Frequently asked questions
What are this tool’s limitations?
Channel meaning comes from the engine preset you pick; a file cannot say which engine it was packed for.
Are my files uploaded?
Nerulio processes selected files on your device and has no file-upload API. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.
Will my work be saved automatically?
No. Images and editing state stay in this tab; media output can use local temporary storage. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.
