nbnhhsh is a browser extension that translates Chinese pinyin acronyms and internet slang into their full phrases. It operates entirely on the client side, using a precompiled dictionary bundled with the extension to perform lookups without server round-trips after the initial load.
The project distinguishes itself through a community-driven dictionary that accepts user-submitted definitions through a review queue before merging them into the main dataset. It provides text selection lookup on any webpage, allowing users to highlight pinyin initialisms and see their expanded meanings, and can be embedded into any site via a simple code snippet.
The tool covers pinyin acronym decoding, Chinese internet slang translation, and slang definition submission, all within a browser-based text translation workflow. The dictionary is maintained as a static JSON bundle, with a moderation queue managing pending user contributions before publication.
