Boltbar

Boltbar is a lightweight and open source chat utility designed specifically for Mac users who want fast, keyboard-driven access to large language models like GPT and Claude from anywhere on their desktop. It appears as a discreet chat bar that you can instantly summon with a simple keyboard shortcut, making it easy to query AI or get programming assistance without switching apps or breaking your workflow.

A standout feature is "agent mode," which lets you use AI code assistants, such as Claude Code or Codex, to perform tasks directly within the context of a project folder on your Mac. This mode can be strictly permissioned, so you control when the AI acts and what actions it can take, giving developers flexibility and peace of mind. The tool offers integrations for attachments, web search toggling, and supports both Apple Silicon and Intel Macs running macOS 13 or newer. Security and privacy are prioritized by keeping API keys in the macOS Keychain and storing chat history locally, with no analytics or external data sharing.

Boltbar is distributed under the MIT license and can be installed directly or via Homebrew, lowering the barrier for developers and technical professionals to start using it immediately. With simple navigation, theme options, and robust keyboard accessibility, it’s crafted for technical users who value speed, privacy, and fine-tuned control over AI interactions on their local machine.

Boltbar is designed for software developers, technical founders, and product managers who use macOS and want instant, keyboard-based access to GPT or Claude for coding help, technical questions, and project automation.

It especially suits indie developers and small technical teams who value quick workflows and local control, prefer native Mac experiences, and require privacy with no external data sharing. Users who frequently switch contexts or need AI programming agents working within their own project folders will find the agent mode valuable.

It's also an attractive option for anyone who dislikes heavy, Electron-based tools and instead wants a nimble, open source solution that isn't locked to a third-party service or platform.
