BoltAI is a native macOS application built with SwiftUI and AppKit rather than a wrapped web page, which shows in its responsiveness and in details like universal shortcuts and Apple silicon performance. The core idea is consolidation: instead of juggling browser tabs for ChatGPT, Claude and Gemini, you configure each provider once and switch between more than 300 models from a single window, including local models served through Ollama or LM Studio.
Beyond chat, BoltAI leans into power-user workflows. Projects and multi-chat threads keep long research organised, chats can be forked to explore alternative directions, reusable agents carry custom instructions, knowledge and tools, and MCP servers can be connected and toggled per agent. Multimodal support means you can attach PDFs, screenshots or code and ask for summaries, explanations or structured extraction. A global hotkey pops the app over any window, while screen capture, dictation and inline editing keep you in the flow of whatever else you are doing.
Privacy is a structural part of the design: conversations are stored locally and not used for training, and API keys can be encrypted with a passphrase. Licensing is a one-time purchase with a year of updates, after which the installed version keeps working on your Mac. Older chats remain available while cloud sync and mobile access pause if you do not renew.
