Why it exists

Claude moves fast and most public guides go stale within months — wrong prices, deprecated models, half-true comparisons. We rebuild the same questions from scratch, with the date and method on the page, so an engineer mid-migration or a solo builder mid-feature can act on the number, not guess it.

Korean builders are particularly underserved: 87 articles cover Korean tax/contract/HR automation, the ~1.3× Korean token premium, and Korean payment friction.

How we work

• Dated. Every article has a visible Published or Updated date.
• Pricing verified. We mirror Anthropic's official pricing (platform.claude.com/pricing) and run a CI check that catches legacy prices in any new content or tool.
• AI disclosure. Each article includes an ai_disclosure in the frontmatter — drafted with Claude Code, edited and checked by a human.
• Method shown. Benchmarks and measurements come with the methodology and sample size on the page (see e.g. token methodology).
• Citable. Every page is a stable URL with structured data, suitable to cite in client decks or internal docs. See /citations for how to cite.
