Which free tier fits
- Writing every day: ExamDay’s 2 a day or UPSC Answer Check’s 5 a month go furthest, on volume alone.
- Long answers on a free tier: Likhit caps free answers at 250 words, so a 15-marker usually fits and an essay does not.
- Checking against real topper answers: only writeupsc does that, with 1 free evaluation; after it, ₹39 for 5.
- Page-based tools: Acme AI counts credits per page, so a three-page answer uses three of its 20 free credits.
