Chatbox

Clean desktop AI client for ChatGPT, Claude, and any OpenAI-compatible API

Introduction

Chatbox is a lightweight, open-source desktop AI client (GPL-3.0) that lets you connect any OpenAI-compatible API with minimal setup. TokenMix's API is fully compatible, so you can use Claude, GPT-5, DeepSeek, and more directly from the Chatbox interface on Windows, macOS, or Linux.

Prerequisites

• Download Chatbox from chatboxai.app or GitHub Releases. Install the version for your operating system.
• Sign up at tokenmix.ai and go to Console → API Keys to generate a key starting with sk-tm-.

Setup Steps

1. Open Chatbox and click the Settings button (⚙️) in the lower-left corner of the sidebar.
2. Under AI Model, click Add AI Provider.
3. In the provider type dropdown, select OpenAI API Compatible.
4. Fill in the fields:
   • Name: TokenMix
   • API Key: paste your sk-tm-xxx key
   • API Host: https://api.tokenmix.ai/v1
   • API Path: leave as default /v1/chat/completions
5. Click Add Model and enter the model ID, e.g. claude-sonnet-4.6.
6. Click Check to verify the connection — you should see a success confirmation.
7. Click Save and return to the main chat screen.

Verify

Start a new conversation, select TokenMix as the provider and your added model. Type a test prompt and confirm you receive a response.

FAQ

Q: The connection check fails with an authentication error. A: Verify the API Host is exactly https://api.tokenmix.ai/v1 (include /v1, no trailing slash). Copy the key fresh from the TokenMix console to avoid clipboard issues.

Q: I can't find the model I want. A: Add models manually in the model list. Use the exact short_id from the TokenMix models page, e.g. claude-sonnet-4.6, gpt-5.4, deepseek-v4-pro.

Q: Does Chatbox support mobile? A: Yes — Chatbox has iOS and Android apps. The same API Host and Key settings apply in the mobile app's Settings screen.
