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.

Runcell'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.
