Features & Capabilities

Speak aloud and record. AI will correct your pronunciation.

Simply listening won't make you fluent.

Shadow is a learning app specializing in shadowing, where you repeat the cycle of "listen → imitate and speak aloud → record and check" for each task.

■ AI corrects your pronunciation in Japanese
After sending a recording, it displays each word in a color-coded format, indicating "correctly said / sounded like a different word / not said correctly." It then provides feedback in Japanese, pointing out the next area to improve. Each task is designed to be completed in four practice sessions, and you can see your progress from the first attempt in a graph.

(Detailed AI analysis is unlimited with the annual plan (fair use restrictions may apply to prevent misuse), and limited to 3 times every 24 hours with the monthly plan and during the free trial. You can practice and record as many times as you like.)

■ Continuous length, continuous topics
Each task is 20-45 seconds long. You can complete one while waiting at a traffic light or during a single train stop. 12 genres: Psychology, Business, AI, Life Abroad, History, Science, Sports, Romance, Education, Health, World Culture, and English Learning. 66 materials and 119 exercises. Includes English audio, Japanese translation, and important expressions.

■ For those still struggling with English:
The "Basic" tab offers a beginner's course (30 topics, 3 steps) starting with 10-second middle school English lessons. You won't be confused about where to begin.

■ Mechanisms to help you stay motivated:
Suggests one lesson to do today / Weekly target days / Learning reminders / Consecutive learning days / Learning calendar. Visually track your daily progress.

■ For those who:
- Have struggled to stick with passive listening materials
- Can score well on tests but can't speak
- Lack confidence in pronunciation and don't know how to correct it
- Want to engage with English during commutes or breaks

■ Pricing
After a 7-day free trial, the monthly fee is ¥1,980 (AI analysis up to 3 times every 24 hours) or the annual fee is ¥19,800 (unlimited AI analysis, ¥1,650 per month). You can cancel at least 24 hours before the end of the free trial period to avoid any charges.

*Subscription to the in-app is required to use the learning materials.
