Overview

• Official support: - pangu.js - pangu.py - pangu.go - pangu.java - pangu.space - Community support: - pangu.clj - pangu.dart - pangu.ex - pangu.objective-c - pangu.php - pangu.rb - pangu.rs - pangu.swift - pangu.skill

Install 為什麼你們就是不能加個空格呢？ and it spaces every page you browse. It also comes with the AI Spacing feature:

Regex rules can't distinguish semantic nuances like these, so the extension asks an LLM. It uses Chrome's built-in Prompt API, which runs Gemini Nano on your device. Fully offline, nothing leaves your machine. Needs a one-time model download from the options page. It's free, btw.

GPT-6 Astra writes the prompts. It runs the prompt-experiments skill: propose a change, then test it against the real Gemini Nano in Chrome. When a case fails, it interviews Gemini Nano for clues. When progress stalls, it searches online for new approaches to test. Prompts for a model, tuned by a bigger model, judged on real data.

Make sure to import from 'pangu/browser' in ESM, which is the DOM-aware build ('spaceNode()', 'autoSpacePage()') with matching TypeScript types and resolves correctly across all bundlers.

How it fits a local-AI stack

pangu.js runs on your own hardware, so pair it with a model and a GPU sized to your needs. Use the VRAM calculator to pick a model that fits your card, and see what you can run for hardware guidance. Related local-AI tools in the directory:
