Lucenta

Lucenta brings three tools together in one free web app.

Website Analyzer: enter any URL and Lucenta audits it for performance, SEO, accessibility, security, best practices, mobile readiness and content quality. It gives an overall score and grade, an AI-written review, a prioritised list of fixes ranked by impact and effort, missing security headers, and a detected tech stack. Reports are saved, can be re-scanned, and can be handed to a developer through the built-in "Hire a developer" directory.

AI Text Detector: paste text and get an AI probability with sentence-by-sentence highlighting, confidence, and a plain-English explanation of why (burstiness, sentence length, lexical diversity and common AI phrases). A responsible-use note reminds users that a score is an estimate, not proof.

Rewriter: a Suggestions mode points out robotic, unclear, wordy or passive sentences and explains how to fix them without rewriting the text, so the writing stays the user's own. Rewrite mode (for non-students) polishes the tone while keeping the meaning, with a similarity check and a note about disclosing AI use.

The app includes Supabase authentication with onboarding (age 16+, occupation and referral source), fair daily free limits, device and IP abuse protection, scan and text history, profile and settings pages, a dark/light X-inspired theme, legal pages (Terms, Privacy, Responsible use), and an hourly keep-alive job.
