Use a source hierarchy
For Claude-specific facts, primary sources are Anthropic and Claude properties: platform docs, help-center articles, privacy pages, release notes, and terms. For legal and regulatory claims, primary sources are government publications and official notices.
Personal workflow posts can be useful inspiration, but they should not be the basis for current claims about availability, privacy, copyright, or policy. Those claims change and need owners.
This site cites primary sources wherever it makes factual claims about Claude features, data handling, copyright registration, or deceptive AI claims.
Claude product and prompting sources
Use Anthropic platform docs for prompt engineering and model-platform concepts. Use Claude Help Center articles for consumer and app-surface features such as projects, artifacts, research, skills, and Microsoft Office add-ins.
When a help-center article has a publish or update date, cite it. When it does not, include your access date in your own notes.
Privacy and retention sources
Use the Anthropic Privacy Center for data-use and retention claims. Separate consumer products from commercial products because their defaults and controls differ.
For sensitive writing, cite the exact policy page that applies to the product surface and plan being used.
Copyright and marketing-law sources
Use the U.S. Copyright Office AI hub, its Part 2 copyrightability summary, and the Federal Register registration guidance for AI-assisted authorship. Use FTC releases and business guidance for deceptive AI claims and fake review risks.
This site does not provide legal advice. It provides source-grounded workflow guidance so writers know which questions to raise before publication.
