Memory.fit vs TriDot
Memory.fit vs TriDot: their triathlon AI, or yours.
TriDot is an AI powered triathlon training platform from Predictive Fitness, built on its FitLogic engine and years of athlete data, with plans from $14.99 to $99 a month and a coached tier. Memory.fit has no training engine of its own: it gives the AI you already use your training, sleep, body and fuel, and your AI writes the swim, bike and run plan, daily targets and session fueling back into the Memory.fit app and onto your watch.

The difference
Where Memory.fit is different.
The AI you already use
Claude, ChatGPT, Gemini, Grok Bot or another AI plans your weeks and you can ask it anything about them. TriDot plans inside its own platform, with an in app assistant for questions about your training.
Fueling built in
Your AI can write carbs, fluid and sodium per hour for every long session, set daily fuel targets and plan race day. TriDot's pages point to an integration with Fuelin for nutrition.
Recovery, fuel and body in one place
Sleep, HRV and resting heart rate from your watch, Oura or WHOOP, weight from a Withings scale, and the meals your AI logged all sit next to the plan.
One price, any distance
$9 a month or $69 a year, 7 days free, whether you train for a sprint or a full distance race. Every AI you connect gets the same data and tools.
Fair is fair
Where TriDot is strong.
- Purpose built for triathlon, from sprint to IRONMAN distance, with strength sessions on its Complete plan.

- EnviroNorm adjusts training for heat and altitude, and RaceX builds race day pacing plans.
