Texpop

texpop

*Hotkey LaTeX popup for Claude Code (and Codex, experimentally) — overlays your terminal, picks the focused chat, renders Markdown + KaTeX.*


**Press `Ctrl + Alt + V` in any Claude Code terminal session.** **The last assistant message renders as Markdown + LaTeX in a window that overlays the terminal exactly.** **`Esc` closes. Press the hotkey again to refresh with the latest reply.**

texpop is for the people who ask AI assistants to *derive* things, not just refactor them — students, researchers, anyone whose terminal output contains more `\sum` than `;`. The reasoning is already in your transcript on disk; texpop just renders it where it's legible. It's a **LaTeX parser for Claude Code** (and Codex, experimentally) for Windows Terminal, conhost, WezTerm, Hyprland, Sway, and the rest of the post-VS-Code world: KaTeX, focused-chat detection, DPI-correct overlay, fully offline.

Why this exists

Every existing LaTeX renderer for Claude assumes you live in a specific surface. VS Code extensions like `claude-code-katex` and MathRender only fire when you run Claude Code as a VS Code task — they're useless if you launch `claude` from Windows Terminal, conhost, WezTerm, or any other terminal. Tampermonkey scripts like `Claude-LaTeX-Parser` and `Claude-LaTeX-Math-Renderer` only target `claude.ai` in the browser — they never see the CLI. And **none** of them solve the harder problem: when you have several Claude Code chats open across tabs and panes, *which* one are you looking at right n
