Using Benford
This guide explains how the web app fits together: workspaces, uploads, analysis runs, charts, and exports. For HTTP API automation (Pro), see the Documentation hub and API quickstart. For plans and limits, see Pricing.
Workspaces
A workspace is where your datasets and analysis runs live. You pick the active workspace from the menu in the app header. Dashboard lists datasets in the current workspace; Uploads and Settings apply to that workspace too.
Roles: Owner and Admin can manage workspace settings and (on Pro) API keys. Member can use analysis and uploads according to your product rules.
Plans: Your account plan applies to workspaces you own. Workspaces you only join as a member follow the owner’s plan. Details are on Pricing.
Creating workspaces: From the dashboard you can create additional workspaces (limits apply on Free).
Workspace settings
Open Settings in the header. Here you can:
- Confidence z-value — Controls how wide the confidence band is around the expected Benford distribution on charts (typical values are around 1.96). New runs use the value saved here; older runs keep the z-value they were computed with.
- API access (Pro) — Create and revoke Bearer API keys for
/api/v1/*. Keys are scoped to this workspace. On Free, the API is not available; you can still read the docs.
Switching workspaces in the header reloads settings and keys for the selected workspace.
Uploads
Uploads accepts CSV on Free workspaces and CSV or XLSX on Pro (with higher size and row limits). The first row must be column headers (names); every row after that is treated as data. The app profiles numeric columns and recommends which columns to analyze.
Free workspaces are limited to a maximum number of datasets per workspace; Pro is unlimited within fair use. Exact numbers are on Pricing.
Processing may finish immediately or return queued while a background worker profiles the file—follow the status link until the dataset is ready or failed.
Datasets and analysis runs
Each upload creates a dataset. When you open a dataset, you can run analysis on the selected numeric columns. That creates an analysis run with status such as queued, running, or completed.
Runs store the tests used (first digit, first-two digits, repetition, and so on) and the z-value in effect for that run so results stay reproducible.
Results: charts, drill-down, exports
Charts compare observed digit frequencies to Benford expectations, with confidence bands where applicable. Drill-down lets you move from a bar (a digit bin) into underlying amounts and row references when your data supports it.
For the First Two Digits chart you can also open First Two Digits Summation Test: a separate drill-down that charts the sum of amounts in each first-two-digit bin (10–99), with an optional % of total view, then the same per-amount and row drill-down as the frequency chart. Use the header control to switch between the two views. Summation is not included in PDF/CSV exports.
AI interpretation (dataset page, after a completed run) can generate a plain-language run summary and an executive draft from the same deterministic results the charts show—optional, server-configured, and subordinate to the numeric output.
Exports produce PDF and CSV reports for a completed run. On Free, exports include plan-appropriate branding; on Pro, exports can be unbranded. Export file retention differs by plan (see Pricing).
