Your API Key is your private key. iXentBench reads it directly from your computer — it is never uploaded, shared or sent anywhere. Think of it like a PIN code: only you have it and only your computer uses it.

1 What is the .env file?

The .env file is a simple text file that lives in your ~/ixentbench folder. It stores your API Key so iXentBench knows which AI model to use when you play.

⚠️ It starts with a dot (.) which makes it hidden by default on Mac and Windows. Don't worry — the steps below will show you exactly how to open it.

4 How to paste your key correctly

Once you have your API Key, open your .env file and find the line for your provider. Paste your key directly after the = sign — no spaces.

❌

Wrong: GOOGLE_API_KEY= AIzaSyXXXXX
Space after = is not allowed

✅

Correct examples:
GOOGLE_API_KEY=AIzaSyXXXXX  ← Gemini (Google)
ANTHROPIC_API_KEY=sk-ant-XXXXX  ← Claude (Anthropic)
OPENAI_API_KEY=sk-XXXXX  ← GPT (OpenAI)
Only fill in the key for the model you want to use. Leave the others empty.

✅

You're all set! Your API Key is saved and iXentBench will use it automatically every time you play. You never need to type it again.
