Why Knowlark?
The science
You forget most of what you read within a week. Rereading barely helps.
Recalling knowledge works better, and spreading recalls across days beats one sitting. Cognitive psychologists rate these as the only two study techniques with strong evidence. Knowlark is built on both.
Enter, Knowlark
Knowlark makes you answer questions, which locks in knowledge for life.
Knowlark uses successive relearning: recall a concept until you get it right, then recall again days later.
Funner than flashcards
Flashcards make you build a deck before you can start. Knowlark generates novel questions on the fly.
How Knowlark compares
Flashcards remember. AI thinks. Knowlark does both.
| Flashcards | AI | AI + Knowlark | |
|---|---|---|---|
| Questions written for you | No | Yes | Yes |
| Asks novel questions | No | Yes | Yes |
| Works in the chat you already use | No | Yes | Yes |
| Remembers you between sessions | Yes | No | Yes |
| Retests you just before you forget | Yes | No | Yes |
| Tracks your progress | Yes | No | Yes |

Why I built Knowlark
I was trying to learn the payments code at work. I read it, and a week later I could not remember it.
Rereading did not help. Being asked did. So I built Knowlark to quiz me until the answers came without thinking.
