After setting the record for the fastest-growing userbase, ChatGPT now sees over 25 million daily per the latest data. But despite such exceptional levels of popularity, the AI chatbot continues to lack an official app and is best accessible from the OpenAI website. That’s not to say that app stores are devoid of unofficial apps – they are actually brimming with those, but not all are trustworthy. In this article, we take a look at the fastest ways to access ChatGPT on your smartphone so that you can maximise productivity. Hey GPT replaces Siri with ChatGPT Released late last month, Hey GPT is easily one of the best ways to interact with ChatGPT on your iPhone. The tool is essentially a shortcut that ‘replaces’ Siri with ChatGPT on iPhones and iPads. When it’s activated, you’ll be able to get the bot to write you emails, suggest recipes, and explain complex topics, using basic prompts of just a few words. And unlike other ChatGPT tools, Hey GPT even responds in Siri’s voice. Of course, it will not be as fast as Apple’s voice assistant, but it’ll be able to do so much more. To activate it you’ve to first install the extension from this link, enter your OpenAI API key after getting it from here, and add the shortcut to home. You can then start using it immediately. BuddyGPT adds ChatGPT to your WhatsApp If you are a WhatsApp user, chances are you use it more than any other app on your phone. To add ChatGPT to WhatsApp, visit this link. BuddyGPT is a service that allows you to use ChatGPT on Whatsapp and Telegram. Once you’ve opened the link, you will land on the chat interface on the messaging app. Here, you’ll be asked to select the language. Select English and begin chatting with ChatGPT almost as if they’re a friend on WhatsApp. Just note that BuddyGPT only allows 15 messages per month for free before it asks to subscribe to the premium tier. Microsoft Start is an actual ChatGPT app Microsoft Start is an all-in-one search app that offers a number of utilities. It is now also powered by the new Bing AI, which is based on GPT-4. The app is the closest you can get to using ChatGPT as an app officially. After you’ve downloaded it on your Android or Apple device, just hit the Bing logo at the centre of the bottom toolbar to begin chatting with GPT-4. You can also select from one of three conversational styles here – Creative, Balanced, and Precise – based on your needs. As an additional perk, Bing can serve up information on current affairs since it has internet access, unlike ChatGPT. SwiftKey brings ChatGPT to all apps The SwiftKey keyboard remains the most accessible way to ChatGPT (GPT-4) on your smartphone, allowing you to summon the AI chatbot on any app. You can download it from the Play Store and App Store. Once downloaded, open the app and set SwiftKey as your input method. Next, open up any chat, notes, or email app and fire up the keyboard. On the top-right of the keyboard, you’ll see the Bing logo. Tap it and switch to Chat mode to start talking with GPT-4. The Bing AI integration on SwiftKey can also help “if everybody’s cracking jokes in the chat and you need a clever pun, or you’re new to the area and are texting some new friends to propose a good local restaurant,” according to Microsoft.
