About us
Making video learning
actually work.
Klaara was born from a simple frustration: hours of video, minutes of insight. We're building the bridge between watching and understanding.
Our mission
Turn the world's video into the world's best classroom.
There are over 800 million educational videos on YouTube alone. The knowledge is there — but the format doesn't match how people actually learn. Klaara uses AI to restructure video content into readable, skimmable, exportable formats that fit any workflow.

Our values
What drives us
Learn by doing
We believe the best tools disappear into your workflow. Klaara doesn't add steps — it removes them.
Accessible by default
Education should work for everyone. Every feature we build is tested across abilities, devices, and bandwidth levels.
Privacy first
We never sell your data or train on your content. Your learning history is yours — always encrypted, always deletable.
Speed is respect
Your time matters. We obsess over latency so a 3-hour lecture becomes a 30-second summary, not a 30-second wait.
