## What is CFR AI?

CFR AI - Title 4 is built for people who need a focused, modern workspace for Code of Federal Regulations Title 4 research and organization.

Ask questions about Title 4 and get AI-assisted responses designed around current eCFR source material, citations, and a clear trust layer. The app also gives you a productivity hub for saved answers, deadlines, reminders, notes, and title-specific follow-up work.

Key features:

Live Title 4 CFR Chat
Ask natural-language questions about Accounts and receive structured AI responses with citation-oriented source context from current eCFR data.

eCFR Trust Layer
Responses are designed to highlight cited CFR sections, source context, and professional-use reminders so users understand what should be verified before relying on an answer.

CFR Change Monitor

Accounts Organizer

Advanced Calendar
Use an iOS-style calendar workspace with month, week, day, and agenda views for review blocks, appointments, deadlines, and saved chat answers.

Reminders

Notes
Save research notes, AI answers, citations, checklists, tags, folders, and longer CFR notes without losing important context.

AI Action Buttons
Save useful chatbot responses into calendar items, reminders, notes, and organizer workflows so research can turn into action.
