TestO's tutor already works without a key. If you add your own OpenRouter key, tutor questions and voice dictation have no daily limit and are billed to your OpenRouter account, not TestO.
Create a key at openrouter.ai/keys, set a spend limit, and paste it here.
No personal key — you use the tutor included in your plan.
The key is stored only in this browser and sent encrypted (HTTPS) with each question. TestO never stores it on its servers.
