You write all day. Slack messages, follow-up emails, the text you rewrite three times before sending. Nobody tells you whether any of it was easy to read until after it is already gone.
Prose is a notes app with a readability grade in the corner. It updates every time you change a word, so you can see whether your writing is getting clearer before you send it to anyone.
Nothing between your thought and your writing
There is no formatting toolbar, no font picker, no checkboxes, no settings to configure. You open a note and start typing. Because there is almost nothing to the app, it opens instantly and never slows down no matter how many notes you have.
What the grade chip tells you
Tap the grade chip and Prose tells you three things. Whether your reader can follow what you wrote, how long it will take them to read it, and how many words you have, so you know if what you wrote fits in a LinkedIn post, a tweet, or a cover letter before you paste it somewhere and find out the hard way.
See where your reader slows down
The grade is a number. Tap the eye and Prose shows you what is behind it. Sentences that run long, and sentences written in the passive voice, get a soft highlight. Adverbs, filler words, and the fancy word where a plain one would do get underlined. You see the exact spots that slow your reader down, not just a score that says something is off.
It all updates as you type. A sentence lights up the moment it runs long and clears the moment you split it. Long-press the eye to choose which checks are on. Like everything in Prose, this runs entirely on your phone.
What people write in Prose
The notes in Prose are for the things you write that need to land. The email after a kickoff where you want to make sure you and the client heard the same thing. The toast you are giving at your friend's wedding tomorrow night. The message to someone you have not talked to in a while where you need to get the words right. The note to a colleague where you are explaining something complicated and you want them to understand it the first time through.
Warren Buffett explains the insurance business in sentences a twelve-year-old can follow. He writes at a sixth grade reading level.
Most people write at twelfth because school taught them that longer sentences and bigger words meant better writing. The people reading your Slack messages at 4pm on a Tuesday do not agree.
Your draft is where you left it
Prose saves every keystroke automatically. Close the app mid-thought and come back whenever you want. Your draft is where you left it. Everything stays on your phone and nothing is uploaded anywhere.
