CFR AI – Title 21

Acerca de esta app

CFR AI – Title 21 is a specialized productivity tool designed for professionals researching the U.S. Code of Federal Regulations Title 21 (Food and Drugs). The app combines an AI assistant with traditional organizational features to streamline regulatory compliance work.

Users can ask natural-language questions about Title 21 regulations and receive structured responses that include citations from current eCFR source material. A key feature is the ‘eCFR Trust Layer,’ which highlights cited sections and provides professional-use reminders, encouraging users to verify information against official sources before relying on it. The app explicitly states it is not affiliated with the U.S. government and that AI responses should not be treated as legal or professional advice.

Beyond AI chat, the app serves as a comprehensive workspace. It includes a Citation Builder for saving references, a Compare Versions tool to track regulatory changes over time, and a CFR Change Monitor for tracking updates. Productivity is supported by an advanced iOS-style calendar, organized reminder lists, and a notes system that allows users to save research notes, AI answers, and checklists. AI Action Buttons enable users to save useful chatbot responses directly into calendar items, reminders, or notes, turning research findings into actionable tasks.

The application requires an active subscription for full access to its features. It is available on iOS and macOS platforms.
