Gepetto

Gepetto is an IDA Pro plugin that connects to large language models to assist with reverse-engineering decompiled code.

Gepetto functions as a Python plugin for IDA Pro (version 7.6 or higher) that interacts with various large language models. Users invoke the tool directly from the IDA pseudocode context menu or via hotkeys to explain function logic, add comments, or rename variables automatically. It supports a wide range of model providers including OpenAI, Anthropic, Google Gemini, Azure OpenAI, Groq, Together, Novita AI, Kluster.ai, and local models via Ollama or LM Studio. Configuration occurs via a local .ini file, allowing for custom providers to be added through Python modules. The plugin also includes a CLI interface for direct queries to the chosen language model.
