Power Mysty with your own free AI key (BYOK)

What is Mysty?

Mysty is your personal AI coach. It's grounded in your world — your course content, your cohort, your reflections and your live progress — so its answers are about where you actually are, not generic.

Mysty runs on an AI key. On the free plan you bring your own (BYOK) — every provider below has a free tier, no credit card needed.

Add a key (2 minutes)

1. Go to Settings → Mysty AI keys.

2. Pick a provider and open its “How to get a free key” guide.

3. Follow the steps to generate a key, paste it in, choose a model, and click Validate & add key. We test the key before saving it.

Recommended free providers

• NVIDIA NIM (build.nvidia.com) — free credits, generous limits. Keys start with nvapi-.
• Groq — very fast, free daily tokens. Keys start with gsk_.
• Google AI Studio (Gemini) — free tier, no card. Keys start with AIza.
• OpenRouter — use any model tagged :free. Keys start with sk-or-.
• Cerebras, Together, Mistral — all have free tiers too.
• Custom — any OpenAI-compatible endpoint (bring your own base URL + key).

Automatic failover

Add more than one key and Mysty tries them in precedence order (lower number = tried first). If a key fails or times out, Mysty automatically fails over to the next one — so a rate limit on one provider never stops you. Reorder precedence anytime on the same page; disable or delete a key with one click.

Is my key safe?

Yes. Your key is validated, then encrypted into a server-side vault. It never appears in the browser again (you only ever see the last 4 characters), it's never returned in any API response, and a database dump alone can't reveal it. If your organization adds shared keys for the whole cohort, members use them through the server without ever seeing the key.

Tiers

• Basic — your own free key (this page).
• Advanced — tools, planning and memory.
• Cloud — your organization runs Mysty for the whole cohort on shared keys.
• DemystiPai — the hosted top tier.
