ConvoArk

A Chrome extension for saving AI conversations

ConvoArk is a Chrome extension that saves your ChatGPT, Claude, and Gemini conversations as a single HTML file you can open offline. Formatting, code, math, images, and citations stay intact, so you can read them again later or organize them as reference material.

How it started

While using AI to learn new fields, we struggled to find a tool that kept conversations, with their formatting, math, and citations, on our own computer. ConvoArk was born to solve that problem.

Key features

• Works with ChatGPT (chatgpt.com), Claude (claude.ai), and Gemini (gemini.google.com)
• Keeps formatting, code, math, images, and citations
• Save only the messages you want to keep; export to Markdown or PDF
• Interface in 日本語, English, 简体中文, and 繁體中文
• Conversation text is processed in your browser and is not sent to external servers
• No account or sign-up; no analytics; no ads
