Stride
AI-powered focus companion
The premise of Stride is simple: most focus tools tell you to work, but they don't actually help you stay in it. Stride sits with you during a session, watches how things are going, and steps in with an AI-driven nudge exactly when you're starting to drift.
Key decisions
The intervention engine
A Claude-powered system generates contextual nudges during focus sessions. I layered the Opik SDK on top for observability: tracking every intervention, scoring them with LLM-as-judge, and A/B testing message variants to learn what actually pulls people back into focus.
Solving activation before retention
Early data showed users dropping off before they felt the product work. I shipped a first-session overlay and a demo intervention so new users get the AI nudge in their very first session.
