AI Chat Toolkit – AI Chats Export, Prompts, Timeli by HeroBlast

CopyTeX enhances your AI chat experience with four powerful tools that work seamlessly across all major AI platforms.

✦ Export Chats to Markdown

Download any conversation as a clean .md file — with LaTeX math preserved as $...$ / $$...$$, code blocks intact, and files named by conversation title and date. Use Export All Chats to batch-download your entire history as a .zip archive.

✦ Conversation Timeline

A compact, proportional navigation bar appears on the side of your chat. Each dot represents a user message — click to jump directly to that turn. Ideal for long, multi-turn research sessions where scrolling becomes tedious.

✦ Prompt Button

Save your frequently used prompts and insert them into the input box with one click. The button appears right next to the chat input, so your go-to instructions are always one tap away.

✦ One-Click LaTeX Copy

Hover over any math formula and copy the raw LaTeX source with a single click — no more manually transcribing equations. Works with KaTeX, MathJax, MediaWiki Math, and platform-specific renderers. Compatible with any website that renders math, including Wikipedia, Overleaf, and more.

Support various AI Platforms
