Move your team from JetBrains AI to Cursor.
Each person gets a short interview, then a personalized step-by-step guide showing exactly where their saved work, prompts, and projects land in Cursor — and the few things that need a manual step, walked through. You send one invite; nobody becomes the help desk, and nothing in JetBrains AI is changed or cancelled. Want to see where you’re paying for both first? Run the free audit.
Both Cursor (Agent/Composer mode) and JetBrains Junie execute multi-step autonomous coding tasks — planning, editing multiple files, running tests, and self-correcting. Cursor's agent is built into the Agents Window (Cmd/Ctrl+I) and can run cloud agents on remote VMs with PR-based handoff; Junie is a separate plugin (install from JetBrains Marketplace) that operates in-IDE in Code mode (plan → apply → compile → self-correct) or Ask mode. To migrate from Cursor to JetBrains: install the Junie plugin, open the Junie tool window, and describe tasks the same way you would in Cursor's Agent pane — Junie generates a blueprint before executing, giving a review checkpoint analogous to Cursor's Plan mode. MCP servers carry over: both tools support MCP; reconfigure your MCP server JSON in AI Assistant settings. To migrate the reverse: enable Cursor Agent mode, paste the task description, and choose a model — no separate plugin install is needed.
- Warning: Junie requires a paid JetBrains AI Pro or Ultimate subscription; there is no free tier for agentic tasks. Cursor Cloud Agents also require a paid plan, but Cursor's in-IDE Agent mode is available on Pro ($20/mo).
- Warning: Cursor supports parallel multi-agent execution (up to 8 simultaneous agents via git worktrees); Junie runs a single agent per task with no equivalent parallel execution capability.
- Warning: Cursor Bugbot performs automated PR code review with usage-based pricing (~$1–$1.50 per run); JetBrains AI Self-Review is a lighter in-IDE diff analysis, not a full PR-review bot — there is no direct Junie equivalent to Bugbot.
- Warning: Junie BYOK / custom-model support is documented for Junie CLI only, not the IDE plugin; Cursor Agent uses the model you select in the model picker, including BYOK keys.
Both tools offer a persistent AI chat panel directly inside the editor. In Cursor the panel is the Agents Window (Cmd/Ctrl+L to open, or Cmd/Ctrl+I for agent/composer mode), with Ask, Plan, and Agent sub-modes and context supplied via @-mentions (@file, @folder, @Docs, etc.). In JetBrains AI the panel is the AI Assistant chat sidebar, launched via the toolbar or the dedicated shortcut; Codebase Mode gathers relevant project context automatically without manual @-mentions, and slash commands (/explain, /refactor, /web, /docs) cover common actions. To migrate from Cursor to JetBrains: open the AI Assistant tool window, enable Codebase Mode for ambient context retrieval (equivalent to Cursor's repo indexing), and replace @-file mentions with file attachments or dragging files into the chat. Custom rules from .cursor/rules/*.mdc should be adapted into the AI Assistant Prompt Library or a project-level Markdown rules file. Migrating the reverse: set up @-mentions and Cursor Rules files; Codebase Mode context is replicated by letting Cursor auto-index the workspace and relying on its agentic file search.
- Warning: Cursor's Agents Window unifies chat, agent runs, PR review tabs, browser, and terminal in one surface; JetBrains AI Assistant chat and the Junie agent are separate plugins with separate tool windows — you must open both to get equivalent coverage.
- Warning: JetBrains AI Free tier allows only 3 AI Credits per 30 days, making chat-heavy workflows expensive to test without a paid plan; Cursor's Hobby tier provides more generous chat usage before hitting limits.
- Warning: Chat history in JetBrains persists per-project; in Cursor it is accessible via @Past Chats but search is limited — migrating conversation history between tools is not supported natively.
Both products provide always-on ghost-text inline completion that accepts with Tab. Cursor Tab is powered by Anysphere's proprietary model and predicts multi-line and cross-file ripple edits; JetBrains inline completion is powered by Mellum (JetBrains' own code-optimised LLM) and covers 24+ languages. To migrate from Cursor to JetBrains: install JetBrains AI Assistant plugin in your IDE (IntelliJ, PyCharm, WebStorm, etc.), enable inline completion in Settings > Editor > General > Code Completion > Inline, and sign in to JetBrains AI — completion activates automatically. No configuration export exists; IDE-specific language settings (excluded files, trigger delays) must be reconfigured manually. To migrate the reverse: install Cursor, sign in, and Tab completion is on by default with no setup beyond workspace opening. Language-specific ignores should be re-expressed via .cursorignore.
- Warning: Cursor Tab is unavailable on the Free Hobby tier beyond a limited monthly quota; JetBrains inline completion (Mellum) is free and unlimited on all plans including AI Free — completion parity is easier to maintain in JetBrains without a paid subscription.
- Warning: JetBrains code completion does not work with BYOK or local/offline models (Ollama, LM Studio) — the Mellum model is proprietary and cloud-hosted. Cursor BYOK also does not replace the Tab model. Neither product lets you substitute a custom completion model.
