What is photosynthesis?
Photosynthesis is the process by which green plants use sunlight, water, and carbon dioxide to make their own food (glucose) and release oxygen. It happens mainly in the chloroplasts of leaves.
Who discovered it?
Based on your uploaded textbook: Jan Ingenhousz (1779) demonstrated that plants release oxygen in sunlight, building on earlier work by Joseph Priestley.

For Sarc Education Foundation students — quick, visual, and beginner-friendly.

1 What is AI?

Artificial Intelligence (AI) is a way of making computers learn from data and make decisions, instead of being told every step. Just like you learn maths by doing many examples, an AI learns by seeing many examples too.

  • Data — the examples we give it (PDFs, text, images).
  • Model — the "brain" that learns patterns.
  • Prediction — the AI's answer to a new question.
DATA MODEL ANSWER

2 How does training work?

Training means showing the AI lots of examples so it learns patterns. SmartTrain AI does this in 3 simple steps:

  1. Read the PDF / text you upload.
  2. Split it into small "knowledge blocks".
  3. Index them so it can search & answer fast.
PDF / TXT → Extract → Chunks → Search Index

3 What is a chatbot?

A chatbot is an AI program that talks in natural language. When you ask a question, it searches its memory (the data you trained it on) and replies with the most relevant information.

SmartTrain AI uses a simple TF-style scoring search to find matching content — perfect for learning the basics before moving to advanced models.

4 Types of AI you should know

  • Narrow AI — does one thing well (e.g., spam filter, this chatbot).
  • General AI — can do many human tasks (still research-only).
  • Generative AI — creates new content: ChatGPT, image generators, music.
  • Machine Learning — AI that learns from data; used in YouTube, Instagram, Google.

Try this exercise: upload your science chapter PDF, then ask 5 questions. Notice how the AI answers only from your file — that's the power of focused training data!
