Why check before you post?
A copyright claim after publishing can mean demonetization, removal, or a strike against your channel — even for a few seconds of third-party material. Screening your media first lets you fix problems while they are still cheap to fix: before editing, rendering, and promoting are already done.

UnStrike
AI Copyright Pre-Check Tool
A free tool that combines reverse image search with AI analysis to help you spot potential copyright issues before you upload — so a takedown doesn't catch you after the work is done.
This is not legal advice
UnStrike is a pre-upload screening tool, not a law firm. Results are produced by automated analysis and reverse image search. They are designed to surface obvious risks early — not to deliver a final legal opinion. Copyright law is complex and differs between countries. For commercial projects or disputes, consult a qualified intellectual property lawyer.
What UnStrike does
When you upload a file, two checks run in parallel: a reverse image search that looks for your image or video frames elsewhere on the web, and an AI analysis that inspects the content for logos, artwork, characters, recognizable people, lyrics, and other protected material. The findings are then weighed against the copyright rules of the country you select.
The point is to save your time. A takedown or strike after you have already edited, published, and promoted a post is expensive to fix. UnStrike is the quick check you run first.
How the analysis works
Reverse image search
For images and video frames, UnStrike checks whether your content already appears on other websites. A match is a signal worth investigating — though appearing online does not by itself mean the content is off-limits.
AI visual scan
The analysis examines your image or frames for logos, brand marks, artwork, film and TV stills, trademarked characters, recognizable public figures, and watermarks, and flags anything that warrants a closer look.
Automatic transcript extraction
For audio and video, speech recognition extracts spoken words, which are checked for lyrics, film dialogue, broadcast content, and other protected text.
Country-specific rules
Fair use in the US, fair dealing in the UK and Australia, and Indonesia's moral-rights framework all treat the same content differently. The risk assessment is tailored to the jurisdiction you choose.
What UnStrike cannot do
It cannot give legal certainty
A "Low Risk" score means no obvious red flags were detected — not that the content is legally cleared. Very new or niche material may not be caught.
It cannot detect all music
Audio is analyzed through transcripts and metadata, not audio fingerprinting like Content ID. If your video has background music, verify it separately with a tool such as Shazam or AudD.
It cannot replace a lawyer
If you are publishing commercially, selling merchandise, or facing an actual DMCA dispute, engage a real intellectual property attorney. UnStrike is a first-pass screen, not a verdict.
