Is Kaption safe to use?

It captures a small region of your screen, reads the text locally, matches the line against a dialogue database, and shows the translation as a desktop overlay.

That overlay is separate from the game. You close Kaption and the game has nothing to undo.

It does not inject code, hook the game process, patch files, read memory, automate gameplay, or change your account.

If your antivirus flags Kaption, look at what kind of flag it is. Named malware families (Trojan.Generic.XYZ, Ransomware.ABC, etc.) are signature-based — they match known bad code. Heuristic or machine-learning flags (anything with ".ml.score", ".Heur", ".Suspicious") are predictions: the file has features the model has seen in bad files before.

Every release gets scanned on VirusTotal. Microsoft Defender and the other ~70 engines report clean. One ML-based engine (Trapmine) sometimes returns "Malicious.moderate.ml.score" — note the ".ml.score" suffix. That is a heuristic prediction, not a match against known malware.

The Setup.exe is not code-signed during open beta, so Windows SmartScreen shows "Microsoft Defender SmartScreen prevented an unrecognized app from starting". Click "More info" → "Run anyway" to continue.

This is the standard Windows UX for any unsigned indie app. Signing with an Authenticode certificate is planned once the beta graduates — that also clears the last ML-based heuristic flags on most antivirus engines.

Download Setup.exe, then right-click → Properties → Digital Signatures (blank during beta — expected) OR compute the SHA-256 hash with PowerShell: Get-FileHash .\Kaption-stable-Setup.exe. The hash must match the one published on the VirusTotal scan linked below.

If the hashes differ, something modified the file between our server and your disk. Email contact@kaption.one and do not run it.
