AI writing assistants and Article 50
AI writing assistants — draft generators, rewriters, and grammar and tone helpers — sit inside word processors, inboxes, and content platforms. The EU AI Act paragraph most often raised for generated text is Article 50(2), the provider-side marking of synthetic text. But that paragraph also carries carve-outs that matter especially to editing-style tools. This guide explains the text and the carve-outs from the regulation. It is informational only, not legal advice, and does not name any tool category as in or out of scope.
Marking synthetic text — Article 50(2)
Article 50(2) asks providers of AI systems generating synthetic audio, image, video or text to ensure the outputs are marked in a machine-readable format and detectable as artificially generated or manipulated, with solutions effective, interoperable, robust and reliable as far as technically feasible. As written, this marking duty sits on the provider of the writing system — not on every author who accepts a suggestion. Whether a given writing assistant produces 'synthetic ... text content' within the meaning of 50(2) is a fact-specific question, and text has its own detectability limitations the paragraph acknowledges.
The assistive-editing and no-substantial-alteration carve-outs
The same paragraph adds that the obligation does not apply to the extent the AI systems perform an assistive function for standard editing or do not substantially alter the input data provided by the deployer or the semantics thereof. That language is directly relevant to writing assistants that correct grammar, adjust tone, or lightly rephrase existing text a user supplied. Whether a particular feature 'performs an assistive function for standard editing', or 'does not substantially alter the input data or the semantics thereof', is fact-specific — a full draft generated from a short prompt sits differently from a spelling fix. If you intend to rely on a carve-out, document the reasoning for counsel.
Common questions
Does an AI grammar or rewriting tool need to mark its output?
Article 50(2) carries a carve-out to the extent a system performs an assistive function for standard editing or does not substantially alter the input data or its semantics. Whether that fits a grammar or rewrite feature — and whether the marking duty otherwise applies to the provider — is fact-specific. Verify with qualified counsel.
