Updated March 10, 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.
Kiro is AWS's agentic coding tool, with an IDE, CLI, and web app that turn prompts into specs, designs, and task lists before writing the code.
