Pale content may be mistaken for background. No PDF or OCR support.

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.
