How it works · Medical records
Redact your medical records, then ask Ai about your health
Cover takes the patient's identity out of the records before Ai sees them. The medical details stay, so Ai can still explain them.
- Visit summaries
- Prescription lists
- Lab results
- Bills and EOBs
How it works
Stop leaking your identity to Ai
Drag the visit summary into Cover, then drag the redacted copy into your Ai chat. It answers with labels where the private details were.
Animation: Visit summary.pdf is dragged into Cover, which replaces each private detail on the page with a label (DOB_1, MED_1, NAME_1). The redacted copy is dragged into an Ai chat with a question, and the Ai answers using the labels.
The visit summary as the Ai receives it, Visit summary-redacted.pdf: Riverside Medical Center After-visit summary 03/28/2026 Patient [NAME_1] Date of birth [DOB_1] Member ID [MED_1] Diagnosis High blood pressure Lisinopril 10 mg daily Atorvastatin 20 mg nightly Ibuprofen As needed Blood pressure today 148/92 Next visit 05/14/2026
Question: Can I take these medications together?
The Ai's answer: Lisinopril and atorvastatin are often taken together. Ask a pharmacist before [NAME_1] adds ibuprofen.
Try it on your own document: drop a PDF into Cover for Web and see what it redacts.
Ask Ai
Plain-English medical answers from Ai, without your identity or your client's
Turn on Tokens and each redaction carries a label like [NAME_1] or [MED_1], the same on every page. The Ai can still tell one record from another and answers with the labels. It works from the labels, not the real details.
What does this diagnosis mean?
[NAME_1]'s summary lists high blood pressure, which means the pressure in the arteries stays higher than it should. Lisinopril is there to lower it. Your doctor can say what your own numbers mean.
What side effects should I watch for?
A dry cough and dizziness when standing up are common with lisinopril, and muscle aches are worth mentioning with atorvastatin. A pharmacist can tell you which ones need a call.
Should I get a second opinion?
The Ai can lay out what [NAME_1]'s records say and the questions worth asking. Whether a second opinion makes sense is a decision to make with a doctor.

What it removes
What Cover removes from your medical records
Cover finds these on its own and redacts them:
- Patient and policyholder names
- Dates of birth
- Member, policy and claim numbers
- Medicare numbers
- Medical-record numbers
- Social Security numbers
- Addresses
- Phone numbers
The medical details stay readable. You check every page in the editor before you save.

Questions
Can Ai explain my records without seeing who I am?
Yes. It needs the medical details, and those stay.
Should I rely on the Ai's answer?
No. Use it to understand your records and prepare questions. Your doctor or pharmacist decides.
Can it read my medical bills too?
Yes. What the plan paid and what's left to pay stay readable.
Is Cover built for HIPAA?
Yes, it is designed to map to HIPAA Safe Harbor (45 CFR 164.514), and nothing is uploaded. That describes how it is built, not an audit or a certification. (Safe Harbor is HIPAA's method of de-identifying health information by removing 18 kinds of identifiers.)
Does it work on scanned records?
Yes, in the Mac app, which reads scanned pages with OCR. In a browser, Cover handles text PDFs. Check handwritten pages in the editor.
