Updated March 27, 2026
Overview
BLACKBOX AI is an AI coding assistant featuring 300+ models, autonomous agents, and multi-modal capabilities. Its CyberCoder autonomous agent handles complete multi-step development tasks independently—implementing features, refactoring codebases, fixing complex bugs, and completing projects from high-level descriptions. BLACKBOX AI supports 35+ IDE integrations including VS Code, JetBrains, Android Studio, and Xcode, plus a CLI agent for terminal-based development. It also offers image-to-code conversion, voice coding, and code extraction from videos.
Open-source desktop app for running multiple coding agents in parallel, each isolated in its own git worktree.
