What is Sweep AI?
Overview
Sweep is the leading AI coding assistant purpose-built for JetBrains IDEs. While most AI tools (Cursor, Windsurf, Antigravity) are VS Code forks or new editors, Sweep is a plugin that lives natively inside IntelliJ IDEA, PyCharm, GoLand, WebStorm, PhpStorm, Rider, Android Studio, and the rest of the JetBrains family. It is the highest-rated AI plugin on the JetBrains Marketplace with a 4.9-star average across 40,000+ installations and adoption at companies including Ramp, Amplitude, Atlassian, and Klook.
Sweep originally launched in 2023 as an AI-junior-developer that handled GitHub issues and opened pull requests autonomously. Over 2025, the team refocused on the in-IDE experience for JetBrains, which is now the product's core.
Core Features
Sweep's centerpiece is its custom Tab model, branded as Tab, Tab, Tab. Unlike off-the-shelf completions, Sweep trained its own model specifically for IDE autocomplete latency and accuracy, and the result is suggestions that feel snappier than equivalent tools. The Tab model runs in milliseconds and respects your project's conventions through Sweep's codebase indexing.
The AI Agent goes beyond completions. You can describe a task, and the agent plans and executes across multiple files - writing code, running tests, and iterating until done. Like the JetBrains plugin ecosystem itself, the agent integrates tightly with Run Configurations, the debugger, and JetBrains' refactoring tools.
AI Code Review automates the first pass on pull requests, flagging issues, suggesting changes, and writing review comments before a human looks at the PR. This is a popular feature among teams that want to free up senior engineering time.
Sweep's web tools (Search and Fetch) let the agent pull live information from the web inside the IDE, useful for looking up API documentation or recent library changes. Recent additions include support for remote MCP servers with OAuth, which extends the agent into external tools securely.
The company emphasizes privacy: custom LLMs built specifically for JetBrains, no third-party code retention, SOC 2 compliance, and a Privacy Mode that ensures code is never used for training.
Pricing Analysis
Sweep offers a free trial with 1,000 autocompletes and $5 in API credits, so you can evaluate the product without committing. The Basic plan at $10 per month unlocks unlimited autocomplete - one of the cheapest unlimited-completion offerings on the market. Pro at $20 per month adds more API credits for chat and code generation, and Ultra at $60 per month is for power users who lean heavily on agent and review features.
For most JetBrains-heavy developers, the Basic plan at $10 per month is the sweet spot - unlimited autocomplete for less than half the cost of Cursor Pro.
Who Should Use Sweep
Sweep is the obvious choice for any developer who lives in JetBrains IDEs. It is particularly strong for Java, Kotlin, Python, and Go teams where JetBrains has long been the dominant editor. Enterprise teams looking for a SOC 2-compliant alternative to Copilot or Cursor that respects their existing IDE investment will find Sweep a strong fit.
It is not the right tool for developers who have already switched to VS Code or Cursor - the plugin only supports JetBrains.
