What Sweep Does
Sweep is now a JetBrains-first AI coding assistant built around two pillars: a next-edit autocomplete that predicts where you'll edit next, and an inline coding agent that handles multi-file changes within the IDE. The original GitHub bot — which converted issues into pull requests autonomously — has been deprecated in favor of a much tighter editor integration. In February 2026, the team also open-weighted a 1.5B model purpose-built for next-edit autocomplete, signaling a deeper investment in fast, locally-runnable assistance over the cloud-only agent it started as.
Next-Edit Autocomplete
Next-edit autocomplete is Sweep's defining feature and the reason most developers install it. Instead of suggesting completions only at the cursor, it watches your recent edits and predicts where you'll likely edit next — a renamed variable elsewhere, a matching parameter in a sibling function, or a test that needs to track the production change. Pressing tab jumps you to the proposed location and accepts the suggested edit in one motion, which compresses the typical multi-file refactor loop dramatically.
The 1.5B model released as open weights in February 2026 is small enough to run locally while outperforming larger models on next-edit benchmarks. The JetBrains plugin currently reports a 4.9-star rating with more than 40,000 installs, which is a meaningful proof point in a category dominated by Copilot, Cursor, and Continue. For developers who live in IntelliJ, PyCharm, WebStorm, or GoLand, this is the autocomplete that finally adapts to JetBrains-shaped workflows.
Agent and Inline Editing in JetBrains
The agent and inline editing capabilities are the second half of the value proposition, and they are currently JetBrains-exclusive. Sweep's agent can take a natural-language task, plan a set of multi-file edits, and stage them as a reviewable diff inside the IDE — closer to Cursor's Composer or Cody's Agentic Chat than to a GitHub bot. Because everything happens locally with the JetBrains project model, it can use language servers, indexed dependencies, and run configurations as context.
Inline editing brings the same agent to a single hunk: highlight a block, describe the change, and Sweep produces an edit that respects the surrounding code style. Combined with next-edit autocomplete, the two flows compress the path from idea to working code without forcing a context switch to a chat sidebar. The JetBrains plugin is where Sweep's roadmap visibly leads — VS Code and Zed remain on the autocomplete-only tier as of late 2025.
Cross-IDE Support and Open Source
VS Code and Zed users get next-edit autocomplete but not the agent or inline editing features. That positioning is deliberate: Sweep is leaning into the JetBrains ecosystem rather than spreading thin across every editor. The open-weight 1.5B model also lowers the barrier for self-hosted experimentation, and the company maintains an active GitHub presence under github.com/sweepai with research and tooling repositories.
The trade-off is that teams standardized on VS Code see only a fraction of the product. For those teams, Continue, Cursor, and Copilot remain stronger choices. But for JetBrains-heavy organizations — which is most of the JVM and Python enterprise world — Sweep is one of the few assistants that treats JetBrains as the primary target rather than a secondary port of a VS Code-first product.
Pricing and Use Case Fit
Pricing is simple and credit-based. A free tier ships with 1,000 autocompletes and $5 of API credits to try the agent features. Paid plans run $10 per month for Basic, $20 for Pro, and $60 for Ultra, with all paid tiers receiving unlimited autocomplete and an API credit allocation equal to the plan cost. Unused credits roll over for 30 days, which softens the typical usage-based billing anxiety.
The fit is clearest for individual JetBrains developers and small teams that want next-edit autocomplete without committing to Cursor's IDE switch or Copilot's broader subscription. Larger organizations that need policy controls, SSO, and centralized billing will find the offering still maturing. But the pricing is positioned aggressively for the productivity tier — $10–20 for unlimited autocomplete is competitive with everything else in the JetBrains plugin market.
The Bottom Line
Sweep's pivot from a GitHub-issue bot to a JetBrains-first coding assistant is one of the cleaner repositionings in the AI dev tools space. Next-edit autocomplete is a genuinely differentiated feature, the open-weight 1.5B model signals a real research bet, and the JetBrains agent fills a gap that VS Code-centric tools have left underserved. For developers who already live in JetBrains IDEs, Sweep is now one of the most interesting AI assistants worth a free-tier trial.
