MondLab is an online tool for Genshin Impact players that helps organize a character roster and explore team recommendations. Players can select the characters they own in the Roster tab, then view suggested teams for Spiral Abyss, Stygian Onslaught, and Imaginarium Theater, as well as advice related to current banners and pull priority. The site also supports sharing a roster or an individual team through a link, with options to copy the link or share it on social platforms.

Users can adjust character power multipliers to reflect differences in artifacts, weapons, and constellations, helping tailor recommendations to their account; the tool also explains that adjustments for four-star characters are not recommended. Additional features include the option to show unowned characters, remove characters from a roster, and consult information about how recommendations work and how data is handled. MondLab is presented as a beta product, with an updates area for development notes and data changes
