RTK AI

RTK, short for Rust Token Killer, is an open-source CLI proxy for AI coding workflows. It filters and compresses command output so your AI assistant gets only the important parts, not the extra clutter. The main goal is to help people use AI coding tools more efficiently without changing how they work.

Key Features

• Compresses command output before it reaches the AI context window.
• Reduces token usage by 60-90% on common developer commands.
• Works with many AI coding tools, including Claude Code, Cursor, Gemini CLI, Aider, Windsurf, Cline, and Copilot.
• Open-source, written in Rust, and designed for local-first use with no telemetry.

Use Cases

• Developers who want to cut AI token costs during coding sessions.
• Teams using AI assistants for terminal commands, tests, and git workflows.
• Users who want longer AI sessions with cleaner, shorter command output.
