Frequently asked questions

Do text tools upload my content?

Standard text modes run in your browser tab. Your draft stays on the device for local tools — check the privacy badge on each mode.

Can I compare two texts?

Yes — open a diff or compare tool from this hub, paste both sides, and review changes without installing an editor.

Is an account required?

No. Text tools on Tentaco work without sign-up for typical local modes.
