Quick comparison
| Tool | What it does | Open |
|---|---|---|
| AI Text Detector & Humanizer | This free AI Text Detector & Humanizer estimates how AI-generated a piece of text reads — based on sentence uniformity, buzzword density, generic transitions, and personal voice — and rewrites it to sound more natural. The score is an estimate, not a guarantee: no detector can prove who or what wrote a text. | Open → |
| Prompt Optimizer | A prompt optimizer scores your prompt against prompt-engineering best practices (role, context, constraints, output format) and rewrites it into a clearer, model-specific version. This free tool supports ChatGPT, Claude, Gemini and Perplexity and runs in your browser. | Open → |
| AI Citation Checker | An AI citation checker analyzes a web page for the signals AI search engines reward — clear structure, structured data, concise answer blocks, FAQs and E-E-A-T — and estimates how likely it is to be cited by ChatGPT, Gemini, Perplexity and Google AI Overviews. Results are an estimate, not a guarantee of citation. | Open → |
| Schema Generator | A schema generator creates JSON-LD structured data — the markup search engines and AI use to understand a page. This free tool generates valid FAQ, Article, Product, Organization, Breadcrumb, SoftwareApplication and LocalBusiness schema you can paste straight into your HTML. | Open → |
| Internal Link Generator | An internal link generator scans an article against a list of your site's URLs and recommends relevant internal links — the target page, suggested anchor text, and where to place the link. This free tool runs in your browser and helps distribute link equity and improve crawlability. | Open → |
| Regex Explainer | A regex explainer deconstructs a regular expression pattern into its individual components and explains each one in plain English — showing what the pattern matches, what it rejects, and why. | Open → |
| SQL Query Generator | SQL generators translate natural-language descriptions into valid SQL queries — including SELECT, JOIN, GROUP BY, and subqueries — so you can query your database without memorising SQL syntax. | Open → |
| Docker Compose Generator | A Docker Compose generator creates a valid docker-compose.yml from a description of your services (e.g. 'Next.js app + PostgreSQL + Redis') including health checks, volumes, networking, and restart policies. | Open → |
