Sightline will not tell you your store is compliant. No app can honestly promise that. What it does: scan every product image, list the ones with no alt text, and let you fix them in bulk after you review each suggested description. Nothing is written to your catalog without your approval. A contrast checker grades the colors you use against readable-text guidelines. Every scan and fix is saved with its date, so you have a record of exactly what was found and what you did about it.
