JetBrains AI provider

JetBrains AI is a local-only provider. We read quota information directly from the IDE's configuration files.

Data sources + fallback order

1. IDE auto-detection

   • macOS: ~/Library/Application Support/JetBrains/
   • macOS (Android Studio): ~/Library/Application Support/Google/
   • Linux: ~/.config/JetBrains/
   • Linux (Android Studio): ~/.config/Google/
   • Supported IDEs: IntelliJ IDEA, PyCharm, WebStorm, GoLand, CLion, DataGrip, RubyMine, Rider, PhpStorm, RustRover, Android Studio, Fleet, Aqua, DataSpell
   • Selection: most recently modified AIAssistantQuotaManager2.xml

2. Quota file parsing

   • Path: <IDE_BASE>/options/AIAssistantQuotaManager2.xml (macOS/Linux)
   • Format: XML with HTML-encoded JSON attributes

XML structure

• quotaInfo attribute (JSON):
  • type: quota type (e.g., "Available")
  • current: tokens used
  • maximum: total tokens
  • tariffQuota.available: remaining tokens
  • until: subscription end date
• nextRefill attribute (JSON):
  • type: refill type (e.g., "Known")
  • next: next refill date (ISO-8601)
  • tariff.amount: refill amount
  • tariff.duration: refill period (e.g., "PT720H")

Parsing and mapping

• Usage calculation: tariffQuota.available / maximum * 100 for remaining percent
• Reset date: from nextRefill.next, not quotaInfo.until
• HTML entity decoding: 
 → newline, " → quote

UI mapping

• Provider metadata:
  • Display: JetBrains AI
  • Label: Current (primary only)
• Identity: detected IDE name + version (e.g., "IntelliJ IDEA 2025.3")
• Status badge: none (no status page integration)

Settings

• IDE Picker: auto-detected IDEs list, or "Auto-detect" (default)
• Custom Path: manual base path override (for advanced users)

Constraints

• Requires JetBrains IDE with AI Assistant enabled
• XML file only exists after AI Assistant usage
• Internal file format; may change between IDE versions
