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.
Whimsical is a collaborative visual workspace that combines diagrams, flowcharts, mind maps, wireframes, documents and whiteboards on one infinite canvas, with AI tools that turn a prompt into a structured visual in seconds.

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
Whimsical
Whimsical is a collaborative visual workspace that combines diagrams, flowcharts, mind maps, wireframes, documents and whiteboards on one infinite canvas, with AI tools that turn a prompt into a structured visual in seconds.
Prompt-to-visual AI tools
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
One infinite canvas
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Real-time multiplayer editing
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Wireframing and user flows
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
強み・メリット
+AI generates native, editable Whimsical objects rather than flat images
+Single workspace replaces separate diagramming, whiteboarding, wireframing and docs tools
+Unlimited viewers and guests are free on every plan, including Free
+
Fast, lightweight editor with an excellent template library
+Strong collaboration features — live cursors, object comments, version history
+Serious security posture: SOC 2 Type 2, GDPR/CCPA support, SAML SSO and SCIM on Business
制約・デメリット
–Free plan caps you at 50 board objects and 50 doc blocks per month plus export watermarks
–AI credits are limited per seat and extra credits cost more
–Advanced admin and security features are locked behind the Business tier
–Very large, asset-heavy boards can feel slower than focused single-purpose tools
–No full offline mode; the desktop app still depends on connectivity
