Prompt Lab gives you one focused place to shape a draft, keep the version that works, and compare results when the work needs proof.
Write a Python script that reads a CSV and makes charts. Make it easy to use and handle errors well.
Write a Python 3 script that reads a CSV file and creates charts from it.
Take the CSV path as a command-line argument. Draw one chart per numeric column and save each as a PNG. Print a usage line when run without arguments. Exit with a clear message if the file is missing or has no numeric columns.This transparent sample uses fixed example content. It never reads or sends your text.
One repeatable loop keeps prompt work from disappearing into chat history: improve the instruction, save the useful version, and compare outcomes when quality matters.
The editor keeps prompts and libraries in local browser storage. Before a prompt goes to a provider, Prompt Lab scans it and offers to redact what it finds.

No. Provider usage is separate from Prompt Lab Pro and remains subject to the provider account or local model you choose.
The web editor keeps prompts and libraries in local browser storage. A provider receives content only when you intentionally connect it and run a provider-backed action.
Configured keys stay in browser or extension storage. Hosted web requests pass through Prompt Lab's domain-allowlisted proxy for browser compatibility, but the keys are not persisted server-side.
In Prompt Lab, open Settings → Manage Billing → Manage Purchases to reach Stripe's customer portal, where you can manage or cancel the subscription.
