Terms of use

Using LeftPen

LeftPen is a free AI editing tool for drafts up to 800 characters. Signed-in members receive 6 edits per Korean calendar day, with a one-hour wait after every 2 accepted edit requests. Each newly registered invited friend adds 2 ongoing daily edits, up to 10 friends and 26 daily edits total. Rewards and midnight resets do not clear an active wait. Examples do not use your allowance; accepted edits count even if cancelled or unsuccessful. Global capacity and concurrent requests may also be limited. Review facts, names, numbers, obligations, and conditions before using the output.

Drafts and results

You must have permission to process your draft. Do not use the service to infringe others’ rights, for unlawful purposes, to attack the service, or to bypass usage limits. You retain your rights to your draft. Accuracy and originality of the output are not guaranteed.
