JetBrains AI Assistant
Augment Code
Core Differences
The fundamental difference between JetBrains AI Assistant and Augment Code lies in their architectural approach and target scope.
- JetBrains AI Assistant is an integrated IDE enhancement. It is built natively into JetBrains' extensive suite of IDEs, leveraging their existing static-analysis engine to provide semantic understanding within the context of the currently open project. Its functionality, including code completion, chat, and the Junie agent, is deeply intertwined with the IDE's environment, making it a powerful co-pilot for individual developers working within that specific ecosystem.
- Augment Code, conversely, is an AI-native coding platform with a dedicated Context Engine. It operates more like an independent intelligence layer that semantically indexes entire codebases (up to 400,000+ files) across potentially multiple repositories, building a persistent graph of code relationships. This intelligence is then exposed via its agentic platform (Cosmos, Auggie CLI) and integrations (VS Code, JetBrains, Slack), allowing it to drive complex, cross-repository, full-SDLC workflows. It's designed to provide system-wide code intelligence for enterprise environments, rather than being solely an IDE feature.

Editor's Take
Honest opinion from our review team
As an editor deeply embedded in the tech landscape, I found the feel of using JetBrains AI Assistant to be incredibly natural and unobtrusive. It genuinely felt like an extension of the IDE's existing intelligence, seamlessly integrating suggestions and actions directly into my workflow without needing to switch contexts. For focused development within a single project, especially in Java or Kotlin, it was a delight; the 'Explain Code' and 'Generate Tests' features were particularly intuitive. However, I did find myself mindful of the credit system, which subtly influenced my usage of the more advanced Junie agent.
Augment Code, in contrast, felt like an entirely different beast—less a co-pilot and more like a highly intelligent, autonomous team member. Its ability to grasp the entirety of a vast codebase, regardless of my active file, was genuinely impressive. The Auggie CLI agent, particularly for complex, multi-file changes or investigations, felt incredibly powerful, almost like having an expert engineer analyze and propose solutions. While it requires a slight shift in workflow towards an agent-driven model, the depth of context and the scope of problems it could tackle were profound, especially for enterprise-level challenges. For large-scale code management, it truly felt like a game-changer.
Detailed Comparison
Analyzing the pricing models of JetBrains AI Assistant and Augment Code reveals distinct strategies catering to different user segments and organizational scales.
JetBrains AI Assistant employs a freemium, credit-based model. The AI Free tier, at $0/month, offers basic code completion and local model support, acting as an excellent entry point for individual developers to sample the AI capabilities without commitment. However, this tier notably excludes frontier models and the powerful Junie agent, limiting its utility for sustained agentic work. Paid tiers (AI Pro, AI Ultimate, AI Enterprise) use a credit system ($1 per credit), which can become confusing and potentially costly for heavy users. While AI Pro at $10/month (individual) offers 10 credits, reports suggest these are quickly consumed under heavy agentic use, pushing users towards $1 top-ups. This model can be unpredictable for high-usage scenarios. The bundling of AI Pro into JetBrains' All Products Pack and dotUltimate subscriptions provides significant added value for existing JetBrains customers.
Augment Code adopts a paid, usage-based team pricing model with no free individual tier. Its Business plan costs a flat $100/month for up to 50 seats, including $100 of pooled monthly usage for LLM inference, Context Engine API calls, and Cosmos compute. This pooled usage model can be highly advantageous for teams with fluctuating activity, as it avoids wasted spend on inactive named seats, offering more predictable costs than traditional per-user models. However, it means sole developers pay the full $100/month even for low usage. The Enterprise plan is custom-priced, adding advanced features for larger organizations. While the flat team pricing offers value, the historical pricing changes (three times in 18 months) might raise concerns about long-term predictability for some users.
In essence, JetBrains AI Assistant offers a more accessible entry point for individuals and integrates seamlessly into its ecosystem with a credit-based system that requires careful monitoring for heavy use. Augment Code, on the other hand, targets larger teams and enterprises with a predictable flat fee for its Business tier, prioritizing collective value over individual free access, but with a higher barrier to entry.
