Yes. Houndeye is free, with no account, no ads and no sign-up. It runs in Chrome, Microsoft Edge, and other browsers built on Chrome, such as Brave.

How does it know a video is AI?

Three ways, strongest first. YouTube asks creators to disclose realistic AI video and adds a “Made with AI” note to the description, which Houndeye reads and moves onto the thumbnail. Houndeye users vote, and voters whose past votes matched YouTube's own labels count for more. And it looks for clues, such as a weeks-old channel posting hundreds of videos or a title that says it was made with Sora. One clue on its own never earns a badge.

Will it catch every AI video?

No, and nothing can today. Plenty of AI video is never labelled, and good fakes fool people. Houndeye shows you what is known about a video and how sure it is, and it gets better as more people vote. When it isn't sure, it stays quiet rather than guess.

Does it work on Shorts?

Yes. Shorts in your feed and in search get the same badges, and the Shorts player shows the warning and the vote buttons.

What does Houndeye know about me?

Very little, on purpose. There is no account and no name or email. When you vote, Houndeye receives the video, your vote and an anonymous random number. It never receives your watch history. The privacy policy lists every single thing that is sent.

I made a video and Houndeye flagged it. What now?

Use the appeal form. Tell us which video and why it's real, and a person will look at it. If the appeal is upheld, the badge comes off for everyone.

Hounds are bred to notice what everyone else walks past. Ours carries a magnifying glass, because every badge should come with its evidence.

Privacy policy

Last updated October 3, 2026. Applies to the Houndeye browser extension and to houndeye.app.

Houndeye is made by Mako Logics LLC (“we”). It is built to need as little about you as possible: there is no account, and we never learn your name, your email address or your Google account from the extension. This page lists everything the extension and this website collect. If something isn't on this page, we don't collect it.

The short version

We receive your votes, and the video and channel they are about.
If you opt in, we receive the videos where you came across YouTube's own “Made with AI” label.
Both come with an anonymous random number, so one person gets one vote. We store only a scrambled version of it.
We never receive your watch history, your searches, or any video, audio or screenshot.
We don't sell or share personal information, and there are no ads or trackers in the extension.

What stays on your computer

The extension keeps these in your browser's own storage. They are not sent to us.

What	Why	How long
Your settings and trusted channels	To remember your choices. If your browser syncs settings, your browser's maker syncs these between your own devices; we never see them.	Until you change or clear them
Your anonymous Houndeye number	A random 64-character number created when you install. It identifies your votes without identifying you.	Until you uninstall or press “Forget everything”
Results of label checks	For each video Houndeye checked: the video ID, whether YouTube labels it as AI, and its channel. Saves checking twice.	14 days, at most 20,000 videos
Channel ages	A channel's join date and video count, read from its YouTube page, for the “new channel, many uploads” clue.	14 days
Your own votes	So the vote buttons show what you picked.	Your latest 5,000 votes
The shared flag list	A list of videos and channels the Houndeye community has flagged, downloaded every few hours, so thumbnails can be checked on your computer instead of by asking us about each one.	Replaced at each download

What the extension asks YouTube

To find YouTube's “Made with AI” label before you click, Houndeye asks YouTube for the details of videos on your screen, and for a channel's “About” page on the video you're watching. It does this from the YouTube page, the same way YouTube's own page does. These requests go between your browser and YouTube, under YouTube's own privacy policy. Houndeye's servers are not involved and don't see them. You can limit or turn this off in the extension's settings. The extension caps it at 40 videos per page and 800 a day.

What the extension sends to Houndeye

All of it goes to api.houndeye.app, over an encrypted connection.

When	What is sent	Why
Every few hours	A request to download the shared flag list. Nothing about you.	To badge flagged videos.
On a video page	The first 4 characters of a scrambled (SHA-256) version of the video's ID. Thousands of videos share any 4 characters, so this doesn't tell us which video you're on. We send back every match and your browser picks out the right one.	To show the current vote count.
When you vote	The video's ID, its channel, your vote (Real, AI or Not sure) and your anonymous number.	To count your vote.
Only if you opted in	When Houndeye finds YouTube's “Made with AI” label on a video: that video's ID, its channel and your anonymous number. Videos without the label are never reported.	So other people see the badge sooner.

When you vote or share a label, we store a scrambled (SHA-256) version of your anonymous number, never the number itself. To stop vote-stuffing, we also store a keyed, one-way scrambled form of your network (the first part of your IP address), never the IP address itself. We use it to limit how many votes and new installs come from one network.

Like any website, our hosting provider, Cloudflare, sees your IP address when your browser connects, in order to deliver the request. Our request logs, which can include it, are kept for up to 7 days to fix problems and are not used for anything else.

What we never collect

Your watch history, search history, or the list of videos you browse.
Any video, audio, image or screenshot.
Your name, email address, Google or YouTube account, or contacts.
Anything from websites other than YouTube. The extension only runs on youtube.com.

How votes are used

Votes are combined into a public tally per video and per channel, which every Houndeye user can see. A vote can't be traced back to a person by anyone, including us. Votes and confirmed labels are kept for as long as Houndeye runs, because they are the community's shared record. They may also be used, without your anonymous number, to improve Houndeye's own AI-video detection.

Your choices

Sharing labels is off unless you turn it on, on the welcome page or in Settings.
Checking labels before you click can be limited to videos you point at, or turned off.
“Forget everything” in Settings deletes everything stored on your computer and gives you a new anonymous number. Votes already sent stay counted but can no longer be linked to you.
To delete votes you already sent, open Settings, copy the code shown under “Your data”, and email it to support@houndeye.app. That code is the scrambled number we store, so it lets us find your votes without knowing who you are.
Uninstalling removes everything the extension stored on your computer.

This website

houndeye.app uses Vercel Web Analytics and Speed Insights to count page views and measure page speed. They don't use cookies and don't build a profile of you. If you send an appeal, we receive what you type (your email address, the video or channel, and your message), and Cloudflare Turnstile checks that you're a person. We use appeals only to review the badge and reply to you, keep them for up to two years, and delete them sooner on request.

Who processes data for us

Cloudflare: runs api.houndeye.app, Turnstile and our email forwarding.
Supabase: hosts the database of votes and labels, in the United States.
Vercel: hosts this website and its analytics.

We don't sell personal information, share it for advertising, or use it for anything except running Houndeye.

Children

Houndeye is not directed at children under 13, and we don't knowingly collect personal information from them.

California residents

Under the CCPA you can ask what we hold about you and ask us to delete it, and we will not treat you differently for asking. We do not sell or share personal information. Email support@houndeye.app with the code from Settings to make a request.

Changes

If we change what Houndeye collects, we'll update this page and its date before the change ships. Anything new that involves your data, such as scanning the video itself, will be opt-in.
