Last updated: June 2026 · Written for developers currently using JetBrains IDEs
Stay on JetBrains AI Assistant if you write Java, Kotlin, PHP, Go, C#, or any language where JetBrains' deep IDE tooling — debugger, refactoring engine, database tools, run configurations — is a core part of your workflow. The switching cost is real, and Cursor does not replicate JetBrains' language-specific tooling.
Switch to Cursor if you write primarily JavaScript, TypeScript, or React/Next.js and already use VS Code. The AI capability gap is meaningful, and the switching cost from VS Code to Cursor is minimal — your extensions, themes, and keybindings transfer in one click.
Use both if you need JetBrains' language tooling and want the best AI assistance: keep JetBrains as your primary IDE and install GitHub Copilot or Continue.dev inside it for AI that exceeds JetBrains AI Assistant's current capability.

Cursor is an AI-native code editor built as a fork of VS Code by Anysphere. It replaces your editor entirely — not as an extension, but as the IDE itself. Its AI is built into every layer: tab completions that predict multi-line edits based on your codebase, Composer for autonomous multi-file agent tasks, and background agents that run on cloud VMs for asynchronous work.
Cursor's AI capability is generally ahead of JetBrains AI Assistant in autocomplete quality, multi-file agent depth, and model choice flexibility. The question is whether that AI advantage justifies leaving JetBrains' language tooling behind.
JetBrains AI Assistant is the AI feature set built into every JetBrains IDE — IntelliJ IDEA, PyCharm, WebStorm, GoLand, PhpStorm, Rider, CLion, DataSpell, and others. It is not a separate product or subscription — it comes with your existing JetBrains IDE license.
Key capabilities include inline completions, AI chat with codebase context, test generation, documentation generation, image-to-code generation, code review agents, and a Jira implementation agent that takes a ticket description and implements the described change.

This comparison is not really about which AI features are better — Cursor's AI is generally ahead. The real question is whether the AI capability improvement is worth the switching cost for your specific language and workflow.
JetBrains developers have typically invested years in their IDE setup:
Cursor replicates none of this. It is a VS Code fork with excellent AI, and VS Code's ecosystem is excellent for JavaScript and Python. But it is not a substitute for JetBrains' Java debugger, IntelliJ's Spring Boot tooling, or PhpStorm's PHP refactoring engine.
Verdict: Stay on JetBrains AI Assistant.
This is the clearest case. IntelliJ IDEA's Java and Kotlin tooling has no equivalent anywhere else. The debugger with step-through evaluation, the Spring Boot tooling with live bean graph visualization, the Maven/Gradle integration with conflict resolution, the null-safety analysis — none of this exists in VS Code or Cursor.
Java and Kotlin developers on IntelliJ should use JetBrains AI Assistant as their baseline. If AI Assistant's capability proves insufficient for specific tasks, add GitHub Copilot inside IntelliJ (the Copilot plugin is mature and feature-complete for JetBrains) or Continue.dev for BYOK flexibility. Switching to Cursor for Java development means giving up a decade of JetBrains' language investment.
Verdict: Stay on JetBrains AI Assistant.
Android Studio is based on IntelliJ IDEA and shares its plugin ecosystem. Even if you use Android Studio rather than IntelliJ, JetBrains AI Assistant's Kotlin support is deep and the tooling is native. Cursor has no Android development support.
Verdict: Stay on JetBrains AI Assistant.
PhpStorm has the strongest PHP tooling available — type inference, Composer integration, Symfony and Laravel framework support, PHP-specific inspections and refactoring. VS Code's PHP support is functional but significantly behind PhpStorm for professional PHP development.
If PhpStorm's AI Assistant reaches its limits for complex tasks, GitHub Copilot's PhpStorm plugin is the recommended addition — not switching to Cursor.
Verdict: Stay on JetBrains AI Assistant, consider Continue.dev.
GoLand provides Go-specific tooling — goroutine debugging, go test integration, Go module management, interface method generation — that VS Code's Go extension approximates but does not fully match at the same polish level.
JetBrains AI Assistant performs well for Go. If you want additional AI flexibility — particularly BYOK model choice or local model support — Continue.dev with its JetBrains plugin adds this capability inside GoLand without requiring you to switch IDEs. See Continue.dev Rules guide for Go-specific configuration.
Verdict: Context-dependent. PyCharm users should evaluate carefully.
This is the most nuanced case. Python is well-supported in both VS Code (Cursor) and PyCharm. The decision hinges on what you use PyCharm for:

