YYSI account
One account for the whole toolbox. Every account includes three site-wide free AI trials that never reset, for use when AI tools launch. All non-AI tools stay free without an account.
Checking your session…
Email verification and password recovery arrive with our mail service; for now your password is the only sign-in method, so keep it safe. Your trials stay tied to this account — clearing cookies or switching devices does not reset them.
PayPal usage packs: US$4.99 for 100 uses or US$9.99 for 250 uses. Credits do not expire; no subscription or automatic renewal.
Why an account?
AI tools (summarizing, translation and more) need an account so that your three site-wide trials and any purchased usage belong to you across devices. Browser tools like the image and PDF tools work without one.
What we store
Your email, a salted PBKDF2 password hash (never the password itself), session cookies and your trial/usage counters. Sessions expire after 30 days or when you sign out. See the privacy policy.
