One app that takes an Indian defence aspirant across the whole journey — adaptive prep for the written exams, the full SSB suite with real AI evaluation, mock tests, fitness, mentorship and community. A working product, not slideware: the app scores real answers on-device with no backend and no API key required, with an optional live-Claude upgrade.
🎯 Built for the Vande Bharatam initiative. Prototype for testing & demonstration.

Quality defence coaching in India is expensive, offline, and concentrated in a few cities — while at the SSB only a small fraction of candidates are recommended. PRAHARI makes end-to-end prep affordable, adaptive and available on any phone, with human-verified AI as the differentiator.
- Real SSB evaluation — type WAT / SRT / TAT / Self-Description answers and get an actual Officer-Like-Quality index, per-quality breakdown and specific feedback. It genuinely discriminates (strong answers → ~90, weak/negative → ~44).
- AI mock interview — conversational, PIQ-based, dynamic follow-ups, scorecard.
- Mock tests — real MCQ bank, scored, with per-question review.
- Career Fit Finder — rule-based eligibility across all 10 defence entries.
- Adaptive exam hub — NDA, CDS, AFCAT, TGC, SSC Tech, TES, Navy, Coast Guard, CAPF, Agniveer, each with its own syllabus/subjects.
- Persistence & gamification — streak, XP, levels, and an OLQ trend chart from your real sessions
(stored on device via
localStorage). - 3 roles — Student, Mentor dashboard, Admin console.
- Optional real Claude AI — paste a key in ⚙️ Settings, or deploy the backend proxy.

Prototype for testing/demos. The on-device evaluator is an AI-assisted heuristic, not a validated psychometric model; question banks are small samples and financial/market figures are indicative. The real build adds ex-officer rubric validation and a proper content pipeline.
