ClickUi

ClickUi is an open source desktop AI assistant written entirely in Python that brings chat and voice conversations with AI models to any computer, outside the browser. Pressing Ctrl+K anywhere opens a chat bubble where the user can type, attach files or talk, and the window can be hidden again with the same shortcut while a voice session keeps running. It is aimed at people who want one lightweight assistant that works with the model of their choice. It connects to OpenAI, Claude, Google, OpenRouter, Groq and Ollama, among others, so both proprietary and local models can be used. Speech recognition uses Whisper and speech generation uses Kokoro, and voice mode works with any configured model. Built in tools give every model that supports function calling live Google search and web scraping, including lookups of property values from Zillow and Redfin through text or voice. Transcribed speech is also copied to the clipboard, which lets ClickUi act as a voice input method for editors such as Cursor or Google Docs. It runs across platforms from the source code with a single Python command, and packaged executables are listed as coming soon. ClickUi is free, and its source is published on GitHub under the AGPL 3.0 licence. There is no paid plan; the project accepts donations through PayPal and Zelle, and users pay only for any hosted model APIs they connect.
