Sentence case converter that keeps acronyms

Paste text typed in ALL CAPS and press Sentence case. Each sentence starts with a capital, the rest goes lowercase, and acronyms like CHF, HTN, and ADLs stay in capitals.

Your text stays in this browser tab. WriteKeys never uploads or saves it. How it works

My tools

Make your own buttons. A tool runs its steps in order, like removing every em dash and every $ sign, replacing & with “and”, or inserting “Dx: ” before CHF.

    My words to replace

    When WriteKeys finds a word on the left, it changes it to the word on the right. Useful for words a PDF misreads the same way every time, like ESRO for ESRD.

    Whole words only. Lowercase finds any capitals (esro finds ESRO and Esro). A word typed with capitals matches exactly.

      No words yet. Add one above.

      Autocomplete

      As you type, WriteKeys suggests words and phrases from this list. Press Tab to use the suggestion, or tap it on a phone. The spell check counts the words on this list as spelled right.

      Press Enter to add. A comma stays part of the phrase. To add several at once, paste a list with one on each line, or press Shift+Enter between them. Suggestions start after you type 2 letters. Tip: select a word in your text before opening this window and it is ready to add.

        No words yet. Add the names, programs, and phrases you type most.

        Saved in this browser only, and still here after you close it. Never sent anywhere. Don't add patient names or anything else that identifies a person.

        Ignored words

        The spell check doesn't mark these words. A word goes on this list when you choose Always ignore in the spell check, or when you add it here. Delete a word to have it marked again.

        Separate several words with spaces. Capitals don't matter: lasix also covers Lasix.

          Templates

          Save text you start notes with, like a visit note outline, and put it in the text box with one click. It goes where your cursor is, or fills the box when it is empty. The first 3 on this list also have a button under the text box.

            No templates yet. Type or paste an outline in the text box, then press + New template to save it.

            Before and after

            The same ALL CAPS text, converted with Keep acronyms on and then off:

            Before
            CLIENT HAS A HISTORY OF CHF, HTN AND COPD. NEEDS HELP WITH ADLS.
FOLLOW UP WITH PCP ON MONDAY.
            After: Keep acronyms on
            Client has a history of CHF, HTN and COPD. Needs help with ADLs.
Follow up with PCP on Monday.
            Before
            CLIENT HAS A HISTORY OF CHF, HTN AND COPD. NEEDS HELP WITH ADLS.
FOLLOW UP WITH PCP ON MONDAY.
            After: Keep acronyms off
            Client has a history of chf, htn and copd. Needs help with adls.
Follow up with pcp on monday.

            With the list off you get what most converters produce: chf, copd, adls, and pcp, each one a fix you would make by hand.

            How sentence case is decided

            • The first word of the text, and the first word after a period, question mark, or exclamation mark, gets a capital.
            • In ALL CAPS text, each new line also starts with a capital, so lists and headings come out right. In ordinary text, a line that continues a sentence stays lowercase.
            • After a colon, the next word gets a capital if it had one before: PLAN: FOLLOW UP becomes Plan: Follow up.
            • A period after Dr., Mr., Mrs., vs., approx., or initials like i.e. doesn't start a new sentence.
            • The word I stays a capital, and so do I'm, I'll, I've, and I'd.

            Which acronyms are kept

            332 terms are on the list. A sample:

            Conditions
            CHF, HTN, CAD, COPD, CKD, ESRD, CVA, TIA, GERD, UTI, DVT, PTSD, ADHD, TBI, OSA, SUD
            Care settings and roles
            ICU, ER, ED, SNF, ALF, LTC, IRF, PCP, RN, LPN, CNA, NP, LCSW, MSW, CHW, HHA
            Benefits and programs
            SSI, SSDI, SNAP, TANF, WIC, HUD, LIHEAP, FMLA, HCBS, IHSS, Medicare, Medicaid
            Charting
            Hx, Dx, Tx, Rx, DOB, MRN, PRN, BID, TID, NPO, DNR, POA, POLST, ADLs, IADLs
            Tests and vitals
            BP, HR, SpO2, BMI, CBC, BMP, A1C, HbA1c, eGFR, INR, EKG, MRI, CT

            Plurals work too: ADLS becomes ADLs and NSAIDS becomes NSAIDs. Months and weekdays keep their capital letter, except May, which is also an ordinary word. A few terms, such as CAD, SOB, ED, and SNAP, are kept only when they are already in capitals, so “she began to sob” is left alone.

            Words that are already in capitals

            When text mixes capitals and small letters, WriteKeys assumes a short word in capitals is an acronym it hasn't heard of, such as an agency's or a health plan's initials, and leaves it alone. Names with a capital in the middle, like McDonald, keep it too. A run of words in capitals, like FOLLOW UP IN TWO WEEKS, reads as shouting and gets converted.

            Before
            Client is stable. Spoke with the HHSA worker at McDonald clinic. FOLLOW UP IN TWO WEEKS.
            After: Sentence case
            Client is stable. Spoke with the HHSA worker at McDonald clinic. Follow up in two weeks.

            What it gets wrong

            Sentence case works from rules, not understanding. Check these by eye:

            • Names in ALL CAPS. In text that is all capitals, a name looks like any other word, so MARIA LOPEZ becomes Maria lopez. Select the name and press Title Case.
            • Abbreviations that are also words. PT (patient, or physical therapy?), OR, MS, and AIDS (as in hearing aids) are left off the list, because turning an ordinary word into capitals would do more harm. In ALL CAPS text they come out lowercase.
            • Your own abbreviations. Local program names and agency initials aren't on the list, so in ALL CAPS text they get lowercased. If one comes up often, email hello@writekeys.net and we'll look at adding it.

            The other case buttons

            • UPPERCASE makes every letter a capital.
            • lowercase makes every letter small, except the acronyms on the list while Keep acronyms is on.
            • Title Case capitalizes each main word, for headings and names. Short words like and, of, the, and to stay lowercase unless they start the line.
            Before
            DISCHARGE PLAN AND FOLLOW-UP CARE
            After: Title Case
            Discharge Plan and Follow-Up Care

            Questions

            How do I turn off acronym keeping?

            Untick Keep acronyms, next to the case buttons. Every word is then converted, CHF included.

            Can I add my own acronyms?

            Not yet. In text that mixes capitals and small letters, short words in capitals are already left alone, which covers most local acronyms. For ALL CAPS text, email hello@writekeys.net with the terms you see most.

            Does it work on text that isn't in capitals?

            Yes. Words that don't start a sentence are lowercased, so Text Typed Like A Title becomes Text typed like a title. The acronyms on the list are still kept.
