Tanna

Tanna is a note-taking app that allows users to organize their notes in a visual manner while reviewing them with spaced repetition algorithms.

How does it work? First, the user can upload raw content in a variety of formats, including plain text, images, and documents. Then, with the assistance of an AI, the user can quickly add notes to a mind map within the app. The AI converts these notes into questions and answers. The user is periodically tested on these questions and answers to ensure they do not forget any information.

Each piece of information is tracked by a precise algorithm, which ensures that you are only revising content right before you are about to forget it. This can reduce study time by up to 90%, as you often waste time studying content that you already know well.

In addition, your notes are safely and securely stored in the cloud, so you can access notes from other devices and not worry about losing the device that your notes are saved on.
