Best AI Video Detectors, Compared
Short answer
For a free check of one suspicious clip with no account, AI Video Detector is the pick: it needs no signup, reads the file in your browser for Content Credentials and AI labels, and shows still frames to inspect. For a frame-by-frame AI score on clips up to 2 minutes, DeepfakeDetector.ai's free account gives 50 scans a month.
The other four tools win narrower jobs. Hive Detect suits checking while you browse. isFake.ai covers text, images, audio and video under one free plan. DetectVideo AI takes the longest files, on a paid pack. aivideodetector.com allows 10 free analyses an hour. Every value below comes from each tool's own pages, checked on 8 November 2026.

Tool by tool
Each section uses the same order: what the free tier gives, the limits, and the one thing it is best at.
AI Video Detector
The free checker on the AI Video Detector home page reads the clip's file in your browser, so the video is not uploaded. It looks for Content Credentials under the C2PA specification, AI labels that use the IPTC digital source type codes, and AI tool names in the file's metadata, and it shows still frames from across the clip for you to inspect. The result is one of four verdicts: AI generated, Likely AI, Likely real, or No AI signs found. It is free with no signup.
- Best for
- Reading a clip's AI labels without uploading it
- Free tier
- Yes
- Free clip or file limit
- No set limit; the file is read in your browser
- Signup required
- No
- Shows frame-level evidence
- Still frames to inspect, no frame scores
- Other media checked
- None, video only
- Source page, date checked
- aivideodetector.io, 8 November 2026
Main limitation it reads labels, and many AI clips carry none, especially after re-uploads. It gives no frame scores, and it checks video only. "No AI signs found" is not proof that a clip is real. It is one signal, and you still need the source and the context.
DeepfakeDetector.ai
DeepfakeDetector.ai offers a free account with 50 scans a month and clips up to 2 minutes. It also checks images and voice, which makes it the better pick when the suspicious thing is a voice note or a photo rather than a video.
- Best for
- Clips up to 2 minutes, plus images and voice
- Free tier
- Yes, 50 scans a month
- Free clip or file limit
- Up to 2 minutes per clip
- Signup required
- Yes, a free account
- Shows frame-level evidence
- Yes, video frame scores
- Other media checked
- Images, voice
- Source page, date checked
- deepfakedetector.ai/pricing, 8 November 2026
Main limitation you need to create an account before the first scan.
Hive Detect
Hive's free demo sits at hivedetect.ai. Hive's AI-generated content detection page describes frame-by-frame detection with probability scores for images, video and audio. The free Hive AI Detector extension lets you right-click media on a page, also covers text, and its listing says no login is needed.
- Best for
- Checking media while you browse
- Free tier
- Yes, a free demo and a free Chrome extension
- Free clip or file limit
- Not stated
- Signup required
- No login for the Chrome extension; not stated for the web demo
- Shows frame-level evidence
- Yes, frame by frame
- Other media checked
- Images, audio; text in the extension
- Source page, date checked
- hivedetect.ai, Hive blog, Chrome Web Store, 8 November 2026
Main limitation Hive's pages do not state a free clip or file limit for the web demo. The product is aimed mainly at platforms and trust and safety teams, so the consumer tools are the side door.
isFake.ai
isFake.ai's video page lists a free limit of 30 seconds and 15 MB per clip, in MP4, MOV, WMV, AVI or WebM. It says results highlight flagged frames with confidence scores. Its pricing page describes the free plan as basic daily checks across text, images, audio and video, with paid plans from $3.99 for a one-time check.
- Best for
- Text, images, audio and video in one place
- Free tier
- Yes, basic daily checks
- Free clip or file limit
- 30 seconds and 15 MB
- Signup required
- Not stated
- Shows frame-level evidence
- Yes, flagged frames with confidence scores
- Other media checked
- Text, images, audio
- Source page, date checked
- isfake.ai/video and /pricing, 8 November 2026
Main limitation the 30 second cap is tight for anything longer than a short social clip.
DetectVideo AI
DetectVideo AI offers a complimentary file check, with the current limits shown inside the scanner rather than on the page. It describes a frame review step and a report of flagged moments. Its pricing page lists one-time packs from €9 for 20 analyses, with files up to 500 MB and videos up to 30 minutes. Pasting a public link needs a paid pack.
- Best for
- Long files on a paid pack
- Free tier
- Yes, complimentary file checks
- Free clip or file limit
- Not stated (the live scanner shows it)
- Signup required
- Not stated
- Shows frame-level evidence

- Other media checked
- None, video only
- Source page, date checked
- detectvideo.ai and /pricing, 8 November 2026
Main limitation the free limits are not written down anywhere you can read before you upload.
aivideodetector.com
A different site from this one, despite the similar name. aivideodetector.com accepts MP4, MOV, AVI and WebM files up to 500 MB and says no registration is needed for basic detection. Its pricing page lists a free plan of 10 analyses per hour.
- Best for
- Several checks in a row
- Free tier
- Yes, 10 analyses an hour
- Free clip or file limit
- 500 MB per file
- Signup required
- No, for basic detection
- Shows frame-level evidence

- Other media checked
- None, video only
- Source page, date checked
- aivideodetector.com and /pricing, 8 November 2026
Main limitation its pages describe a confidence score, but do not say whether you see which frames drove it.
How we compared
This is a comparison of documented features. Every value in the table comes from the tool's own website, read on 8 November 2026, after confirming each tool's official domain. Where a tool's pages did not give a value, the cell says "not stated" rather than a guess.
The seven fields are the ones that decide which tool you can use right now: whether there is a free tier, how long a clip it takes, whether you must sign up, whether it shows evidence at frame level, and what else it checks. Nothing here measures how often any tool is right. No accuracy figures appear for any tool, including the ones the tools publish about themselves, because a vendor's own number is not comparable with another vendor's.
Known weak spots of this method: free limits change without notice, some tools show their limits only inside the uploader, and a feature listed on a page is not the same as a feature that works well on your clip.
Caveats
No AI video detector result should be the only evidence that a clip is fake or real.
Free tiers move. A limit that was 30 seconds on 8 November 2026 may be different next month, so check the tool's own page before you rely on it. Re-uploads and screen recordings lose detail, which affects every tool in the table. A clean result on a compressed copy tells you less than a result on the original file.
If you want to judge a clip yourself before or after running a tool, the nine checks for telling if a video is AI cover what to look for. If the worry is a real person's face on a fake clip, start with the free deepfake video detector. For clips that may carry Google's invisible watermark, SynthID explained covers what that mark can and cannot show.
For a quick check without an account, the AI video detector on this site is the starting point; the comparison above is maintained by Tessa Ostrowski.
