Each tool explains the rule behind its answer, so a correction teaches you something instead of just fixing one sentence.
Limits are simple and the same for everyone: five grammar checks and ten timed-quiz starts per day, resetting at midnight UTC. Text you submit to an AI tool is processed by an AI provider, so avoid sensitive personal information.
