How were these 16 companies chosen?
- The company named the chatbot in public. The source is the company's newsroom, a vendor case study, or trade press.
- The source says what the chatbot does. Vague claims about "AI-powered service" did not qualify.
- Any number comes from that source. An entry with no published number says so.

Customer service assistants with published details
1. Bank of America
- What the chatbot does: Erica answers account questions and sends proactive insights, such as a cash back deal that matches a client's spending or a warning about where a balance is heading over the next 7 days.
- Published result: Erica has served nearly 50 million users and passed 3 billion client interactions. It averages more than 58 million interactions a month, and more than 98% of users find the information they need.
- Human handoff: Clients can schedule an appointment through Erica, which Bank of America describes as a handoff to its high-touch service channels.
- Pattern to copy: Erica draws on a library of more than 700 responses and has had more than 75,000 updates since launch. A chatbot needs steady maintenance after it goes live.
2. Lyft
- What the chatbot does: The assistant resolves thousands of customer requests each day. Anthropic's case study lists charge disputes and ride issues for riders, and onboarding questions for drivers.
- Published result: Lyft reports that average customer service resolution time fell by 87%.
- Human handoff: The assistant directs the customer to a human specialist when more hands-on help is needed.
- Pattern to copy: Measure resolution time before launch. Lyft could report a clear result because it had a baseline.
3. Klarna
- What the chatbot does: The assistant handles refunds, returns, and payment questions in 23 markets and more than 35 languages.
- Published result: In its first month the assistant held 2.3 million conversations, two-thirds of Klarna's customer service chats. Resolution time fell from 11 minutes to under 2 minutes, and repeat inquiries dropped 25%. Klarna estimated a $40 million profit improvement for 2024.
- Human handoff: In May 2025 Klarna began recruiting human agents again. CEO Sebastian Siemiatkowski said it is "so critical that you are clear to your customer that there will be always a human if you want".
- Pattern to copy: Do not judge a chatbot on cost alone. Klarna's CEO said cost had been "a too predominant evaluation factor" and that quality suffered.
4. Amtrak
- What the chatbot does: Julie helps travelers book rail travel by prefilling the booking form and guiding them through the remaining steps. She also answers questions such as which items are allowed on a train.
- Published result: Julie answers over 5 million questions a year. The vendor's case study reports an 8x return on the investment and 30% more revenue per booking made with Julie.
- Human handoff: The case study does not describe one.
- Pattern to copy: Let the chatbot fill in the form. Julie collects the trip details in conversation and passes them to the booking tool.
5. Marriott
- What the chatbot does: Guests text ChatBotlr to request hotel services or ask about the property. Rewards members use the Messenger and Slack chatbots to research and book stays at more than 4,700 hotels.
- Published result: Early findings showed 2 out of 3 Aloft guests interacting with ChatBotlr, with a five-second response time. Of the members who used the Messenger chatbot that year, 44% received stay-related customer service and 53% got help with their Rewards account.
- Human handoff: ChatBotlr connects guests to the front desk team. Rewards members can chat directly with Customer Engagement Center associates.
- Pattern to copy: Give the chatbot the routine requests so staff have time for the guests in front of them.
6. Amazon
- What the chatbot does: The tested agents handled two request types: return refund status and order cancellations.
- Published result: Amazon measured automation rate. That metric counts a success when the agent completes the request and the customer does not contact customer service again within 24 hours. The new agents "significantly outperform" the older rule-based ones. Amazon published no percentage.
- Human handoff: A request the automated agent cannot complete goes to a human customer service representative.
- Pattern to copy: Count a conversation as resolved only if the customer does not come back within a day.
7. Capital One
- What the chatbot does: Eno answers questions about recent transactions, balances, and due dates at any hour. It also sends alerts for a suspicious charge, a duplicate charge, an unusually large tip, and a free trial that is about to end.
- Published result: Capital One's article gives no usage numbers.
- Human handoff: The article does not describe one.
- Pattern to copy: Alert the customer before they have to ask. A duplicate-charge alert removes a service contact.
8. KLM
- What the chatbot does: BB helps customers book a ticket in conversation, without a KLM agent.
- Published result: KLM published no figures for BB alone. At launch, its social media service team handled more than 16,000 cases a week in nine languages.
- Human handoff: BB is backed by 250 human service agents and refers customers to them when it cannot help further.
- Pattern to copy: Staff the handoff. KLM put its agent team in the launch announcement.

