Question 1

How does the AI Typing Coach work?

Accepted Answer

The AI Coach analyzes your last 40 typing sessions to build an 8-category Typing DNA profile (speed, accuracy, consistency, punctuation, numbers, capitals, transitions, endurance), an error heatmap across the QWERTY layout, and a list of weak bigrams. It then generates personalized priority drills targeting your lowest-scoring dimensions.

Question 2

Do I need to sign in to use the AI Coach?

Accepted Answer

The dashboard works for guests using local session history. AI-powered custom drill generation (LLM-backed personalized topics) requires a free sign-in.

Question 3

What is Typing DNA?

Accepted Answer

Typing DNA is an 8-pillar score that breaks down your typing across speed, accuracy, consistency, punctuation handling, number row, capitalization, key transitions, and endurance. Each pillar is scored 0–100 with strong/average/weak levels.

Question 4

Can the AI Coach generate custom drills on any topic?

Accepted Answer

Yes. Signed-in users can request custom drills on any topic — for example 'semicolons', 'phone numbers', 'JavaScript async/await', or 'medical terminology'. The system generates a 60-second targeted practice session.

Question 5

How long until I see improvement?

Accepted Answer

Most users see measurable improvement in their weakest dimension within 2–3 focused drill sessions. The AI Coach tracks your 7-day trend and recommends the next best session based on your current rate of change.
