Share Storello with writers and editors. Your friend receives Author plan for a week and 40 credits, while you climb the reward ladder and receive 50% of their first purchase in credits.
Milestones are unlocked by verified referrals and never reset.
There is no limit to how many authors you can invite. The milestone ladder currently scales up to 25 verified writers — unlocking the highest tier, Storello Legend (limited to 50 spots).
Rewards are granted for authors who genuinely start drafting in Storello. An invite is verified when your friend writes for at least 15 minutes on three distinct days within a week.
When someone you invited makes their first purchase — whether a subscription or a credit pack — 50% of that value is credited back to your account as AI credits. Credits never expire.
During registration, they can check the "I was invited" box and enter your personal invite code manually within 3 days.
Self-referrals are automatically rejected by qualification verification, which detects matching device signatures and billing profiles.
AI credits remain in your balance permanently and never expire. Plan duration awards grant the specified time (week, month, 6 months), while Storello Legend awards permanent Pro access.
