We are happy to introduce our new project — sitetest.ai, a free AI Visibility Checker that tells you how well your site is seen by generative search engines: ChatGPT, Perplexity, Google AI Overviews, Gemini and Bing Copilot.
What it does
One tool, three layers of insight:
- 168 checks across 10 categories — technical, on-page, content, performance, schema, security, accessibility, images, GEO and frontend. Every check is documented with business impact and a copy-paste fix.
- Per-engine scoring — sitetest.ai probes GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, Google-Extended and bingbot independently. You see exactly which AI surface you're invisible to, not just an aggregate index.
- Brand mention scanner — separately queries ChatGPT, Perplexity and Gemini for your brand name, founder name and product terms. Re-run monthly to track real authority growth in AI answers.
- Developer brief — an exportable report with ready-to-ship code fixes (HTML, JSON-LD, robots.txt) you can hand directly to engineering.
How it works
Paste a URL — get an A–F grade in 60–90 seconds. No signup, no card, no email gate. The free tier covers the full audit. Paid tiers ($4.99 / $14.99 / $24.99 one-time, no subscription) add the detailed developer brief, re-audits and pro extensions.
Stack
Built on Nuxt 3.21 with SSR and seven locales (en/uk/de/es/uz/kk/ru). The blog ships seven cornerstone articles on AI Search Engine Optimization, GEO and llms.txt, each translated into all seven languages. Backend: PostgreSQL + Redis + BullMQ for the audit queue, DeepSeek as the primary AI model with GPT-4.1-mini fallback.
