One article.
Every reader in your class.
The same assignment, rendered at each student's reading level — with every fact intact. Drag the slider and watch the facts stay put.
Facts still present in the text above
Checked against the words actually on screen each time you move the slider — not a promise, a measurement. Simplifying the language is not the same as removing the content, and this is how you tell the difference.
The two adults get more than the children, not less
A local paper files the report below and it goes out unaltered — the publisher changes nothing and no platform removes anything. What differs is what arrives, because each device renders it against standards that reader or their guardian set. Rosa needs the idioms unpacked, not the news softened. Dan needs short sentences, not fewer facts. Same machinery, opposite outcome — which is the difference between editing for a reader and censoring a source.
← Swipe sideways to move between the five readers. The original is first.
We don't filter. We properize.
Nothing is destroyed, and the original is one request away. A blocker decides for the reader and the decision is invisible and final. Here the reader can always see that something was adapted, can always ask, and a person they know decides — in seconds, with the passage in front of them. That is mediation rather than suppression, and it is the reason a teenager will tolerate this at all.
There is no reading history, because nothing records one
Every company in this category promises not to misuse your students' reading history. Properize is built so there is none to misuse. A version is made for a reading level, never for a named child, so nothing in it can record who opened what — there is no such column to write to. The library of texts holds no student at all; names live in a separate database that only your class can reach, and one press deletes it. Below is the receipt for the page you are reading now.
Two ways in
I teach
Assign one text and let every student read it — the one two grades behind, the one who arrived last spring, the one who needs it in short sentences.
- One assignment, every reading level
- No account, no password, no email — and no roster until you want one
- Texts and versions are kept and shared between classes; student names sit apart from them and delete in one press
I'm a parent
Hand your child a feed, a book, or a browser that arrives already suited to them — and keep the say over what gets opened up, without reading over their shoulder.
- Set the standard once; every source follows it
- Your child can always ask; you decide, and they can see that you did
- Your child reads in ProsperReader — the same app, opened as a reader; it installs from the browser onto the phone you already have
- Nothing is uploaded and there is no account: this half runs entirely in your browser, with your own key
Your child's teacher sent you a code
It is a short link, or a square to scan, or about 380 characters you can paste. Opening it does nothing at all until you press accept — it opens a screen showing you what is in it, and waits.
What it carries
- The classroom's name, the teacher's name, the grade and the subject
- The standards that class reads to — tone, and whether profanity, violence or loaded language are softened
- Any note the teacher wrote about what to soften, shown to you word for word before you accept
What it does not carry
- No student — not yours, not anyone's
- No roster, no class list, no email address
- Nothing your child has read, asked for, or been given
What changes if you accept
- Your child's reading at home also meets the classroom's standards — wherever the two disagree, the more protective one wins
- A teacher can therefore never loosen something you set. Nor can you loosen theirs; you can only leave
- Un-enrol whenever you like, on the Children screen, and it does not come back — a later code from the same teacher updates the standards and puts nobody back in
The code is read on your own device and applied there. Nobody is told that you accepted — not the teacher, not us — which is also why we cannot un-send one for you: if you did not want it, do not press accept.
Three moving parts
The standard lives on the device
Age, reading level, language, sensitivities — written to the browser's own storage by whoever is responsible for that reader, and read back from there. It is never uploaded, because there is nowhere to upload it to.
The edit happens before the paint
Incoming content is held back for the fraction of a second it takes to clean it locally, then upgraded in place when the model's version lands. If the model is slow, unreachable, or out of credit, the reader keeps the cleaned version — never the raw one.
The original is kept, not overwritten
Every edition is stored beside the source it came from, with the standards that produced it. Ask, and a responsible party can release the original into the open reader without a reload.
There is also a browser add-in that does this to pages the reader visits, before they render — try it without installing anything, or see the step-by-step walkthrough of the whole flow.
What this is, and what it sets out to do
ProperAI and ProsperAI are two products sharing one pun. Properize, on this address, is a service your school runs: it keeps the texts and the versions so the next class that assigns the same reading gets it free, and it holds a roster if you give it one. ProsperAI, at prosperai.us, is working software for patent docket CXu001, client-end AI editing — there the browser calls the AI directly with the guardian's own key and nothing is uploaded at all. Both are here; the two doors above lead to one each. See the privacy policy for what each one stores.
The tagline is a play on words, and it is a claim about who decides rather than about which speech should exist. Make First Amendment, Right reads three ways, and each is something the product does. One — nothing is deleted for anybody: the original is never altered or removed, so speech that stays up stays up. Two — free speech has to work, and a passage that overwhelms an eight-year-old is not serving them; each reader gets a version they can genuinely take in, chosen by their own household or teacher. Three — an amendment is also an edit, and the right AI makes the right one for the person about to read, while the author's words stand untouched one toggle away.
The logo is the same pun: Pro·s·perAI / ProperAI, with the s tucked into the checkmark — and it gives us a verb. Properize (v.): to fit a text to the person about to read it, without changing it for anyone else. The longer version of this argument is on the About page.
