Chatbox Integration

AVELIN API works seamlessly with Chatbox — a cross-platform desktop AI client available on Windows, macOS, Linux, iOS, and Android. Chatbox provides a polished, native chat experience with support for OpenAI-compatible APIs.

Why AVELIN + Chatbox? A sleek desktop client that runs on every platform, connected to AVELIN's frontier models with 1M-token context windows — all with your own API key.

Chatbox is a cross-platform desktop AI client with native apps for Windows, macOS, Linux, iOS, and Android — the same polished experience on every device you own. It connects to any OpenAI-compatible API and provides a clean, modern chat interface with features like markdown rendering, code syntax highlighting, conversation export, custom system prompts, and image generation support. Your API keys and conversations sync across devices so you can start a conversation on your phone and continue on your desktop.

The killer feature is genuine cross-platform parity with a native feel on each OS. Most AI chat apps are either web-only or Mac-only; Chatbox ships real native clients everywhere. The mobile apps aren't afterthoughts — they're first-class experiences with the same model management, prompt templates, and conversation history as the desktop versions. It's for people who live across multiple devices and want one AI client that follows them everywhere without resorting to a browser tab.
