The Northwind difference

Built for decisions that need proof.

Most tools ship confident answers. Northwind ships answers your team can defend.

Generic AI

Fast answers, weak traceability.

  • Plausible-sounding text
  • No grounded sources
  • Hard to defend in review

BI tools

Great dashboards, weak messy-document reasoning.

  • Requires clean data warehouses
  • Can't read PDFs or scanned docs
  • Limited narrative context

Northwind

Evidence-backed answers across files, datasets, citations, lineage, and audit trails.

  • Claim-level citations to source rows
  • Lineage from raw input to conclusion
  • Audit-ready review history

How Northwind works

From raw files to decisions you can defend.

Three steps. No glue code, no opaque models.

01

Upload

Bring spreadsheets, PDFs, and documents into Northwind.

02

Analyze

Automatically extract, map, and surface insights.

03

Defend

Every result links back to evidence, citations, and lineage.

Platform

Everything you need to trust conclusions.

Six capabilities that work together — so your team moves fast without losing the paper trail.

Insights

Every insight is generated from your source data — no hallucinations, no orphan claims.

Ask

Natural-language questions answered against your own files and datasets.

Lineage

Trace any number, chart, or conclusion back to the inputs and transformations that produced it.

Audit Trail

Every action, edit, and run is recorded — reviewers never have to reconstruct the work.

Notebooks

Reproducible analysis with live datasets, cell-level runs, and persistent outputs.

Dataset Builder

Turn messy spreadsheets and extracted PDFs into clean, typed datasets.

Data Quality

Type inference, schema validation, and anomaly flags on every input before insights run.

Exports

Ship results to CSV, XLSX, or a shareable link — with lineage and citations intact.

Showing your work

Every answer shows its work.

Northwind links every insight back to the source rows, documents, transformations, and evidence behind it — so reviewers spend time validating, not reconstructing.

  • Claim-level citations
  • Row and document evidence
  • Lineage from input to conclusion
  • Audit-ready review history
The shift

From messy files to trusted answers.

Stop reconciling inputs by hand. Start reviewing conclusions that come with the evidence attached.

Spreadsheets everywhere. PDFs, scattered exports, manual review.

Why Northwind

Why teams choose Northwind.

Six reasons buyers stop evaluating and start shipping reviews.

Not another chatbot

Northwind is a structured workspace — projects, datasets, notebooks, and audit trails, not a prompt box.

Every answer links to evidence

Citations open the exact source rows, documents, and transformations behind each claim.

Works on real messy files

Spreadsheets, PDFs, scanned docs, exports — bring what you actually have, not a sanitized dataset.

Faster than manual review

Automated extraction and mapping replace weeks of reconciliation with minutes of review.

Easier than building internal tooling

No data pipelines, no custom dashboards, no engineering backlog. Upload and go.

Built for teams, not solo prompts

Project-level access, review workflows, and shared context — so decisions scale beyond one person.

Ready on day one

No data pipeline setup, no onboarding engineers, no quarter-long rollout. Upload files, get evidence.

Works without a data warehouse

Bring the files you already have — Northwind structures them on the way in, so you can start reviewing today.

Where Northwind fits

Built for teams that cannot guess.

Evidence-backed workflows your team can adapt — without rebuilding process from scratch.

Problem

Enterprise readiness

Built for enterprise trust.

Controls and guardrails designed for the teams that cannot afford to be wrong.

Scoped permissions so only the right people can view, edit, or approve work.

Audit logs

Every action, run, and edit is recorded for review and reproducibility.

Secure storage

Data stored with encryption in transit and at rest across the platform.

Private workspaces

Project-level isolation keeps teams, clients, and engagements separate.

Human review workflows

Keep a human in the loop on decisions that matter — no silent automation.

Evidence-backed outputs

Every insight carries citations and lineage, so reviewers see the chain of work.

Retention controls

Configurable retention windows for projects and artifacts — keep what you need, drop what you don’t.

Version history

Every notebook, dataset, and insight keeps a replayable history so you can diff answers over time.

FAQ

Questions, answered.

Everything most buyers want to know before starting a pilot.

ChatGPT gives you plausible text from a general model. Northwind gives you grounded answers from your own files — every claim links back to the exact source row, document, or transformation, and the workspace records who reviewed what and when.
Yes. Upload CSVs, XLSX workbooks, PDFs, DOCX files, JSON, images, exports, and URLs to the same project. Northwind extracts, types, and maps them into clean datasets you can join and query together.
Every insight carries citations to the source rows and documents it came from, plus a lineage trail showing every transformation in between. Clicking a citation opens the underlying evidence — no reconstruction required.
Each project is isolated and scoped to its workspace. Data is encrypted in transit and at rest, and role-based access controls govern who can view, edit, or approve work.
Yes. Projects are multi-user with role-based permissions, review workflows, and a shared audit trail, so a team can hand off work without losing context or reconstructing steps.
Northwind is built for finance, operations, legal, compliance, and analytics teams that need defendable conclusions. Enterprise controls include audit logs, human review workflows, private workspaces, and evidence-backed outputs on every answer.
