💬 Driftline vs ChatGPT
General-purpose AI — training advice, no real data.
ChatGPT can write plans and answer questions. It has no real-time access to Garmin, Strava, or WHOOP. You must supply context every time; it does not intervene automatically when drift appears.
ChatGPT strengths
- Instant general advice
- Cheap or free tier
- Flexible chat on any topic
- Fast draft plan generation
Driftline edge
- Tied to real training data
- Automatic plan change when HRV drops
- No prompting required — writes proactively
- Endurance-specific signal reading
