Testify AI

A quiz based on any file or video. Every question includes a lecture quote and a tappable timecode. Wrong answers feed into weak spots for another round.

Testify builds a quiz from your lecture and shows you, in the lecturer's own words, where every question came from.

A QUOTE FROM THE LECTURE, NOT A PARAPHRASE Every explanation carries the lecturer's actual words and a timecode. Tap the timecode and the video opens at that minute, so checking yourself takes a second instead of a hunt. If the quote is not enough, the full passage opens right there, without leaving the quiz.

YOU REDO WHAT YOU GOT WRONG Quizzes you scored low on collect into a separate list of weak spots, each with the date you last took it. You can retake any quiz as many times as you like, and flashcards from the same lecture give you a fast run through before an exam.

PROGRESS THAT DOES NOT FLATTER Your day streak, average and best score, how many quizzes you finished and how many lectures you added. For the week, the month or all time.

FOUR QUESTION FORMATS • Multiple choice: the classic test • Open questions: answer in your own words, AI grades them and explains what was missing • Flashcards: flip the card and grade yourself • Matching: pair terms with their definitions

Formats can be mixed inside one quiz.

A LECTURE CAN BE ALMOST ANYTHING A YouTube link, a video or audio recording, an article, a document, your own notes, a photo of the whiteboard. Or just a topic, when you have no material at hand. AI transcribes the recording, reads the text and writes questions from it. A minute or two later the quiz is ready.

THE QUIZ IS YOURS TO SHAPE The number of questions (3 to 30), the formats, the difficulty, and your own request ("focus on the second chapter", "make it easier"). Or change nothing and use your defaults.

ELEVEN LANGUAGES The interface and the questions come in Ukrainian, English, Spanish, Portuguese, German, French, Italian, Polish, Turkish, Russian or Bulgarian. Transcripts and quotes always stay in the original language: those are the lecturer's words, and translating them would make them someone else's.

BEFORE YOU INSTALL • An account is required: your lectures, quizzes and results are personal, and nothing is visible between users. • An internet connection is required, both to create a lecture or a quiz and to open one: all of it lives in the cloud, and the material is processed through the Google Gemini API. The device keeps only what the app needs to start: your sign-in, your settings and your latest list of lectures, so the home screen opens right away. • What you add is used only to build your quiz. We do not show it to anyone else and do not train models on it. • Testify is free to use: each month includes a set number of new lectures and quizzes. An optional Testify PRO subscription raises those limits, and the price for your country is shown on the PRO screen and in the App Store. • The subscription renews automatically until you cancel it. Cancelling is done in your Apple ID settings, not in the app. The monthly and yearly plans give the same access. • You can delete your account inside the app: Profile, then Delete account. Your lectures, quizzes and results go with it.
