What is the AI Caption Generator?

The AI Caption Generator analyzes your images using advanced AI vision and creates engaging captions, hashtags, and social media posts optimized for different platforms like Instagram, Twitter, LinkedIn, and more.

What image formats are supported?

We support JPG, JPEG, PNG, and WebP formats. You can either upload a file (max 10MB) or provide an image URL.

How many caption variations can I generate?

You can generate 1-5 caption variations per request. Each variation offers a unique perspective or angle on your image.

What is NSFW filtering?

NSFW (Not Safe For Work) filtering automatically detects inappropriate content in images. If detected, caption generation will be blocked, but credits are still charged as a penalty. Keep this filter enabled for safety.

Can I customize the captions?

Yes! You can customize tone (funny, professional, trendy, etc.), platform (Instagram, LinkedIn, etc.), caption length, include/exclude emojis and hashtags, add custom keywords, choose language, and even add custom instructions.

How much does it cost?

It costs $0.02 per request (flat rate), regardless of the number of variations (1-5) you generate.

What languages are supported?

We support English, Spanish, French, Hindi, German, Italian, and Japanese.

How long does it take?

Caption generation typically takes 3-5 seconds using AADDYY's AI.
