Your work stays yours
No training on your work
XResearch never trains on your uploads, and the AI providers we route to are set not to train on them.
Yours to remove
Withdraw a paper and it leaves every library it reached.
Reviews stay with the paper
Everyone who can read your paper can read its XReview (cross-review) report. No one else can.
