Get Your Free Gemini API Key in 5 Minutes 🔑

Google AI Studio offers a completely free API key — no credit card, no billing setup required. This guide walks you through every step.

⏱ Takes ~5 minutes 💳 No credit card needed

Why do you need an API key?

SnapFill Pro uses AI to generate your cover letters, decode job descriptions, and draft application answers. To do this, it needs to talk to an AI model. Rather than charging you a subscription, SnapFill Pro lets you bring your own API key — meaning you connect directly to Google's Gemini AI using your own free account. Your key stays in your browser. We never see it.

Why Gemini?

Google Gemini's free tier (via AI Studio) is the most generous free AI API available today:

  • ✅ Up to 60 requests per minute
  • ✅ No credit card required to start
  • ✅ Completely free for personal/low-volume use
  • ✅ Google-grade performance for application writing

Step-by-Step Guide

01

Open Google AI Studio

Open a new tab and navigate to: aistudio.google.com — This is Google's official developer portal for Gemini AI. It's free to use with any Google account.

💡 Tip: You can use any existing Google account — the same one you use for Gmail or Drive. No new account needed.
02

Sign In

Click the 'Sign In' button and log in with your Google account. If you're already signed in to Chrome, this may happen automatically. You may be asked to agree to the Google AI Studio terms of service — accept to continue.

Find the API Keys Section

Once inside AI Studio, look at the left-hand sidebar. Click on 'Get API Key' — it is usually listed near the top or bottom of the left navigation panel. This will take you to the API key management screen.

04

Create Your API Key

On the API Keys page, click the blue 'Create API Key' button. Google will prompt you to either create the key in an existing Google Cloud project or create a new project automatically. For most users, clicking 'Create API Key in new project' is the simplest option — Google handles the project setup for you.

⚠️ Important: Once your key is generated, copy it immediately and store it somewhere safe. For security reasons, Google will not show you the full key again after you leave the page.
05

Copy the Key

Your API key will appear on screen — it will look something like: AIzaSy...XXXX (a long alphanumeric string starting with 'AIzaSy'). Click the copy icon next to it to copy it to your clipboard.

Enter Your Key and Save

In the AI Brain Settings page: (1) Set the AI Provider to 'Google Gemini'. (2) The endpoint URL will auto-fill — leave it as default. (3) Paste your copied API key into the 'API Key' field. (4) Click 'Save' or 'Test Connection'. If the key is valid, you'll see a green 'Connected ✓' status indicator.

Use these exact values in the AI Brain Settings:

API Endpoint https://generativelanguage.googleapis.com/v1beta/openai/
Model Name gemini-flash-latest

💡 Tip: SnapFill Pro also supports OpenAI, Groq, and Ollama. If you have keys for those providers, you can switch between them in the same settings panel.

Common Questions About the API Key

No — Google AI Studio's free tier is genuinely free with no billing required. You get up to 60 requests per minute and generous daily limits. For typical job application usage with SnapFill Pro, you will almost certainly never hit the limit.
Yes. SnapFill Pro stores your key in chrome.storage — your browser's own secure storage system. The key is never sent to SnapFill's servers (we have none). It only leaves your browser when you trigger an AI action, going directly to Google's API. See our Privacy Policy for full details.
API keys can occasionally be rotated or revoked. If your key stops working, go back to aistudio.google.com/app/apikey, generate a new key, and update it in SnapFill Pro's AI Brain Settings.
Yes. SnapFill Pro supports any OpenAI-compatible endpoint. Popular free alternatives include Groq (fast inference, free tier) and Ollama (fully local, 100% free). Configure the endpoint URL and key in AI Brain Settings.
SnapFill Pro is configured to use Gemini 1.5 Flash by default — Google's fastest and most cost-efficient model, perfect for real-time application drafting.
