AI Tutor App That Helps People Practise Speaking English
AI tutor app where learners practise speaking English with friendly avatar coaches that correct mistakes.
In plain English
Praktika is a phone app where people practise speaking a new language, mostly English, with an AI tutor. The tutor is a friendly cartoon character that talks with you, corrects your mistakes and tracks your level. It started by selling in Brazil as a way to get a better job, not just as English lessons. Learners pay a yearly or monthly subscription.
~$50M ARR, almost 500,000 paying subscribers, profitable (Sub Club podcast, Oct 2026)

Step-by-step setup
- Pick learners who need a language for work and sell the outcome (a better job), not just lessons.
- Build AI tutor characters that talk with learners, correct mistakes and track their level.
- Start in one country where demand is high, then copy what works to others.
- Yearly or monthly subscription; grow through many small creators making short videos, then turn winning videos into ads.

Realistic income
On RevenueCat’s Sub Club podcast (Oct 28, 2026), co-founder and CEO Adam Turaev said Praktika is at about $50 million in annual recurring revenue with almost half a million paying subscribers, a team of just over 40 people, and that the company is profitable. He said one creator video that drew about 30 million views across Instagram, TikTok and YouTube took the app from about $1M to $10-12M ARR in a single month, and that a roughly $100-a-year plan sold in Brazil because it was pitched as a path to a better job. Praktika is a venture-funded company with a team, not a solo side project. This figure is operator-reported, not independently verified, and may be out of date. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.
Risks
- Praktika is a venture-funded company with 40+ staff; a solo builder should not expect similar numbers.
- Duolingo and many AI tutor apps compete for the same learners, and copycats appear fast.
- AI voice and avatar costs grow with every minute of practice.
- Growth leaned on viral creator videos, which are hard to repeat.
- Startup cost and time to first dollar are not disclosed; the revenue figure is operator-reported.
