Overview

Product summary

Review the store description, core capabilities, and common use cases.

This project is a community-driven fork of Yomichan, which is no longer maintained. Our primary objective is to maintain the project, ensuring it remains functional on the most recent browser versions and that any bugs are fixed.

Rikaitan turns your web browser into a tool for building Japanese language literacy by helping you to decipher texts which would be otherwise too difficult tackle. This extension is similar to 10ten Japanese Reader for Firefox and Rikaikun for Chrome, but it stands apart in its goal of being an all-encompassing learning tool as opposed to a mere browser-based dictionary. For the addon to work users need to download dictionary files from third party websites.

Popup dictionary for language learning

Helps users decipher difficult texts (especially Japanese) by providing instant popup definitions, furigana, and audio when hovering over or selecting words on web pages.

User installs extension and downloads dictionary files from GitHub. When browsing a webpage, hovering over text triggers a popup with definitions, furigana, and audio. Users can add words to Anki decks for spaced repetition learning. All processing happens locally in the browser.

Target users: Japanese language learners / Students using AJATT/Refold methods / Readers of Japanese web content / Anki flashcard users

Extension relies on external dictionary files that must be manually downloaded; analysis assumes these are free as per recommended-dictionaries.json
Anki integration requires a separate desktop application (Anki) and plugin (AnkiConnect) to be installed and running locally, which is outside the extension's scope
Some audio sources (LanguagePod101) may have their own terms of service, but the extension itself does not gate features behind payments

Monetization

No paid features detected

The extension is open-source (GPLv3 license) and free. There are no in-app purchases, subscriptions, premium tiers, or payment gateways (Stripe, PayPal, etc.) in the codebase. Dictionary files are downloaded for free from third-party sources. Anki integration is with a free desktop application.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local popup dictionary tool that operates entirely within the browser. It does not implement any login UI, nor does it redirect to a web service requiring an account. Dictionary data is downloaded from third-party static sources (GitHub releases) and stored locally. Optional features like Anki integration connect to a local desktop application (Anki + AnkiConnect plugin) via localhost, which does not require a web login to the extension itself.
