Integrated in-IDE Chat - By deeply understanding your codebases, Refact.ai provides relevant, intelligent answers to your questions—right inside your development environment.
-
Integrated with the tools - Refact.ai goes beyond codebases, connecting with GitHub, GitLab, databases (PostgreSQL, MySQL), Pdb, Docker, and any shell command, so AI Agent can autonomously complete tasks—from code generation to deployment.
- State-of-the-Art Models - Refact.ai supports Claude 3.5 Sonnet, GPT-4o, and o3-mini, allowing you to choose the best model for each task based on its complexity.
-
Bring your own key (BYOK) - Use your own API keys for external LLMs, ensuring flexibility and control over your AI infrastructure.
- Upload images: Click the image button to add visual context to your chat.
- Use @-commands to control what context to use to answer your question:
Deploying Refact.ai Agent is like adding a 24/7 engineer to your team—one that instantly understands your codebase, adapts to your workflows, accelerates development from day one, and becomes a shared knowledge base for your entire team.
- Refact.ai already understands your company's context: AI Agent captures the unique structure, tools, and workflows of your organization, using your company's databases, documentation, and code architecture to deliver customized solutions.
- Gets smarter over time: With each interaction and feedback, Refact.ai Agent adapts to your organization's needs, becoming more accurate and powerful.
- Organizes experience into the knowledge base: Refact.ai Agent captures and shares knowledge from interactions with each team member. It not only streamlines workflows but also supports faster onboarding and smoother cross-functional collaboration across projects.
- Deploy Refact.ai on-premise: on your own servers or private cloud. Your data never leaves your control. Telemetry from the plugins goes to your server and nowhere else. You can verify what the code does, it's open source.
- Fine-tune a model on your codebase: A fine-tuned code completion model will provide you with more relevant suggestions: it can memorize your coding style, the right way to use your internal APIs, and the tech stack you use.
- Priority Support: Our engineers are always available to assist you at every stage, from setup to fine-tuning and beyond.
