Xook — your personal AI coach
A BYOK coach grounded in your own course, progress and reflections — powered by your own free key.
- A coach that actually knows where you are — your chapter, your journal, your weak spots
- Runs on your own free API key, so it's yours and effectively unlimited
- Automatic failover across your key chain (personal → org → platform where entitled)
- A device-only mode where your key never leaves your browser
A coach, not a generic chatbot
Xook is your personal AI coach. Every answer is grounded in your context: your course content (retrieved on the fly), how far you've progressed, the open questions you wrote in your own journal, your engagement patterns, and durable mentor memory — stable facts Xook has learned about your goals and weak spots across sessions. The style is warm, Socratic and concrete: real production systems, real costs, what breaks when it's done badly.
Good openers: "What should I focus on today, given where I am?", "Quiz me on what I learned this week.", "What did I get wrong recently that I should revisit?"
Bring your own key (BYOK)
Xook runs on a key chain, tried in order with automatic failover:
1. Your personal key — free to get from NVIDIA NIM, Groq, Gemini, OpenRouter and others; add it in Settings → Xook AI keys
2. Your org's shared key — if your organization has enabled sharing
3. A platform key — where your tenant has that entitlement
The coach page detects whether any usable key exists and, if not, shows a banner walking you to Settings. Replies stream in, and each one shows which provider and key answered, so failover is never a mystery. Key material itself never reaches your browser in the standard mode.
Device-only mode
Prefer that your key never touch miatz servers at all? Device-only mode stores the key in your browser: Miatz supplies the grounding context, and your browser calls the provider directly. One caveat — some providers block browser-side calls (CORS). If that happens, switch to a server-vault key, or use a CORS-friendly provider like OpenRouter or Google AI Studio.

The journey, step by step
| Step | What you do | What you get |
|---|---|---|
| Add a key | Connect a free API key in Settings → Xook AI keys (NVIDIA NIM, Groq, Gemini and more) | Xook lights up — the page detects a usable personal or shared-org key |
| Ask something real | Try a starter like "What should I focus on today, given where I am?" | A streamed answer grounded in your course, progress and reflections |
| Go deeper | Ask it to explain your current chapter, quiz you, or revisit recent mistakes | Socratic, concrete coaching tied to real production systems |
| Check the source | Glance at the provider tag on the reply | You always see which key in your chain answered |
Frequently asked
Why does Xook ask me for an API key?
Xook is BYOK — bring your own key. It runs on your personal key, your org's shared key if your org enables sharing, or a platform key where your tenant is entitled. If none of those exist, the chat prompts you to add a free key in Settings → Xook AI keys.
How is Xook different from the AI Tutor?
The AI Tutor answers course questions on the platform's AI with subject-expert personas. Xook is your personal coach on your own keys: grounded in your progress, journal and engagement, with durable memory about you across sessions.
What does Xook actually know about me?
Your course content (via retrieval), your recent progress and journal open questions, your engagement patterns, and durable mentor memory — stable facts learned about your goals and weak spots. It uses these to tailor every answer.
What is device-only mode?
A privacy option where your key is stored only in your browser and never touches miatz servers: the app fetches grounding context, then your browser calls the provider directly. Note some providers block browser calls (CORS) — OpenRouter and Google AI Studio are reliable choices there.
