Every feature BiliBili offers — from the iconic bullet comment system to anime streaming, live broadcasts, offline downloads, and creator tools.
BiliBili is not simply another video platform. It combines a streaming library, a live broadcast service, a creator ecosystem, and a community interaction system into one app. The features work together in a way that makes the platform feel like a shared experience rather than a passive viewing service — which is exactly what keeps its user base so engaged.
This page covers every major feature available in the BiliBili app in 2026 — what each one does, how it works, and why it matters to the overall platform experience.

Bullet comments — known as danmaku (弾幕) in Japanese or 弹幕 in Chinese — are real-time viewer comments that scroll horizontally across the video screen as you watch. Each comment is anchored to a specific timestamp in the video, meaning it appears at the exact moment it was written about. When you watch a video for the first time, you see the same comments that viewers left weeks or months earlier — all appearing at the right moment.
This creates a genuinely shared viewing experience. Watching a plot twist in an anime episode, a clutch moment in an esports match, or a punchline in a comedy video feels communal because you see hundreds of other people reacting to the same moment simultaneously. Inside jokes build up, running commentary develops over time, and popular videos accumulate layers of viewer reactions that become part of the content itself.
Bullet comments can be toggled on or off at any time. When off, the video plays cleanly with no overlay. When on, the density of comments can be adjusted — lighter for casual viewing, heavier for the full communal experience. You can also filter comments by keyword or display style.
BiliBili's anime library is one of the largest available on any single platform. It covers seasonal simulcasts — new episodes released the same week they air in Japan — alongside a deep back catalogue of classic series. The library is organised by genre, season, studio, and popularity, making it straightforward to find both specific titles and new recommendations.
BiliBili has also invested in exclusive anime content — both licensed titles that stream only on BiliBili internationally and original productions commissioned and produced by the platform. These originals have gained significant recognition and introduced BiliBili to users who discovered it specifically through an exclusive title.
Subtitles are available in multiple languages for the majority of titles in the international library. The subtitle quality varies by title and translator, but popular seasonal anime typically receive fast, well-edited subtitles within hours of airing.
BiliBili's live streaming section runs 24 hours a day with broadcasts across dozens of categories. Gaming live streams are the most popular category — covering both Chinese-developed mobile games and international titles — but the platform also has strong communities built around music performance, digital art creation, cooking, fitness, and general talk streams.
The bullet comment system carries directly into live streams, giving viewers a way to interact with the broadcaster in real time. Popular streamers on BiliBili build dedicated communities around their channels, with regular viewers forming social connections through the shared comment space during live sessions.
