AniDachi vs Kosmi: A Kosmi Alternative for Anime Nights

Short Answer

Choose AniDachi for Crunchyroll, YouTube or Netflix nights in desktop Chrome where everyone watches on their own player, with synced playback, on-player chat and reactions, voice/video calls, and personal watch history. Choose Kosmi for a free, no-install hangout room with video chat, screen sharing and games that works on phones.

The two tools work differently. Kosmi brings the video into its room through a shared virtual browser or screen share. AniDachi leaves the video on each person's own Crunchyroll, YouTube or Netflix tab and syncs playback without re-streaming it.

At a glance

Kosmi: a free, browser-based platform for movie nights, game nights and virtual hangouts. Guests join from a link with no account and no extension. Rooms include a shared virtual browser that everyone can see and click, screen sharing with audio, voice, video and messaging, and games such as poker and retro consoles. Kosmi also has a mobile app.

AniDachi: a Chrome extension and web product for watchrooms on Crunchyroll, full YouTube watch pages and Netflix movie and episode pages in desktop Chrome. Rooms have live synchronized playback, on-player chat and reactions, voice/video calls, and personal watch history. Each person uses their own access to the video.

Feature comparison

When Kosmi is the better pick

• Someone in your group cannot install a Chrome extension, for example on a work laptop.
• Friends join from phones or tablets. AniDachi runs in desktop Chrome only.
• You want to host for free. AniDachi hosts need Plus or Pro.
• You want to watch Disney+, Hulu or Prime Video together, which AniDachi does not support.
• The night is more hangout than show: screen sharing, a shared browser, poker or retro games in the same room.

When AniDachi is the better pick

• Your group watches anime on Crunchyroll, which the Kosmi pages we checked do not mention.
• You want everyone on their own Crunchyroll, YouTube or Netflix player, synced, instead of watching a shared browser or screen share.
• You want chat and reactions on the player you are watching.
• You want a personal watch history of what you watched together.
• One host pays and friends join free, in rooms of up to 6 (Plus) or 15 (Pro).
