Rhythm
The pattern of good care
The daily, reliable pattern of good care. Breakfast at the same hour. Medications at the right moment. The steady arrival of someone trusted.
Our story
We shipped AI summarization in 2020. Now we ship agents for care.
A small team, modern AI, and GK Cares — the home care agency we're launching on Rithma.
plex.page → Rithma
Five years ahead of the curve
Osman and Khasan Musabaev built plex.page before ChatGPT existed. That work became Rithma — agents that act, not just chat.
GK Cares
Our family's agency — built on Rithma from day one
We're launching GK Cares — our family's California home care agency — on Rithma from the first shift.
We feel what caregivers feel and see what agency owners see. When something doesn't work for us, we fix it before you feel it.
Why we call it Rithma
Two ideas, one word.
Rithma is both — the rhythm of daily care, made intelligent by algorithms.
Algorithm
The intelligence behind the work
From Al-Khwarizmi, the 9th-century mathematician we inherit the very idea of systematic computation from. The algorithms behind every modern AI agent trace back to his work.
Rithma · noun— A care platform that listens, remembers, and acts, so that nobody who needs help goes unseen.
