The product principle
Measure enough to make the next action obvious. Every result should identify a bottleneck, explain the evidence, and offer a relevant workout.
Local-first by design
The trainer, generator, metrics, history, heatmaps, and recommendations run in the browser. An account is not required to receive the core value.
Built for real keyboard tasks
Work modes use original and synthetic content instead of asking people to upload private emails, tickets, code, contracts, or records.
A focused business model
The free product can be supported by restrained advertising outside the typing surface. Advertising remains disabled until valid deployment identifiers and consent requirements are configured.
