  "faq": [
    {
      "q": "How is this different from other language apps?",
      "a": "Most apps and courses are fixed templates: the same path, the same words and the same videos for everyone. Alpha Tesseract is agentic. An AI agent keeps track of everything you have learned and how well you remember it, then picks each next step from your own mistakes, what is about to fade, and what unlocks the most. Two learners never get the same lesson."
    },
    {
      "q": "Which languages can I learn?",
      "a": "Right now: English, Tamil, Hindi, Telugu, Kannada, Malayalam, Bengali, Marathi, Spanish, French, German, Japanese and Arabic, with explanations in any of them. More languages are on the way."
    },
    {
      "q": "How does the coach decide what to teach?",
      "a": "It listens to every attempt and scores each sound. It remembers how well you know every sound and word, brings each one back just before you would forget it, and picks the next step from your own slips. Nothing is pre-written."
    },
    {
      "q": "Will I practise the same words every day?",
      "a": "No. Words and sentences are chosen fresh for what you are working on, so practice never turns into memorising a list."
    },
    {
      "q": "How much does it cost?",
      "a": "₹49 for your first month, then ₹249 a month. Or ₹1,499 a year, which works out to about ₹125 a month. Prices include GST. There is no free plan."
    },
    {
      "q": "How do payments work?",
      "a": "Payments are handled securely by Razorpay. You can pay with UPI, a debit or credit card, or net banking. Plans renew automatically, and we remind you at least 24 hours before every renewal."
    },
    {
      "q": "Can I cancel?",
      "a": "Yes, anytime. You keep access until the end of the period you have paid for, and you will not be charged again. See our refund and cancellation policy for details."
    },
    {
      "q": "Who is the coach?",
      "a": "Your coach is generated by Alpha Tesseract, not a recording of a real teacher. That is what lets her show you any word, in any of her languages, whenever you need it."
    },
    {
      "q": "What do I need to start?",
