstructing hand motion, retargeting it to robot models, and exporting data with review records. It is being built to turn household actions recorded in varied homes into inspectable research data.
CAPTURE → STUDIO → ROBOT
Data capture technology · Korean patent application filed Sep 21, 2026
These product screens and playback use Studio’s built-in synthetic demo. 3D accuracy on real home recordings and robot-learning value have not yet been validated. Studio 2.0 for Windows is in early access.

Brand mark
Our mark puts what we do into a single shape: rebuilding the structure of an old divination tradition as data.
The open rim RIM
The “rim” in Rimfactory. It is left open on one side — a system that is never closed, an orbit that keeps expanding.
Four pillars FOUR PILLARS
The year, month, day and hour pillars of Saju (四柱). Bars of different heights that also read as a data chart.
A star on the orbit STAR
A gold star where the rim opens — the sign of divination, and our direction as the world’s first high-tech divination company.
Cobalt #1537E6 · White · Gold #F2C14E, used only for the star
