Chronos helps law firms turn medical records into a chronology they can check. Upload digital or scanned files, including handwritten notes, and the AI drafts a timeline of documented visits, diagnoses, treatment and billing. Your team verifies each line against its source page before anything is exported.

The question that matters is whether the output stays connected to the record. Chronos pairs page-level citations and confidence signals with an editable workflow for personal injury, mass tort, workers' compensation and other litigation teams.
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.
Upload the records and get a first-draft timeline back in minutes, instead of reading thousands of pages yourself.
Every entry cites the exact source page, so your timeline holds up when opposing counsel challenges it.
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 helps address. Here are the figures that define it.
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 included.
HIPAA's requirements apply to covered entities and business associates. A written BAA is required when a covered entity engages a business associate to perform covered functions or services involving PHI. A law firm or vendor is not automatically subject to HIPAA merely because it handles medical records. Chronos voluntarily makes its BAA available for a firm administrator to review and sign.
HHS BAA guidance →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.

For litigation teams — every feature exists to get a defensible, court-ready timeline out the door faster.
Manual record review is slow, expensive, and easy to get wrong. Chronos answers to both sides of the firm at once.
Hit run and watch the AI medical timeline generator scan the page, light up every clinical fact, and write each one to the chronology — cited.
Example only. The document, patient data, provider names, dates, and billing figures shown above are entirely fictional and used for illustration purposes. No real medical records or patient information is displayed.
Add one PDF or thousands of pages from many providers. Chronos reads scanned, faxed, and digital records alike.
The AI finds every visit, removes duplicates, and puts them in order. You get an editable timeline with a citation on each line.
Filter, add notes, and ask the AI questions. Then export a court-ready PDF or Word file.
Scroll — watch a real chronology assemble. Every entry carries its type and a citation back to the page it came from.
Presented with acute lower-back pain after MVA. Imaging ordered, discharged with muscle relaxants.
Primary diagnosis recorded at ER encounter. Confidence 98%.
L4–L5 disc protrusion with mild nerve-root impingement noted by radiologist.
Course of PT for lumbar radiculopathy. Documented improvement with two reported flare-ups.
Aggregated billed amounts across ER, imaging, and PT linked to each encounter.
Example only. All entries, provider names, dates, diagnoses, and billing amounts shown are fictional and used for illustration purposes only. No real case data is represented.
AI medical chronology software reads a case's medical records and drafts a date-ordered timeline of visits, findings and treatment, with each entry linked to the page it came from. Chronos does that for law firms, and your team checks every line against its source before it is exported. It is an alternative to outsourced record review services, not a replacement for attorney review.
Practical guides on building chronologies, organizing records, HIPAA considerations and where AI fits in record review. If you are choosing software, the buyer's guide is a good place to start.
What a medical chronology is, why attorneys need one, how to organize records, the three major formats, and how AI tools automate the process.
Read the guide →Chronos reads each page, runs OCR where a page is an image, and pulls out the date, provider, facility, diagnoses, procedures and billed amounts for each documented encounter. Entries land in date order with a citation to the page they came from.
That draft is where review starts, not where it ends. Reviewers open the cited page, correct what is wrong and keep open questions visible. The AI organizes the record; it does not give a medical opinion. More on that division of work is in our AI review overview.
If you are new to chronologies, the chronology guide explains formats and manual preparation.
The tools for review, chat and export are on the features page.
Evaluate more than a polished AI summary. Your team needs to know what the supplied records support, what remains uncertain and what changed before the work product leaves the firm.
A dated chronology, a narrative medical summary and provider record retrieval serve different needs. A timeline of uploaded documents does not prove that the complete record set has arrived.
How AI chronology workflows differUse an invented sample with conflicting dates, duplicate pages and an unreadable scan. Check the cited passage, patient identity and each page's disposition—not just whether a draft is produced.
Run a pilot with this checklistVerify dates, medication units, qualifications and billing details against the source. Keep unresolved facts explicit and distinguish what a record states from clinical or legal conclusions.
