Runcell

What it does

Runcell is a Jupyter-native AI agent for data analysis, data science, and research. It turns a question into executed notebook work by inspecting the notebook, writing and running Python, reading tables and charts, and fixing errors as the analysis develops. It runs inside JupyterLab on existing .ipynb files.

Runcell is an AI agent that runs inside JupyterLab and works on existing .ipynb notebooks. It writes and executes Python, reads cell outputs such as tables and charts, and keeps context across iterations so the next step builds on the previous result. The site says no API key is required and that the extension installs with pip install runcell. It also says the free Hobby plan includes monthly credits, while paid plans add more credits and access to advanced AI models. The pricing page itself only showed a loading message, so plan details beyond that statement could not be confirmed. The site does not explain how notebook contents are handled or whether data is sent to external services, so that remains unclear. Runcell is built for notebook workflows rather than general file editing, so it does not fit work outside Jupyter.
