We present Multilingwis2, a web based search engine for exploration of word-aligned parallel and multiparallel corpora. Our application extends the search facilities by Clematide et al. (2016) and is designed to be easily employable on any parallel corpus comprising universal part-of-speech tags, lemmas and word alignments. In addition to corpus exploration, it has proven useful for the assessment of word alignment quality. Loading the results of different alignment methods on the same corpus as different corpora into Multilingwis2 alleviates their comparison.
