Sweep

Sweep, a Y Combinator-backed company, is a coding assistant plugin for JetBrains IDEs (IntelliJ IDEA, PyCharm, Android Studio, WebStorm, PhpStorm, Rider) built around a custom autocomplete model and a separate AI agent for more complex coding tasks. The custom autocomplete model delivers suggestions in milliseconds, the AI agent (built on proprietary models) handles larger coding tasks with codebase indexing for context-aware recommendations, and it includes code review capabilities plus web search/fetch tools for pulling in outside information. SOC 2 compliance with zero data retention supports use with sensitive codebases. 40,000+ installations and a 4.9-star JetBrains Marketplace rating, with testimonials from developers at Ramp, Amplitude, and Atlassian, point to genuine adoption; the plugin is free to download, with pricing details on a separate page. Good fit for a JetBrains IDE user (rather than VS Code) who wants a dedicated coding assistant built specifically for that ecosystem rather than a VS-Code-first tool retrofitted for JetBrains.
