How to save your ChatGPT, Claude and Gemini chats

Your best thinking is sitting in chat windows you will never open again. Here are the options for keeping it.

Copy and paste into a notes app

It works and costs nothing. The catch is that it relies on you remembering to do it, and formatting such as code blocks and lists often breaks on the way. After a month you have a folder of notes you cannot search by meaning.

Use each assistant's own export

Most assistants offer an account data export in their settings. It is useful as a backup. It is less useful as a working memory, because it is one giant dump per product and it does not include the other assistants you use or the pages you read.

Save to a private archive as you go

The most reliable habit is the smallest one: one click, right where the conversation happens. Stash puts a small pill on ChatGPT, Claude and Gemini. Click it and the thread is saved to an archive on your device, with its title, the date and the full text. Pages you read save the same way, so your questions and the sources behind them live together.

What to check in any tool before you trust it with your chats

• Where is the archive stored? On your device or on someone's server.
• Does it need an account? If it does, your chats are attached to an identity.
• Can you export everything to a file you keep, and delete everything on demand?
• Can you verify the claims? A local-first tool should stay quiet in your browser's network tab.

Stash is built around those four answers: on your device, no account, export and delete any time, and no network calls of its own.
