AI Explainer

Description

AI Explainer analyses your published WordPress content with a multi-method detection engine, displays transparency badges to readers, and gives you a dashboard to keep track of AI-related content on your site.

The detection engine combines five complementary local heuristic methods (statistical, linguistic, structural, vocabulary, repetition) to estimate the probability that a piece of text was generated by AI.

Features

  • Five-method local detection engine — no external service required
  • Authenticity badges (human / AI / mixed) on posts
  • Public /authenticity page — standalone “Verified Human Content” page on your domain, plus an embeddable trust badge other sites can drop in
  • AI scraper defense — blocks 22 known AI training crawlers (GPTBot, ClaudeBot, CCBot, PerplexityBot, Bytespider…) via robots.txt
  • 4-step Get Started onboarding wizard with live progress tracking
  • Manual content declaration meta box (author can declare “human”, “AI” or “auto-detect”)
  • Admin detector page — paste any text and analyse it
  • Dashboard with content inventory and scan history
  • EU AI Act transparency dashboard (informational checklist + downloadable HTML report)
  • Multilingual detection dictionaries (English, French, Spanish, German, Italian, Portuguese)
  • REST API under the ai-explainer-pro/v1 namespace
  • WordPress dashboard widget with content overview

Detection methods

  1. Statistical — sentence-length variance (burstiness), entropy, average length
  2. Linguistic — transition words, formal vocabulary, hedging phrases, personal pronouns
  3. Structural — paragraph uniformity, list/heading patterns, topic-sentence formulas
  4. Vocabulary — Guiraud index, hapax-legomena ratio, word-length distribution
  5. Repetition — repeated bigrams and sentence-opening patterns

Each method produces a 0-1 score. Scores are combined into a weighted ensemble.

REST API

Endpoints under ai-explainer-pro/v1 (all require manage_options):

  • POST /detect — analyse arbitrary text
  • POST /scan-post — scan a specific post by ID
  • POST /bulk-scan — batch scan with offset/limit
  • GET /stats — overall detection statistics
  • GET /compliance — EU AI Act transparency data
  • GET /post-status/{id} — detection status for a post

Important disclaimer

Local heuristic detection produces directional indicators. It works well for clearly AI-generated or clearly human text, but edge cases exist. Results vary depending on content type, length and language. The EU AI Act transparency dashboard is informational only and does not constitute legal advice — consult a qualified legal professional for any compliance question.

Paid add-on (sold separately, hosted off-site)

A separate paid version is available at https://aiexplainerpro.noveralis.com. It is sold and downloaded from the developer’s own website and is not bundled with this plugin. Every feature listed above works in this plugin without the paid add-on.

External services

This free plugin (the version hosted on WordPress.org) does not call any external service. All detection is performed locally on your server.

The optional paid add-on is sold and hosted off-site at https://aiexplainerpro.noveralis.com. It is a separate plugin and its external service calls are documented on the developer’s website. Nothing the paid add-on does affects the free plugin’s behaviour.

Privacy

Stored locally:

  • Detection scores (post meta)
  • Scan history (custom database table)
  • Plugin settings (WordPress options)

Not collected:

  • No visitor tracking, no cookies, no analytics

External calls: none, in the version distributed on WordPress.org. See the “External services” section for the optional paid add-on.

Uninstall: removing the plugin clears all options, post meta, custom tables and transients.

FAQ

How does detection work?

Five complementary local heuristic methods (statistical, linguistic, structural, vocabulary, repetition) each produce a 0-1 score. Scores are combined into a weighted ensemble.

How accurate is the detection?

Accuracy depends on content length, type and language. Longer texts (200+ words) produce more reliable results. We do not advertise a specific accuracy figure because it would vary too much across content types.

Does this slow down my website?

No. Detection runs only during admin-initiated scans. Badge display reads cached post meta — that is instant.

What data is sent externally?

Nothing, by default. All analysis runs locally on your server. The optional paid add-on can be configured by the user to call OpenAI; that is documented in the “External services” section above.

Is this GDPR friendly?

The plugin does not set cookies, does not track visitors, and stores all data in your own WordPress database.

Can I customize the badges?

Yes — choose between three templates (modern, pill, minimal), set the position (top, bottom, both), and toggle which badge types appear.

Which languages are supported?

Detection dictionaries cover English, French, Spanish, German, Italian and Portuguese. Developers can extend them via filters (ai_explainer_pro_transition_words, ai_explainer_pro_formal_words, ai_explainer_pro_hedging_phrases).

Is there a REST API?

Yes. Six endpoints under the ai-explainer-pro/v1 namespace. All require manage_options. See the Description tab for the list.

What about the EU AI Act?

The EU AI Act (Regulation 2024/1689) introduces transparency obligations for AI-generated content. The plugin’s transparency dashboard offers an informational checklist and a downloadable HTML report to support your own compliance review. It is not legal advice.
