ChatCache

ChatCache is a free Chrome extension designed to export ChatGPT conversations into multiple formats while preserving the original formatting, including code blocks, LaTeX math, tables, and images. It addresses the need for high-fidelity exports of AI chat interactions, making it possible to share, archive, or edit conversations without losing structural or visual details. The extension enables users to export chats in eight formats—PDF, Word, Markdown, HTML, plain text, JSON, CSV, and PNG—directly from a compact hover menu, requiring no configuration or sign-up.

One of ChatCache's distinguishing features is its pixel-perfect rendering of exported content, ensuring that code syntax highlighting, mathematical formulas, tables, and embedded images appear exactly as they do in ChatGPT. For lengthy conversations, the tool provides an outline side panel that acts as a table of contents, allowing users to jump between prompts and navigate large threads efficiently. The selective export functionality lets users choose specific messages—whether from themselves, the AI, or both—to include in the export, with real-time selection counts and presets for selecting or clearing all messages. This is particularly beneficial for archiving research threads, sharing relevant conversation segments, or focusing on AI responses only.

ChatCache is suitable for a wide range of users, including developers looking to save code snippets and technical explanations, students who need to export math-heavy study notes or research summaries, researchers archiving AI-generated insights, and writers preserving drafts or brainstorming sessions. The extension supports over 50 languages through locale catalogs and language settings, broadening its accessibility for users globally.

Most export formats are generated locally within the browser, with PDF creation utilizing a secure API. The extension emphasizes privacy, stating it does not use tracking or analytics. Users can provide feedback or report bugs directly from the side panel. ChatCache is available as a free Chrome extension and is tailored for those needing reliable, high-quality exports of their ChatGPT chat history for various workflows.
