Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.
RTutor is a web app that turns plain-English requests into R (or Python) code, runs it against your uploaded data and returns results plus a downloadable HTML report. Built on large language models such as GPT-4o, it lets analysts upload a CSV, TSV or Excel file and explore distributions, plots, correlations and EDA reports without writing code.

Any Model, Any Endpoint
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
Retrieval and Search Built In
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Python Tools, Functions and Pipelines
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
Enterprise Controls
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
強み・メリット
+Free and open source with no account needed to install
+Works with local and cloud models through a single interface
+Strong privacy posture: your data and models stay on your infrastructure
よくある質問: Open WebUI 対 RTutor
Open WebUI の月間訪問数は 804,534、RTutor は 2,247 です。トラフィックの推定値はオーディエンスの規模を示すものであり、製品の品質を示すものではありません。
Extensive enterprise features including SSO, RBAC and audit logs
+Large, active community hub of shared prompts, tools and models
制約・デメリット
–Self-hosting requires you to handle servers, updates and backups
–Some enterprise capabilities and support sit behind a paid, quote-based tier
–Feature depth means a learning curve for non-technical administrators
–Local model performance depends heavily on your own hardware
RTutor
RTutor is a web app that turns plain-English requests into R (or Python) code, runs it against your uploaded data and returns results plus a downloadable HTML report. Built on large language models such as GPT-4o, it lets analysts upload a CSV, TSV or Excel file and explore distributions, plots, correlations and EDA reports without writing code.
Natural language to R/Python
Upload CSV, TSV or Excel files and request analyses in plain English; RTutor generates the R or Python code and executes it for you.
Guided analysis tabs
Dedicated tabs for basic, categorical and numerical analysis, summary statistics, tables, correlation and GGpairs plots guide common workflows.
Downloadable EDA reports
Generate multi-section EDA reports and download them as HTML documents in minutes.
Conversational iteration
In a session, previous questions and generated code become context, so you can refine charts and clean data conversationally.
強み・メリット
+Analyze data by describing requests in plain English — no R syntax required
+Runs generated code and returns results, plots and a downloadable HTML report
+Context carries within a session, so you can refine charts and clean data conversationally
+
Guided tabs for EDA, distributions, tables and correlations speed up common tasks
+Available as an R package from GitHub, and Python mode is supported
+Clear privacy stance with automatic deletion of uploaded data after the session
制約・デメリット
–Generated code can be logically wrong even when it runs without error, so results need validation
–Analyzes only traditional statistical data where rows are observations and columns are variables
–Non-profit use is free but commercial use requires a paid license
–By default a small random sample of rows is sent to OpenAI unless you opt out in settings
–Complex or messy datasets are better handled by its sibling tool Datably.ai
