YouTube, made safe
for your kids.

What WatchBuddy Does

Everything a parent needs.
Nothing a child can bypass.

Six core protections, running silently in the background every time YouTube is open.

🤖

AI Content Filtering

Google Gemini reads video titles, descriptions, and metadata to decide if a video is appropriate — based on your rules.

⏱️

Daily Screen-Time Limits

Set a daily cap. Separate limits for weekdays and weekends. When time is up, YouTube stops — no negotiating.

🔒

PIN-Protected Settings

All parent controls are locked behind a PIN. Kids can't change rules, extend time, or disable the extension.

📋

Custom Rules in Plain English

Type your rules naturally: "Only math, science, and nature videos. Nothing scary. No gaming." WatchBuddy understands.

🚫

Homepage & Search Filtering

Inappropriate videos are hidden from the homepage and search results — not just blocked when clicked.

📊

Activity Dashboard

See exactly what your child watched, what was blocked, and when. A full log, visible only to the parent.


Under the Hood

How WatchBuddy filters content

Every video on YouTube goes through a fast three-step check before your child can watch it.

1
Video metadata is read

When a video page loads, WatchBuddy extracts the title, description, channel name, and category from the page.

2
Gemini AI classifies the content

The metadata is sent to Google Gemini with your parent-defined rules. Gemini returns an ALLOW or BLOCK decision with a reason.

3
WatchBuddy acts on the decision

Allowed videos play normally. Blocked videos are replaced with a clear message. The result is cached so repeated visits are instant.

4
Time is tracked throughout

Every minute on YouTube counts toward the daily limit. When the limit is reached, a full-screen "time's up" screen appears.

Smart Caching
Once a video is classified, WatchBuddy remembers the decision. Revisiting the same video doesn't trigger another AI call — it's instant and uses no quota.

Parent Dashboard

You set the rules.
WatchBuddy enforces them.

First-run setup takes under two minutes. Every setting is adjustable later from the PIN-gated dashboard.

What parents can configure

SettingWhat It Does
Content mode Choose from presets (Education, Kids Entertainment, Family-Friendly) or write fully custom rules in plain language.
Custom rules Natural-language instructions for Gemini: "Only cooking and science. No scary content. No gaming or unboxing."
Daily time limit Set a cap in minutes. Optionally split into separate weekday and weekend limits. Toggle "no limit" for holidays.
Allow / block lists Whitelist specific channels that should always be allowed. Blacklist specific channels that should always be blocked.
YouTube Shorts Block all Shorts entirely, or let them through the same filtering rules as regular videos.
Parent Mode Temporarily suspend all filtering for a set duration — for when a parent is watching with the child. PIN-gated.
Setup Wizard
First install opens a guided wizard: create a PIN, pick a content mode, write rules, and set the time limit. Done in under two minutes. All settings are fully editable later from the dashboard.

Privacy

Transparent about data.
Minimal by design.

WatchBuddy only touches YouTube. Here's exactly what it does and doesn't do with data.

🏠
All settings stored locally

Rules, time config, PIN hash, and activity logs live in Chrome's local storage on your device — never on our servers.

🤖
AI via Google Gemini API

Video titles and descriptions are sent to the Gemini API for classification. WatchBuddy never stores or logs these after the call.

🎯
YouTube-only scope

WatchBuddy only runs on youtube.com. It has no access to any other website or browsing activity.

📵
No GoManzanas servers

We operate no backend. No data is ever sent to GoManzanas. We have zero visibility into usage.

Read the full Privacy Policy for a complete breakdown of every permission and data practice.


Get Started

Install in seconds.

WatchBuddy is a free Chrome extension. No account required, no subscription, no cloud setup.

1
Add WatchBuddy from the Chrome Web Store

Click "Add to Chrome" on the store listing. Chrome will confirm the permissions — WatchBuddy only requests access to YouTube.

2
Run the setup wizard

The wizard opens automatically on first install. Create a PIN, choose a content mode, set the time limit. Takes under 2 minutes.

3
Hand the device to your child

WatchBuddy runs silently. Every YouTube video is checked. Time is tracked. Settings are locked behind your PIN.

Gemini API Key (Optional)
For AI-powered filtering, WatchBuddy uses the Google Gemini API. You can provide your own free API key in the setup wizard, or skip it and use keyword-only filtering. A free Gemini API key is available at aistudio.google.com.
