With whitelists, blacklists, channel switches, and timed mode, parents can precisely control what their kids watch on Bilibili — no more being led by the recommendation algorithm.
Key features:
AI Discovery: AI finds quality videos based on your child's age range, enabled channels, and watch history — approve with one click to add them to the whitelist.
Three modes: Strict / Lenient / Timed
Whitelist: Precise allowlisting by creator ID, BV ID, or bangumi ID
Blacklist: Block specific creators or BV IDs
Channel switches: Block or allow entire categories (anime, movies, live, manga, games, etc.)
Parent Picks: Parents curate videos; kids watch them with one click on Bilibili.
Temporary Unlock: A one-time 6-digit passcode for temporary access in special cases.
Remote Management: Adjust whitelists, picks, and rules from the web dashboard.
Cloud Sync: Automatic sync across devices under the same account.
Watch Stats: Track watch time and progress.
Config Password: Rule changes require an independent password.
Bilingual UI: Switch between Chinese and English inside the extension.
Modes:
Strict: Only whitelisted content is allowed.
Lenient: Only selected channels are blocked.
Timed: Lenient during scheduled hours, strict otherwise.
Pricing:
Core features (whitelist, blacklist, channel blocking, modes, temporary unlock, cloud sync, parent picks) are completely free. AI Discovery includes a free trial (50 reviews); additional reviews are available via subscription. Advanced features such as full statistics reports on the web dashboard require a paid subscription.

What's New in v1.3.2 (2026-09-22)
New Daily Watch Limit: set a per-day minute cap — everything is blocked once exceeded, resets at midnight; temp-unlock time doesn't count.
All time-based rules (timed mode, daily limit, temp unlock) now use server time — changing the device clock can no longer bypass them.
New version announcements: release notes appear on the dashboard and settings page, with one-click store update or manual install; dismissible and reappears on the next release.
Login session extended to 1 year — fixed unexpected logouts after the extension sat idle.
Added a Cancel button on the config-password screen to jump back to the dashboard.
Blocked records now label the "daily watch limit reached" reason.
What's New in v1.3.1 (2026-08-25)
New AI Discovery: AI automatically finds quality videos for your child and adds them to a pending review list. Approve with one click to whitelist; rejecting costs no quota.
One-click reject for pending picks. AI discovery auto-pauses at 30 pending items and automatically resumes when the count drops below 10.
AI task interval reduced from 8 hours to 3 hours — this better fits kids' afternoon/evening schedule (max 2 per day).
Added manual language switch (Chinese/English) in the extension (top-right of settings & dashboard).
Rejecting an approved AI pick now automatically removes the video from the whitelist.
Fixed an issue where whitelist changes could be rolled back by cloud sync for accounts without a config password. Fixed watch-time stats and UI text issues.
What's New in v1.2.1 (2026-08-06)
New Parent Picks: parents add recommended videos; kids see a floating recommendation on Bilibili pages and watch with one click.
New pick watch records: playtime is recorded and shown in the dashboard; watched picks no longer reappear.
Settings page redesigned with a left-side menu: Overview / Rules / Whitelist / Picks / Blacklist / Data Center.
Overview now shows the current mode card with one-tap jump to edit.
Watch stats and blocked records filterable by Today / 7 days / 30 days / All.
Logout requires config password to prevent accidents.
Improved date dropdown styling and recommendation cover loading.
One-time update notes shown in popup and settings after extension updates.
