## What is Demostra?

Reading a topic makes you feel like you understand it. Explaining it out loud is where the gaps show up.

That is exactly what Demostra measures. You explain a topic aloud, and the app marks it proven, blurry or repeat based on what you actually said. Not a score, the gap: it names what you left out.

HOW IT WORKS

1. Add your goal and its topics. An exam, an interview, or your own learning plan.
2. Pick a topic and explain it out loud. Forty seconds is enough.
3. What you said gets evaluated: which point you made, which one you skipped.

WHAT YOU GET

A readiness board. Every topic as it really is, on one screen: proven, blurry, repeat. There is no "you are 85% ready" number, because we do not know such a number.

A reinforcement queue. Topics you explained well come back at long intervals; shaky ones return early. Not every note comes back, only the ones worth revisiting.

A study timer. Start it with a label, stop it, keep the record. Forgot to start it? You can state the time afterwards, and that record is marked as self-reported and stays out of shared rankings.

A friend streak. On days you both show up, the streak grows together. It does not measure who studied more, it measures your own line.

Patterns. Which hours you explain better, and which topics fade as time passes over them.

YOUR VOICE STAYS ON YOUR DEVICE

Your speech is transcribed on your device. No audio is sent to a server or stored. The evaluation runs on the transcribed text.

You can download your data at any time and delete your account from inside the app.

WHO IT IS FOR

Students preparing for exams, candidates preparing for interviews, and anyone who wants what they read to actually stick. Demostra is for ages 16 and over.

WHAT IT IS NOT

Not a question bank, not a set of solved tests, not an app that teaches you the subject. It does not explain topics to you; it listens to you explain and shows you where you fell short.
