What happened
Meta changed the terms of the WhatsApp Business Platform to bar general-purpose AI assistants. It was announced in October 2025 and has been in force since 15 January 2026.
This is not news this week. It is on this page because the coverage was written about ChatGPT and Perplexity, and a lot of business owners who run an AI agent on WhatsApp read it and were left wondering whether it was about them.
What the rule actually says
One new section in the terms, three phrases that carry all the weight.
“AI providers”
The terms gained a section on AI providers: companies that build AI models and want to distribute their assistant through WhatsApp. It is a rule about who is sending, not about whether AI is involved.
“General-purpose”
The target is an assistant that talks to anyone about anything — a chat partner, a question-answerer, a search engine in a chat window. Not an assistant that answers about one company's products.
“Primary functionality”
The ban applies when that general assistant is the main thing being offered. An AI feature inside a business's customer service is, by Meta's own description, a different thing. Meta says it decides what counts as covered, at its own discretion.
Who it affects
Mostly large AI companies, and in practice a handful of them.
OpenAI, Perplexity and Microsoft said their WhatsApp bots would stop working, and the services Luzia and Poke were affected too. Meta says the Business Platform was built to help businesses give customer support and send relevant updates. After the change, Meta AI is the only general assistant left on the app.
For a small or mid-sized business using AI to answer its own customers about its own products, orders and bookings, Meta has said that is not what the rule is for. The picture is still moving: regulators in the EU, Italy and Brazil have opened competition inquiries into the rule, so the text may change.
What is worth knowing
The rule is clear about the extremes and silent about the middle.
- Grey cases exist. An agent for a shop that also happily writes a student's essay or recommends a holiday starts to look like a general assistant. Meta has not published how it judges these.
- The decision is Meta's. The terms say it determines what is covered. A summary, including this one, is not the authority.
- Nothing about message pricing changes because of it. This is an eligibility rule, separate from the cost changes we covered elsewhere in this series.
- It is not a ban on AI. Businesses using AI to serve customers on WhatsApp are, in Meta's own words, unaffected.
What to do this month
Fifteen minutes. Three questions, asked about the agent you run.
- Whose assistant is it? If the agent is yours — built for your business, answering for your business — you are on the allowed side. If you are reselling someone else's general-purpose assistant under another name, you are not.
- What happens if someone asks it something off-topic? Message it from your own phone: ask for a poem, ask who won a match. An agent that politely returns to your business is behaving the way the rule expects.
- Does it do work only your business can do? Look up an order, book a slot, quote your prices. A bot that could do the same job for any company is the one to worry about.
- Write your scope into its instructions. One line saying it only answers about your business, and what to say when asked something else, closes most of the grey area.
- Read Meta's terms, not a summary. The AI providers section is short.
One thing not to do: do not switch your agent off over this. Meta has said plainly that AI for customer service is not what the rule targets.
How to read the next one
Platform rules change on the platform's timetable. A few questions sort out most of the noise.
- Who is it written for? A rule about AI providers is not a rule about the businesses that use them. Headlines usually blur the two.
- What is the exact test? Look for the phrases that carry the rule, and notice who gets to interpret them.
- What did the platform say it does not affect? Companies usually say it, and it is usually your case.
- Is it settled? A rule with open regulatory questions is a rule to re-read in six months.
The pattern to carry forward: WhatsApp wants to be a place where businesses talk to their own customers. Whatever you build on it is safer the more it looks like that, and riskier the more it looks like a product that happens to live in a chat window.
