This one needs two separate duties untangled, because the honest answer differs between them, and one part is genuinely unclear rather than a confident yes or no.
For the published AI-text duty (Article 50(4)): internal documents and private correspondence are explicitly not "published" for this purpose. If your AI-assisted content stays entirely inside your company (internal memos, private Slack summaries, internal wikis), that duty doesn't apply. Clear no.
For the chatbot disclosure duty (Article 50(1)): the trigger is that a natural person can interact directly with your AI system. Employees are natural persons. Nothing in the source guidance we've reviewed grants a blanket internal-use exemption from this duty the way it does for the publishing duty; an employee-facing, company-branded AI assistant that staff chat with meets the same basic definition as a customer-facing one on its face.
We're not going to overstate this into a confident "yes, internal chatbots definitely need a disclosure": the Commission's guidance we've reviewed doesn't explicitly address the internal-use scenario, and enforcement priorities plausibly differ for wholly internal tools versus customer-facing ones. But we also won't tell you it's clearly exempt, because nothing in the verified material says that.
Practical, honest guidance: don't assume an internal chatbot is automatically outside scope. If it's cheap to add the same disclosure pattern (a first-message notice, a persistent badge) to an internal tool as to an external one (and it usually is), there's little reason not to, until the final guidelines settle this specific question one way or the other.
If your internal tool also touches customer data or produces content that later gets published externally (a support-macro generator whose output ends up in customer-facing replies, for instance), treat it as customer-facing from the start rather than internal, since the "internal" framing stops applying the moment its output leaves the building.
