Google Allo chat app is smart, but enough to break though

Google wants to add a middleman to your mobile chats -- a personal virtual assistant who's not shy about interjecting itself into the conversation.

The new Allo app promises to be "smart," sort of. Its Google Assistant will butt in with restaurant recommendations when someone types, "Want to get sushi " It can also send daily updates on weather and sports or suggest replies to your friends' messages.

The idea is to keep the conversation flowing, so you don't have to constantly leave Allo to look up something else.

Google is releasing the free chat app Wednesday, just a week after Apple updated its own Messages app with the iOS 10 software update. Messages works on iPhones and iPads, while Allo will work for iPhones and Android phones, but not tablets.

Do you really need another chat app Here's more on Allo to help you decide.

Personal assistant When you're chatting with someone, you're often making plans. Google Assistant can retrieve information on nearby restaurants, movie times and even the weather. Everyone in the chat will see the Assistant's replies and can weigh in on the choices.

In some cases, Google Assistant will even anticipate your needs, such as when someone's asking about getting sushi. An oval bubble appears with an offer to retrieve nearby sushi restaurants. After choosing one, you can tap for opening hours, directions or the menu. Beyond planning, Google Assistant can give you the latest news and sports scores, translate phrases or do math calculations. Asking for directions will bring up Google Maps.

Limited smarts The app's intelligence still feels, well, limited. Though Google Assistant is an evolution of the Google Now feature that has long been on phones, it doesn't do as much as Google Now in terms of identifying patterns or checking other Google services.

For instance, if a friend asks you when your flight leaves, Allo won't try to suggest a reply, even though Google has your calendar. Likewise, Google Assistant won't automatically offer traffic conditions or transit schedules for your regular commute the way Google Now does.

You can request daily updates on the weather, news and sports. But you can't get automatic updates whenever the score changes or a game ends. Google calls its Assistant a preview. Following its debut on Allo, it will arrive on a smart speaker called Google Home this fall.

Expressions Plain text is boring, so Allo features a slider that can make your messages and emojis larger or smaller. You can send one of hundreds of virtual stickers specifically designed for Allo. Apple's Messages app has a variation on this. You can make a message "loud," such that the chat bubble briefly gets larger. Or make it “gentle” and appear in small text. Sticker packs are also available through a new app store within Messages.

One problem with both of these apps is that your friends need to be using the same app to see the desired effect. Google will send text messages to non-Allo friends, but without the special effects. Apple Messages will add notations such as "sent with Loud Effect" to those on Android or older versions of Messages.

Smart replies Allo can help cut down on typing on small screens by suggesting replies based on context. If a friend asks how you're doing, you can tap "Good tnx." Allo preserves chatting shortcuts such as “u” for “you.”

Apple offers something similar on its smartwatch, but not phones or tablets. Allo will also analyze photos to suggest replies such as "beautiful smile" or "the skyline looks great!" — at least for photos with smiles or skylines. Remember that this is software, so its suggestions won't always make sense.