- Warning: Cursor Tab predicts cross-file ripple edits beyond the current cursor position; JetBrains' equivalent is Next Edit Suggestions (gated to AI Pro and above), which is a separately enabled feature — vanilla completion in JetBrains does not predict cross-file edits.
Both products allow users to bring their own API keys (BYOK) or use locally-hosted models instead of the vendor's default. In Cursor, BYOK is configured in Settings > Models > API Keys (supports OpenAI, Anthropic, Google, Azure OpenAI, AWS Bedrock); model selection is per-conversation via the model picker. In JetBrains AI, BYOK and local models are configured via Settings > Tools > AI Assistant > Providers & API keys; Ollama and LM Studio are supported for fully offline operation. To migrate from Cursor to JetBrains with BYOK: copy your API key for the provider (Anthropic, OpenAI, Google, etc.) and paste it into the JetBrains AI Providers settings page; select the model in the chat model picker. For local models, install Ollama, pull a model, and point JetBrains at the Ollama endpoint. To migrate the reverse: copy keys into Cursor Settings > Models; Ollama is not natively supported in Cursor BYOK — you would need an OpenAI-compatible proxy (e.g. LiteLLM) to expose local models to Cursor.
- Warning: Neither product allows BYOK or custom models for inline code completion — both rely on proprietary models (Cursor Tab / JetBrains Mellum) that cannot be replaced. Teams hoping to route all inference through their own keys will still have completion traffic going to vendor infrastructure.
- Warning: JetBrains AI local/offline models disable MCP tool invocation; Cursor BYOK keys work for chat but the Tab model is also proprietary and unaffected by key configuration.
- Warning: JetBrains Junie autonomous agent BYOK is only available via Junie CLI (not the in-IDE plugin); Cursor's agent respects the selected BYOK model in the model picker.
Cursor and JetBrains AI both predict and propose code edits beyond simple completion, presenting them as reviewable diffs. Cursor's Agent/Composer produces multi-file diffs reviewed in the Agents Window 'Changes' tab with per-hunk accept/reject; Cmd/Ctrl+K edits a selection inline. JetBrains Next Edit Suggestions predicts the next location in the file you are likely to edit and proposes the change inline (large edits appear in a dedicated diff view; small ones as inline popups). To migrate from Cursor to JetBrains: enable Next Edit Suggestions in Settings > Editor > General > Code Completion > Inline (requires AI Pro or above), then work normally — suggestions appear automatically as you edit. For Junie-level multi-file edits, use the Junie plugin in Code mode rather than Next Edit Suggestions alone. To migrate the reverse: use Cursor's Composer/Agent (Cmd/Ctrl+I) for multi-file change generation; for inline single-hunk edits, use Cmd/Ctrl+K on a selection.
- Warning: JetBrains Next Edit Suggestions is gated to AI Pro and AI Ultimate; AI Free users get no equivalent beyond standard completion. Cursor's Composer/Agent multi-file editing is on the Pro ($20/mo) tier.
- Warning: Cursor's Agent produces changes as a single reviewable batch with full rollback checkpoints; Next Edit Suggestions proposes one edit location at a time — there is no equivalent bulk diff review surface in JetBrains AI without Junie.
- Warning: Next Edit Suggestions are unavailable when using local or third-party BYOK models; Cursor file editing works with any selected model including BYOK keys.
Cursor embeds an AI-assisted terminal inside the IDE (Cmd/Ctrl+K in the integrated terminal for natural-language command generation) and the Agent can execute shell commands autonomously under configurable run modes. JetBrains Junie CLI is a standalone terminal agent that operates outside any IDE and is LLM-agnostic. To migrate from Cursor's terminal AI to JetBrains: install Junie CLI (separate from the IDE plugin), configure a model provider (JetBrains AI subscription, BYOK Anthropic/OpenAI/Google/xAI, or the free Gemini trial), then run tasks from any terminal or CI pipeline — Junie CLI offers one-click migration from competing agents. To migrate the reverse: open Cursor's integrated terminal, use Cmd/Ctrl+K for one-off command generation, or switch the Agent run mode to 'Run Everything' for fully automated shell execution as part of a broader agent task.
- Warning: Junie CLI is in public beta (as of March 2026) and may lack stability guarantees; Cursor's integrated terminal AI (Cmd/Ctrl+K) is GA but the terminal prompt is no longer prominently documented in Cursor's June 2026 docs.
- Warning: Cursor terminal AI is IDE-embedded only — it cannot run headlessly in CI without a Cloud Agent; Junie CLI is purpose-built for CI/CD and headless environments, giving JetBrains a structural advantage for pipeline automation.
- Warning: Cursor's Agent run-mode safety controls (Auto-Review, Allowlist, Sandbox) apply to in-IDE terminal calls only; Junie CLI has no equivalent graduated-trust sandbox layer documented for the terminal.
