EU AI Act · Article 50 · Regulation (EU) 2024/1689
The marking grace period ends December 2, 2026
Article 50's transparency duties have applied since August 2, 2026. AI systems that were already on the market before that date get until December 2, 2026 to meet the machine-readable marking duty for their output. After that date there is no grace left — and breaches of Article 50 carry fines of up to €15 million or 3% of worldwide annual turnover, whichever is higher.
This free tool marks one piece of AI-generated text: it embeds machine-readable marking and writes the human-visible disclosure for you, then records the event in an exportable marking log. Everything runs in your browser — your text never leaves your machine.
This tool produces unsigned machine-readable metadata marking. It does not produce cryptographically signed Content Credentials, and it is not legal advice, not a certification, and not a guarantee of compliance.

Your marking log (the evidence layer)
Every marking event is recorded here — content hash, timestamp, level — and stays in your browser. Export it and keep it with your records.
3 · Stay marked: monitoring, $29/mo
Marking one file is a task. Marking everything you publish, every week, and proving it later is a system. The monitoring tier:
Batch marking — multi-file runs through the same marking pipeline.
Disclosure widget pack — an embeddable disclosure widget plus caption and text templates for your own pages and posts.
A kept marking log — every marking event logged (file hash, timestamp, marking level) and exportable: your evidence file if an authority or a platform asks.
Rule-watch alerts — when the Article 50 rule pack changes (dates, guidance, marking standards), you hear about it with what changed and what it means for your content.
$29/mo · or $290/yr annual prepay. No lifetime deal during the test phase.
