Setting up API keys
Where to get a key for Google, OpenAI, fal.ai and Anthropic, and how to add them to the app.
Monet does not resell image generation. You bring a key from each service you want to use, and requests are billed to you by that service. Keys live in Settings → API Keys, are stored locally on your Mac, and are only ever used to authenticate requests to the service they belong to.
You need at least one of Google, OpenAI or fal.ai. Add more later at any time; each key simply unlocks its own models.
| Key | Unlocks | Where to get it |
|---|---|---|
| Google Gemini | Nanobanana Pro and Nanobanana 2 | aistudio.google.com/app/apikey |
| OpenAI | GPT Image 2 and GPT Image 1.5 | platform.openai.com/api-keys |
| fal.ai | Seedream 5.0 Pro | fal.ai/dashboard/keys |
| Anthropic | Chat orchestration (optional) | console.anthropic.com/settings/keys |
Step by step
- Google Gemini. Open aistudio.google.com/app/apikey and sign in. Sign in with your Google account, choose Create API key, and copy it. Paste it into Settings → API Keys and choose Save Keys.
- OpenAI. Open platform.openai.com/api-keys and sign in. Choose Create new secret key and copy it straight away, because OpenAI shows it only once. The account also needs billing set up. Paste it into Settings → API Keys and choose Save Keys.
- fal.ai. Open fal.ai/dashboard/keys and sign in. Create a key in the fal.ai dashboard and copy it. Paste it into Settings → API Keys and choose Save Keys.
- Anthropic. Open console.anthropic.com/settings/keys and sign in. Choose Create Key and copy it. Only needed if you want Claude deciding what Chat does; Google or OpenAI can handle that instead. Paste it into Settings → API Keys and choose Save Keys.
Background removal is the one feature that needs no key at all. It runs locally on your Mac, so it works offline and costs nothing per image.
