<\/picture><\/figure><\/div>\n\n\nCaktus AI is an educational-focused generative AI platform built for students. It is trained only on scholarly sources across the internet.<\/p>\n\n\n\n
Therefore, it is a very suitable AI tool for students<\/a> and educators.<\/p>\n\n\n\n
Caktus AI was founded in 2022 by co-founders Tao Zhang and Harrison Leonard. <\/p>\n\n\n
\n![\"\"](\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2025\/11\/Caktus-AI-Build-for-Students-1024x472.jpg\")
<\/picture><\/figure><\/div>\n\n\nAccording to its App Store listing, over 2.6 million users have downloaded Caktus AI, which is an impressive figure for a platform that\u2019s barely a few years old.<\/p>\n\n\n\n
The platform houses more than 40 specialized tools for different needs a student may face.<\/p>\n\n\n\n
We can roughly divide those tools into aspects: <\/p>\n\n\n\n
- \n
- The writing suite includes an Essay Writer, Paragraph Generator, Personal Statement Builder, Citation Generator (with support for APA, MLA, and Chicago styles<\/a>), and a Text Summarizer. <\/li>\n<\/ol>\n\n\n\n
- \n
- A STEM assistant, which includes problem-solving tools for Physics, Chemistry, Math, and Coding. The Coding Assistant supports all popular programming languages ( Python, Java, C#, and JavaScript).<\/li>\n<\/ol>\n\n\n\n
Caktus AI puts a lot of emphasis on integrity in AI, as stated on the website, \u201cevery feature encourages revision, comprehension, proper citation, and responsible academic use.\u201d <\/p>\n\n\n\n
The Tech Behind Caktus AI <\/h3>\n\n\n\n
At its inception, the founders launched a GPT-3-powered tool for students, however, the founders were quick to reach the conclusion that using off-the\u2010shelf models wasn\u2019t sustainable for their domain because they wanted to prioritize academic rigor.<\/p>\n\n\n\n
By December of that same year, they had partnered with Multimodal to build a proprietary model (named \u201cEguana\u201d) trained on academic data. <\/p>\n\n\n\n
It is currently the world’s best LLM for academic needs.<\/p>\n\n\n\n
A case study reports that approximately 5 billion tokens of academic text were used in training Caktus.<\/p>\n\n\n\n
Key Features of Caktus AI<\/h3>\n\n\n\n
Caktus AI isn\u2019t built for everyone, which is precisely its strength.<\/p>\n\n\n\n
It only targets students and academic writers and has a good list of features for this audience, such as:<\/p>\n\n\n\n
- \n
- It runs on models trained on millions of peer-reviewed papers and scholarly texts<\/li>\n<\/ul>\n\n\n\n
- \n
- The text it produces includes verifiable references, which is a deliberate move to ensure that its generated text comes from real academic sources. It essentially reduces the \u201challucination<\/a>\u201d issue common to general AI writers.<\/li>\n<\/ul>\n\n\n\n
- \n
- It provides step-by-step problem solving for STEM queries<\/li>\n<\/ul>\n\n\n\n
- \n
- It contains a unified workspace for study materials like notes, drafts, citations, and assignments<\/li>\n<\/ul>\n\n\n\n
- \n
- Caktus\u2019s entire system is wired around responsible use of AI <\/li>\n<\/ul>\n\n\n\n
How Much Does Caktus AI Cost?<\/h3>\n\n\n\n
Is Caktus AI free? Unfortunately, Caktus AI does not offer any open-ended free plan.<\/p>\n\n\n\n
There used to be a small free trial for you to test the waters before you commit to a paid plan.<\/p>\n\n\n\n
The trial gave you 5,000 characters of free usage so you could explore how the tool writes, cites, and solves problems. <\/p>\n\n\n\n
After that, you needed a paid plan to keep going. That free trial, however, has been discontinued.<\/p>\n\n\n\n
The pricing information is as follows:<\/p>\n\n\n\n
- \n
- The monthly plan is priced at $19.99\/month, which gives you full access to the platform without long-term commitment. If you get it for a year, you\u2019ll be paying around $240. <\/li>\n<\/ul>\n\n\n\n
- \n
- The annual plan is for $8.33\/month, billed $99.99 per year, which is a more cost-efficient route. It brings the per-month cost down by more than half compared to the monthly plan.<\/li>\n<\/ul>\n\n\n\n
There\u2019s no feature limitation between the two. So, the only real difference is how much you want to save and how long you plan to stick around.<\/p>\n\n\n\n
How Does It Work?<\/h2>\n\n\n\n
You\u2019ll need to create an account or log in before actually getting started with Caktus AI.<\/p>\n\n\n
\n![\"\"](\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2025\/11\/Join-Caktus.jpg\")
<\/picture><\/figure><\/div>\n\n\nOnce you\u2019re in, you land on a clean, focused dashboard that looks like a digital study desk.<\/p>\n\n\n
\n![\"\"](\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2025\/11\/caktus-AI-dashboard-1024x407.jpg\")
<\/picture><\/figure><\/div>\n\n\nThe Essay Writer is the natural place to begin for most users.<\/p>\n\n\n\n
Once you click on it, it requires you to select what you want written out of three options: <\/p>\n\n\n\n
- \n
- An easy essay, the length of which is entirely decided by you, which also allows you to block or include citations<\/li>\n<\/ol>\n\n\n\n
- \n
- A simple essay, which by default includes citations from scholarly sources <\/li>\n<\/ol>\n\n\n\n
- \n
- A detailed essay, which includes citations from academic sources, and multiple other personalization options to control the tone and style of your essay. <\/li>\n<\/ol>\n\n\n\n
It requires you to type in a prompt and pick your citation style (APA, MLA, or Chicago).<\/p>\n\n\n\n
You can also upload your own readings or notes for it to reference, or search Caktus\u2019s internal database for credible sources.<\/p>\n\n\n

<\/picture><\/figure><\/div>\n\n\nHere\u2019s what the dashboard shows when you click on \u2018Easy Essay\u2019: <\/p>\n\n\n
\n![\"\"](\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2025\/11\/easy-essay-dashboard-1024x487.jpg\")
<\/picture><\/figure><\/div>\n\n\nAll you have to do is describe your topic and select how long you want to be. The moment you hit \u2018Generate,\u2019 the AI goes to work building a structured essay. <\/p>\n\n\n\n
When writing a detailed essay, you also get to see some tone customization options:<\/p>\n\n\n

<\/picture><\/figure><\/div>\n\n\nThe same dashboard gives you access to STEM assistants for math, physics, chemistry, etc.<\/p>\n\n\n\n
There are also plenty of other tools, like a summarizer, paragraph generator, AI detector, translator, and interview prep module, all living under the same roof.<\/p>\n\n\n
