Same prompt, same model: plain Claude Code, then with prismantis. ▶ Watch the full 49-second tour (chat layout, tables, charts, diagrams, pie charts, diffs, callouts).

TL;DR

- Claude Code prints mermaid as source and tool calls as walls of text. prismantis draws them: real charts and flowcharts, typeset LaTeX math in kitty and Ghostty, colored tables and code, and quiet tool rows.
- 16 palettes plus mono, and copy buttons on everything.
- Two commands to install, /plugin to turn it off. Claude Code's own renderer comes back the moment you do.
- No network calls. It runs a program only when you click ⧉ html or ▣ png (the clipboard helper) or turn on LaTeX (RaTeX's renderer).

Then run /prismantis setup to pick a theme and styles from drawn samples, and /prismantis demo for a tour of the main features. In a terminal, setup opens a pane: the arrows or Tab move through the styles of a step with a preview of the one in focus, Enter saves it and shows the next step. Where the session has no terminal, as in the desktop app, it walks the same steps in the transcript.

Install

Requires Claude Code 2.1.287 or later. Run the two commands above.

To update, run this, then /reload in every open session. A session keeps the version it loaded until it reloads.

To uninstall:

For LaTeX math, install RaTeX's renderer and set latex to true; see LaTeX math. Until then formulas draw as text.

Codex

prismantis also runs in Codex, with themes for code, tables and diagrams and the same session note. Install, what works today, and the two Codex issues it waits on for parity: codex/README.md.

OpenCode

prismantis also runs in OpenCode 2.2.5 and later, where it draws figure blocks in…
