Redact Medical Records
To organize progress notes, summarize test results, or prepare a case for a clinical meeting with AI, first remove the personal data from the document: that way you protect its confidentiality.
Your document is not passed to any AI: it does not leave your computer and is not uploaded or stored. The name detector runs inside your browser. You can check it: after the first document, disconnect from the internet and it keeps working.
Options
Document language:
Citations of published works (“(Smith, 2019)” and the reference list) stay as they are. Turn it off for a blind review.
An italic paragraph, in the document’s language, that explains to the AI what the codes in brackets are and asks it not to try to guess the data.
Do you already have a HILO lookup table (from a dataset or another document)? Load it and the same people and data keep their codes.
First time using the anonymizer? To process your document without it leaving your phone, HILO has to download, only once, the dictionaries and files it needs (about 140 MB). We recommend using Wi-Fi. On a phone, the process may take longer than on a computer.
Do not close this tab.
People
ID numbers, phone numbers, and emails
Uncheck what you do not want to replace. The names you see here do not leave your computer.
To review
If you do not review them, they are covered anyway. Review them so you do not cover words that are not data.
Before downloading, look at this
These words were left in the anonymized document and could be people or data. Replace the ones that are.
A medical record without the patient’s data
1. Load it
Load the record, the discharge summary, or the report, in Word or PDF.
2. Review
Check that the patient, relatives, and professionals each have their code.
3. Use it with AI
Work on the clinical content with AI: summarize, organize, compare.
The patient, their family, and their contacts
A medical record has the patient’s name, ID, insurance number, address, and phone numbers, plus those of relatives and professionals. HILO replaces that data with codes; diagnoses, tests, and orders stay as they are, because they are what you want to work on.
A rare case can identify someone even without their name: also think about exact dates, places, and very particular details before sharing.
What gets covered in a medical record
What identifies the patient and the people around them:
- the patient’s and relatives’ names;
- ID and insurance number;
- address, phone numbers, and email;
- names of doctors and other professionals.
Diagnoses, tests, medication, and orders stay: they are the content you want to work on.
What you can ask the AI with the anonymized record
With the full clinical content, the AI can help you:
- put progress notes in date order;
- summarize tests and results;
- prepare a case presentation;
- draft a referral or a report.

The week renews on Monday. Each anonymized document you download counts once per file.
No: HILO covers what identifies a person (names, IDs, contacts, addresses). The clinical content stays, because it is what you need to analyze.
They are people too: they are replaced with codes. If you want to keep one, uncheck it during the review.
Yes, if the PDF has text: you get an editable Word file. Scanned PDFs cannot be read yet.
Yes: it is one of the most common uses. Also check exact dates and unusual details, which can identify the patient even without a name.
ID numbers are always replaced; an insurance number with its own format may show up for review or in the final check.
