A Mac app for early case assessment, review and production
Review and produce discovery documents without losing control of your client’s data.
Drop in a folder of client files, search everything, code each document and produce a Concordance-compatible load file with Bates numbers. All of it happens on your Mac, and no cloud service, vendor or outside server ever holds a copy.

Your client’s files never leave your Mac
No cloud, no vendor, no one else’s server.
There is no cloud behind Discovery Triage. We never have your files, so we have nothing to lose, leak or hand over.
Nothing to upload
Documents are copied into a project folder on your Mac and stay there. No service provider holds a copy, so there is no vendor to vet and no outside server to be breached.
No networking code
No accounts, sync, analytics, telemetry or update checks. The app does its work without an internet connection.
AI that stays on the Mac
AI review uses Apple Intelligence’s on-device model. Document text is never sent to a server, ours or anyone else’s.
Evidence cannot phone home
HTML, XML and SVG documents are shown with remote content blocked and JavaScript off, so opening one never reaches out to the internet.
Projects live in the app’s private folder on your Mac, or a location you choose, and the app warns you if that disk is not encrypted. Read the full privacy policy.
Ingest, review, produce
One app for the whole path from a folder of files to a production set.
- 01
Ingest
Documents are copied into a project folder on your Mac; originals are never modified. Text is extracted, scanned PDFs and images are OCR'd, and every file is fingerprinted with MD5 and SHA-256 hashes. Exact duplicates are found across all your sources by those hashes and marked, never deleted; a production can leave them out so each file goes once. Email families, including messages inside PST files, stay together. Text messages from a phone come in too, one document per conversation per day.
- 02
Review
Full-text search with ranked results and highlighting. Code each document Responsive, Not Responsive or Needs Review and flag privilege from the keyboard. Tags, saved searches, document sets and a privilege log.
- 03
Produce
Concordance .DAT and Opticon .OPT load files, Bates numbering, native files, text files and Bates-stamped page images (one JPEG or PDF per page). A pre-production summary shows what will and will not be produced before anything is written.
Ask your documents
Search by meaning, ask a question of the whole case, and build a timeline, all on your Mac with Apple Intelligence. Every answer links to the passage it came from. Version 1.1 is in Apple’s review now and arrives as a free update.

Built so mistakes are hard to make
AI suggests, you decide
Describe your case and what you are looking for, and Apple Intelligence suggests responsive and possibly privileged documents. It runs on-device, so document text is never sent to a server. AI suggestions are never final: by default only documents you coded Responsive are produced.
Privilege holds
A document coded privileged is never produced by default. A Responsive document the AI flagged as possibly privileged is held back until you answer the privilege question or deliberately override the hold.
Tamper-evident audit log
Coding, tags, AI runs, productions, exports and backups are recorded in a hash-chained log you can verify inside the app and export as CSV or JSON. It shows whether the record was altered; it cannot prevent it.
Backups
One-step project backup and restore with a checksum manifest, plus automatic snapshots before risky operations such as imports and productions.
What it reads
- Documents
- PDF (with OCR for scans), Word, PowerPoint, Excel and RTF
- PST and OST (Unicode format), MSG, EML, mbox and winmail.dat
- Text messages
- iPhone Messages (from a Finder backup or a Mac), Android SMS Backup & Restore, and WhatsApp chat exports. One document per conversation per day, with photos attached.
- Images
- PNG, JPEG, TIFF, GIF, BMP and HEIC, with OCR
- Archives
- ZIP, TAR and TAR.GZ. Extract 7z and RAR archives first.
- Audio and video
- Indexed by metadata only. For transcription, see the companion app Soundproof Legal.
What it needs
- To run the app
- A Mac running macOS 26 or later.
- For AI review
- A Mac with Apple silicon that supports Apple Intelligence, with Apple Intelligence turned on in System Settings and a language and region it supports.
- Without it
- Everything except AI review still works: import, extraction, OCR, search, manual coding, the privilege log and production.
