Sweep

Sweep is the specialized AI Coding Assistant engineered exclusively for the JetBrains ecosystem. It tackles the core developer challenge of integrating high-performance AI tools without sacrificing the deep functionality of their favorite IDE. By delivering an intelligent agent and instant, context-aware autocomplete, Sweep helps developers drastically accelerate their workflow, enabling them to write code up to 2x faster.

Key Features

Sweep leverages deep integration and specialized models to transform your development process directly within your IDE.

🧠 Integrated AI Agent for Codebase Mastery

The Sweep AI Agent is built to understand your entire project architecture. It can execute complex, multi-file code modifications, run necessary tests, and automatically identify and flag linter errors—all without you needing to switch contexts. This integrated approach ensures the AI acts as a genuine collaborator, not just a suggestion tool.

⚡ Next-Edit Autocomplete 

Sweep’s custom Tab model predicts your next coding intent with unmatched speed, suggesting precise, multi-line code changes in milliseconds. Unlike basic line completion, Next-Edit Autocomplete predicts larger logical blocks, such as instantly generating a unit test that corresponds exactly to a recent function behavior change. This integration eliminates the common trade-off between using a feature-rich IDE and having high-speed, intelligent autocomplete.

✂️ Efficient Inline Editing

Streamline minor refactoring and quick fixes using Inline Editing. Simply select a block of code within your editor, describe the modification you need (e.g., "Refactor this loop to use a list comprehension"), and Sweep will generate and apply the edits directly to the selected area. This capability drastically reduces the friction involved in making targeted, context-specific code improvements.

Use Cases

Sweep is designed to handle common development bottlenecks, allowing you to stay focused on high-value tasks.

Multi-File Feature Refactoring

You need to update an API endpoint that requires changes across the controller, service layer, and corresponding data models. Instead of manually navigating and editing six separate files, you instruct the Sweep Agent to perform the refactor. The Agent analyzes the necessary dependencies, applies the changes consistently across all files, and automatically runs the relevant unit tests to verify correctness before presenting the final output.

Instant Test Coverage Generation

You have just finished implementing a new utility function. Instead of manually mapping out test cases, you utilize Next-Edit Autocomplete. Since the model understands the function's recent changes and intent, it instantly generates a comprehensive unit test suite covering the new logic, ensuring immediate coverage validation.

Rapid Code Simplification

Reviewing a colleague's pull request, you notice a verbose section of legacy code that could be simplified. You highlight the 20-line block and use Inline Editing, prompting, "Simplify this logic using modern language features." Sweep quickly returns a concise, optimized 5-line version, saving time on minor but necessary code cleanup.

Unique Advantages

Sweep is built specifically to address the performance and integration gaps often found in general-purpose AI coding tools, offering developers verifiable benefits rooted in deep JetBrains integration.

• Deep IDE Integration for Superior Intelligence: The Sweep Agent leverages internal JetBrains static analysis tools. This is a critical differentiator that allows the Agent to understand the code structure and potential errors more intelligently and accurately than competing agents that rely solely on external analysis.

• Unmatched Speed and Productivity: Testimonials confirm the Next-Edit Autocomplete model is "incredibly fast" and "feels instantaneous." This speed is crucial for maintaining flow, as delays in suggestion generation are a primary killer of developer focus.

• Seamless Compatibility: Sweep supports the entire ecosystem, including IntelliJ IDEA, PyCharm, GoLand, Rider, WebStorm, and more, ensuring you don't have to sacrifice your preferred development environment for powerful AI assistance.

• Resolving the IDE Conflict: Sweep is explicitly designed to provide world-class autocomplete functionality within the JetBrains environment, eliminating the need for developers to switch to alternative IDEs just to access high-quality AI features.

Conclusion

Sweep delivers a powerful, integrated AI experience that respects the complexity and depth of the JetBrains development environment. By focusing on speed, seamless integration, and deep codebase understanding, Sweep allows professional developers to significantly increase their output and focus on solving higher-level problems.
