ChatGPT in your pocket: the underrated version.
Most ChatGPT advice assumes you're at a keyboard. But the phone app has three abilities the website doesn't — your voice, your camera, and your location in the real world — and they change what the tool is for.
01 Voice is not dictation — it's conversation
Tap the voice icon and you're in a real spoken conversation — powered by GPT-Live, the full-duplex voice model, which means you can interrupt it mid-sentence like a person and it rolls with it. (Free accounts get the lighter GPT-Live-1 mini; it's still good.) Voice shines when your hands or eyes are busy: driving to a job and thinking through the estimate, walking and untangling a difficult email in your head, cooking while planning the week.
Voice mode is the best thinking partner mode. Say "let me talk through something — just listen and then tell me what you heard me decide." Rambling out loud at a patient listener that then summarizes you is worth the app all by itself.
02 The camera is a question box
Photograph it, then ask. This sounds like a gimmick until the first time it isn't:
- The error message on a screen → "what does this mean and what do I try first?"
- A dense contract page → "translate this clause into plain English."
- The breaker panel, the weird part, the warning light → "what am I looking at?"
- A menu in another language, a handwritten note, a whiteboard after a meeting → instant text.
One habit: photos of documents usually beat retyping them. Photos of situations usually need one sentence of context ("this is under my kitchen sink") to get a good answer.
03 Make it reachable in five seconds
04 What the phone is bad at
Honesty: long documents, serious writing sessions, and anything involving files belong on desktop. The phone app is for capture and quick answers — the thought you'd otherwise lose, the question that has a five-second window before you stop caring. Use each surface for what it's for.
Open the app, start a voice conversation, and talk through tomorrow's hardest thing for two minutes. Then say: "Summarize what I just said as a plan with three steps."

For one week, every time you'd normally photograph something to 'deal with later' — a document, a part number, a whiteboard — photograph it into ChatGPT instead and ask your question immediately. Count how many 'deal with later' items never became later-piles.
