ChatShell (https://github.com/chatshellapp/chatshell-desktop) — open-source desktop AI agent built with Tauri 2 + Rust. Ships with 9 built-in tools (web search, bash, file read/write, grep, etc.) so the AI can take real actions from the first conversation. No plugins, no config. Supports 40+ providers, MCP with OAuth, and a skills system. Apache 2.0.
Today working on adding chat history search (FTS5) and OpenRouter Nano Banana 2 support.
Been using ChatShell as my daily driver for non-dev tasks — research, writing, file management, web lookups. The features I rely on most are well tested through dogfooding.
