SENSATION BEFORE EMOTION
Want to understand all sixteen territories?
THREE STEPS
Check in with your body
Tap where you notice sensation. Name its quality. Notice its intensity.
Practice what your nervous system needs
Adaptive somatic practices respond to your data — not a script.
Watch your patterns emerge
Over days and weeks, see what your nervous system has been running.
Your chest tightens before meetings. Your jaw clenches around certain people. Your energy drops every Sunday evening. These aren't random — they're predictions your nervous system learned to make. Cathexis helps you read them.
BRAIN · BODY · WORLD
Three views of one nervous system.
Brain — Which networks activate, and when.
Body — Where your sensations concentrate over time.
World — The people, places, and pressures that shape what you feel.
PROGRAMS
Nine 30-day therapeutic programs.
Each addresses a specific pattern your nervous system learned to run.
| Living with Threat | Living with Shutdown | Living with Loss |
| Anxiety, hypervigilance, panic | Low mood, numbness, fatigue | Grief, yearning, hollowness |
| For Those Who Feel Too Much | Living Under Siege | Living with Conflict |
| Flooding, overwhelm | When the past keeps arriving | Torn between opposing truths |
| Living in the Body Under Strain | Living Under Pressure | Navigating Change |
| Chronic pain, body image | Burnout, chronic stress | Identity shifts, life transitions |
Six learning levels per program — from guided awareness to independent practice.

ON-DEVICE INTELLIGENCE
Your data stays on your phone. Your intelligence stays personal.
Cathexis uses Apple's on-device AI to generate observations grounded entirely in your own patterns. Ask your somatic field a question by voice or text. Receive an answer built from your check-ins, your practices, your body — not a generic chatbot response.
Morning predictions. Evening check-backs. Observations that surface what you haven't noticed yet.
Nothing is uploaded. Nothing is shared. The AI runs on your iPhone.
BUILT FOR YOUR PROVIDER
Everything your therapist wishes you had between sessions.
A Session Report PDF captures your check-ins, somatic shifts, regulation patterns, and ecological context in clinical language — ready for any provider.
A Treatment Plan that updates as your nervous system changes.
My Story builds a portrait of your experience over time.
