Sweep is a US-based AI coding assistant purpose-built for JetBrains IDEs, including IntelliJ IDEA, PyCharm, Android Studio, WebStorm, GoLand, Rider, PhpStorm, CLion, RustRover, RubyMine and JetBrains Gateway. The product combines an agentic workflow, next-edit autocomplete and AI-driven code review in a single plugin, with a focus on speed, privacy and cost efficiency.
Founded in 2023, Sweep originally entered the market with broader AI-on-GitHub ambitions and has since narrowed sharply onto the JetBrains ecosystem, where it has built a strong position. The JetBrains Marketplace listing reports more than 40,000 installs and a 4.9-star rating, with active issue tracking visible in the public repository as of 2026, indicating continued maintenance and feature work. The team uses proprietary LLMs to optimise for response latency and privacy, and the product is SOC 2 compliant with zero data retention by third parties.
On funding, Sweep has raised approximately $5.5M in disclosed capital, with its most recently reported round listed as a pre-seed. The company has so far not announced a large later-stage round, suggesting a deliberate focus on capital efficiency relative to peers in the AI coding agent category.
While Sweep shares its name with broader AI coding conversations, it should not be confused with other AI coding companies that have been acquired or pivoted in 2025-2026. The current Sweep product is the JetBrains-native assistant operated by sweepai, available via sweep.dev and the JetBrains Marketplace.
NeuronFeed lists Sweep as one of the leading AI coding assistants for the JetBrains ecosystem, particularly for engineers who want a high-quality alternative to VS Code-centric tooling.
