What can run in your conversation
- Shopify product CSV checks and transaction CSV comparisons.
- OpenAPI 3.0 contract comparisons and sitemap/robots checks.

- Catalogue search that identifies in-chat support and links to every website utility.
What opens on the website
Image, PDF, audio and video utilities use browser features and stay on their existing pages. Password and secret-related tools also stay in the browser. Finding a tool through the plugin does not mean it can process files in the conversation.
Your inputs and the limits
Data passed to a computation tool is sent to UtilZilla’s Vercel backend for transient processing. The tools do not store inputs in a database. Hosting providers may retain operational metadata. Avoid submitting secrets or payment card data. Each tool validates its input limits; these are bounded checks and estimates, with no external account changes, website crawling or calendar invitations.
Try: “Find a tool to merge PDFs,” “Compare these two JSON documents,” or “Convert this CSV into a Markdown table.”
