Most "free" SEO tools hide their best features behind a signup wall or hand you rough estimates. Tech Vault AI takes the opposite approach: every tool here is genuinely free, needs no account, and works from the real HTML of your live pages. Whether you are a blogger, a local business owner, a freelancer, or an agency, you get honest numbers you can act on — not a sales funnel.
Start broad with the Website Audit, which runs 40+ checks across technical health, on-page SEO, content, and structured data, then hands you a prioritized fix-this-week plan. When your traffic depends on a physical location, the Local SEO Checker audits NAP consistency, LocalBusiness schema, and Google Business signals, with click-to-fix guidance on every issue it finds.
Search is changing fast. AI answer engines like ChatGPT, Google AI Overviews, and Perplexity now answer questions directly, so being cited matters as much as ranking. The AI Answer-Readiness Score measures how well your content is set up to be quoted by these engines and gives you a concrete checklist. Before you hit publish, the SERP Snippet Preview shows a pixel-accurate view of your title and meta description on desktop and mobile, so nothing important gets cut off.
Clean structured data helps both search engines and AI engines understand your pages. The Schema Markup Generator produces valid JSON-LD for articles, products, local business, FAQs, breadcrumbs, and reviews in a couple of clicks. To make sure crawlers can actually reach your content, the Robots.txt & Sitemap Validator flags blocking rules and sitemap problems, while the Tech Stack Detector reveals the frameworks, CMS, analytics, and hosting behind any site. And when it is time to get paid, the Invoice Generator creates clean, professional PDF invoices right in your browser. Together, these 8 free tools cover the full loop — audit, fix, publish, and bill.
