AI tool registry
2,932 AI tools. One question each: what does Article 50 want from you?
This is the live detection registry behind the Klarvo WordPress plugin — grown weekly by an automated sweep of the plugin directory, classified by KlarvoEngine, human-reviewed where uncertain. Find your tool, get the plain-English duty, copy the disclosure.
Chatbots & assistants
932 tools
Tools that talk to your visitors — chat widgets, AI assistants, support bots. These are the clearest Article 50 case: a person is interacting with an AI, so they must be told.
Content generation
681 tools
Writing assistants, blog generators, product-description tools. The output is synthetic text, and the duty follows the content: providers must mark it, and publishers of public-interest text without human editorial review must say it's AI-generated.
SEO & optimisation
262 tools
AI tools that write meta descriptions, generate schema, optimise content for search. Mostly synthetic-content generators in disguise — the text they produce carries the same marking expectations.
Image, audio & video generation
252 tools
Generators and editors for images, audio and video. Synthetic media is where the Act is most explicit: machine-readable marking for providers, and a visible label when the result is a deepfake of real people, places or events.
E-commerce AI
228 tools
Product-description writers, AI merchandising, review summarisers for shops. Usually a content-generation duty; an embedded shopping assistant adds the interaction disclosure on top.
Translation
90 tools
Machine-translation plugins and services. Translated text is AI-generated text; the practical duty is honesty about machine translation where readers would otherwise assume a human translator.
Voice & speech
84 tools
Text-to-speech, voice cloning, speech recognition. Synthetic audio carries the marking duty, and cloned voices of real people are deepfakes with an explicit disclosure obligation.
AI analytics
81 tools
Behaviour analysis, predictive analytics, AI-scored insights about visitors. Often minimal transparency risk — the AI watches rather than talks — but profiling-adjacent uses deserve a scope check.
AI search
77 tools
Semantic site search, AI-powered product finders, answer engines. Where results read as generated answers rather than ranked links, the interaction disclosure starts to apply.
Security & anti-spam
58 tools
AI spam filters, threat detection, bot screening. These protect rather than persuade — typically no transparency duty toward visitors.
Personalisation
47 tools
Recommendation engines, dynamic content, AI-picked layouts. Recommending is not conversing — Article 50 rarely bites — but the line moves if the personalisation talks to the visitor.
Accessibility AI
33 tools
Overlay widgets, AI alt-text, reading assistants. Many inject visible AI-driven interfaces for users who rely on them — transparency matters more here, not less.
Email & messaging AI
30 tools
AI email writers, smart replies, campaign generators. Outbound synthetic text — the marking expectations follow the message.
Fraud detection
25 tools
Payment screening, fake-account detection, risk scoring of transactions. Financial fraud detection is explicitly outside the Act's high-risk credit rules, and there's no Article 50 duty in watching for abuse.
Identity & verification
17 tools
Document checks, liveness detection, identity matching. One-to-one verification — matching a person against their own claimed identity — sits outside the Act's remote biometric identification rules, but the area rewards a careful scope check.
Advertising AI
15 tools
Ad copy generators, AI targeting, creative optimisation. Generated creatives carry content duties; targeting of job ads specifically crosses into the Act's employment high-risk territory.
Forms & data capture AI
6 tools
AI form builders, smart field validation, conversational forms. The conversational variants are interactions; static smart forms typically are not.
Social media AI
6 tools
Auto-posting, AI social content, engagement tools. Synthetic posts at scale — content duties apply, and undisclosed automated personas raise exactly the concerns the Act codifies.
Scheduling & booking AI
5 tools
AI booking assistants and smart schedulers. Where the booking flow is conversational, the interaction disclosure applies; pure calendar optimisation carries no duty.
Video AI
3 tools
AI video generation and avatar presenters. Synthetic video — and avatar doubles of real people are deepfakes with an explicit visible-disclosure duty.
How entries earn their page
1,474 tools are catalogued with vendor or behavioural detail; the rest are currently detected by install signature only and their pages say so honestly. Verdicts cite the clause that drives them — Article 50(1) for tools that talk to your visitors, 50(2) for synthetic-content generators, 50(4) for deepfake and public-text labelling, or no duty where none applies.
Questions site owners actually ask
What is this registry?
The live catalogue of 2,932 AI tools Klarvo can detect on websites — the same detection set the free WordPress plugin uses. For each tool it answers one question in plain English: does it trigger an EU AI Act Article 50 transparency duty, and if so, what do you have to show?
Does a tool appearing here mean using it breaks the rules?
No. Most entries carry a perfectly manageable duty — usually a one-line disclosure — and many carry none at all. The registry tells you which is which, per tool.
My AI tool isn't listed — what does that mean?
The registry grows weekly: an automated sweep of the WordPress.org directory finds new AI tools, KlarvoEngine classifies them, and a human reviews the uncertain ones before they're published. A missing tool simply hasn't been catalogued yet — the scope check below gives you a verdict for any tool today.
How accurate are the verdicts?
Each entry reflects the tool's typical deployment, classified against the Act's text and reviewed under the registry's confidence rules — pages for tools detected only by an install signature are marked accordingly. Your specific configuration can change the answer, which is what the free scope check is for.
