## What is Learn Claude 90 Days Course?

Learn Claude through an independent 90-day course based on Anthropic's public documentation.

Each day has a different objective and guides you through feature explanations, syntax and structure, worked examples, copyable test prompts, hands-on tasks, expected results, success criteria, and retryable quizzes.

The course is available in English, Italian, Spanish, French, German, and Arabic, with right-to-left support. Progress, notes, and bookmarks stay on your device; no account or Claude integration is required.

The first 10 lessons are free. Monthly Access is a one-month auto-renewing subscription that unlocks all 90 lessons and study tools. Lifetime Access is a one-time purchase that permanently unlocks the same content.

This is an independent educational app based on Anthropic's public documentation about Claude. It is not affiliated with, endorsed by, or operated by Anthropic.