Ordering and shopping bots from well-known brands
9. Domino's
- What the chatbot does: The first version, in September 2016, let customers with a saved Pizza Profile repeat a recent order or track an order. In February 2017 Domino's opened the full menu to anyone, with no profile needed.
- Published result: The announcements give no chatbot figures. Domino's said digital channels produced over 50% of its US sales at the end of 2015.
- Human handoff: Not described.
- Pattern to copy: Start with the repeat order. Domino's shipped reordering first and the full menu five months later.
- Source: Domino's investor relations, September 15, 2016 and Domino's press release, February 1, 2017
10. Starbucks
- What the chatbot does: Customers order and pay by voice or message, and can modify a drink the way they would with a barista. Starbucks also released an Alexa skill for reordering a usual item.
- Published result: None. The beta opened to 1,000 iOS customers, with a wider rollout planned through summer 2017.
- Human handoff: Not described.
- Pattern to copy: Test with a small group. Starbucks limited the first release to 1,000 customers.
- Source: TechCrunch, January 30, 2017
11. Sephora
- What the chatbot does: Reservation Assistant books makeover appointments at Sephora stores. Color Match scans a photo and returns the closest lipstick shade from Sephora's range.
- Published result: The launch coverage gives no figures.
- Human handoff: The booking leads to an in-store makeover appointment.
- Pattern to copy: Use the chatbot for the booking step. A short conversation replaces a longer form.
- Source: Retail Dive, November 3, 2016
12. eBay
- What the chatbot does: ShopBot is a shopping assistant for eBay's one billion listings. A shopper describes an item by text, voice, or photo, and the bot asks follow-up questions before it recommends listings.
- Published result: None published in the announcement.
- Human handoff: Not described.
- Pattern to copy: Ask a clarifying question before answering. ShopBot narrows the request first.
- Source: eBay Inc., October 17, 2016
13. H&M
- What the chatbot does: US customers answered multiple-choice questions about their style, and the bot sent outfit and product suggestions. A tap on an item opened H&M's mobile site.
- Published result: None published.
- Human handoff: Not described.
- Pattern to copy: Offer buttons as well as free text. Multiple-choice answers keep the conversation inside what the bot can handle.
14. Whole Foods
- What the chatbot does: Customers search recipes by keyword, by cuisine, or by emoji. Sending a jalapeno emoji returns recipes that use jalapenos. Conversable built the bot.
- Published result: None published.
- Human handoff: Not described.
- Pattern to copy: Train the chatbot on content the company already owns. Whole Foods used its recipe database.
- Source: VentureBeat, July 12, 2016
15. Fandango
- What the chatbot does: The bot gives movie information, trailers, showtimes, and nearby theaters, with a link to buy tickets on Fandango.
- Published result: None published. The announcement set the launch for May 2016.
- Human handoff: Not described.
- Pattern to copy: Answer the question, then link to the page where the customer completes the task.
16. Mastercard
- What the chatbot does: The plan was for US consumers to ask the Mastercard KAI bot about their accounts, purchase history, spending levels, and cardholder benefits on Facebook Messenger. A second bot for merchants would let shoppers check out with Masterpass.
- Published result: None. The report covers an announcement, with consumer access planned for early 2017.
- Human handoff: Not described.
- Pattern to copy: Build on a specialist platform when the subject is regulated. Mastercard partnered with a banking AI vendor.
- Source: Finextra, October 25, 2016
What do these companies have in common?
- The chatbot answers from the company's own data. Erica reads account data. Julie answers from Amtrak's travel information. Whole Foods used its recipe database. This grounding method is called retrieval-augmented generation.
- The scope started narrow. Amazon tested two request types. Domino's started with repeat orders. Starbucks opened to 1,000 customers.
- A person stays reachable. Lyft, KLM, Marriott, Amazon, and Klarna each describe a handoff. The comparison of AI chatbots with human handoff shows how tools pass the conversation on.
- Someone measures it. Lyft tracks resolution time. Amazon tracks whether the customer returns within 24 hours. Klarna tracks repeat inquiries.
Which example should your business copy?
If you need... | Copy... | Why |
Answers to repeat questions from pages you already have | Amtrak | Julie answers travel questions and fills in the booking form. |
Faster resolution on a large volume of requests | Lyft | The assistant resolves routine requests and people take the rest. |
Answers about a customer's own account | Bank of America or Capital One | Both connect the assistant to account data. |
Fewer front desk or phone requests | Marriott | ChatBotlr takes routine requests by text. |
Repeat orders in one message | Domino's | A saved order is the simplest transaction to automate. |
Product discovery in a large catalog | eBay or Sephora | Both ask questions first, then recommend. |
A clear rule for when a person takes over | Klarna | Klarna now promises a human whenever the customer wants one. |

How can a smaller business get the same result?
- List the 20 questions customers ask most.
- Check that each one is answered on a page, in a help article, or in a document.
- Train the chatbot on that content and test it with the 20 questions.
- Set the rule for when a person takes over, then test the handoff.
