How do I build a Claude-style chat app in Python?

This Reflex template reproduces the parts that make an assistant usable: a conversation list, a message composer, streaming replies, Markdown rendering for code and tables, and saved history. The chat UI is Python components you can restyle.

Can this connect to the Anthropic API, OpenAI, or a local model?

Yes. The template ships with a local response path so it runs with no credentials, and that boundary is a single function. Teams commonly swap it for Anthropic's Claude API, OpenAI, Google Gemini, or a self-hosted model and keep the same interface.

How do I stream responses and render Markdown in a chat UI?

Replies stream token by token into the active thread through Reflex state updates, and the message body renders Markdown, so code blocks, lists, and tables display correctly. Both behaviors are independent of which model produces the text.

How do I save and search conversation history?

Conversations are stored with titles and timestamps and can be renamed, searched, and deleted. History persists to SQLite by default; point the same models at Postgres when you need it shared across users.

About This Template

Build a production-ready Claude clone with Reflex and Python. This template is designed for developers prototyping a Claude-style AI chat experience who need a usable app structure for Claude-style chat, AI assistant, prompt workspace, and LLM application, not a static mockup. The app pattern includes a focused dashboard, searchable tables, detail views, validated forms, status-aware actions, empty and loading states, and database-ready state management. Use it as a starting point for a Claude chatbot, AI chatbot clone, Anthropic chat app, and LLM chat interface while keeping full control of the Python codebase.
