Adaptive AI Coach
Your coach doesn't just talk.
It acts.
Coach Prysm detects fatigue, proposes concrete changes, and adapts your plan — in one click.
- Detects fatigue via ACWR and RPE tracking
- Proposes changes, not just advice
- Adapts your plan in one click
“Every session has a reason. Every adaptation has data behind it.”
The Prysm philosophy
Session Structure
Every session is a precise prescription
Not just 'run 45 minutes'. Every session has a warmup, work blocks with target zones, and a cooldown — like a real coach would prescribe.
Warmup
5:30–5:45/km
Work
4:35–4:45/km
Cooldown
5:45–6:00/km
After Each Session
Measure your plan adherence
After each session, PRYSM compares what was planned with what you actually did. A compliance score /100 and per-metric breakdown.
Fatigue Intelligence
Your training load, quantified
The ACWR tells you if you're in the optimal zone or at injury risk. Training paces are calculated automatically.
Strain (ACWR)
Race Time Estimator
Your predicted finish times
Updated after every session. The more you train, the sharper the prediction.
3h42 – 3h55

Based on your last 12 weeks of training
Render Engine
Under the hood.
Most apps give you a plan. Prysm gives you an engine. Every session runs through 8 layers of pure logic — volume, fatigue, readiness, pace — before it lands in your calendar.
VolumeLayer
Volume sized for your body
Every session is calculated to the right load for your week — not too much, not too little. Automatic deload weeks are built in.
FatigueLayer
Fatigue tracked, session by session
ACWR (Acute:Chronic ratio) is computed continuously. If you're overtrained, the engine pulls back before you break down.
ReadinessLayer
Bad sleep = lighter session
Sleep, HRV, and soreness are read as daily inputs. 3-day rolling averages filter single-night noise. Great signals unlock a +5% boost.
ComplianceAdaptationLayer
The plan learns from your execution
Over RPE for 14 days? Volume drops 10%. Skipping 3+ sessions a week? A forced deload triggers. Crushing it? Volume climbs.
Before. After.
