Probably Product Launch | product launch video made with ngram

About the video

This product launch video was made with ngram to launch probably, a local-first desktop application that lets anyone at a company ask questions about their data in plain english and receive verified answers with citations and interactive visualizations. the video explains how every figure in a report carries a validated citation back to the source data, and how the system rejects a response rather than risk presenting a hallucinated number. it highlights that all analysis runs locally on the user's machine, so raw data never leaves the device, powered by duckdb, polars, and a custom webgpu charting engine capable of rendering millions of data points. the walkthrough also covers the more than ten supported data sources, including snowflake, bigquery, postgresql, and local csv or parquet files, along with example use cases like exploring churn rates by region or building derived variables. the video closes by directing viewers to download the beta at probably.dev.
