Request a data export from each AI you use, then convert the files into readable documents you store yourself. Each platform holds your history only while your account exists, so a backup means having your own copy: one folder of Word, PDF, Markdown or CSV files per platform, refreshed every few months.
Short answer
Request a data export from each AI you use, then convert the files into readable documents you store yourself. Each platform holds your history only while your account exists, so a backup means having your own copy: one folder of Word, PDF, Markdown or CSV files per platform, refreshed every few months.
Step by step
List the AIs you actually use: Most people have three or four: ChatGPT, one of Claude or Gemini, something at work like Copilot, and a research tool like Perplexity or NotebookLM. Back up the ones holding work you would miss.
Request each export: ChatGPT: Settings, Data controls, Export data. Claude: Settings, Privacy, Export data. Gemini: Google Takeout, select Gemini Apps. Copilot, Perplexity, Grok, Poe, NotebookLM and Google AI Studio each have their own route, covered in our per platform guides.
Keep the ZIPs, do not unzip them: Save each archive somewhere you back up already. Download links expire within about a day, so grab them promptly.
Convert each archive in the browser: Drop a whole ZIP onto the ChatExports converter. Conversations are read inside your browser tab, listed with titles and dates, and searchable across the whole archive.
Save documents and file them by platform: Download Word, PDF, Markdown or CSV per conversation, or a ZIP of everything, into a folder per platform. Markdown for searching later, PDF for anything you may need to show someone.
Repeat quarterly: Set a reminder every three months. Exports are snapshots, so anything created after the last one is not covered until you take a fresh one.
A backup is not a screenshot and it is not the chat sitting in your account. It is a copy you hold, in a format you can still open when the account is gone, the subscription lapsed, or the product changed.
Why the account is not a backup
Everything that can remove a conversation lives on the platform's side: a deletion with no undo, a second sign in method that splits your history across two accounts, a temporary chat that was never saved, a retention policy change, a lapsed plan. None of that touches a file on your own disk.
What each platform gives you
| Platform | Export route | Format |
|---|---|---|
| ChatGPT | Settings, Data controls, Export data | ZIP with conversations.json |
| Claude | Settings, Privacy, Export data | JSON archive |
| Gemini | Google Takeout, Gemini Apps | Takeout ZIP with HTML |
| Copilot | Microsoft account privacy dashboard | JSON or ZIP |
| Perplexity | Per thread export | Markdown or per thread files |
| Grok, Poe, NotebookLM, Google AI Studio | Platform specific, see each guide | Varies |
They all have one thing in common: the export is machine data, not something you can read. That is the gap the converter fills, turning any of these archives into a searchable list of conversations and then into documents.
A routine that survives contact with real life
One folder per platform, inside a folder you already back up
Quarterly reminder to re request exports
Markdown copies for searching across years, PDF copies for anything you may need to show a client, employer or court
Keep the original ZIPs alongside the documents, since they are the raw source if a format ever needs redoing
Two files per important conversation sounds excessive until you need to find something from eighteen months ago, at which point searching a folder of Markdown takes seconds.
The privacy part matters here
Backing up years of AI conversations means handling a lot of sensitive material at once: client work, medical questions, salary discussions, code from your employer. Every conversion here runs inside your browser tab, on your own machine. Files are never uploaded, never stored on a server and never seen by us, and closing the tab clears them from memory. That is the whole design, and it is why the conversion is safe to run on an entire history rather than only on the harmless chats.
Cost
Reading, searching and previewing every archive is free. Saving the documents is a one time unlock. Ten dollars covers ChatGPT only. Twenty five dollars covers all nine platforms, which is the one to pick for a real backup routine since you are almost certainly using more than one AI.
Frequently asked questions
How often should I back up my AI chats?
Every three months is a reasonable rhythm for most people, and before any account change, cleanup or cancellation. Exports are snapshots, so anything newer than the last one is not covered.
Which format should I keep?
Markdown for searching years later, PDF for anything you might need to show someone. Keeping both per important conversation costs nothing and saves a lot of time later.
Is my history uploaded during conversion?
No. Every archive is read inside your browser tab on your own device. Nothing is uploaded or stored, and closing the tab clears it.
Do I need the all platforms unlock?
If you use more than one AI, yes, the twenty five dollar one time unlock covers all nine. The ten dollar option is ChatGPT only.
