CAVOK: Study Buddy
Private AI that answers only from your own textbook
CAVOK: Study Buddy is a native Mac app for students with a textbook and a deadline. Drop in your own PDF and ask questions in plain language. CAVOK answers using only that book and cites the exact page. If it doesn't know, it says so, no guessing, no filled in gaps. Everything runs on your device by default. No account required. Turn on cloud mode with your own API key for deeper, adaptive answers. Nothing passes through us because we don't run servers. One-time purchase, $14.99.
Hey Product Hunt, I'm John, a flight instructor who also builds local-first AI systems.
This started in ground school. Students could open the technical manuals and find the exact paragraph with the answer, they just didn't read it that way. They'd come find me on a break or after class with something that had been sitting right there in the text the whole time.
CAVOK is built on one rule: the document teaches the system first, the user teaches the system second, the developer teaches the system never. It answers from your textbook, or tells you it isn't there. No guessing, no filled in gaps, no hallucinated citations.
It's a native Mac app, one-time purchase, no subscription. Local by default, nothing leaves your Mac unless you turn on the optional cloud mode with your own API key.
Happy to answer anything about how it works.
If you want to test it and leave a review, comment below or DM me, I've got a few free download codes set aside for people who do.
