Vault test builder
Build a translated-English detector
Fast phrase traps, collocations, emotion context, scene inference, and native-sounding choices. 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.
Good for viral funnels that ask whether the learner sounds native or translated.
Level check
A mixed diagnostic from grammar, vocabulary, naturalness, listening, and real-life prompts.
Sound natural
Fast phrase traps, collocations, emotion context, scene inference, and native-sounding choices.
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
Airport, hotel, restaurant, shopping, instruction following, and object vocabulary.
