Rendering

Let models draw charts & diagrams

Adds a hint so models can emit mermaid diagrams and chart blocks, rendered inline. Markdown tables always render.

Tools function calling

Let the model call tools

Only tool-capable models (e.g. gpt-oss, qwen3-coder) use these. Built-in tools run code, do math, and fetch URLs in a sandbox. You can also connect your own remote MCP servers — they're reached directly from your browser (the server must allow cross-origin requests from manticthink.com; tokens stay in this browser).
