An AI-powered coding assistant designed to help developers write code faster.

4.3/5 across SourceForge and G2 · 126 ratings, Sep 2026

Kite was an AI-powered code completion tool that provided intelligent suggestions while developers typed in their editor. It used machine learning trained on open-source code to predict completions for Python, JavaScript, and other languages. Kite supported integrations with VS Code, IntelliJ, PyCharm, Sublime Text, Atom, Vim, and Jupyter notebooks. A key feature was Python type inference from real-world usage data, plus inline documentation lookup. Kite reached a large user base but shut down after failing to find a sustainable business model, as individual developers proved unwilling to pay for code completion tools. Other tools later succeeded in the same space.
