Vector measures your focus capacity, diagnoses what breaks it, and adapts your training — session by session.
Built on decades of research in deliberate practice, flow psychology, and cognitive load — implemented as a living system.
Zero-knowledge. Local-first. Your data never leaves your device.
Background sounds don't train your ability to sustain attention. They're just masking noise.
Pomodoro timers assume you can already focus. They don't adapt to your actual capacity.
Meditation apps help you unwind, but they don't build the specific skill of deep work.
In science and mathematics, a vector has both magnitude and direction.
Effort alone isn't enough. Focus only improves when effort is applied in the right direction, at the right load, with feedback.
Vector doesn't just ask you to try harder. It helps you aim better — then adjusts your trajectory over time.
Most experts explain what to do.
Vector helps you do it — by measuring your focus capacity and adapting your training session by session.
You've heard the ideas. Vector turns them into a system you can actually follow.
| Expert | What they teach | Where people get stuck | How Vector helps |
|---|---|---|---|
| Cal Newport (Deep Work) | "Deep work needs structure" | Hard to sustain consistently | Builds sessions around what you can actually sustain |
| Anders Ericsson (Deliberate Practice) | "Skills improve with practice + feedback" | No coach, no progression | Acts like a focus coach with feedback after each block |
| Mihaly Csikszentmihalyi (Flow) | "Challenge must match skill" | Flow is hard to trigger | Adjusts difficulty so work isn't overwhelming |
| Nir Eyal (Indistractable) | "Distraction comes from triggers" | Forgetting techniques in the moment | Detects patterns and responds automatically |
| Andrew Huberman (Neuroscience) | "Focus depends on energy & biology" | Generic protocols don't fit your day | Adapts to fatigue instead of pushing harder |
Experts explain focus. Vector trains it.
A closed-loop system that measures, diagnoses, adapts, and learns — so focus improves over time.
Private by design. Your focus data stays encrypted on your device.
Measure focus capacity → diagnose limiters → adapt training session-by-session.
Vector establishes your true focus capacity using a structured baseline assessment: progressive focus blocks that reveal when attention starts slipping and what triggers the decline.
Calibrated for cognitive load, not willpower.
Each block includes rapid reflection to identify failure triggers — whether it's urge to switch, confusion, or fatigue. Vector builds a profile of what limits your focus.
Not just timing. Pattern recognition.
Vector adjusts block length, break type, and coaching prompts based on your last performance. Each session trains at the right load for your current capacity.
Like strength training, but for attention.
Watch your baseline focus capacity increase over time. Vector shows not just what you did — but how your sustainable attention threshold is changing.
Vector doesn't help you focus once. It trains you to focus better — permanently.
It's the foundation.
Your focus data is encrypted on your device. Vector cannot read your goals, notes, or reflections.
Coaching, baselines, and trends are computed locally — not on our servers.
Export or delete your data anytime. No lock-in. No hidden copies.
