Caktus at caktus.ai is a menu of academic tools rather than one open chat. The homepage says to pick from 25+ specialized AI tools — essay writer, math solver, research assistant, flashcard maker, humanizer, and more. You can explore the platform and try several tools for free. Unlimited access to all 25+ AI tools, longer outputs, real academic citations, and document uploads is what the homepage ties to a subscription. It includes annual plan $180 per year and Monthly plan $30 per month, with full access and a 1-day free trial. Cancel anytime before your next charge.

Is Caktus right for you?
Pick Caktus when the task matches a named control: essay type and length, math steps, a citation format, or a flashcard deck from notes. The all-tools directory says to browse all 41 tools available to help with your work. Its FAQ, and the homepage, still say 25+. Both numbers are on official pages and they do not match. Dollar amounts are only on the pricing page, which does not show a free-run quota or a feature the monthly card lacks. The math and research FAQs do describe a smaller free or basic level. Read those beside the 1-day trial rather than treating the trial as the only free path.
A good fit for
A student setting essay type, length, grade level, and APA, MLA, Chicago, or Harvard before export.

Essay type, length, grade, and citations
The essay screen pairs a topic field with a word-count control, an upload, and Write essay. The sample shows 1,000 words. The FAQ lists Argumentative, Expository, Narrative, Descriptive, Analytical, Persuasive, and Compare & Contrast. Caktus can generate essays from 500 words up to 3,000+ words. Grade level is High School, College, or Graduate. Each essay is described with real, verifiable citations and a reference list. We support APA, MLA, Chicago, and Harvard citation styles. You edit in the workspace, then export to Word, PDF, or Markdown. Named uploads are PDFs and Word documents.
Above Calculate, the math page shows Word problem and Equation. You type a problem, paste an equation, or upload a photo of a handwritten or shown problem. The FAQ says Caktus AI covers algebra, calculus (differentiation & integration), statistics, geometry, trigonometry, linear algebra, and discrete math. Results are numbered steps with formulas, substitutions, and plain-English reasons. For many problems the page only describes a graph's shape or key points such as intercepts, maxima, and minima. Full interactive graphing is on our roadmap. You can try the solver for free; unlimited problems need a premium subscription.
Research takes a thesis, a question, or keywords, then lists titles, authors, abstracts, and years from journals, conference proceedings, and preprint repositories. Annotate is supposed to return a citation, a summary, a critical evaluation, and a relevance note. The paper can be saved onto a Caktus document. You can instantly format citations in APA 7, MLA 9, Chicago, Harvard, or Vancouver, then copy the line. Basic searches are available to all users. Unlimited searches, annotations, and exports require a premium subscription.
A deck starts as a subject, pasted notes, or a PDF, Word doc, or text file. Generate anywhere from 5 to 50+ cards per set depending on how much material you provide and the depth of coverage you want. You edit or delete cards, then flip them and mark Got it or Study again. Sets stay on the account. The summarizer takes PDF, DOC, DOCX, or TXT up to 30MB, with brief, standard, or detailed length and paragraph, bullet, or outline format. The homepage humanizer lists Standard, High School, College, and Scholarly presets. The directory names Quizzes, but this page does not document item types.
Starts on the essay tool. Set a documented type, a length from 500 to 3,000+ words, and High School, College, or Graduate. Upload the assignment file if you have a PDF or Word document. Edit sentences and citations in the workspace, then export to Word, PDF, or Markdown. That sequence is suggested, not a paper produced here. The ethics page adds passes the button does not run: start from your own prompt, rewrite in your own words, and submit only work you understand. The essay FAQ says the text is AI content and should be personalized.
Turn notes into cards, a summary, or slides
This suggested loop reuses one lecture file. Build a deck in the 5 to 50+ range and mark cards in study mode. On the summarizer, drop PDF, DOC, DOCX, or TXT within 30MB and choose brief, standard, or detailed output as a paragraph, bullets, or an outline. The FAQ says the model keeps core ideas, definitions, and conclusions. Slides are a further suggested step. The presentation page takes files up to 30MB, shows the style line Modern Pitch Deck Academic Data Driven, and downloads a.pptx with speaker notes. Its FAQ instead names Corporate, Creative, and Minimal. Those lists are not reconciled.
