ChatGPT Mobile: 10 Hidden Features to Try Now

About this video

Kevin Stratvert demos the free official ChatGPT mobile app on iPhone and Android, focusing on phone-only uses. In real-time voice mode he points the camera at a German menu and ChatGPT identifies seafood options and explains item number 22 as a variation of herring prepared in two different ways with a house sauce. He then uses the same live conversation for real-time voice translation with a German-speaking customer at the fictional Kevin Cookie Company. The video shows customizing the voice in Settings under Voice Mode — he picks Maple after sampling several voices — and enabling background conversations so ChatGPT keeps talking with the screen off. Other demos: copy-pasting an email into ChatGPT and dictating a prompt to draft a friendly reply confirming an order and asking for delivery details; using the plus icon and Camera to add a T-Rex chasing him to a photo, generating two variations in seconds; asking by voice how to remove a chocolate stain from cotton for step-by-step instructions; attaching a 94-page PDF via Files and asking for a summary and key takeaways, which surfaces that customers prefer 6.3 chips per bite; and showing that chat history syncs automatically between PC and phone via the sidebar. He closes by switching models at the top of the screen to o3-pro, described as OpenAI’s newest reasoning model for ChatGPT Plus subscribers, which in his test reasoned for five minutes and returned a thorough, cited answer about launching a new cookie flavor and marketing it on YouTube.

Key takeaways

• Use real-time voice + camera mode to read and translate foreign-language menus and documents on the spot

• Attach files from the phone, including a 94-page PDF, and ask for a summary and key takeaways instead of reading it all
• Chats sync automatically across desktop and mobile, and Plus subscribers can switch to the o3-pro reasoning model from the model picker
