Lightweight limit and Central bridge

Good product alt text names what is visible and useful: product type, color, view, packaging, variant, and relevant context. It should not add unverified performance claims, certifications, or invisible specs.

what it can do

Use the free tool for one focused product task.

  • Alt text: Concise image description.
  • Shorter alt: Short alternative for strict CMS fields.
  • Decorative guidance: If decorative, suggest empty alt handling.
  • Claim warnings: Flag invisible or unsupported claims.
where Central adds proof

Connect the task to verified product records.

The tool can describe visible image details and use facts the user provides. It cannot verify invisible product claims from an image alone.

Inside Central, image metadata can be tied to verified product facts, source trails, confidence, and review states. Fact-based image and richer asset workflows should be marked Coming Soon until shipped.

FAQ

Questions before you start.

Can alt text include product specs?

Yes where implementation supports reading the URL. If the image cannot be read, show a calm error with an upload fallback.

Does the tool verify claims from the image?

+

No. It can warn about unsupported claims. Central handles product-record verification.

Can Central handle image metadata in bulk?

+

Yes where implemented. Mark richer asset intelligence or generation workflows Coming Soon until shipped.
