AI Alt Text Generator
The Product
ImageAltAI is an AI Image SEO Tool built keeping SEO pros and beginners both in mind; who don’t want 42 clicks to write one alt tag.
It creates SEO-friendly Alt text, Captions, and File names for images. You can upload one image (like most alternative Image Alt Tools let). Or, up to 15 in bulk (only a couple tools let do). We go a step further and let just paste a live URL - fetch its images - and suggest image metadata, unlike any other (as of Dec '25). We call it Page Scan feature.
Perfect for blogs, SaaS, eCommerce, agencies, and anyone who wants search engines, answer engines, and LLMs to understand their images. Plus, in line with W3C (and plausibly your local government's) Web Accessibility Initiative.
And... it’s Free! No signup. No daily limits.
Reason to Build
Why?
Because most images online are basically whispering “figure me out” to Google and ChatGPT. Manual metadata writing is the kind of task only free-loading SEO interns enjoy.
We saw creators, marketers, and businesses skip alt text not because they don’t care — but because the process is unnecessarily painful.
So we built a tool that does the heavy lifting in seconds, stays accurate, and accessible even if you’ve never heard of Neil Patel.
Methodology to Build
How?
Our AI analyzes each image, understands what’s happening in it, and generates metadata based on real-world SEO best practices.
The backend uses OpenAI’s latest models, prompt-engineered for higher accuracy, keyword sensitivity, and context awareness — whether it’s a single hero image or a full gallery.
The result? Consistent, clean, SEO-ready metadata with a UI simple enough for beginners and fast enough for power users.

FAQs on ImageAltAI, possibly the best Image SEO Tool
What is the need for another AI alt text generator tool?
Fair question. There are many alt text generators — but most feel like they were built in a rush during a hackathon and then forgotten.
We built the ImageAltAI because creators needed alt text + caption + file name, not just a line of text.
Plus, none offered the Bulk Upload, or Page Scan features
So yes — the world didn’t need another tool… it needed a better one.
What are the various features of this tool that make it unique?
Three features whose simplicity and practicality make it unique:
1. Single Image → Get all image metadata (alt text + caption + file name) instantly.
2. Bulk Upload → A rare, user-friendly batch (up to 15) image meta generator.
3. Page Scan → Paste a URL and optimize up to 10 images without downloading anything. An original idea.
It’s free, fast, and doesn’t make you sign up to always be wary of another promotional email. Also, no daily limit.
Does ImageAltAI support languages other than English?
Not yet. But that's the next high-priority feature we plan to work on. So, keep an eye out!
Is ImageAltAI.com really free? Will it stay free in the future?
Yes — it’s free, and there’s no hidden catch.
Long term, we might explore optional paid upgrades, but the basic AI Alt Text Generator tool will remain free.
Will you increase the limits — like more than 15 images in bulk or more images in Page Scan?
Not immediately. But yes, bigger batch limits are on the roadmap. If you want this accelerated, feel free to reach out via email or LinkedIn.
Do you offer an API or plan to offer API access?
Right now, no. Sorry. But API access is definitely in the future. If your team needs it sooner, drop a message — we’re flexible.
Can businesses or agencies integrate this tool into their workflow or CMS?
Not natively yet. But CMS integrations may happen later, once usage grows. So, do share it with your SEO peers.
How safe is my data? Do you store the images or URLs I upload?
Totally safe. We don’t store your images or URLs. Processing is temporary and happens securely through our backend. Once the generation is done, we don’t keep anything.
Can I request a new feature or customization for my team or workflow?
Absolutely. We’re small, hungry, and always listening.
