JetBrains AI Assistant vs Sweep AI (2026)

JetBrains AI Assistant

by JetBrains

Sweep AI

by Sweep

Pros

• ✓Built into eleven JetBrains IDEs plus Android Studio and ReSharper, with code completion from JetBrains' own Mellum model that does not use AI Credits, and a public preview extension for Visual Studio Code.
• ✓Several coding agents in one chat: JetBrains' own Junie, plus Claude Agent, Codex and GitHub Copilot, and any ACP-compatible agent from the registry, with MCP support in both directions.
• ✓Cloud models from OpenAI, Anthropic, Google and xAI through JetBrains AI, bring-your-own-key for OpenAI and Anthropic, and local models through Ollama or LM Studio.

Limitations

• –AI Free is not available in IntelliJ IDEA without an Ultimate subscription, PyCharm without a Pro subscription, or Android Studio, and it does not include next edit suggestions.
• –Cloud AI features pause when the included credits run out until the quota renews after 30 days or credits are topped up, and unused included credits do not roll over.
• –SSO and SCIM, AI audit logs, organization-wide provider keys and on-premises deployment require AI Enterprise at $60 per user per month billed annually, sold through a demo request.

Pros

• ✓A custom Tab autocomplete model built for the JetBrains code intelligence layer, with unlimited autocomplete on every paid plan.
• ✓Remote MCP servers with OAuth 2.0 and 2.1, web search and fetch tools, and AI code review for branch diffs.
• ✓SOC 2 compliance with zero data retention by default, and Privacy Mode keeps code out of model training.

Limitations

• –The VS Code and Zed extensions are newer than the JetBrains plugin, which Sweep built first.
• –Chat, code generation and advanced completions draw on monthly API credits, so heavy users may need automatic top-ups.
• –The Free Trial is limited to 1,000 autocompletes and $5 in API credits.
