Naseem is a lightweight, native macOS AI agent written in Swift that goes beyond chat to take real actions on your Mac, including file editing, terminal commands, iOS Simulator control, and native app automation via Accessibility APIs. It supports major AI providers such as OpenAI, Anthropic, Gemini, and OpenRouter, as well as fully on-device inference via MLX, using your own API keys with no subscription required. Naseem keeps its prompt context small by collapsing completed tool outputs and supports sub-agent delegation, scheduled rules, cross-conversation memory, and Telegram remote access. A human approval gate governs consequential actions, and the app verifies outcomes rather than simply asserting completion.
