Vault test builder
Emails, client-safe tone, meeting subtext, deadlines, and business collocations. The generated prompt bank is now a product surface: choose an angle, pick source-language traps, and review a draft test that can become a funnel, challenge, or catalog diagnostic.
Product angles
Pick the hook first. The builder keeps the same 12k database underneath, but changes the question families and preferred mechanics.
Useful for a hook like: ready for internal meetings, but not client-facing yet?

Business-ready
Emails, client-safe tone, meeting subtext, deadlines, and business collocations.
Speak better
Minimal pairs, read-aloud prompts, fast speech, and practical spoken responses.
Exam pressure
Academic reading, listening, writing, inference, and task-rubric prompts.
Travel survival
