TokenSaver is a local context optimizer for Claude Code, Codex, Gemini, Grok, and other AI coding tools. It reduces repetitive logs, searches, file reads, and tool output before they consume paid model context. Unlike command-specific reducers, it provides one cross-client proxy, a native Rust engine, fail-open processing, adjustable profiles, and evidence reports showing measured savings, overhead, failures, and per-client results. Windows, macOS, and Linux; free for personal home use.
