Build AI PM Skills Daily — Free →6 AI Product Building Blocks
1. Prompt design
Writing prompts that reliably produce good outputs across edge cases
2. Model evaluation
Testing output quality systematically before shipping
3. Fallback UX
Graceful handling when the model fails — don't just show errors
4. Hallucination management
Detecting and mitigating wrong-but-confident outputs
5. Latency / cost trade-offs
Which model, quality vs speed vs cost per call
6. User trust signals
Showing uncertainty, sources, opt-out — users trust systems that show limits
5 Common AI PM Mistakes
Shipping AI without evaluation pipeline — can't tell if output is degrading
Over-promising capability — 'AI that understands you perfectly' never delivers
Ignoring latency — 15-second responses kill UX even with great quality
Hiding that output is AI-generated — trust erodes when users find out
Not providing escape hatches — users need 'regenerate', 'edit', 'contact human' options
6 Trust Signals for AI UX
Clearly label AI-generated content — transparency builds trust
Show sources when applicable — 'based on document X'
Acknowledge uncertainty — 'I think...' beats false confidence
Easy to correct / regenerate — users know they can override
Preserve user voice — AI that makes everything sound same loses personality
Let users opt out — mandatory AI features frustrate power users
5 Evaluation Approaches
Golden dataset — curated examples with expected outputs
LLM-as-judge — using models to evaluate other model outputs
Human eval — expensive but irreplaceable for subjective quality
User feedback loops — thumbs up/down, explicit ratings
Automated regression tests — catch degradation in new model versions
FAQ
What's the biggest difference between building AI products and traditional products?
Non-deterministic outputs. Traditional products have consistent behaviour; AI products produce variable output each run. PMs must embrace this: design for variance, build eval systems, give users control to regenerate. PMs who expect deterministic AI behaviour ship fragile products.
What's the biggest AI PM mistake?
Shipping without evals. PMs get excited about a model that works on 5 demo inputs and ship to users who hit the long tail where it fails. Great AI PMs build evaluation pipelines before shipping, not after. An AI feature without evals is flying blind.
