Pricing FAQ
Does $29/mo really include all 12 languages?
Yes. One subscription gives you full access to every launch language, every CEFR level A1 through C1 at launch (C2 in Phase 2), and every Phase-2 language when it ships (Dutch, Polish, Greek, Vietnamese, Thai, Indonesian, Hebrew, Tagalog). No per-language fees, no premium upgrade tier.
How does the AI scoring on writing and speaking work?
Writing is scored against the official CEFR analytic rubrics (range, accuracy, coherence, register). Speaking uses per-language phoneme alignment (Montreal Forced Aligner) plus tone evaluation for Mandarin, pitch-accent for Japanese, vowel-harmony for Turkish, and stress placement for Russian. Each scoring engine is calibrated against native-speaker reference distributions. Calibration data is published alongside the product.
What's the difference vs. Duolingo or Babbel?
Duolingo and Babbel charge per language and don’t grade writing or speaking with AI. AccelaStudy AI Languages charges once for all 12 languages, grades all four CEFR skills against the official rubrics, transfers learned concepts across language families, and predicts your readiness for the real CEFR exams (DELE, DELF, JLPT, HSK, etc.) before you book one.
Which dialects / variants ship at launch?
Spanish: Latin American neutral. French: Metropolitan. German: Standard Hochdeutsch. Italian: Standard. Portuguese: Brazilian. Russian: Standard. Arabic: Modern Standard (MSA). Mandarin: Simplified PRC. Japanese: Standard. Korean: Seoul Standard. Hindi: Standard Devanagari. Turkish: Istanbul Standard. Phase 2 adds Iberian Spanish, European Portuguese, Traditional/Taiwanese Mandarin, and Egyptian/Levantine/Gulf/Maghrebi Arabic.
What payment methods do you accept?
Major credit and debit cards via Stripe, Apple Pay, Google Pay. Regional payment partners launch with the product: UPI in India, Alipay/WeChat Pay in China, Pix in Brazil. Regional pricing tiers (PPP-adjusted) for emerging-market countries.
Can I switch between languages mid-month?
Yes. There’s no “active language” lock. Study Spanish in the morning and Japanese in the evening if you want. Your adaptive profile tracks each language independently.
Is there a free trial?
Yes. When AccelaStudy AI Languages launches, every plan starts with a 7-day free trial. Credit card required to start. Your card is charged your plan's price when the trial ends unless you cancel first. No minimum commitment after that, either. One month of AccelaStudy AI Languages costs less than two months of Babbel for a single language and a fraction of one Pimsleur tape set.
Will the price change?
Pricing for the international market is still being finalized. The current planned USD price is $29/mo and may change before subscriptions open.
