Adaptive practice without artificial intelligence
When recent same-device results provide sufficiently sampled weak keys, a local index scores more than a thousand useful words by target letters, common bigrams, and difficulty. The deterministic generator places them into readable original sentence patterns and progresses toward longer words and punctuation. No text or typing history is sent to a remote service.
Before and after without invented gains
After weak-key practice, KeyVelocity compares previous weak-key accuracy with the current session only when both contain enough relevant attempts. Until then, the result says it is collecting comparison data rather than inventing an improvement percentage.
Choose the right practice mode
Use Weak Keys after a full test, Accuracy Focus when errors break your rhythm, Punctuation for symbol control, Numbers for mixed records, and Long-form for endurance. Roman Urdu is available as a substantial local corpus rather than an indexable doorway page.
