How to Export Your ChatGPT History — and Turn It into a Prompt Library

Can you export your ChatGPT history?

Yes. OpenAI lets every user download their complete chat history as a data export. What ChatGPT doesn't do is make that export useful: you get a raw JSON file, not a browsable prompt collection. This guide covers both halves — getting the export, and turning it into a working prompt library.

Step 1: Request your data export from ChatGPT

1. Sign in to ChatGPT (web or app) and open your profile menu.
2. Go to Settings → Data controls → Export data.
3. Confirm the request. OpenAI prepares the archive and emails you a download link (usually within minutes, though it can take longer for large histories).

Step 2: Download the archive

Open the email on the device where you want your prompt library — iPhone, iPad or Mac all work. Download the .zip; inside it, the file that matters is conversations.json, which contains every conversation you've ever had, including all your prompts.

Step 3: Import it into Vault in one tap

Vault: AI Prompt Library has a built-in importer for exactly this file format:

1. Open Vault and go to Profile → Import from ChatGPT.
2. Select your conversations.json (or the zip's extracted folder) in the file picker.
3. Vault parses the conversation mapping and creates a saved prompt from your messages — titles included — in seconds.

The import happens entirely on your device. Nothing is uploaded anywhere; Vault has no server and collects no data.

Step 4: Turn raw history into a working library

After the import, spend a few minutes curating:

• Delete the one-offs. "What's the capital of Peru" doesn't need to live forever.
• Tag and categorize the keepers — see our organizing system.
• Template the repeat performers. Any prompt you've re-used with small edits is begging for {{variables}}.

From then on, new ideas go straight into Vault — and any prompt can be launched back into ChatGPT, Claude or Gemini with one tap.
