Limits and what to check
It runs entirely in your browser and nothing is uploaded. Each sitemap is limited to 2 MB and 50,000 entries, and larger input is refused rather than cut short. The child sitemaps are not fetched or checked. Make sure each address is public and on the same site as the index file.
This tool runs in your browser and does not use an AI model.
Frequently asked questions
Using the tool
Q1Do you check the child sitemaps?
No. The index is built from the addresses you paste and those files are not fetched. Check each one with the sitemap checker or validator.
Q2Is the sitemap index built on my device?
Yes. It is created in your browser and nothing is sent to AI Smarty. Inputs are limited to 2 MB.
Q3When do I need a sitemap index?
When your URLs are split across several sitemap files, for example by section or because one file would be too large. The index lists them all.
Q4Can child sitemaps be on another domain?
Keep child sitemaps on the same site as the index unless you have verified both sites in Search Console. Check each child address before you publish the index.