Verdict: Cursor is likely worth it for WebStorm users.
This is the one case where switching to Cursor is more defensible. The React/Next.js/TypeScript ecosystem is VS Code-native — most tooling, documentation, and community practice assumes VS Code. WebStorm is excellent, but it is competing against an ecosystem that defaults to VS Code.
Cursor's AI is meaningfully ahead of JetBrains AI Assistant for TypeScript — its multi-line completions, component tree awareness, and App Router understanding are better. The switching cost from WebStorm to Cursor is lower than from IntelliJ to Cursor because VS Code's web development tooling is genuinely competitive with WebStorm.
For JavaScript/TypeScript developers on WebStorm who want better AI without switching: GitHub Copilot's WebStorm plugin is the pragmatic middle path. Full comparison: Cursor vs GitHub Copilot.

Verdict: Stay on JetBrains AI Assistant.
JetBrains Rider is the only IDE that provides IntelliJ-quality tooling for C# and .NET development outside of Visual Studio. Its refactoring engine, debugger, and .NET-specific inspections have no equivalent in VS Code or Cursor. The AI capability gap does not justify abandoning Rider's language tooling for .NET development.
This is the most misunderstood part of the comparison.
JetBrains AI Assistant costs:
If you already pay for a JetBrains IDE subscription, AI Assistant adds nothing to your monthly bill. For developers already paying $24.90–38.90/month for their JetBrains subscription, AI Assistant is effectively free.
Cursor costs:
Cursor Pro at $20/month is a separate subscription on top of whatever IDE costs you currently have. If you switch from JetBrains to Cursor, you eliminate the JetBrains subscription — but you are trading JetBrains' language tooling for Cursor's AI, which may be a bad trade for your stack.
The realistic scenarios:

