If you use ChatGPT on your iPhone, you no longer have to keep one long, messy thread when your idea changes. OpenAI says branched chats now work on iOS, so you can split a conversation at any point and continue in a fresh chat without losing the original.
That matters because most real conversations drift. You start with one question, then you remember a second task, then you want a different tone or outcome. Branching lets you keep your place and still explore a new direction.
What “branched chats” actually do
Branching creates a new chat that starts from a specific message inside an existing conversation. Your original thread stays intact, and the branch becomes its own separate conversation from that point onward. OpenAI introduced the feature on the web earlier this year, describing it as a way to explore different directions without losing your original thread.
Now, you can do the same thing on iOS, instead of copying text into a new chat or starting over.
How to use branching on your iPhone
You trigger the feature from the message you want to split from. After that, ChatGPT opens a new chat that carries the context forward from that spot.
Here are the quick steps:
- Open the chat you want to split
- Long-press the message where you want to branch
- Tap Branch in new chat
- Continue the new thread in the separate chat window
If you do not see the option yet, update the ChatGPT app and check again. Rollouts often arrive in waves, even after an announcement.
You will feel the difference fast
Branching helps when your chat turns into three different jobs at once. You can keep one branch for research, another for writing, and a third for follow-up questions, all anchored to the same starting point.
It also cuts down on scrolling. Instead of hunting for that one response from earlier, you can branch right where the useful part begins and keep moving.
Practical ways to use it
- Writing: branch for alternate headlines, ledes, or tones without rewriting your whole prompt
- Troubleshooting: branch from the same error log and test different fixes
- Planning: branch for different budgets, itineraries, or priorities
- Learning: branch for a simpler explanation, then branch again for a deeper one
OpenAI first shipped branching on the web on September 4, 2025. The iOS version now brings the same “fork the thread” workflow to your phone.
