Capabilities
Core Features
LLM-Powered Personas
AI characters that simulate realistic customers with domain-specific knowledge, configurable difficulty tiers, and persona archetypes — explosive, passive-aggressive, demanding, confused, impatient.
Multi-Provider Voice Pipeline
Deepgram STT, ElevenLabs TTS, and OpenAI Realtime API for natural voice conversations. WebSocket streaming with Voice Activity Detection and automatic provider failover.
3D Avatar with Lip Sync
Animated conversation partner with lip synchronization (TalkingHead.js + Three.js). Emotion mapping visualizes avatar states: calm, angry, happy, confused, and more.
AI-Powered Evaluation
Automatic multi-dimensional analysis of conversation performance. Calibrated rubrics, golden samples for consistent scoring, regression tests, and review queues.
Skill Radar Charts
Visual skill development tracking with benchmark comparison. Multi-dimensional scoring across empathy, expertise, solution orientation, and more.
Adaptive Training Paths
Structured learning journeys with progressive complexity (Draft → Published → Archived). Tag-based scenario selection with difficulty adjustment.
Gamification Engine
XP system (50 XP base × difficulty multiplier), 100 levels with progressive curve, badges (milestone, streak, skill, special), leaderboards, and daily login streaks.
PDF Certificates
Auto-generated completion certificates (WeasyPrint) with public verification URLs. Certificate management with revoke functionality.
Knowledge Base
Structured articles with knowledge levels and execution styles. Articles are automatically injected into AI persona context during conversations.
AI Scenario Generator
Automatic creation of new scenarios and variations via GenAI. Template-based variations for training variety.
PII Detection & Redaction
Automatic detection and removal of personal data (email, phone, IBAN, credit card, ID, SSN, addresses) from conversations.
Prompt Injection Defense
Multi-category detection (instruction override, role escape, jailbreak, encoding attacks) with threat-level assessment (NONE to CRITICAL).
Platform
Two Platforms. One Experience.
Web and native iOS — both fully featured, always in sync.
Web Application (Vue 3 SPA)
40 views (12 trainee + 28 admin), 50+ routes with auth guards, 24 Pinia stores, full i18n (DE/EN), Chart.js radar charts, and a comprehensive SCSS design system.
iOS App (Swift/SwiftUI)
Native iOS 17.0+ with Swift 6.0 strict concurrency. MVVM architecture, Keychain JWT storage, 33 Swift files, 5-tab navigation, and full gamification integration.

Where Bragi fits in this landscape
Second Nature AI is cloud-only and expensive with no self-hosting. Rehearsal VRP offers video roleplay but no voice or 3D avatar. Cogito provides real-time coaching but no scenario training or gamification. Bragi combines voice + 3D avatar simulation, calibrated AI evaluation with golden samples, multi-provider LLM routing, gamification, adaptive training paths, and a native iOS app — all self-hosted.
Transparent Pricing
