Runcell - Jupyter AI Agent

Pricing is not something to build a pitch on here, so the useful starting point is what Runcell actually does inside a notebook.

Runcell is an AI code agent for Jupyter that reads your code, data and charts, plans the next step of an analysis, and writes the code for it.

It positions itself as a Jupyter alternative to Cursor, so you stay in the notebook instead of moving to a separate editor.

The agent does more than suggest lines.

Runcell can execute cells, run terminal commands, and diagnose errors before applying fixes directly.

That makes it closer to a hands-on assistant than a plain autocomplete add-on, though Runcell also offers context-aware code completion as a Jupyter copilot for the smaller moments.

The fit is clearest for data analysts, researchers and students who spend their day in notebooks, whether cleaning datasets, building models or exploring results.

Since the agent runs cells and commands on its own, review what it does before trusting the output.
