Texa is a personal AI STEM tutor built around real-time whiteboard-based interaction with voice communication, not a chatbot. The experience is like a student having a video call on a collaborative whiteboard with a human tutor. 

The project was initialized on Oct 26, 7 PM (GMT), and every single line of code was written in the hackathon period, including app code, docs, and branding (logos & image assets).

# The Problem:
Learning STEM is learning to do: sketching diagrams, plotting functions, solving problems step by step. Yet the help available to most students does not work that way:

- At home, many students have no one to ask. This is true everywhere, but it is sharpest in developing countries like mine, where many parents never attended school or left too early to help their children with homework, however much they want to. The student gets stuck in the evening, alone, and the gap quietly compounds. This is a problem I know firsthand.
- General-purpose AI chatbots aren't good enough for a struggling student.
- Human tutoring works, but has its limitations: Tutors are expensive, scheduled in advance, and sometimes unavailable exactly when they are needed most, so for most students that help simply never arrives.

# The solution

Texa is a patient, one-on-one AI tutor that speaks, writes, draws, and plots functions on a shared whiteboard. It runs on the devices students already have: phone, tablet, and computer. Available instantly, at the moment they get stuck, regardless of their parents' education, income, or where they live. 

Texa is not an answer machine. The student does not simply submit a problem and receive a finished solution. Texa first makes the student try and think for themselves, then assists only as needed with a hint, a leading question, one step at a time. Escalating only when they are genuinely stuck or have made a real attempt. The goal is not to complete the student's homework for them, but to build the understanding and confidence that let them solve the next problem on their own.

I'm well aware of the risks of AI hallucination. Although today's frontier models get perfect scores on most middle- to high-school STEM problems, the risk of AI hallucination is never 0 (this is true for all AI apps). With that in mind, the initial version of Texa recommends that students provide only problems they already have solutions to but don't understand how to solve, which is very common. This way they can verify Texa's guidance against the solution. We plan to add more grounding solutions to reduce hallucination risks and even add solutions where teachers can provide programs and pedagogy to the AI, which work with the student and report to the teacher with session recordings, which would eliminate the risk.

Complete documentation (Product Requirements and Technical Specification) is available in the repo.
