Inkey.ai
A student AI toolkit for essays, math word problems, paraphrasing, grammar, plagiarism checks, AI detection, summaries, and resumes.
About Inkey.ai
Inkey.ai combines more than 30 writing and study tools in one service. It supports essay drafting, math word-problem solving, paraphrasing, grammar checks, plagiarism checks, AI detection, summarization, and resume work. The free Basic plan includes 1,000 words per month and shorter template generations without requiring a credit card. Paid monthly tiers raise the word allowance from 10,000 to 100,000, while the Unlimited plan removes the monthly word cap. Because access is organized around word quotas and template length, students should estimate how often they will draft or revise text before choosing a tier. The service is useful when a learner wants several academic helpers under one account, but its broad toolkit does not remove the need to verify generated writing, math solutions, originality results, or institutional rules before submitting work.
