Does Article 50 apply to my Slack or Discord bot?

Yes if the bot replies to people. The Commission FAQ lists chatbots, AI agents, and avatars as systems that interact directly with people. A Slack or Discord bot that answers a mention, a DM, or a slash command with generated text is in. The 20 July 2026 guidelines also name AI bots on social networks and media as in-scope examples.

A one-way webhook is usually out of Article 50(1). The FAQ’s second criterion is a genuine two-way exchange, not merely collecting data or giving automated responses. A CI bot that only posts “build passed” and never talks back usually fails that test. You may still have Article 50(2) marks on any generated text the webhook does write.

The four FAQ criteria, applied to Slack and Discord

The Article 50 FAQ (last update 24 July 2026) lists four cumulative criteria for the interaction-notice duty. All four have to hold:

  1. The system is an AI system.
  2. It is designed for a genuine two-way exchange with people, not merely collecting data or providing automated responses.
  3. The interaction is direct: the AI itself communicates with the person, not through a human intermediary.
  4. The person is a natural person (consumer, professional, or other user).

A product that sits in a channel, answers “@bot what shipped this week?”, and keeps the thread going usually clears all four. A webhook that only dumps CI or calendar events, and never replies to a person, usually fails criterion (2) and the FAQ’s background carve-out.

What you shipped in the workspace

What you shipped Art. 50(1) notice? Why
Bot replies to @mentions, DMs, or thread questions with generated text Yes Direct two-way AI-to-person interaction. FAQ examples include chatbots and AI agents.
Slash command that asks a question and the bot answers Yes The person started a two-way exchange. The bot is talking, not a human intermediary.
Bot with a human display name and a photo avatar Yes, and treat “obvious” as out FAQ: identify a reasonably well-informed, observant person. A bot dressed as a colleague is the opposite of obvious. Read the exception restrictively.
One-way webhook: CI, deploy, or calendar posts. No talk-back Usually no under Art. 50(1) FAQ: not a genuine two-way exchange; automated responses / background / no direct contact.
AI drafts the reply; a human teammate hits send Usually no under Art. 50(1) FAQ: not direct when it goes through a human intermediary.
US company, EU staff or EU customers in the workspace Still in if the other criteria hold FAQ: third-country providers are in if the output of the system is used in the EU.

Where Article 50(1) applies, people must be informed from the start of the first interaction, in a clear and distinguishable way, including accessibility. In Slack or Discord that is the first bot reply in that conversation (or persistent chrome on the bot), not a later workspace description, an #announcements post, or a privacy policy.

Other Article 50 duties that still bite one-way bots

Article 50(2): providers of systems that generate synthetic text must mark that text in a machine-readable format so it can be detected as AI-generated. Bot replies are synthetic text. A limited grace period exists only for systems already on the market before 2 August 2026: those marks are due 2 December 2026. The in-channel notice is a different duty and had no extra delay.

Article 50(3): if the bot does emotion recognition or biometric categorisation on messages or voice clips (sentiment, “who is angry”), deployers must inform the people exposed. That duty is independent of the chatbot notice.

Article 50(4) public-interest text: deployers must label AI-generated text that is published to inform the public on matters of public interest, unless it had real human review or editorial control. A private Slack thread is not that. A public Discord announcement about a political or consumer-safety topic might be.

Workspace terms, employment rules, and GDPR are separate from Article 50. This page does not cover them.

What is live this week

Article 50 applies from 2 August 2026. The 31 July 2026 Commission press says chatbots and other interactive AI systems have to tell users they are dealing with AI, not a human. The Digital Omnibus moved high-risk dates, not Article 50.

National market surveillance authorities enforce most Article 50 cases. Fines can reach €15 million or 3% of worldwide turnover, with proportionality language for SMEs.

Do this in seven days

  1. Inventory every Slack and Discord surface: @mention bot, DM bot, slash command, workflow step, incoming webhook, public server bot.
  2. If the AI replies to a person, ship a first-interaction notice in that conversation. Commission-style example used on this desk: “You are interacting with an AI system.”
  3. If it only posts one-way status, document why Article 50(1) is out (automated responses / no two-way exchange). Do not skip Article 50(2) marks on any generated text.
  4. Do not treat a human display name, a photo avatar, or “everyone here knows it is a bot” as obvious. The FAQ says read that exception restrictively.
  5. Do not put the only notice in the Slack workspace description or Discord server rules. The FAQ wants the start of the first interaction, clear and distinguishable.
  6. Open a 2 December marking ticket for pre-2 August products. If you run sentiment on messages, add the Article 50(3) exposure notice.
