When to Build vs When Not To

Build a free tool when:

Search volume exists for "[topic] calculator/generator/checker" (> 500/month)
No excellent free alternative exists (or you can be 10x better)
The tool naturally connects to your paid product
You have engineering resources to build AND maintain it
The tool produces shareable, bookmark-worthy output

Do NOT build when:

A well-established free tool already exists and is sufficient
The tool would be a thin wrapper with no unique value
You cannot maintain it post-launch
The tool requires data you do not have or cannot access
Total addressable search volume is < 200/month
