Best AI FAR/AIM Apps (2026): RegBrief, Aviator Intelligence, ChatFAR and FAR/BOT Compared
The AI FAR/AIM apps that cite the regulation: RegBrief, Aviator Intelligence, AeroCopilot ChatFAR, FAR/BOT, Glide AI and more, with prices, free tiers and a 3-question test.
Short answer: for most student pilots, start with RegBrief's free FAR/AIM library and add one AI tool that cites its sources. If you want answers grounded in a published textbook, Aviator Intelligence by ASA draws on ASA's 2026 FAR/AIM. If you already plan flights in AeroCopilot, its AeroCopilot ChatFAR mode is included. Whatever you pick, open the cited section and read it yourself before you rely on the answer.
Updated October 30, 2026: prices and features checked on the vendors' own sites (dates in the table). We list only tools that answer from aviation sources and show where the answer came from.

Which one fits you
- You want the regs on your phone, free, offline: RegBrief. The free tier is the whole library with search; pay only if you want AI explanations or cited Q&A.
- You want answers from a book your school already uses: Aviator Intelligence by ASA. It also writes quizzes with answer keys, which helps before the written test.
- You already use AeroCopilot for planning: AeroCopilot ChatFAR. Five free messages a day covers an occasional lookup.
- You ask questions out loud or while flight planning: Glide AI, which mixes regs with live weather.
- You're prepping a private pilot checkride: Arien Aviation or Sporty's ChatFAR inside the course, since both tie regs to the ACS and oral prep. For oral practice itself, see the best AI checkride oral prep apps.

A 3-question test to run on any of them
Before you trust an app, ask it three questions you can check yourself on the eCFR. Clocks fall back on November 1, 2026, so the first one matters this week.
- "Which definition of night applies to position lights, logging night time and night passenger currency?" A good answer gives three different ones: sunset to sunrise for lights (14 CFR 91.209), end of evening to beginning of morning civil twilight for logging (14 CFR 1.1), and 1 hour after sunset to 1 hour before sunrise for carrying passengers (14 CFR 61.57(b)).
- "When is my flight review due?" It should say the review must fall within the preceding 24 calendar months (14 CFR 61.56(c)), counted to the end of the month, not 24 months to the day.
- "What fuel reserve do I need for a VFR flight at night in an airplane?" 45 minutes at normal cruise, versus 30 by day (14 CFR 91.151).
If the app gets one wrong, cites a paragraph that doesn't say what it claims, or gives no citation at all, treat its answers as a starting point only. Our guide Can ChatGPT answer FAR/AIM questions? walks through the night definitions in detail.
What to keep in mind
- None of these apps is an FAA publication. The official text is on eCFR (14 CFR) and faa.gov (the AIM).
- Apps that bundle the text can lag an amendment. RegBrief says it checks the eCFR daily and flags changed sections on Plus.
- For a genuinely ambiguous case, read FAA Chief Counsel legal interpretations and ask your CFI.
Not legal advice. AI tools are study and reference aids; the official regulation text, your CFI and the FAA are the authorities. Cockpit Index isn't paid by any app on this page.

Frequently asked questions
What is the best AI app for FAR/AIM questions?
It depends on how you study. RegBrief gives you the full FAR/AIM free and offline on iPhone, with cited AI Q&A on its $5.99/mo Pro plan. Aviator Intelligence answers from ASA's 2026 FAR/AIM with citations for $19.99/mo after a 7-day trial. AeroCopilot ChatFAR is included in AeroCopilot's plans, with 5 free messages a day.
Is there a free FAR/AIM app with AI?
RegBrief's free tier has the whole FAR/AIM with search but no AI. Free AI options are limited: AeroCopilot's free plan allows 5 AI messages a day, Glide AI allows 5 questions an hour, FAR/BOT gives 3 prompts, and Arien Aviation gives 15 replies.
Do AI FAR/AIM apps replace the official regulations?
No. They are study aids. The current text of 14 CFR is on the eCFR (ecfr.gov) and the AIM is on faa.gov. Open the cited section and read it before relying on an answer.
Are these better than asking ChatGPT?
They answer from a defined set of aviation documents and show the source, which makes mistakes easier to catch. A general chatbot can invent citations. Either way, check the regulation yourself.
Which AI FAR/AIM app works offline?
RegBrief's library and search work fully offline after a one-time download; only its Pro cloud Q&A needs a connection. The other apps here need internet for AI answers.
