What happens if you reach a limit
Daily limits reset at midnight (IST); monthly limits reset on the 1st of each month (IST). If you reach a limit we will show a message — your account and saved work are never deleted. You can wait for the reset, upgrade your plan, or ask us for a Custom plan.
Not allowed
- Automated use: bots, scripts, scraping or bulk API-style calls.
- Sharing one account between several people or reselling access.
- Using the tools to build a competing dataset or service.
- Deliberately sending very large or repeated requests to drain resources.
We may slow down, pause or suspend accounts that break these rules. For serious misuse we may cancel the plan without refund.
Heavy users and teams
Schools, media houses and publishers who need more should choose a Custom plan. Contact support and we will set limits that fit your work.
Changes
We may adjust these limits as AI costs change. Paid members will get at least 7 days' notice by email before any reduction. These terms are part of our Terms of Service.
