Caktus AI is a study platform for students, co-founded by Harrison Leonard and Tao Zhang and launched in August 2022. The company packages more than 25 specialized academic tools, an essay writer with citations, a step-by-step math solver, a code generator, and a flashcard maker, behind a single subscription rather than as separate apps.
Instead of one general chatbot, Caktus AI routes requests to purpose-built tools: dropping in a YouTube link or Ted Talk produces a structured essay outline, while the math solver walks through each step of a solution rather than only returning a final answer. An AI humanizer tool is bundled in to rewrite AI-generated text before submission.
The platform targets high school and college students working through homework, research papers, and coding assignments, and the company states it has been used by 3 million students. There is no open-ended free plan, new users get a single free essay before Caktus AI asks for a subscription, priced at $19.99/month or $99.99 billed yearly ($8.33/month).
