ChatCache is a free Chrome extension that lets you save your ChatGPT conversations in any format you need. Whether you’re archiving research, sharing outputs with your team, or building a knowledge base, ChatCache exports your conversations with every code block, table, image, and LaTeX formula preserved exactly as it appears in ChatGPT.

​
What ChatCache does
