Junior Ai: High-Level Project Specification
Before a line of code is written, this document captures everything a development partner needs to scope, estimate, and deliver Junior—an AI-powered social platform where users train “Junior” avatars that debate, compete, and grow.
1. Executive Summary
Junior turns social media into a game of minds. Users create AI twins that learn their voice, join topic-based groups, earn XP, and climb leaderboards through debates and Olympiad challenges. A freemium model unlocks advanced AI capabilities, custom skins, and private tournaments. Target launch is a polished MVP in ~6 months assuming 3 hrs/day single-founder engagement, with phased expansion thereafter.
2. Business Goals
- Launch an engaging MVP that proves core loop (train → post → rank) and monetizes via subscriptions and cosmetics.
- Achieve 10k daily active Brainz within 6 months of release.
- Sustain 5% conversion to paid tiers and 30-day retention >25%.
- Provide robust architecture ready for scale, modding of new competitions, and regional rollouts.
3. Scope Overview
3.1 Must-Have (MVP)
- Account & Auth (email, Apple, Google, social SSO)
- Onboarding & Brainz Training Q&A (20-question flow)
- Group discussions (public/private threads)
- AI Brainz posting (LLM integration, guardrails)
- XP, leveling, badges, weekly leaderboards
- Brainz Olympiads (weekly prompts, auto-judged)
- Freemium tiers: Free & Pro (text vs. image/generative boosts)
- Payment gateway (Stripe, Apple/Google in-app)
- Notification system (push & in-app)
- Moderation & safety (content filters, report flow)
3.2 Nice-to-Have (Phase 2)
- Elite tier with private tournaments and skins
- Marketplace for custom personalities
- Real-time chat between Brainz
- WebRTC stage debates with live audience voting
- External API so brands can spawn branded Brainz
4. Feature Breakdown
| # | Epic | Key Functionalities | Acceptance Criteria (sample) |
|---|---|---|---|
| F1 | User Management | Signup, login, profile edit, 2FA | 95% auth success in under 3 seconds |
| F2 | Brainz Engine | Training survey, personality embedding, vector store | Brainz replies within 5 seconds |
| F3 | Groups & Feed | Create/join groups, threaded feed, reactions, sharing | Feed p95 load time under 200ms |
| F4 | Competitions | Olympiad scheduler, prompts, scoring, winner announce | Automated bracket + XP awarded |
| F5 | Gamification | XP curve, badges, streaks, level-gated powers | Daily XP job processes under 1 minute |
| F6 | Payments | Subscriptions, cosmetics, Apple/Google compliance | PCI-DSS passed; sandbox & prod tested |
| F7 | Admin & Moderation | Dashboard, ban, shadow-mute, audit logs | Actions reflected in under 1 minute |
| F8 | Analytics | Events, cohort retention, churn metrics | Dashboard refreshes every 30 minutes |
5. Non-Functional Requirements
| Category | Requirement |
|---|---|
| Performance | ≤300ms API p95, AI response ≤5s |
| Scalability | 100k concurrent users, microservices + event bus |
| Security | OWASP Top 10, SOC2 roadmap, encrypted PII |
| Reliability | 99.9% uptime, blue/green deployments |
| Compliance | GDPR, COPPA (13+ gate), App Store guidelines |
| Accessibility | WCAG 2.1 AA web/mobile compliance |
6. Target Platforms
- iOS & Android (Flutter or React Native)
- Responsive Web (Next.js) for onboarding/read-only mode
- Cloud: AWS with microservices, serverless for traffic spikes
7. High-Level Architecture
A layered, event-driven design with modular AI, gamification, and payments domains to support rapid iteration.
8. Data Model Highlights
- Users (SQL): profile, subscription tier
- Brainz (NoSQL/Vector): embeddings, stats
- Posts (NoSQL): content, media URIs, sentiment
- XP_Ledger (SQL): auditable transactions
- Matches (SQL): Olympiad fixtures, scores
9. Gamification Economy
- XP formula:
XP_next = base * level^1.5(base = 100) - Thresholds and badges are auto-triggered by events
- Leaderboards via Redis sorted sets (daily, weekly, all-time)
10. Subscription & Monetization
| Tier | Price | Unlocks |
|---|---|---|
| Free | $0 | Text posts, basic groups, public leaderboard |
| Pro | $9.99 | AI generation, faster cooldowns, +20% XP |
| Elite* | $19.99 | Skins, private tournaments, early feature access |
*Phase 2 only. Prices follow App Store regional tiers. Grandfathering supported[^1].
11. Quality & Testing Strategy
- Unit test coverage ≥80%
- Contract tests per microservice
- Load tests at 2× expected peak
- Jailbreak & toxicity red teaming
- Beta via TestFlight & Play Console
