Yes. Every tool you see today is free with no signup, no email, and no credit card.
The tools themselves don't send your input anywhere — anything you type, paste, or generate inside a tool stays in your browser. Like most websites, the page itself loads through a hosting provider (Cloudflare) and we use standard web analytics on visits. See the Privacy page for details.
No accounts, no logins, no email capture. Open any tool and use it.
The tools produce plain text files (robots.txt, sitemap.xml, llms.txt, etc.) and standards-compliant markup snippets — none of which can execute code or compromise a site. The real risk is overwriting an existing file that had custom rules you forgot about. That's why we recommend keeping a copy of your current file before replacing it, and testing on a staging environment if you have one.
The SEO tools generate site-level files (sitemap.xml, robots.txt, meta tags, schema markup, etc.) for website owners and developers. The seller tools generate listing copy (descriptions, titles, tags) for Etsy, Shopify, and eBay shop owners. Same browser-only privacy, different audience.
