In practice
You live in a JetBrains IDE and want an agent native to it. JetBrains AI centers on Junie, its coding agent, built into the tools your team already uses.
Coding agents that just generate code skip the part where it has to actually work. Junie runs a plan-execute-verify loop, so it checks its own work rather than dumping a draft.
You want to use your own model keys and connect your own tools. JetBrains AI's CLI supports BYOK, MCP, and skills, so you control the model and the integrations.

Recent platform changes
JetBrains updated its AI Assistant to natively integrate Claude Agent, powered by Anthropic's Agent SDK, directly into the IDE chat. The release also adds new spend management features, enabling users to track quota consumption and top up AI credits from within the interface.
Bears on: Integrations
View sourceJetBrains expanded its AI ecosystem by adding support for Junie, the JetBrains AI coding agent, to ReSharper 2026.2. This integration utilizes the Agent Client Protocol (ACP) to bring agentic coding capabilities directly into the ReSharper environment.
Bears on: Integrations
View sourceJetBrains Air, the agentic development environment, received an update adding support for multiple ACP (Agent Client Protocol) agents, including GitHub Copilot, OpenCode, Pi, and Cline. The release also introduces Java and Kotlin IDE intelligence and the ability to run Windows tasks in Docker.

From $10/mo
hybrid
Included quota
AI Pro (entry paid, $10/mo): ~10 AI credits/30 days, the Junie agent, Claude Agent, multi-model switching, and context-aware chat on top of unlimited local completion. AI Free is ~3 credits/30 days.
What is public
JetBrains AI (AI Assistant + the Junie agent) is a subscription on top of a JetBrains IDE license, with tiers: AI Free ($0), AI Pro $10/mo personal / ~$20 business (~$100/yr), AI Ultimate $30/mo personal (~$20/mo annual, $300/yr) / ~$60 business, and AI Enterprise (custom). AI Pro is included free with the All Products Pack / dotUltimate.
Billing mechanics
Flat tier bundling a monthly AI-Credit quota (1 credit = $1 USD); cloud chat, Junie, and Claude Agent consume credits, while local code completion is unlimited/free. Quota scales with price (Pro ~10 credits, Ultimate ~35 + a small bonus). Agent mode and pricier models (Claude Sonnet vs Gemini Flash) burn credits much faster. Run out, buy top-up credits (valid 12 months).
Cost watchouts
Separate from (on top of) the IDE license, opaque credit consumption (no pre-task estimate), agent mode + premium models burning credits in days, top-up costs, no BYO-key in the IDE plugin (only the Junie CLI)
Variable cost rationale
Flat tier plus $1 credits with fast, opaque burn on agent/premium-model use makes real spend hard to predict for heavy users
Additional watchouts
It's an add-on cost on top of the IDE; the credit model is opaque and burns fast on agentic work — a frequent user complaint
Overage / add-ons
When the monthly credit quota is exhausted, buy top-up AI credits ($1 each, valid 12 months) or upgrade tiers; local completion keeps working credit-free.

Commercial notes
AI Pro bundled free with the All Products Pack / dotUltimate; Ultimate includes ~$35/mo in credits + a $5 bonus with 12-month rollover; the Junie CLI supports BYO key (Anthropic/OpenAI/Google/xAI/OpenRouter); models include GPT-5, Claude 4.5 Sonnet, Gemini 3 Flash / 2.5 Pro
Key ambiguities
JetBrains doesn't clearly state what one credit buys in real-world tasks; quota burn is unpredictable and drew significant user backlash after a 2025 credit-system change
Cancellation / refund
Monthly or annual (annual saves ~17%); cancel anytime; top-up credits valid 12 months
Support SLA / resale
Ultimate adds priority model access and a larger quota; Enterprise adds private deployment and controls, and is sold only via JetBrains IDE Services
Missing data
Exact per-task credit costs and per-tier credit counts aren't transparently documented; business/commercial rates vary by source
