Thaw

An iPad notebook that turns photos of a board into notes you can edit.

Take a photo of a board and Claude writes it into your notebook as real pen strokes, which you can erase, recolor or move. Write with Apple Pencil, record a lecture and work it into your notes, check a page for mistakes, and export to Obsidian.

Thaw Camera sends photos and recordings from your iPhone to your iPad. Thaw for Mac lets you read your notes and ask questions about them.
