Keeping a conversation going can save time. The AI already knows the task, the decisions and the files.
The same history can also pull a new request towards an old answer. Starting again is useful when you want to remove that influence, not merely because the chat has become long.
Continue or start again?
You are revising the same draft
Continue. The history is useful.
The chat keeps restoring a rejected idea
Create a clean handover and start again.
The conversation is long but still focused
Length alone is not a reason to move.
Stay in the chat when the job is still the same
Continue when you are refining the same article, testing another version of the same plan or asking follow-up questions about the same document.
The history gives the AI useful context. You can refer to earlier decisions without repeating them.
Start fresh when the purpose changes
A new chat helps when you move to a different subject, audience or outcome.
For example, a conversation used to brainstorm a product may contain untested claims and rejected ideas. If you later need an evidence-led customer page, a fresh chat with the approved facts is safer than asking the old conversation to forget its own history.
Start fresh when the answer feels stuck
Repeated corrections can leave a conversation carrying too many competing instructions.
If the AI keeps returning to a rejected layout, tone or assumption, stop patching the prompt. Create a short handover containing the goal, agreed decisions, source material and remaining work. Use that in a new chat.
Do not copy the entire conversation. Carry forward only what still matters.
Use a project for work that will continue
A new chat does not have to mean losing the wider context. Keep related chats and files inside a project when the subject continues over time.
Each chat can then have a clear job while the project holds the stable instructions and reference material.
Run the clean-chat test
Ask yourself:
- Am I still working towards the same outcome?
- Do the earlier decisions still apply?
- Is the AI repeating something I have rejected?
- Would a new reader understand the current job from the latest messages?
- Can I summarise the useful context on one page?
If the history creates more confusion than value, begin again.
Use a handover prompt
Create a clean handover for a new AI chat. Include the goal, audience, confirmed facts, agreed decisions, source files, constraints, completed work and the next task. Exclude rejected ideas, repeated discussion and unsupported assumptions. Flag anything that still needs a decision.
Read the handover before using it. The AI may misunderstand which ideas were rejected.
Nova 9 view
Do not start a new chat simply because the old one is long. Start again when the purpose changes, the context has become confused or you need an independent view.
Take the decisions with you. Leave the clutter behind.
