peekme open-sourced: Trigger inline explanations by highlighting text in terminal outputs like Claude Code

Open-source terminal tool peekme allows users to highlight text in outputs from tools such as Claude Code, Codex CLI, and GitHub Copilot CLI, instantly triggering inline explanations via hotkeys. The tool expands an explanation box directly below the current line in the terminal, supports multi-turn nested queries, and leverages the authenticated client's model and session context—eliminating the need for separate API key setups or repetitive prompting. The project is open source and supports multiple installation methods, including npm, Homebrew, and Cargo.
