AI Commentary
Replit Ghostwriter uses a combination of OpenAI and proprietary models to power code completion, chat, and code explanation features within the Replit IDE. Its deep integration with the Replit runtime means the AI can understand and interact with your running program directly. Ghostwriter is particularly strong for education and rapid prototyping scenarios where setup friction must be zero. Replit's AI Agents feature can now autonomously scaffold entire projects from a prompt.
JetBrains AI Assistant leverages both OpenAI and Google models, intelligently selecting the best option for each task type such as code completion, explanation, or test generation. Its deep IDE integration means the AI has rich context about your project: frameworks, dependencies, and code style are all factored into suggestions. JetBrains is developing its own AI models to reduce reliance on external providers. The assistant is best suited for developers already committed to the JetBrains ecosystem.
