“How did you build
this timeline?”
Have an answer. Corpus Chronology turns medical records, discovery, and exhibits into a timeline where every event points back to its exact source page. You do the reading. The software keeps the receipts — so the methodology question has a document behind it, not a memory.

The chronology you already deliver, minus the unpaid hours. Page cites are captured while you read instead of typed a second time — and when a new intake pulls you off a case, you come back to exactly where you left it.
Medical Expert Witnesses
Your opinion rests on a timeline that survives cross. Every entry traces to a page in seconds, and no part of it was written, dated, or summarized for you.
Solo Attorneys
Get to the facts of a case without a review platform priced for a firm — or a paralegal to assemble the timeline by hand.
Any format, one project
A production is hundreds of files and thousands of pages — PDFs, scans, faxes, images, whatever the provider happened to send. Point Corpus Chronology at the case folder and all of it becomes a single project you can search, OCR included. The one study that matters is a query away, not a folder-by-folder hunt.
Highlight anything, not just the text
Plenty of what matters was never text — a scene diagram, an X-ray, a photograph, a fax too degraded for OCR. Draw a box around the part that carries the fact and it becomes a highlight like any other: tagged, dated, and cited to its source page. The clipped region travels with it, so the exhibit sits right beside the note you made about it.
Mark events, pick dates
Highlight what happened and tag when it happened. Indexing collects the dates that appear on the page and offers them in the highlight editor, so the single most mistyped field in a chronology gets clicked instead of keyed. Which date matters, and what the event means, stays your call.
See the shape of the treatment
Tagged events drop into a running chronology and onto a timeline you can filter by provider, tag, or event type. Thin stretches look thin, and a provider tag with nothing behind it is a question you would rather ask now than during demand prep.
Export, sourced
Produce a chronology where every entry already carries its source page — ready to drop into the expert report or the case file, not retyped into it.
Don't take the timeline
on faith.
A sample injury case is already open — fourteen records, thirty-seven dated events. Highlight a line, give it a date, and watch it drop into the chronology with its source page attached. The whole thing runs in your browser: no download, no account, nothing uploaded. Close the tab and it's gone.

- Read the records and mark what happened
- Date an event from the dates found on the page
- Watch the chronology build as you confirm each one
Your own case folder, OCR on scans and faxes, region highlights on images and X-rays, and the sourced export at the end of it.
Every event, tied to its
exact source page.
- The columns attorneys ask for. Date, provider, event, source page — filled in as you read, rather than re-keyed from your notes afterward.
- Defensible by construction. Each entry keeps a hard link to its source page, so “where does that come from?” is a click, not a hunt through 456 pages.
- Your judgment, not a guess. Every date and event enters the timeline because you confirmed it against the page — nothing is invented on your behalf.
- The same shape every case. One consistent deliverable instead of a format that drifts from matter to matter.
The tool doesn't testify.
You do.
Courts have sanctioned attorneys and experts over AI-fabricated citations, and a growing number of judges now require generative AI use to be disclosed in filings and expert materials. That exposure lands on the person who signed the report — not on the vendor.
Corpus Chronology has no AI features. No model in the loop, nothing summarized, nothing suggested, no opinion formed on your behalf. Where the app does save you keystrokes — offering the dates it found on a page so you can pick one instead of retyping it — the work is deterministic pattern matching: same page in, same dates out, every time.
Every event is in your chronology because you read the page and decided what it meant. Every event can be walked back to that page while you are on the stand.
- No model. No inference. Nothing to disclose.
- Every entry linked to its source page.
- The same process on every case, so the methodology answer never changes.
The PHI Question
Records stay on your machine — no cloud upload, no third-party processing, except under a policy you set. No processor to vet, no BAA to chase, and no cloud copy of a client’s records to account for.
The Transposed Date
A wrong date in a report is a credibility event, not a typo. Dates found on the page are offered for you to pick, and the page cite comes along on its own — so the timeline reflects the record rather than your transcription of it.
The File You Never Opened
Every document in the case carries a marker until you have opened it, and a file that changes on disk after indexing is flagged. You find out from the app — not from opposing counsel.
Do you use AI to build the chronology?
No. Corpus Chronology has no AI features of any kind. Nothing is summarized, characterized, or suggested, and no part of your chronology was written by a model. If that ever changes, it will arrive as a separate, clearly labeled product — never as a silent addition to the one you already bought and already testified about.
The date pick-list looks like AI. Is it?
It isn’t, and it is worth being able to say why. When a file is indexed, Corpus Chronology collects the dates that literally appear on each page and offers them in the highlight editor so you can pick one rather than retype it. That is pattern matching against text that is already on the page — deterministic, repeatable, and explainable in a sentence. It never proposes a date the page does not contain, and it never decides which date belongs on an event. You do.
Do my records get uploaded anywhere?
No. Indexing, OCR, reading, and export all happen on your machine — nothing leaves it except under a policy you set. There is no account to provision for a case and no third-party processor sitting between you and a client’s medical records.
Can it find gaps in treatment?
It makes them visible. Events appear on a timeline you can filter by provider, tag, or type, so a sparse stretch looks sparse and a provider tag with no events behind it is a question worth asking. What it will not do is read a provider’s name in one note and conclude their records are missing — that inference stays yours, which is also why it holds up when you have to defend it.
How do I know I got to every document?
Each file in the Documents panel carries an indicator until you open it, and the indicator clears once you have. In a large production, what you have not touched yet is visible at a glance instead of something you have to keep track of.
What if a source file changes after I index it?
Corpus Chronology flags it. A file modified on disk after indexing gets a marker under its filename that stays until you re-index, so a swapped or updated production cannot quietly drift out of sync with your chronology.
Why not just use a full review platform?
Most are priced and scoped for firms, not for a solo consultant, expert, or two-person office. Corpus Chronology is single-user, one price, and does one job well. When a case genuinely outgrows it, the same project opens in full Corpus Review with no migration.

Brand new, and yours before it has a mile on it: this build is fresh off the compiler and has not yet had the real-case hours our Mac build has. Everything that makes Chronology what it is came along — no AI, no cloud upload, every event cited to its page — but expect a rough edge or two, and tell us the moment you hit one.
