Listing positioning

Rikaikun positions itself as a seamless Japanese dictionary that allows users to look up words without losing their reading flow. It emphasizes providing readings and English definitions via a simple hover action.

Inferred product pattern

A niche language utility using hover-based DOM parsing, currently struggling with technical stability and feature parity with its Firefox counterpart.

Review-backed pain points

Users frequently report that the extension stops working abruptly, fails to trigger on hover, or lacks the database depth to recognize essential names and places.

Observed feature gaps

Users have requested the ability to translate selected phrases rather than just hovered characters, more specialized internet slang/chattalk databases, and the ability to toggle off hiragana/katakana readings.
