Step-by-Step Walkthrough

Step 1: Access Google AI Studio

Go to Google AI Studio and sign in with a standard Google account. No credit card or payment method is required to access the free tier.

Step 2: Upload Your Image

Start a new chat and upload your target image using the attachment (paperclip) icon at the bottom of the chat interface.

Step 3: Apply the Prompt Template

Paste the following prompt into the chat box and send it alongside your image.

Act as an accessibility specialist. Write a detailed, screen-reader-friendly alt-text description for this image. Focus on: 1. The main subject and action. 2. Relevant text visible in the image. 3. The setting, lighting, and mood. 4. Any critical details a visually impaired person would need to understand the context. Keep the description under 150 words. Do not start with "This image shows".

Step 4: Review and Deploy

Review the generated description. Make any minor manual adjustments for hyper-specific context, then copy it directly to your website, social media post, or document.

⚠️ What Breaks (Limitations)

Highly abstract art or heavily text-dense infographics may require a follow-up prompt to extract specific data points accurately.
The free tier enforces a strict rate limit of 15 requests per minute and 1,500 requests per day. If you hit this, you must wait for the rolling 24-hour window to reset.
Google AI Studio requires a Google account; it is not an anonymous or fully private workflow.

Three Things to Remember

1. No credit card is required

Google AI Studio's free tier is genuinely free and does not ask for payment details to access the 1,500 daily requests.

2. Quotas reset on a rolling 24-hour basis

If you hit the 1,500 request limit, you do not have to wait until midnight. The limit resets exactly 24 hours after each individual request was made.

3. Specific prompts yield better results

Generic commands like "describe this" produce vague outputs. The provided template forces the model to focus on screen-reader priorities like text, mood, and critical context.
