Each description comes from the company's own website, re-checked today. Before you launch, my piece on why some AI chatbots lose five-star reviews covers the mistakes to avoid.

The transparency rule for customer service chatbots

Here's one to build in from the start. The European Commission's page on the AI Act says that when people use AI systems such as chatbots, they should be made aware that they're interacting with a machine so they can take an informed decision. If you serve customers in the EU, that's a reason to label your bot clearly.

It's good practice everywhere, too. Give the bot an obvious name or label, say it's an AI assistant in the first message, and always offer a clear way to reach a person. Customers are far more forgiving of a bot's limits when they know they're talking to one.

What makes a support chatbot useful

• Good source content. The bot can only be as accurate as your help pages and policies.
• A clean handover. Tricky or emotional questions should go to a person with the chat history.
• Clear limits. Tell the bot what it mustn't answer, such as refunds or legal questions.
• Regular review. Read real conversations weekly and fix the gaps.

Launching an AI chatbot in five steps

1. Collect your top questions from emails and chats.
2. Update or write help articles that answer each one clearly.
3. Train the bot on those pages only, not your whole website.
4. Set up handover to your team and test it on difficult questions.
5. Launch on one page first, then expand once answers look reliable.

Chatbot mistakes customers notice

• Pretending to be human. It backfires the moment the bot gets something wrong.
• No way out. Always offer a route to a person.
• Outdated answers. Old policies in the training content cause real problems.
• Forcing the bot on every page. Pop-ups on checkout pages can lose sales.

Decide up front which questions the bot will never answer on its own, such as complaints, cancellations or anything involving health or account security. Routing those straight to a person protects customers and your reputation, and it makes the bot better at the things it should handle.

Measuring whether the chatbot helps

Track the share of chats resolved without a person, how often customers ask for a human, and what they rate the answers. If you're thinking about automating more of your support, this guide to AI automation for customer service covers what works and what breaks.

Do you make AI chatbots or support tools? Tool makers can ask to be considered for a featured place on this list.

My plain advice on AI customer service chatbots

Start with the questions you answer every day and a small, accurate set of help content. A bot that answers twenty common questions well, and hands everything else to a person, will do more for customers than one that tries to answer everything.

And keep a person responsible for it. Someone should read conversations each week, fix wrong answers and update the content as your products and policies change.
