What it does
fork ai turns a question into a branching research map instead of a chat log. Ask anything → structured answer split into sections → branch any section deeper, or highlight a sentence and follow up from that exact text.

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate).
