Opt-in 'Weakness Drill' mode

[rono-zeroseven]

The Problem: Users want to target their specific typing weaknesses, but static word lists don't adapt to individual error patterns.

The Solution: An opt-in "Weakness Drill" mode that analyzes the current session's mistakes and uses the Gemini API to generate a custom practice list.

The Architecture: This would be a frontend-only feature using a Bring Your Own Key (BYOK) model. The user provides their own Gemini API key, which is stored locally in their browser. MonkeyType servers incur zero cost, zero infrastructure burden, and never see the user's typing data, preserving our privacy-first ethos.
How will this work: User enables feature in settings -> pastes key -> after a test, a "Generate Weakness Drill" button appears -> frontend sends only the mistyped words to Gemini -> new test starts with those words.

Would the maintainers be open to a PR for this feature? I am happy to draft the detailed technical spec and UI mockups.

You can use practice words on the end of the test to practice missed and slow words.

frontend sends only the mistyped words to Gemini -> new test starts with those words.

you don't need AI for that

I used the native 'practice missed words' feature and it's fantastic for immediate correction. The specific gap I was hoping to address is pattern generalization. The native feature repeats the exact words I missed. An AI powered mode could analyze those mistakes to identify the underlying mechanical pattern (e.g., consistently stumbling on 'ie' vs 'ei', double consonants or specific finger rolls) and generate a new set of practice words that target that specific weakness, rather than just repeating the same failed words
