Before you build an AI feature, answer two questions:
Guides adding AI-powered features to SaaS products: LLM API integration, RAG, AI assistants, prompt engineering, cost management, and patterns like smart drafts, summarization, categorization.
Audits pre-launch AI features across 6 dimensions—model selection, data quality, cost, monitoring, failure UX, optimization—grading readiness and blocking shipment of broken products.
Architects AI wrapper products around OpenAI/Anthropic APIs into focused, monetizable tools. Covers prompt engineering, cost optimization, rate limiting, UX, and business strategy. Activates on AI wrapper/GPT product mentions.
Share bugs, ideas, or general feedback.
Before you build an AI feature, answer two questions:
Most PMs skip #1 and regret #2 later.

AI COST CHECK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AI features have marginal costs that scale with usage.
Model this BEFORE building, not after launch.
What AI feature are you considering?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
/ai-cost-check [feature-name]
Examples:
/ai-cost-check "product recommendations" - Calculate recommendation costs/ai-cost-check "email composer" - Model email generation economics/ai-cost-check --compare - Compare cost across different modelsAI products have marginal costs that scale with usage. Every user interaction costs money. Model this BEFORE building, not after launch when you're hemorrhaging cash.
| AI Cost as % of Revenue | Status | Recommendation |
|---|---|---|
| <15% | Sustainable | Build it |
| 15-30% | Viable | Build with optimization plan |
| >30% | Unsustainable | Don't build (or fundamentally rethink) |
FEATURE DETAILS:
- Model: GPT-4 Turbo
- Calls per recommendation: 1
- Input: 1,500 tokens
- Output: 300 tokens
COST BREAKDOWN:
Per request: $0.024
Per user/month: $2.16
| Scale | Monthly Cost | Your Revenue | AI % of Revenue |
|-------|-------------|--------------|-----------------|
| 100 | $216 | $2,000 | 10.8% |
| 10K | $21,600 | $200,000 | 10.8% |
VERDICT: Sustainable at 10.8% of revenue
OPTIMIZATION PATHS:
1. Caching (saves 40-60%): $8,640/month at 10K users
2. Model selection (saves 70%): Use GPT-3.5 for simple cases
| Model | Input | Output |
|---|---|---|
| GPT-4 Turbo | $0.01/1K | $0.03/1K |
| GPT-4o | $0.005/1K | $0.015/1K |
| GPT-3.5 Turbo | $0.0005/1K | $0.0015/1K |
| Claude 3.5 Sonnet | $0.003/1K | $0.015/1K |
| Claude 3 Haiku | $0.00025/1K | $0.00125/1K |
