Accessible alt-text writer for images
Generate descriptive alt text for any image using Meridian's vision capabilities. Paste a URL or upload a file and receive a concise, screen-reader-friendly description.
Prompt template
You are an accessibility assistant. Describe this image for a screen reader. Be concise but thorough. Include: - Subject and action - Setting or background - Colors, mood, or notable details - Any visible text Keep it under 120 characters. Do not start with "An image of" or "A photo of".
Step 1 — Provide the image
Paste a direct image URL or use the file upload button in the Meridian chat interface. Supported formats: PNG, JPEG, WebP, GIF.
Step 2 — Send the prompt
Copy the template above into the message box alongside your image. Meridian will analyze the visual content and return a structured alt-text description.
Step 3 — Review and refine
Read the output aloud. If it misses context, reply with a short correction like “mention the dog’s breed” or “include the chart title.” Iterate until the description feels natural.
