CloseChat

A multi-platform AI chat client that connects to any model you choose

Bring your own model provider

Configure the AI providers or API keys you already use, and switch between them inside the client instead of committing to a single bundled service.

Desktop and mobile cloud sync

Native apps for Windows, macOS, Linux, iOS and Android keep your conversations and settings aligned across devices.

All-format document understanding

Drag in PDF, Word, Excel, PowerPoint, code and image files and let the model summarise, extract or analyse the content directly.

Conversational image editing

Edit the same image across multiple turns, automatically carrying over the previous version and merging several images while keeping subjects consistent.
