MVP Roadmap & Feature Prioritization

MVP: Personal prompt management with version control, basic organization, and multi-model testing for individual AI practitioners

Core Problem: AI practitioners waste 3+ hours/week managing scattered prompts across notes, chat histories, and spreadsheets

Must-Have Features: Prompt creation/storage, version control, basic multi-model testing (2 providers), folder organization

NOT in MVP: Team collaboration, advanced analytics, VS Code extension, API, enterprise features

MVP Success Criteria
  • User Success: Create, version, and test prompts across 2 models in <5 minutes
  • Business Success: 500 registered users (Month 1), 25% monthly active users (MAU), 5% conversion to Pro tier
  • Validation Goals:
    • 70% of users use versioning within first week
    • 40% test prompts across multiple models
    • Retention >40% at 30 days

Technical Implementation Strategy

Low-Code Acceleration

Authentication: Clerk (saves 5 days) Database: Supabase (saves 4 days) Hosting: Vercel (saves 2 days) Payments: Stripe (saves 3 days) Total Time Saved: 14 days → MVP in 5 weeks (vs 19)
AI/ML Components: • Prompt testing: OpenAI API (GPT-4) • Cost tracking: Anthropic API (Claude 3.5) • Monthly cost (100 users): $2.30/user • API cost breakdown: • Hosting: $20 | DB: $25 | AI: $150 | Auth: $25 | Email: $10

Risk Management & Contingencies

⚠️
LLM Provider Changes

Severity: High

Mitigation: Build abstraction layer for LLM providers

Contingency: Support 3+ providers at launch

💡
Low Monetization Adoption

Severity: Medium

Mitigation: Offer Pro tier with 2 free prompts for team testing

Contingency: Launch with "Pro for Teams" pricing

✅
Solo Founder Burnout

Severity: High

Mitigation: Build in 1-week buffer every 6 weeks

Contingency: Hire part-time UI designer at $20/hr
