— features

Built to make studying smarter, not louder.

Six tools, one quiet workflow. Every feature is built around a single question: will you still know it next month?

01 — Input

Paste a YouTube URL. Walk away with a deck.

Captions are pulled, dedup'd, and turned into question-and-answer cards by Gemini 1.5 Flash — preserving the lecture's structure, not flattening it.

27 / 42 cards
02 — Schedule

SM-2 spaced repetition that actually sticks.

We review what you almost forgot — never what you already know. Saves hours, retains more.

03 — Tutor

An AI tutor that knows your deck.

Stuck on a card? Ask. The chat sees the source material, not just the question — so explanations are grounded.

Why does light affect this reaction more than temp?
Photosystems need photons to excite electrons — heat alone can't do that...
04 — Method

Active recall, not passive review.

Multiple-choice, free-response, and confidence ratings — every card asks you to retrieve, not just re-read.

MCQ
FREE
CLOZE
05 — Import

Bring your Anki decks. Keep your stats.

Drag-and-drop .apkg files. Notes, scheduling history, and cloze tags all preserved.

06 — Daily

A queue that tells you exactly what to review — and when to stop.

Open the app each morning. The queue is sorted, sized, and finite. No infinite scroll, no FOMO — just today's cards.

— why flazhai

Three things every other study app gets wrong.

01 / Speed

Other apps make you build the deck. We make the deck for you.

Most flashcard tools assume you have an hour to type out cards. You don't — you have a lecture to watch. FlazhAI listens for you.

others~ 90 min

02 / Memory

Cramming feels productive. Spaced repetition is.

The forgetting curve is real. SM-2 schedules each card right before you'd forget — turning 10 minutes a day into long-term mastery.

03 / Calm

FlazhAI tells you when you're done for the day. No streak shame, no FOMO push notifications — just today's cards, finished.

All caught up.

14 cards reviewed in 11 minutes. Come back tomorrow — your next batch will be waiting.

What people say when they actually remember what they studied

HeadlinerFILE №01
The Monday Knowledge Report hit different. It told me I was forgetting my Python fundamentals deck before I even noticed. Caught it just in time before my coding interview.

Kaneki Dev

Career changer, Toronto

FILE №02
I uploaded a 90-page research paper, got 30 flashcards, and retained the key findings for my thesis defence. I genuinely thought I'd have to read the whole thing again.

Abdullah Grizzy

Marketing Lead

FILE №03
I used to re-watch lectures 3 times before exams. Now I generate a deck, review for a week, and I'm done. My biochem grade went from a C to an A-.

Amara K.

Medical student, Lagos

The Struggle Detection feature is insane. I kept blanking on one concept and FlazhAI literally explained it three different ways until it clicked.

Good app. Took me a few days to build the daily review habit. Once I did, the retention improvement was real.
