Common questions
Do I need to know anything before starting?+
No. The AI tutor adapts to your level and builds vocabulary from the ground up.
How is this different from Duolingo or Babbel?+
Most apps gamify with streaks and pre-packaged lessons. Allomorpheus is built by a computational linguist and takes a structural approach — understand how the language works, generate infinite expressions.
Can I use Allomorpheus as an Anki language learning app?+
Yes. Every word and phrase you save converts to a ready-to-use Anki deck with one click — conversations, lyrics, articles, grammar lessons. Standard Anki format, no manual card creation.
What happens after my free trial?+
Choose Monthly ($15), Quarterly ($39), or Annual ($99). Cancel anytime from the billing portal. No surprise charges.
Can I switch languages?+
One subscription covers all ten languages. Vocabulary and progress are tracked independently for each.
Is my data private?+
Yes. No ads, no tracking cookies, no data sold. Chat content is used only for your personal learning.
Can I cancel anytime?+
Yes. Cancel from your billing portal — no emails, no calls. You keep access until the end of your billing period.
