EU AI Act Article 50: does your chatbot say it is an AI, and is your output marked?

Article 50 of the EU AI Act, on telling people they are dealing with an AI and on marking what AI generates, applies from 2 August 2026: “It shall apply from 2 August 2026.” (AI Act, Art. 113, second paragraph, Regulation (EU) 2024/1689). Generative systems already on the market before then have until 2 December 2026 to mark their output. This page and the free checker show what your site and your files carry, against the law's own words.

Does the chat widget or assistant tell people it is an AI, before or at the first exchange? Reads the page as served: text, aria labels, the inline settings of the chat vendors it can name.

Is a generated image, audio, video or text file marked in a machine-readable way? C2PA Content Credentials, IPTC and XMP AI fields, a declared watermark, California's latent-disclosure fields.

One request per URL you give it; files are read on your machine and never uploaded. No account, no LLM calls. It reports what it finds against what the law says, never a verdict. Also as a GitHub Action that checks a URL on a schedule: agentwares/agent-disclosure.
