Smart Lecture Keyboard

Never miss a lecture again

Lektr is a keyboard with a built-in camera and mic. Set your iPhone or iPad in the charging cradle, point it at the board, and capture the lecture while you take notes.

How Lektr Works

Active Note-Taking, Powered by Capture

🎙️ Capture While You Take Notes

The keyboard's built-in camera and mic record the lecture while you type or use Apple Pencil on your iPad. Every slide, diagram, and equation is captured automatically.

🔗 Your Notes, Synced to the Recording

Every note you type or write is timestamp-linked to the exact moment in the recording. Tap any note and the lecture jumps to that second — slide, audio, and your notes all together.

📚 Categorize, Group, Study

Your notes are automatically organized by topic, tagged by concept, and grouped into study decks — ready to share with classmates. Search for any term and Lektr returns your notes linked to the exact lecture moment.
