Ask CherAI

Cher’s AI study helper

Your question allowance

…

Every question goes to an AI service that charges Cher for each answer, so there is a cap that keeps CherAI free for everyone:

80 questions a day
Premium accounts have no limit
The site has its own ceiling, so one busy hour cannot lock everybody out

The hourly count resets on the hour. Long answers cost no more than short ones — ask one good question rather than five quick ones.

Answers are written by an AI, so check them against the notes. Pictures are read by Claude, an AI. Please don’t type personal details or include them in pictures.
