Alt Text Accessibility Helper
Write alt text fast, correctly, and consistently
Generates accurate alt text for images and carousels across any platform that supports it (Instagram, X, LinkedIn, Pinterest, Facebook). Improves accessibility, boosts search discoverability, and reduces creator friction with a reusable style guide.
PROMPT
Create a skill called "Alt Text Accessibility Helper". Ask me to describe each image (or slide) in plain language, and which platform(s) I'm posting to. Then generate custom alt text: - concise (1–2 sentences) - factual and descriptive - includes relevant on-image text if present Also provide: - a short style guide so future alt text stays consistent - platform-specific notes (where to add alt text, character limits if any)
How It Works
You describe the image(s) as if you're explaining to someone who can't see them. The skill returns
concise alt text drafts and a consistency guide for your account.
Inputs
- Platform(s)
- Image description(s) you provide (1–10 images)
- Tone preference (neutral, slightly warm)
- Any important details (brand/product, location, step-by-step)
Outputs
- Alt text per image (concise, factual)
- "What to include" checklist (people, objects, text in image, context)
- Reusable style guide for future alt text
- Platform-specific notes (character limits, where to add alt text)
Examples
- Input: "Carousel: 5 slides about pricing tiers, posted on Instagram + LinkedIn."
Output: "Alt text for each slide + platform-specific placement notes."
- Input: "Photo: me holding a skincare product in a bathroom."
Output: "Single-sentence factual alt text draft."
