There’s one big problem right now with Facebook Messenger bots

Facebook reported monster second-quarter earnings this week, and at one point on the investor call, CEO Mark Zuckerberg addressed all that the company is doing with messaging. After reminding investors that both Facebook Messenger and WhatsApp now have 1 billion users, Zuckerberg said, “The scale we’ve achieved with our messaging services makes it clear they are more than just a way to chat with friends.”

One of Facebook’s big recent efforts to prove that—that messaging can be for a lot more than messaging—is with bots inside Facebook Messenger that use artificial intelligence to talk to you like a person would.

Facebook first announced the bots at its big F8 conference back in April, and at the time, it made a big to-do over the rollout. “We think you should just be able to message a business in the same way you’d message a friend,” Zuckerberg said. He and Messenger chief David Marcus raved over the various exciting use cases of the new bots, from buying flowers to ordering an Uber to checking flight prices, all without leaving Messenger.

There’s just one problem with that vision: so far, the bots are useless almost across the board.

For the uninitiated: The way bots work is that you can send them a command or question and they respond, in a message, like a person would. (At least, that’s who they are meant to work, in theory.) At F8, when Facebook first touted the new bots, it specifically highlighted a select few “featured partners,” including shopping bot Spring and weather bot Poncho.

On Poncho, a character named Poncho the Weather Cat (yes) greets you by saying, “Hi, bb. Here’s your forecast.” The “forecasts” Poncho gives read like parodies. They are what someone would send you if they wanted to intentionally obfuscate the weather. Most of the report is devoted to a dumb joke or cuddly greeting.

Here’s a weather forecast Poncho gave me: “Chip-ping in: Yeah, low 50s temps are great, but I brought two salsas. I’m, like, 75% responsible for the success of this roof party.” And another: “Six umbrellas: All I need is morning rain, low 50s temps and a little ingenuity, and I can create my own waterpark! Take that, Six Flags!”

Another bot, PennyCat, has a similar cat mascot, and exists to help you find discounts on products. I started by trying, “discount on nespresso capsules.” PennyCat responded, “My little kitten brain didn’t catch that. But I’ve found a funny GIF for you!” You can probably guess what animal was in the GIF it sent me. Finally I realized you need to interact with PennyCat by typing a business—that is, search by typing “Target,” not “laundry detergent.” So I tapped “Check discounts” and then typed, “Nespresso.” That at least worked: PennyCat figured out what Nespresso is, but said it found no coupons. So there was a learning curve; if you type your question in just the right format, you might get the gift of an answer.
