Digital Extensions — Software Studio

Software grounded in
primary sources.

We build tools for people whose work runs on documents — expert witnesses, researchers, compliance teams, case teams — where a claim that cannot be opened to its page carries real cost. Precision, provenance, and control.

Free for macOS and Windows (all installers). No account. Your documents stay on your machine.


Free practice corpus · Keller v. Ashgrove Building Services

1,050 synthetic medical records. Free. Go practice.

Learning chronology work takes a record set you can lawfully open, and new consultants have none. So here is one at full scale: a fictional production built to behave like a real one — faxes, skewed scans, a disc that arrives three weeks late, a handwritten date that changes the story. Fully synthetic, licensed CC BY 4.0, yours to teach with.

Corpus Review

One workspace for the whole set: any format in a single searchable project, highlights that know their page, a chronology that builds as you read, and work product whose every statement can be walked back to its source. Your documents stay on your machine; AI only within the boundary you set.

  • Any format, one project — PDFs, scans, Word files, images, OCR included
  • Highlight anything — a diagram or a scan cites its page like text does
  • A chronology that builds itself — from dated highlights, as you read
  • Export, sourced — every reference carries its page, cited pages attached
Built For
  • Expert witness reports
  • Legal nurse consulting
  • Academic research
  • Compliance & investigations
  • Case teams
  • Journalism

Free

No account, no trial clock. Add-ons for specific workflows will be sold separately; the base stays free.

Corpus Chronology

Now in Corpus Review

Corpus Chronology was a scoped build of Corpus Review, sold to legal nurse consultants. It has been retired as a separate product; everything it did is in Corpus Review, free.
