Frequently Asked Questions
What exactly is Altxt AI and what does it do?
Altxt AI is an image description generator that automatically writes accurate, SEO-friendly alt text. You upload images and get ready-to-use results in seconds. It uses vision models to identify objects, scenes, and context, then outputs clean descriptions optimized for both search engines and accessibility.
Why do missing image descriptions hurt my website?
Without alt text, search engines can't understand your images. Google Images drives significant traffic, and missing descriptions make your pictures invisible there. Screen readers also depend on alt text to help visually impaired visitors navigate your site. Altxt AI solves both problems at once.
How do I get started?
It takes seconds. Open Altxt AI in your browser, upload an image or paste its URL, and you'll get a description instantly. No account needed, no email required, no credit card. Just upload, copy the generated alt text, and paste it into your image's alt attribute.
What types of images does it handle best?
Altxt AI works with virtually any image type: e-commerce product photos, blog featured images, infographics, screenshots, team headshots, social media graphics, real estate listing photos, and portfolio images. The output adapts to match the content of each image automatically.
How accurate are the generated descriptions?
Highly accurate. The AI analyzes multiple visual elements—objects, colors, text, spatial relationships, and scene context. It doesn't guess or hallucinate details. It also avoids starting with 'image of' or 'picture of,' following accessibility best practices.
Does it help with accessibility compliance?
Absolutely. WCAG 2.1 requires meaningful alt text for all informational images. Altxt AI generates descriptions that meet these guidelines out of the box—concise, descriptive, and free of redundant phrases.
Is it free to use?
Yes. Altxt AI offers free access with no registration required. Upload images and get results immediately—no account, no credit card. For power users who need high-volume batch processing, premium plans are available.
