Launching KnowFlow: Building a Modern Flashcard System
Today marks the official launch of KnowFlow, a modern flashcard system designed to help you actually remember what you learn.
The Problem We're Solving
Flashcards are deceptively simple. Everyone knows they work for memorization, but in practice, they rarely get used consistently. Why? Because creating cards is tedious, and remembering to review them is even harder.
KnowFlow addresses both issues:
- Friction in card creation - With AI-powered card generation, you can create quality flashcards in seconds
- Friction in reviewing - Our spaced repetition algorithm ensures you review cards at optimal intervals
What Makes KnowFlow Different
AI-Powered Card Generation
Creating flashcards from scratch takes time. KnowFlow's AI can generate high-quality flashcard pairs from any text you provide. Whether you're studying textbook chapters or learning a new skill, AI helps you build your deck faster.
Free tier users get 10 AI generations per day, while Plus and Pro subscribers enjoy unlimited AI card generation.
235 Curated Sample Decks
Not sure where to start? Browse our curated library of 235 flashcards across 5 themed decks:

Clone any deck with one click and start reviewing immediately.
Science-Backed Spaced Repetition
KnowFlow uses the SM-2 algorithm, which has been proven to optimize long-term retention. The system automatically schedules your reviews based on how well you know each card.
Easy cards get reviewed less frequently, while difficult cards come back more often. This timing helps with memory consolidation and ensures you're not wasting time on things you already know.
Cloud-First, Always Synced
No more losing your progress. Everything syncs automatically across devices. Start studying on your laptop, continue on your phone.
Built for Teams (Pro Plan)
The Pro plan includes Organizations, which are perfect for classrooms, study groups, or team training. You can share decks with your team, enable collaborative learning, and manage role-based permissions.
