Hit Go & Review
We process everything, you review what we came up with, approve the good stuff. Takes way less time than writing from scratch.
Developer Integration

Alt Text Tool Features for Real-World Workflows
Advanced alt text tool features we built because we needed them ourselves when processing thousands of images.
Protects Existing Alt Text
Already have great alt text? We'll skip it. You review everything before it goes live. No surprises, no accidents.
Context-Aware Processing
Note that we use e-commerce data. We're not really always doing context stuff, but we are using SEO keywords if they are available, and we use AI to generate SEO keywords if none are provided. If we have product descriptions.
Background Processing
Large jobs process in the background while you do other things. We'll email you when it's done.

Customize Your Alt Text Tool Experience
Every brand has a voice. Ours is pretty casual (obviously). Yours might be different. Here's how to customize our alt text tool for your specific needs.
130+ Languages
French website? Japanese product catalog? We got you. Set your language once or mix them per collection. Global optimization guide →
Tone & Style
Corporate speak? Casual? Technical? You tell us how your brand talks, we'll match it.
Length Control
Short and sweet? Long and detailed? Set max characters and we'll stick to it. 125 characters works great for most sites.
White Label
Agency? Remove our branding completely. Your clients never need to know we exist. We're cool with that.
ChatGPT Prompts
After we generate the initial alt text, have ChatGPT modify it with your custom prompt for advanced control.
Post-Processing Enhancement
Our AI generates the initial alt text, then ChatGPT refines it according to your specific prompt and requirements.
Global or Per-Image
Apply your prompt globally for consistency or per image for maximum control over each final description.
Free For Everyone
Our ChatGPT feature comes with every account at no extra cost! Perfect for brand-specific tone and style.
Example Custom Prompt
Use the custom prompt field to get descriptions that match your brand voice and industry requirements.
Privacy & Security
We don't store your images. Clear data handling policies.
Privacy-First Processing
We do not permanently store your images. For processing, images may be temporarily cached (≈40s) or retrieved by URL; we retain only the image URL, generated alt text, and metadata. Server-side API usage only; rate limiting and access controls in place.
Secure Processing
All API requests use HTTPS encryption. Images processed server-side with enterprise security standards.
Temporary Cache Only
Images cached briefly for processing efficiency, then automatically purged. No permanent image storage.
