ChatWise

ChatWise is a desktop AI chat application built around three ideas: simplicity, speed and privacy. Rather than juggling several browser tabs for different AI providers, you install one native app and talk to GPT-4, Claude, Gemini, DeepSeek, Llama and other models from the same window. The interface stays deliberately lean, with no feature bloat, and every interaction is optimised for the desktop experience rather than being a thin wrapper around a web page.

Privacy is the defining design decision. All of your chat history, attachments and settings are stored locally on your own machine and never leave the device, with the sole exception of the requests you explicitly send to your chosen LLM provider. That local-first architecture makes ChatWise attractive for people handling confidential material who still want the convenience of a consumer-grade AI chat client.

The feature set goes beyond plain conversation. ChatWise handles multimodal input including audio, PDFs, images and text files, renders artifacts such as HTML, React components, charts and documents, and adds real-time web search through Tavily's Search API or your local browser at no additional cost. With MCP support, the assistant can reach out to tools like Notion, Google Sheets and browsers to perform work on your behalf. It also integrates with existing AI subscriptions such as GitHub Copilot and Claude Pro/Max, letting you squeeze more value from plans you already pay for.
