Tori

Japanese Listening & SRS

Most apps give you a word list and a quiz. Tori gives you ears. Every sentence you save gets clear spoken audio, and Tori gives you four ways to hear it: with the screen off, out loud, inside a story, and in every flashcard review.

Free to start. No account and no credit card.

What Tori Does

Four ways to hear your own Japanese, plus the tools to build the sentence bank behind it.

Passive Listening, Screen Off

Hands-free practice from your own sentence bank. Headphones in, phone in your pocket. Loop an island, change the speed from 0.5x to 1.5x, and set a sleep timer.

Shadowing

Listen, then repeat out loud, one sentence at a time. Record yourself and play it back next to the model audio to hear the difference.

AI Stories at Your Level

Short Japanese stories written for your level: mystery, comedy, adventure, ghost story, travel mishap. Listen like a podcast, read along with furigana, and save any line.

Flashcards With SRS

Active recall from English to Japanese, scored by a spaced repetition system. Hard sentences come back sooner. Every card plays its audio, so review is listening too.

Your Own Sentence Bank

Paste Japanese you are reading, journal about your day, or generate question and answer pairs. Tori translates each sentence, adds furigana, and files it away.

Islands

Group sentences by topic: your commute, your job, the anime you are watching, the trip you are planning. Each island is small and finishable, so progress is easy to see.

Speaking Practice With AI

Talk with an AI tutor in 15 real scenarios, from the konbini to a job interview. Gentle corrections feed back into your sentence bank.

Streaks and Progress

A daily streak, a 365-day activity heatmap, and a mastery score for every island you build.

Two Engines

Cloud AI by default for the fastest results, or an optional on-device mode that runs the AI on your phone and works offline. Switch any time in Settings.

Made for Self-Study

Tori works from the Japanese you already care about, not a stock word list.

You want more listening time

Tori turns every sentence you save into audio you can review anywhere, including with the screen off.

You are studying for the JLPT

Build vocabulary from real material at any level from N5 to N1, then keep it with SRS flashcards.

You have years of anime or podcasts

Turn what you already recognize into Japanese you can actually say out loud.

You are doing immersion

Mine the sentences you meet, then keep hearing them until they stick.

Start Free

The free version includes your starter islands, one custom island, and the core listening, shadowing, and flashcard drills. Tori Pro unlocks unlimited islands and unlimited AI conversation practice, monthly or annually.

Hear Your Own Japanese

Tori is available now on Android. Install it, save a few sentences, and put your headphones in.
