Part 107 Pass - Set Up Your Free AI Tutor Key

Two quick things unlock your tutor: your access code (from your purchase email) and a free Google Gemini API key. Both take about two minutes total.

🔑 Access code: when you open the AI Tutor, paste the P107-XXXX-XXXX code from your purchase email to unlock it. Lost it? Reply to that email and we'll resend it.

🔒 Your key stays private. It's saved only in your own browser and goes straight from your device to Google. Part 107 Pass never sees or stores it.

Open Google AI Studio

Go to aistudio.google.com/app/apikey and sign in with any Google account (the same one you use for Gmail is fine).
Click “Create API key”

You'll see a blue Create API key button. Click it. If it asks you to pick or create a project, just accept the default — any project works.

💡 If you don't see the button right away, look for “Get API key” in the left menu first, then Create API key.
Copy your key

Google shows a long string that starts with AIza…. Click the copy icon next to it. That's your key — keep it handy.

⚠️ Copy the whole thing, with no extra spaces before or after it.
Paste it into the tutor

Head to the AI Tutor page. In the setup box, leave the provider on Google Gemini, paste your key, and hit Start Tutoring. That's it — you're in.

Troubleshooting

It says “Expected OAuth 2” or “invalid credentials”

Almost always a stale page. In the tutor, click ⚙ Settings → Clear saved key, then hard-refresh: Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac). Re-paste your key. If it persists, try an incognito/private window.

It says “API key not valid”

The key was likely copied with a stray space, or it came from the wrong place. Re-copy it from aistudio.google.com/app/apikey (Google AI Studio — not the Google Cloud Console) and paste again.

Is the free tier really free?

Yes — Google's Gemini free tier gives you a generous number of requests per day at no cost, which is plenty for exam study. No credit card required for the AI Studio free key.

Do I have to do this every time?

No. Your key is saved in your browser, so you only set it up once on that device. Use the same browser and you'll go straight into the tutor next time.

Can I use ChatGPT or Claude instead?

Yes. In the tutor's setup box, switch the provider to OpenAI or Anthropic and paste a key from that provider instead. (Those require a little billing credit; Gemini's free tier is the easiest start.)

Is my key or my chat shared with anyone?

No. Everything happens in your browser and goes directly to your AI provider. We never see your key or your conversations.
