Your Chats Are Yours. Download Them Once a Year.
If you use AI most days, download your chat history once a year. I'd do it in the first week of January, next to backing up the photos.
In there you'd find the cover letter drafts and the late-night question about the lump. You'd also find the business idea you talked through for three hours and never wrote down anywhere else.
Your chat history is one of the most detailed records of your own mind that exists, and it's a diary kept in someone else's house. A company keeps it on its servers, the computers where it stores your data. A year of your thinking shouldn't depend on those servers, a password you might lose, or a product that might not exist in 2030.
ChatGPT and Claude will both hand you a copy, but almost nobody asks for one.
- Ask each tool for a copy. This copy is called an "export". Open Settings, find the privacy or data section and look for "export data". Confirm, and a download link arrives by email. The link stops working after a short while, so download the file when the email lands, not at the weekend. Menus move, so check each tool's help page for the exact clicks today. The point is that the export exists, and it's free. If you switched tools last year, export from both.
- Open the zip file when it arrives. A zip is a bundle of files squashed into one. Inside is your whole history, usually as a big text file in a format built for computers. Next to that sits a readable version that opens in a web browser. The readable version is fine for searching, though it won't look like the app. A year of chats can run to a few hundred megabytes.
- Lock it away. This diary is more personal than your photos, because it holds your health worries, your money, your arguments and probably other people's names. Keep it where you already keep private things, like an encrypted drive (one scrambled so only your password opens it) or a password-protected folder on your own computer. Never put it on a shared drive or a free file-sharing link. Name it with the tool and the date, for example
claude-export-2026-10.zip. - Read it like a diary. Search the readable version for "idea", "plan" and "should I", and you'll find things you'd forgotten you'd worked out. Maybe it's a pricing decision, a draft of the difficult email, or the outline of something you never finished. Copy the few that still matter into a fresh document, or put them in a Project if you want the AI to have them. Those few pages, chosen by you, are your real knowledge base.
One thing I wouldn't do is upload the whole file into another AI tool "to analyse it". That hands a year of your private life to a new company in one go, and most of it isn't useful anyway.
The export is only a copy, so downloading it removes nothing from the company's computers.
Deleting is a separate setting and a separate decision. The same area usually lets you clear out old chats you'd rather not keep there. Also, the copy only holds what your account still has, so chats you deleted along the way are gone.
Read a few of the old ones for their own sake. The person asking those questions a year ago is a good reminder of how far you've come, and of the worries that never happened.
They keep the servers. You keep the diary.
