GOOD TO KNOW
Clear boundaries.
Useful evidence.
Does it check translation quality?
It checks technical delivery consistency. It does not judge translation accuracy, cultural quality or performance, repair media, or make final delivery approvals. Native-language and creative review remain part of your process.
Do I need an account or a paid plan?
No sign-in or purchase is required for this free preview. Usage is covered by the Free Preview License; the source code remains proprietary.
Can I use it on Windows 7, 8, 10 or macOS?
The currently supported product platform is Windows 11 x64. Other Windows versions, Windows on ARM, macOS and Linux have not been qualified for this release.
What does Unknown mean?
Unknown means there is insufficient evidence to make a particular check. It is not a pass or a confirmed defect. The desktop includes an Unknown summary to help you navigate to the original findings.
Have the rules been calibrated on real deliveries?
The rules have synthetic regression coverage. The planned calibration against authorized real delivery packages is incomplete. Review results manually and tune explicit project expectations for your own approved workflow.
Where do my files and reports go?
Your source files stay in place. Reports are written to a separate local output folder that you select. Local runtime logs can include full file paths; review them before sharing. See the privacy notes.
