runcell (Jupyter AI agent) is an AI copilot built for notebooks. It understands your current kernel stateโvariables, DataFrame schemas, imports, outputsโand proposes the next best cell to move your work forward. With one command, it can draft code, execute it safely, validate the output, and automatically refine on errors. You get productionโquality cells (with comments and docstrings) and a clear audit trail of changes.
Whether youโre exploring data, transforming pipelines, or teaching with notebooks, runcell eliminates โsearchโcopyโpasteโdebugโ loops. It nudges work toward best practices (tests, assertions, checkpoints), and documents decisions for future youโor your teammates. Bring your own LLM keys, keep data in your environment, and control exactly what leaves your notebook.
Core capabilities
Naturalโlanguage to code
Drafts new cells or refactors existing ones from plainโEnglish prompts.
Incorporates notebook context (imports, variables, DataFrame dtypes, shapes) to produce runnable code.
Run, validate, iterate
Executes proposed cells, inspects outputs/exceptions, and autoโfixes common issues (missing imports, dtype mismatches, offโbyโone, plotting errors).
Contextโaware assistance
Explain cell: summarizes what a cell does and why.
Suggest next step: proposes analysis steps, visualizations, or checks based on your artifacts.
Inline docs: inserts comments, docstrings, and markdown rationale.
Environment & reproducibility
Detects missing packages and (optionally) generates a safe install cell; can export requirements.txt or environment.yml.
Data & visualization helpers
Quick EDA: profiling, missingโvalue maps, summary stats.
Transformations: joins, groupby, window ops, feature engineering.
Visuals: histograms, pairplots, line/bar charts, residual plots, interactive charts (e.g., Plotly).
Works smoothly with pandas, numpy, polars, matplotlib/plotly, and visualization helpers like pygwalker.
VS Code
RuncellRuncell's answer:
Runcell is the AI Agent designed for Jupyter users. It is not a simple chatbot, but an agent that can take control of your jupyter and work for you.
Runcell's answer:
Comparing with Code agent, like cursor, claude code, which are designed for software enginner, those agent does not understand data, visualization, very well. And when they coding, they directly generate all code without considering how the data distribute, what is the result of previous cells execution which are important for data science.

Visual Studio Code, a code editor created by Microsoft, was first introduced on April 29, 2015, at the Build conference. - Source: dev.to / 12 days ago
The step up from there is an editor with a built-in agent like Cursor, Google Antigravity, Windsurf, or VS Code with a coding extension. These are code editors with an AI agent living inside them, and the difference is the responsible party for getting things from place to place. Instead of the software creator shuttling code between windows, the AI agent edits the project files directly and runs the GitHub and... - Source: dev.to / 27 days ago
For IDE-heavy teams, BYOK (bring your own key) can be interesting, no matter whether you live in WebStorm or VS Code. On the JetBrains side, the JetBrains AI plans and Junie BYOK docs allow it, and most VS Code AI extensions offer the same idea: keep the IDE, connect provider keys, pay the provider. - Source: dev.to / about 2 months ago
Option 1: Raw editing in IDE. You open the .md file in VS Code or whatever you use. Syntax highlighting shows you the structure. Maybe you toggle a preview pane. This works for quick edits but becomes painful for anything involving tables, diagrams, or complex formatting. - Source: dev.to / about 2 months ago
You'll need Python 3.8+ and pip for the quickstart, with venv recommended for isolation. Install the requests library for HTTP calls. VS Code with the Python extension works well as an editor, though PyCharm or Sublime Text work equally well. You'll also need a free Foxit developer account. - Source: dev.to / about 2 months ago
