Inbox AI

Inbox AI is a macOS application that enables users to interact with artificial intelligence through both voice and text input, while also automating tasks and processing emails. The software integrates with over 13 different AI providers, allowing users to choose the underlying model that best fits their needs—whether that is a cloud-based API or a free, local on-device AI. This flexibility means users can maintain privacy by running models locally, or leverage powerful external APIs for complex tasks. The core functionality revolves around building custom voice assistants that behave like a combination of Siri and Zapier. Users can create assistants with specific instructions and capabilities, such as drafting emails based on spoken or typed commands, remembering factual information mentioned during conversations, discussing text visible on the screen, rewriting selected text, replying to messages, searching the web, fetching and summarizing web pages, opening applications, running macOS shortcuts, using MCP (Model Context Protocol) tools, branching workflows based on conditions, and transcribing audio into text. Each assistant can be tailored with its own system prompt and set of authorized tools, making it possible to automate repetitive workflows or provide on-demand information retrieval without manual intervention. The application also processes emails, enabling users to have conversations with AI about their inbox, draft responses, categorize messages, or extract action items. All interactions can be initiated through voice commands, which are transcribed and sent to the chosen AI provider for processing. The results are then read back or displayed. Users can also trigger automations via text input when voice is not appropriate. Inbox AI operates entirely on the
