Questions people ask.
Do you sell AI credits?
No. You buy Paths. One Path is one course: four units, about two hours. We meter the AI underneath silently so you never have to think about tokens.
What happens when I hit my monthly cap?
Axo tells you in plain words, and your count starts again on the 1st of the month. The Paths you have and Keep Sharp keep working. On Free or Plus, you can move up a plan.
Which voice reads on Free?
Axo’s own voice, the same one on every plan. Plus and Pro add eight more voices. With no connection, your phone’s built-in voice stands in.
How does the free trial work?
The yearly Plus plan starts with 14 days free, once per Apple ID. The app shows the day the trial ends before you start. Cancel before then and you pay nothing.
Is my document private?
Yes. A Path built from your own material belongs to your account, and no other learner sees it. Our server keeps the text so it can write your Bites. The privacy policy has the details.
Does Axo make things up?
A Path built from your document uses only what is in your document, and every question names its page. A Path about a book is built from public sources you can open. A Path from a typed topic comes from the AI’s general knowledge, so check anything that matters.
What is the Stream?
A swipe feed of short spoken clips made from the Bites you have learned, so review happens while you scroll. Clips on new ground, a word you held or a Path offered next, are counted per day by plan; clips from what you already learned are not.
Can I cancel?
Any time, from Settings in the app (the sliders at the top right of You, then Manage subscription) or in your iPhone’s Settings under Subscriptions. Your Paths and badges stay, and you go back to Free’s limits at the end of the period you paid for.
