runcell (Jupyter AI agent) is an AI copilot built for notebooks. It understands your current kernel state—variables, DataFrame schemas, imports, outputs—and 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 production‑quality cells (with comments and docstrings) and a clear audit trail of changes.
Whether you’re exploring data, transforming pipelines, or teaching with notebooks, runcell eliminates “search–copy–paste–debug” loops. It nudges work toward best practices (tests, assertions, checkpoints), and documents decisions for future you—or your teammates. Bring your own LLM keys, keep data in your environment, and control exactly what leaves your notebook.
Core capabilities
Natural‑language to code
Drafts new cells or refactors existing ones from plain‑English prompts.
Incorporates notebook context (imports, variables, DataFrame dtypes, shapes) to produce runnable code.
Run, validate, iterate
Executes proposed cells, inspects outputs/exceptions, and auto‑fixes common issues (missing imports, dtype mismatches, off‑by‑one, plotting errors).
Context‑aware 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, missing‑value 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.

Maybe I'll use the remainder of my subscription time to help improve Void. It's already pretty good. https://voideditor.com/. - Source: Hacker News / about 1 month ago
Void is basically the same thing, but open source and better. It's easy to use with any provider API key, even LM Studio for local models. You can use it with free models available from OpenRouter to try it out, but the quality of output is just as dependent on the model as any other solution. https://voideditor.com/. - Source: Hacker News / 4 months ago
Currently editing in Cursor, using agents heavily as I'm a solo dev with limited time. Been exploring running models locally and looking into Zed & Void (https://voideditor.com/). Anyone have opinions on these? Downloading both to try but wondering if the free plan on Zed is doable for full time software engineering, mostly working on next.js sites & native mobile apps in Swift/Kotlin. - Source: Hacker News / 5 months ago
The competition in AI editors is a bit silly at this moment. Everyone and his dog are "building" an AI assisted editor now by duct taping Ollama onto VSCode. I don't like my data being sent to untrusted parties, so I cannot evaluate most of these. On top of that, the things keep evolving as well, and editors that I dismissed a few months ago, are now all of a sudden turning into amazing productivity boosters,... - Source: Hacker News / about 1 year ago
