Problem

JetBrains developers have historically had to choose between the IDE they prefer and modern AI coding assistance: Sweep says existing assistants provide materially weaker support in JetBrains, while users report that “the AI sucks” even though they value the IDE’s features. The pain is both workflow friction and lost productivity—developers must switch editors or tolerate poor autocomplete when writing production code. Sweep’s founders say their own use of its autocomplete hundreds of times per day doubled their productivity, making fast, context-aware completion the killer use case.

Product / Service

Sweep is an AI coding assistant delivered primarily as a plugin for JetBrains IDEs, with support for IntelliJ IDEA, PyCharm, Android Studio, WebStorm, PhpStorm, Rider, and other editors. It combines an agent for chat and code changes with next-edit autocomplete, inline editing, AI commit messages, and code review. The agent can use the current file and broader codebase as context, while its autocomplete uses a custom model and the IDE’s code index to suggest precise changes quickly; developers invoke the agent from the IDE and accept completions with Tab.

The service is free to try and monetizes through individual and team subscriptions. The free trial includes 1,000 autocompletes and $5 of API credits; paid plans begin at $10 per month, provide unlimited autocomplete, and add API credits for agent usage. Sweep emphasizes its own models, zero data retention, privacy mode, SOC 2 compliance, and self-hosted or on-premise deployment for teams that cannot send source code to third parties.

Market

Sweep competes in the AI coding assistant and developer-tools market, positioning itself as a JetBrains-focused alternative to Cursor, Windsurf, GitHub Copilot, JetBrains AI Assistant, Augment Code, and other IDE plugins. Its differentiation is not merely code generation but bringing fast autocomplete and agent workflows into the existing JetBrains environment, avoiding the switching cost of moving to an AI-first editor while offering privacy-oriented deployment for enterprise users.

The product is active and has meaningful early adoption, although the evidence gathered does not disclose revenue or establish profitability. Sweep’s site claims a 4.9-star rating, more than 40,000 installs, and use by thousands of professional developers; the JetBrains Marketplace page reports 68,022 downloads and a 4.7 rating across 76 ratings. Y Combinator lists Sweep as founded in 2023 and active, with a four-person team, while the company’s $10, $20, and $60 monthly plans demonstrate a live commercial model rather than a purely pre-launch product.
