From messy file to defended answer.
A four-step walkthrough (connect, structure, ask, defend) without leaving this page. Read at your own pace.
Four screens. One end-to-end story.
The tour auto-advances. Each step shows the surface a real user sees: connect, structure, ask, defend.
How the steps fit together.
Each step is a surface in the real product, not a marketing illustration. The walkthrough above is a small mirror of what you would see in the application.
- 01
Connect
Drag in a spreadsheet, paste a CSV, or point at a folder of documents. Northwind treats each one as a first-class source.
- 02
Ingest
Northwind types each column, extracts tables from PDFs, and flags issues that would otherwise hide downstream.
- 03
Ask
Natural-language questions answered over your structured sources. Answers carry the rows they came from.
- 04
Defend
Answers carry source links, a confidence signal, and a trail of what produced them, ready to show a reviewer.
- 05
Reuse
Save the answer, version it, and prepare a clean export your team can hand off without losing the trail.
- 06
Trace
Open any output and follow its lineage back through transforms and joins to the original sources, useful when a reviewer asks where a number came from.
- 07
Review
Hand the answer to a reviewer with the same view you saw, including the citations and the surrounding trail. Reviewer context can be captured alongside the work where supported.
- 08
Refresh
When supported inputs update, related outputs can show staleness signals so you know what to re-run before sharing the same answer again.
