Hard-won warnings
Common mistakes.
- 01
Chat-text-first products in a speaking market: speech is the differentiator and the moat
- 02
Launching many languages with thin content instead of one pair with depth
- 03
Generic LLM tutors without level control, which overwhelm beginners within a week
Regulated space : read this first
- Voice data consent and retention (GDPR-sensitive biometric-adjacent data)
- Children's versions need child-privacy compliance
- Accessibility for hearing/vision differences

Differentiation
Majors own gamified vocabulary; the gap is confident speaking. Products that make real conversation practice comfortable (patient, level-aware, pronunciation-aware) serve the actual goal learners quit over.
How Novistu fits
Venture build for the speech loop and progression engine.
Founder questions.
Not on vocabulary gamification. On speaking confidence for specific languages and use cases (work, exams, relocation), focused products beat generalists consistently.
Accent-tolerant enough to encourage rather than frustrate: test with real learner accents, not just native speakers. This is the number-one churn driver.
Pairs with demand the majors under-serve or learner populations you can reach: heritage languages, business-language pairs, exam-specific learners.
