No VPN, no Chinese account, no API key. Watch any Bilibili video with English (or 30+ other languages) overlaid on the player, or download a subtitle file for your own edit. 50 free credits at signup.
Pick the workflow that matches how you watch. Both use the same translation engine and the same 30+ target languages.
Install the VinnerVi browser extension, open any Bilibili video, click the extension icon, and pick your target language. Translated subtitles appear in real time on the Bilibili player, synced to playback. Since most Bilibili videos don't carry built-in subtitles, the extension transcribes the audio with AI first at 3 credits per minute. Translated subtitles are cached locally and reload the next time you open the video — useful for long drama runs and study material you'll rewatch.
Open vinnervi.com/subtitles, paste the Bilibili link (bilibili.com or bilibili.tv), pick a target language and a subtitle format (SRT, VTT, ASS, or TXT), and hit Generate. About 1–10 minutes later the finished subtitle file lands in your Jobs tab and your inbox. Drop the file into Premiere, Final Cut, DaVinci, VLC, or mpv — or keep it as a personal transcript.
Bilibili is the most prolific Chinese-language video platform — millions of hours of variety shows, gaming streams, anime fan content, documentaries, university lectures, and original drama series live there, almost none of it subtitled in any language other than Simplified Chinese. International viewers who want to follow a creator, study Mandarin, or watch a specific show typically end up wrangling browser plugins, fan-translation Telegram groups, or paid subtitle subscriptions — each of which solves one piece of the problem and breaks somewhere else.
VinnerVi handles Bilibili end-to-end. The browser extension overlays translated subtitles directly on the Bilibili player, the URL workflow gives you a downloadable subtitle file, and both paths work from anywhere in the world — no VPN, no Chinese phone number, no account on bilibili.com required. The extension supports Bilibili's multi-part series format in batch, so you can translate a whole drama season or a multi-episode tutorial playlist in one click rather than re-running the workflow per episode.
Most Bilibili videos run through audio-transcription mode at 3 credits per minute because the source rarely carries subtitles. Translation quality is best for Mandarin source content — the AI was tuned for natural conversational Chinese — and works well across the 30+ target languages, with English, Japanese, Korean, Spanish, and Russian being the most common pairings. Failed jobs (corrupted audio, unsupported codecs, deleted videos) refund automatically; you only pay for successful translations.
