This guide shows how to connect ChatGPT in MetaLensAI using your OpenAI API key. Follow the steps once, save the key, and start voice conversations directly from your glasses.

← Back Installation and setup Gemini setup Grok setup

Estimated setup time: 2-3 minutes.

Step 1 - Generate your OpenAI API key

Sign in to your OpenAI account and create a secret API key. This key is required for ChatGPT conversations and picture analysis in MetaLensAI.

Open OpenAI API keys.
Click Create new secret key.
Copy the new key and keep it ready for the next step.

Important: Do not share your API key publicly. Treat it like a password.

If you cannot find it, use this guide: Where do I find my OpenAI API key?

Step 2 - Add the key in MetaLensAI

Open MetaLensAI on your Android phone.
Go to Settings / AI Settings.
Tap the OpenAI API key button.
Paste your key into the OpenAI API key input field and save changes.
Tap Check Connection button. If Connection OK, your access key is valid.

If validation fails, or after moving to Live Vision AI, Conversations or Picture Analysis you see error:

You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors

TLDR; It means that you need to upgrade to a paid plan. Set up a paid account, add a credit or debit card, and generate a new API key if your old one was generated before the upgrade.

Solution: Buy more credits or learn how to increase your limits.

Just a quick clarification 😅 you pay OpenAI for the ChatGPT platform, not me.

Step 3 - Start ChatGPT conversation

Go back to the Home screen in MetaLensAI.
Click Live Vision AI if you want real-time insights from what you see through glasses.
Tap Start Conversation to launch voice chat.
Use Picture Analysis if you want AI to describe what your glasses camera sees.

Need a full onboarding path first? See Installation and setup. If you hit issues, check the FAQ.
