## RTutor

RTutor, currently at version 2.00, is a browser-based tool from RTutor LLC (Orditus) that lets you analyze data by describing what you want in plain English. You upload a data file, and RTutor uses large language models to write R — or optionally Python — code, runs it, and shows you the results and the code side by side. The default model is now GPT-4o, and results can be downloaded as an HTML report within minutes.

The workflow is deliberately analyst-friendly. A row of tabs covers basic, categorical and numerical analysis, summaries, tables, correlation and GGpairs plots, plus a dedicated EDA reports tab. Within a session, previous questions and generated code become context for the next request, so you can ask to change a plot color or clean data step by step. A Q&A box lets you ask about the code, the result or an error message, and get guidance on methods or next steps. Uploaded data is loaded automatically into R as a data frame called df; a second file can be added as df2.

Privacy and use terms are spelled out clearly. By default, uploaded data is not sent to the model, though an option exists to include at most five random rows to improve coding quality; column names and data types are sent to guide generation, and uploaded data is deleted when the session ends. The website and source code are free for non-profit organizations only, and commercial use requires a license — businesses can arrange a custom, locally installed version. The developers also point heavier or messier workloads to their sibling platform, Datably.ai.

**Pricing & Plans:** Free for non-profit organizations (website and source code). Commercial use requires a paid license, and RTutor can be customized and locally installed. You can also supply your own OpenAI API key, with roughly $5/month often sufficient.

- **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.
- **Built-in Q&A on code:** Ask about a result or error message and get methods, explanations or a plan for the next step.
- **Python mode & multi-file:** Switch to Python for code generation, or upload a second file as df2 to analyze datasets together.

**Strengths:** 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

**Limitations:** 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

## Z.ai

Z.ai is the consumer-facing assistant from Zhipu AI (Zhipu / Z.ai), the Chinese lab behind the GLM series of large language models. The chat product lives at chat.z.ai and is positioned as a broad, free workspace: you can hold a normal conversation, ask it to write or summarise, and — its most distinctive angle — ask it to generate things. The landing page advertises full-stack app creation, writing, data insight and analytics views, presentation decks and whole web sites, all from a text prompt.

The experience is deliberately low-friction. A guest mode lets you start typing immediately without creating an account, and the interface surfaces a model picker with fast GLM Flash variants for quick generation. When you want history, saved work or higher limits you log in. Behind the chat, the same platform offers API access and developer tooling, so Z.ai serves both as an end-user assistant and as the public face of Zhipu's model lineup for builders.

Because it is free to try and requires no payment details, Z.ai is often compared with ChatGPT as a no-cost alternative — though the comparison is only partial. It is a Chinese-origin platform, so the interface, default language handling and data policies reflect that, and the very strongest GLM models sit behind accounts or paid tiers. For prompt-to-artifact work such as decks, pages and small apps, however, it is a genuinely capable free option.

**Pricing & Plans:** Free to use. Chat and generation modes are available at no cost, and the guest mode needs no account or payment details. Zhipu AI also sells paid access and API plans for higher limits and its strongest GLM models, but the web chat at chat.z.ai is usable for free.

- **AI slide and deck generation:** Describe your topic and Z.ai drafts a slide deck with structured layouts, headings and visual placeholders you can refine with follow-up prompts.
- **Code and app generation:** Paste a brief or a bug report and it will produce code in common languages, and it can scaffold functioning web pages and small full-stack apps.
- **Everyday writing and chat:** Chat, brainstorming, rewriting, translation and summarising all run through the same prompt box, with GLM Flash models keeping responses quick.
- **Web search and research:** Ask a question and it can ground the answer in web sources rather than relying only on its training data, useful for current facts and comparisons.
- **Guest mode with no login:** You can start a conversation without signing in, then create an account later to keep history and unlock higher limits.

**Strengths:** Free to try with a guest mode that needs no account or payment details; Strong at turning prompts into real artifacts: slide decks, web pages and working apps; Built on Zhipu's GLM models with fast Flash variants for quick responses; Covers chat, writing, coding, search and generation in one interface

**Limitations:** Free tier relies on the faster GLM Flash models, with the strongest variants reserved for signed-in or paid tiers; Chinese-origin platform, which some teams rule out for data-handling reasons; Feature quality varies by mode; complex slide decks or full apps usually need follow-up prompting; Account features and some limits require sign-in even though guest chat is available
