TypeFocus
A typing-biometric focus coach for remote workers and students that watches keystroke cadence and pause patterns throughout the workday, surfaces a real-time cognitive-fatigue score, and prescribes targeted micro-breaks or task switches before burnout.
Knowledge workers, grad students and remote employees who sit in long deep-work blocks
- Passive fatigue scoring from typing cadence, deletion rates and idle gaps — no wearable or webcam required
- Adaptive break prescriptions (breathing, walk, context-switch) tuned to your current fatigue band
- Weekly cognitive-rhythm report showing your sharpest hours and which meeting days tank your typing fluency
- Team-mode for managers that anonymizes and aggregates focus signals without ever reading message content
A YC W26 neuroscience+AI startup is hiring to build exactly this kind of behavioral inference, and the parallel ACL paper (ExPerT) just proved keystroke dynamics can carry real cognitive signal — consumer focus tools currently rely on screen-time, not cognition.
Multiple 2025 papers (AIJFR, IJCRT, IEEE, FlowState GitHub) prove keystroke-dynamics fatigue detection is academically active with ROC-AUC ~0.85, but no consumer-product evidence of pull for a typing-biometric coach specifically.Keystroke Pattern Analysis for Cognitive Fatigue Prediction ↗GitHub - charu2210/FlowState: Non-Invasive Cognitive Load Estimation ↗
No commercial consumer app in search results does keystroke-cadence-based fatigue scoring; RescueTime/Focusmate/Forest-style tools track time or block distractions but do not infer cognition from typing, leaving the niche open.Best Focus Apps for Remote Workers in 2026 ↗Simple plans.

Proven $9–15/mo subscription willingness for focus tools (RescueTime ~$9/mo, Focusmate Plus tier) but the biometric-fatigue angle has no validated willingness to pay and may need a B2B/employer channel to clear privacy friction.RescueTime Pricing 2026 ↗Pricing - Focusmate ↗
Hybrid work and passive wellbeing sensing are durable tailwinds, but keystroke surveillance sits in the same cultural backlash zone as employee monitoring tools, which caps upside and adds regulatory risk (EU AI Act, US state wiretap laws).Best Focus Apps for Remote Workers in 2026 ↗
Pure-software build with demonstrated ML baselines; main friction is cross-platform keyboard-hook reliability (Mac/Windows/Linux/ChromeOS) and the need to keep inference on-device to avoid privacy blowback.GitHub - charu2210/FlowState: Non-Invasive Cognitive Load Estimation ↗
