A LangChain-compatible chat model that extracts responses via UI automation

UI Chat Model (ChatUIBridge)

A LangChain-compatible chat model that extracts responses by automating a web UI via Playwright.

Installation

pip install ui-chat-model
playwright install chromium

Usage

from ui_chat_model import ChatUIBridge

# Initialize the model pointing to your hosted UI
model = ChatUIBridge(
    url="https://your-frontend-url.com",
    model_name="llama-3.1-8b-instant"
)

# Use it like any other LangChain chat model
response = model.invoke("Hello, how are you?")
print(response.content)

How it works

This library uses Playwright to open a browser, navigate to a specified UI, type the prompt into a textarea, and extract the resulting text from the UI. It's designed to bridge web-only AI interfaces into LangChain workflows.
