Refact.ai is a cloud-based AI coding assistant that offers per-user analytics. It provides rapid code completion and robust code improvement tools. Users have the option to download plugins for JetBrains or VS Code. Refact supports multiple code language model (LLM) options such as GPT-4, Code LLama, StarCoder, and WizardCoder, allowing users to select the model that best suits their requirements. The tool comprehends the context of the codebase using its fill-in-the-middle technique and offers privacy-conscious options, including self-hosted versions. Refact aids users in auto-completing lines of code, refactoring, analyzing, debugging, and addressing code-related queries through chat.
