How Vidi Works

The science behind building vocabulary that actually sticks.

Three steps

1. Type a word. Vidi handles translation, grammar, and pronunciation.
2. Pick an image that means something to you. That choice is the learning.
3. Review when ready. FSRS schedules the next look based on how it went.

Vidi is a vocabulary learning app, not a full language course.

Research behind the method

Spacing practice across separate sessions can help you remember what you learn. Vidi uses FSRS to estimate review timing from your ratings. Review times vary.

Picture recognition depends on the images and the task. These studies do not establish a fixed memory improvement for Vidi.
