DrAIStudio is a free studio of AI-assisted tools for researchers, lecturers and students. Every tool runs in the browser, needs no sign-up, and keeps your data on your device unless a tool says otherwise. The numbers below are live counts from the site's own databases.
RefCheck detects retracted papersEvery matched reference is checked against Crossref notices, Retraction Watch and PubMed; journal quartiles (JCR/SJR), AJG and ABDC appear on each card, and you can upload a manuscript to cross-check in-text citations against the list. Open RefCheck →
Exact power analysisPower Simulator now adds G*Power-style exact tests (t, correlation, ANOVA, regression, χ², proportions) with a priori, post hoc, sensitivity and compromise modes — validated against G*Power reference cases. Open →
Bayesian statistics & equivalence testsStatistics Studio reports JZS Bayes factors for t-tests and correlations, TOST equivalence, VIF, Durbin–Watson and HC3 robust errors next to the classical output. Open →
Is the whole specification curve significant?Multiverse Studio adds Simonsohn-style bootstrap tests on the median effect, share of significant specifications and Stouffer z. Open →
Enhanced Standard Analysis for fsQCASmartFSQCA excludes untenable counterfactuals (necessity-contradicting and contradictory simplifying assumptions) and reports the enhanced intermediate solution. Open →
Field life-cycle analysisBiblio Infinity fits a logistic growth model to any corpus: stage, ceiling, inflection year and a five-year forecast. Open →
Upload your documentsExam Generator, Flashcards, AI Tutor, Academic Editor and RefCheck accept PDF, DOCX and TXT uploads, parsed in your browser. Literature Review exports RIS and BibTeX and shows journal quartiles.
The engines are validated against reference implementations and the validation packages are published: SmartSEM 251/251 parity checks against lavaan, semopy and plspm; Statistics Studio 49/49 against SciPy and statsmodels; Biblio Infinity 82/82 against bibliometrix; Power Simulator against G*Power; Multiverse Studio against statsmodels to eight decimals; Event Study to 5.9e-13.
Is DrAIStudio really free?
Yes. Every tool is free, and all but one open instantly without an account. The site is supported by referrals and non-intrusive advertising on informational pages only.
Do I need to create an account?
Almost never. SmartSEM, Statistics Studio, SmartFSQCA, Multiverse Studio, Power Simulator, Biblio Infinity, RefCheck, Literature Review, Journal Finder, CFP Idea Lab, AI Tutor, Quiz Arena, Flashcards, TeachWall and the rest all open and run without signing in. SmartForm is the one exception: it needs a free account because your questionnaires and the responses people submit are stored on the server so you can return to them. Where sign-in appears on other tools it is optional and only saves your work.
Where does my data go?
Analysis tools such as SmartSEM, Statistics Studio, SmartFSQCA, Multiverse Studio, Biblio Infinity and Power Simulator compute entirely in your browser; uploaded files are never sent to our server. AI-assisted tools send only the text you submit to the AI model through our proxy, and nothing is stored.
Can I cite the tools in a paper?
Yes. SmartSEM, SmartFSQCA, Biblio Infinity, FinGraph and Multiverse Studio have citation files and Zenodo or SSRN records; each tool's about page shows the recommended citation.
How do the tools compare with SmartPLS, JASP, G*Power or bibliometrix?
They implement the same published methods, are validated against those reference tools, and add hypothesis-driven workflows, AI interpretation and APA-ready reports — without installation or licences.
Do the tools work offline or on a phone?
Most tools are installable as web apps and work on tablets and laptops; heavy analyses are best run on a laptop. Some features need an internet connection for live databases.