Setting aside the switching cost question, here is how the AI features compare head-to-head.
JetBrains reports a 30% average autocomplete acceptance rate for AI Assistant — a strong result for IDE-based autocomplete. Cursor's tab completions are generally accepted at higher rates in developer surveys, particularly for TypeScript and Python, and provide longer multi-line suggestions.
For Java and Kotlin, JetBrains AI Assistant benefits from deep language model understanding specific to JVM patterns. Cursor's completions are less specialized for JVM development.
Winner by stack: Cursor for TS/JS/Python, JetBrains AI for Java/Kotlin.
Cursor's Composer and background agents are ahead of JetBrains AI's current agent capabilities. Cursor's background agents can run autonomously on cloud VMs, are triggerable via Slack or GitHub, and can run up to 8 in parallel.
JetBrains AI's agents are more task-specific: the code review agent evaluates PRs against organizational standards, the Jira implementation agent takes a ticket and implements the described change. These are genuinely useful but narrower than Cursor's open-ended agent mode.
Winner: Cursor — more capable and more flexible agent mode.
JetBrains AI has features with no Cursor equivalent:
Winner: JetBrains AI for these IDE-specific integrations.
Cursor lets you choose your AI model per session — Claude Sonnet 4.6, Claude Opus 4.6, GPT-4o, Gemini — and switch between them freely. JetBrains selects the model for you based on the task, with limited user control over which model handles a given interaction.
Winner: Cursor — explicit model choice gives developers more control.
For most JetBrains developers, the best answer to "should I switch to Cursor" is: add a second AI tool inside JetBrains instead of switching.
Two options work well:
GitHub Copilot inside JetBrains: The mature, feature-complete Copilot plugin adds better autocomplete, Copilot Chat, and Copilot Edits (multi-file agent) at $10/month. For most JetBrains developers, this is the pragmatic upgrade path. Configure it with GitHub Copilot Rules for project-specific behavior.
Continue.dev inside JetBrains: The open-source, free plugin adds BYOK model choice and local Ollama model support. You get Cursor-level model flexibility (Claude Sonnet 4.6, GPT-4o, any Ollama model) inside your existing JetBrains IDE at zero subscription cost. See Continue.dev Rules guide for JetBrains configuration.
Either option gives you significantly better AI than JetBrains AI Assistant alone — without the switching cost.
There are genuine scenarios where switching from JetBrains to Cursor is the right decision:
You write primarily TypeScript/JavaScript and currently use WebStorm. The VS Code ecosystem is the default for web development, and the switch from WebStorm to Cursor is lower-cost than from IntelliJ. Cursor's AI advantage for TypeScript is real.
Your JetBrains subscription is expiring and you are re-evaluating. If you are about to pay another year of JetBrains licensing for a stack (web development, Python) where VS Code tooling is comparable, switching to Cursor saves $4–19/month and gains better AI.
Your team is standardizing on VS Code-based tools. If your team has already moved to VS Code and you are the last JetBrains holdout, switching to Cursor aligns you with the team's shared configuration and reduces the rules/settings divergence.
You primarily write Python web applications and do not use PyCharm's scientific features. Python in VS Code/Cursor is competitive with PyCharm for web development. The AI advantage may justify switching.
| Developer type | Recommendation | Reason |
|---|---|---|
| Java / Spring developer | Stay — add GitHub Copilot or Continue.dev | IntelliJ tooling has no equivalent |
| Kotlin / Android developer | Stay on JetBrains AI | Android Studio tooling is irreplaceable |
| PHP / Symfony developer | Stay — add GitHub Copilot | PhpStorm PHP tooling is best-in-class |
| Go developer | Stay — consider Continue.dev | GoLand Go tooling is ahead of VS Code |
| Python / Django dev | Evaluate — Cursor is viable | VS Code Python competitive; AI advantage real |
| TypeScript / React dev | Consider switching | VS Code ecosystem is native for web; AI gap favors Cursor |
| .NET / C# developer | Stay on JetBrains AI | Rider is the only non-Microsoft option for .NET |
| Data scientist (DataSpell) | Stay | Jupyter integration and data tools superior in JetBrains |
| Freelancer on multiple stacks | Stay — add GitHub Copilot | Cross-IDE Copilot subscription covers all environments |
For AI capability in isolation — autocomplete quality, multi-file agent depth, model choice — Cursor is generally ahead. But JetBrains AI is better for developers who need JetBrains' language-specific tooling (Java, Kotlin, PHP, Go, C#), where the AI quality difference does not justify abandoning years of IDE investment.
Yes, but with significant limitations. Cursor has no JVM-specific tooling — no Spring Boot support, no Kotlin null-safety inference, no Gradle/Maven GUI, and no debugger comparable to IntelliJ's. Java and Kotlin developers who switch to Cursor accept meaningful workflow regressions in exchange for better AI autocomplete.
JetBrains AI Assistant has a free tier with limited usage. Full access requires a JetBrains IDE subscription ($24.90–38.90/month for individual licenses). For developers already paying for a JetBrains subscription, AI Assistant adds no additional cost.
For most developers, yes — GitHub Copilot's autocomplete acceptance rates are higher and its Copilot Edits (multi-file agent) is more capable than JetBrains AI's current agent features. The Copilot JetBrains plugin is mature. Adding Copilot at $10/month to your JetBrains subscription is often a better upgrade path than switching to Cursor. See Cursor vs GitHub Copilot for a detailed comparison of the two.
Yes. Continue.dev has a JetBrains plugin that works in IntelliJ, PyCharm, WebStorm, GoLand, and others. It adds BYOK model choice (Claude Sonnet 4.6, GPT-4o, Gemini, or any Ollama local model) inside your existing JetBrains IDE at zero subscription cost. For privacy-sensitive work or maximum model flexibility without switching IDEs, Continue.dev is the recommended addition.
Use both: IntelliJ IDEA for your primary IDE with GitHub Copilot or Continue.dev for AI assistance. You get JetBrains' world-class Java tooling and better AI than JetBrains AI Assistant — at the cost of an additional subscription (Copilot at $10/month) or no additional cost (Continue.dev free).
Cursor uses .cursor/rules/*.mdc files to inject project-specific coding conventions into every AI interaction. JetBrains AI Assistant does not have an equivalent per-project rules file — its context comes from the IDE's project understanding rather than developer-written instructions. For teams that want explicit control over AI behavior, Cursor's rules system is more flexible. See Cursor Rules guide.
