// Why Chronos

Medical chronology software that keeps every source in view.

When a firm evaluates medical record review software, the key question is whether the output stays connected to the underlying record. Chronos combines medical record analysis with page-level citations, confidence signals, and an editable workflow for personal injury, mass tort, workers' compensation, and other litigation teams. Explore the AI medical chronology software features or compare legal medical record review software and services.

01

Predictable cost per case

One flat credit per case, no matter how many pages. Easy to compare against the open-ended billable-hour cost of doing it by hand.

$400+/hr → 1 flat credit
02

Hours back on every case

Upload the records and get a first-draft timeline back in minutes, instead of reading thousands of pages yourself.

Days of review → minutes
03

A defensible, court-ready chronology

Every entry cites the exact source page, so your timeline holds up when opposing counsel challenges it.

100% of lines cited
// By the numbers

The medical record review challenge — quantified.

A complex personal injury file can span hundreds to thousands of pages of medical documentation across multiple providers. Turning that medical evidence into a defensible medical records chronology software workflow — instead of a manual read-through — is the problem Chronos is built to address. Here are the figures that define it.

40–60 pages / hr

Manual review benchmark

Industry benchmark for manual clinical record review. At that rate, a 1,000-page case file represents 15–25 hours of reading before a single fact is verified — with no source citations built in.

BAA

Required by federal law

HIPAA's Privacy Rule requires a signed BAA before any vendor handles PHI on a law firm's behalf. Chronos includes a BAA with every account — no separate negotiation required.

HHS BAA guidance →
AES-256
+ TLS 1.3

TLS 1.3 + provider-managed AES-256

HIPAA's Security Rule addresses encryption of PHI at rest and in transit. Chronos uses TLS 1.3 in transit and provider-managed AES-256 encryption at rest on Aptible HIPAA-eligible infrastructure.

HIPAA Security Rule →

Sources. Manual review rate modeled from published legal-technology industry benchmarks. BAA requirement: 45 C.F.R. § 164.308 and related HIPAA rules (HHS.gov). Encryption standard: HIPAA Security Rule (HHS.gov). Chronos security details: security overview.

// FAQ

Questions, answered.

A medical chronology is a timeline of a person's medical care. It lists each visit, diagnosis, treatment, and bill in date order. Lawyers use it to see the full story of an injury at a glance.
Chronos is built for law firms that handle injury and medical cases. It helps attorneys, paralegals, and legal teams turn records into clear timelines fast.
Every fact comes with a confidence score and a link to the exact source page. Your team can check it in one click. Chronos is built for review, not blind trust. You stay in control of the final timeline.
Most chronologies are ready in minutes, not days. You upload the records, and the AI builds the first draft right away. Your team then reviews and refines it.
You buy credit packs. One credit covers one case, no matter how many pages. Packs never expire and work across your whole firm. The bigger the pack, the less you pay per case. See the pricing page for current packs.
Yes. Chronos is HIPAA-aligned with a signed BAA on every account. TLS 1.3 encrypts data in transit, and provider-managed AES-256 encrypts it at rest. You also get role-based access, a full audit log, and a signed BAA at no extra cost. Read the full HIPAA compliance details.
You can upload PDFs of any kind — digital, scanned, or faxed — plus common image files. Chronos reads text from image-only records for you. Even low-quality faxes become searchable and citable.
Yes. The timeline is fully editable. You can re-order entries, merge duplicates, hide entries, and add your own notes. Your edits stay in place when you export to PDF or Word.
Yes. The cited chronology can become a demand package, a deposition summary built from uploaded transcripts, or forward-looking damages worksheets — future medical projections, life care plan summaries, and lost income worksheets. See the demand package features.
Yes. Chronos connects to Clio, Filevine, and Litify, so you can push finished chronologies, demand packages, and summaries straight into the matter — no downloading and re-uploading. A firm-level auto-send default means exports land in the matter automatically without anyone pressing "push" each time.
Yes. Chronos extracts ICD-10 diagnosis codes, CPT procedure codes, and HCPCS supply codes onto every chronology entry automatically. The codes are exported with the timeline in PDF, DOCX, and Excel formats and are available in a grouped view, ready for damages models or expert review. See the extraction features.
Yes. Chronos surfaces provider coverage suggestions — flagging providers, facilities, or specialists that appear in the record text but have no uploaded records tracked against them. Your team can accept, dismiss, or restore each suggestion, and every decision is attributed to the team member who made it.
Yes. Any chronology entry supports threaded comment discussions. Team members can @mention colleagues to pull them into a review thread, and open threads are surfaced on the case dashboard. Comments stay within your firm account and are not included in exports.
