Gemini API Integration
Integrating AI features into Pixebuilder allows you to automate text generation and create custom visuals on the fly. To enable these features, you will need to generate a Google Gemini API key.
1. Generating Your API Key
- Navigate to Google AI Studio and log in with your Google account.
- Go to the Get API key menu on the dashboard.
- Click Create API key and link it to a Google Cloud project.
- Copy the generated key, keep it private, and paste it into your PixeBuilder > Integration > AI Integration > Gemini API Key
2. Connecting a Credit Card (Required for Images & High-Volume Text)
Text generation is completely free by default and does not require a credit card as long as you stay within the generous daily limits. However, to unlock image generation or to process massive amounts of text beyond the free tier, you must link a payment method.
Steps to set up billing:
- Go to the Google Cloud Console Billing Page.
- Select Billing from the left-hand navigation menu.
- Click Manage Billing Accounts, then select Create Account (or "Add Billing Account").
- Follow the prompts to enter your country and account information.
- Add your credit card details and click Submit and Enable Billing.
- Ensure this active billing account is linked to the specific Google Cloud Project you used to generate your API key in AI Studio.
Monthly Limits:
Once you connect a billing account, Google enforces monthly spending caps to help manage costs:
Tier 1: Your API spending is capped at $250/month. If you reach this limit, your API requests will pause until the next month.
Tier 2 (Automatic Upgrade): Your limit will automatically increase to $2,000/month once you have paid at least $100 via Google Cloud (credits do not count) and 3 days have passed since your first successful payment. (Note: If you anticipate needing a higher limit immediately, you can request an override directly in Google AI Studio).
3. API Pricing & Supported Models
Google AI Studio offers a Free Tier for standard text usage and a Pay-As-You-Go tier for images and scaled production.
Text Generation Pricing (Free by Default)
Using the text writing assistant is free (no credit card needed) up to 1,500 requests per day. You only need to pay if your workflow scales up and exceeds these limits. Once on the paid tier, it is billed per 1 million tokens (roughly 750,000 words).

ChatGPT API Integration
PixeBuilder also supports OpenAI's ChatGPT as an alternative AI provider for text generation and image creation. To enable ChatGPT-powered features, you will need to generate an OpenAI API key.
1. Generating Your API Key
- Navigate to OpenAI Platform and log in or create an account.
- Go to the API Keys section in the dashboard.
- Click Create new secret key, give it a name, and copy it immediately — it will only be shown once.
- Copy the generated key, keep it private, and paste it into your PixeBuilder > Integration > AI Integration > ChatGPT API Key
2. Adding Credits (Required)
Unlike Gemini, OpenAI does not offer a meaningful free tier for API usage. You must add credits to your account before the API key will work.
- Go to OpenAI Billing.
- Click Add payment method and enter your credit card details.
- Purchase credits to get started (minimum $5).
- Usage is deducted from your credit balance as you generate text or imag
