What is Studyh

Studyh is an AI tutor for active study. It turns materials into questions, evaluates your answers, and schedules reviews based on your performance.

Numeric facts

  • 5 input formats: PDF, TXT, Markdown, pasted text, and a typed topic.
  • 8 study steps, from sending material to review.
  • 7-day refund guarantee for eligible purchases.

Practical comparison

Traditional tools often hand you summaries or ready-made answers. Studyh asks you to answer first, compares your response with the material, points out gaps, and organizes the next review.

How it works

  1. 01Step 1: send a PDF, TXT, Markdown file, pasted text, or typed topic.
  2. 02Step 2: answer questions before looking at the explanation.
  3. 03Step 3: receive corrections, examples, and gap signals.
  4. 04Step 4: review again according to your performance.

ANSWER BEFORE THE EXPLANATION

Why is oxygen important in the final stage of cellular respiration?

I think it receives the electrons...
GAP FOUND

Your answer identified the role of oxygen, but did not explain its connection to the electron transport chain.

Limits and responsible use

AI evaluation supports study; it is not objective proof of mastery. Results vary with the quality of the material, the clarity of the answer, and the question context. For important decisions, check the content against reliable sources.

Applying active study in practice

Start with a concrete goal, such as reviewing a chapter, preparing for an exam, or recovering the main points from a lesson. The material you send should be complete enough for the questions to represent what you actually need to study. When a source is incomplete, treat the questions as a starting point rather than full coverage of the topic.

On the first pass, answer without looking at the material. This makes the difference visible between recognizing a familiar sentence and retrieving an explanation. An incomplete answer is not a failure: it shows which part needs another attempt, an example, or a simpler explanation.

After answering, read the correction carefully. Compare your response with the central concepts, numerical details, and relationships between ideas. Record important doubts and check external sources whenever the subject requires precision, especially for academic, legal, medical, or professional content.

Reviews should follow performance, but no algorithm perfectly predicts an individual's moment of forgetting. Use scheduling as guidance, adapt the pace to your routine, and practice again when you notice uncertainty. The quality of retrieval effort remains the student's responsibility.

Studyh is designed to reduce the operational work of studying — turning material into questions, organizing feedback, and indicating what deserves attention. It does not replace classes, teachers, books, primary sources, or the student's judgment about what matters for an exam.

Frequently asked questions (FAQ)

Does Studyh have a free plan?

No. Studyh is subscription-only; creating an account costs nothing, but AI features require a plan.

Which formats are supported?

PDF, TXT, Markdown, pasted text, and a typed topic.

Does AI guarantee that I learned?

No. It helps you practice, identify gaps, and review with more intention.
