PartyDub is a browser-based party game platform built around playful voice performances and shared laughter. Its main game invites friends to dub over the same short video clip at the same time, without hearing one another, then watch the recordings and vote for the best version. Players can use their own footage, memes, or other clips they have the right to use. The game is free to play, requires no installation, and lets guests join with a room code; the host needs an account. Clips are sent directly from the host’s browser to players, and recordings are not stored or published.

PartyDub also offers Party Mimic, where players copy short sounds and receive a score, and Party Zoo, where they voice cartoon animals. These games share the same room-based format, with player limits that vary by game and hosting tier. For users preparing content, the site includes a free browser-based pack editor for Choicer Voicer and Voxalike, allowing users to mark speaking parts and export packs.
