Upload your photo

Expect: Simple photos: 15-20 seconds. Complex scenes with multiple subjects: 25-30 seconds.
Request caption generation

Type 'generate a descriptive caption for this photo' or 'create accessibility description for this image.' The AI analyzes visual elements, people, objects, setting, and mood to create comprehensive captions.

Tip: Specify the caption purpose: 'for social media,' 'for accessibility,' or 'for SEO' to get optimized results.

Try This →

Try This →
Review the generated caption

Check that the AI captured key visual elements accurately. The caption should describe who or what is in the photo, the setting, colors, emotions, and important details.
Refine if needed

If you need specific details emphasized or different tone, request adjustments: 'make it more professional' or 'focus on the clothing details.' Most captions work perfectly on the first try.

Tip: The AI understands context—specify if captions are for visually impaired users, social media, or technical documentation.

If something looks off

AI caption is too generic or misses important details

Why: The AI needs more specific guidance about what aspects of the photo to emphasize or the intended use case.

Try:

generate a caption for this photo focusing on [specific elements like clothing, expressions, background] for [accessibility/social media/SEO] use

Try This →

Tip: Be specific about the caption purpose and which visual elements matter most for your use case.

Caption is too long or too short for my needs

Why: Different platforms and use cases have different optimal caption lengths. The AI can adjust based on your requirements.

Try: create a [brief/detailed] caption for this photo, approximately [X] words for [platform/purpose]

Try This →

Tip: Specify length requirements upfront: 'brief for alt text' or 'detailed for accessibility' gives better results.

AI describes the wrong focus or main subject

Why: Complex photos with multiple elements may confuse the AI about what's most important to describe first.

Try:

generate a caption for this photo focusing primarily on [the person/the object/the background/the activity] as the main subject

Try This →

Tip: Guide the AI's attention by specifying the primary subject when the photo has multiple focal points.

Caption tone doesn't match my needs

Why: The AI defaults to neutral, factual descriptions but can adjust tone based on your specific requirements and audience.

Try: write a [professional/casual/engaging/formal] caption for this photo suitable for [audience/platform]

Try This →

Tip: Tone keywords like 'professional,' 'friendly,' or 'technical' help the AI match your communication style.
