One article.
Every reader in your class.
The same assignment, rendered at each student's reading level — with every fact intact. The editing happens on the device in front of the reader. Drag the slider.
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.
Nothing is destroyed. It 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.
We can't sell what we never receive
Every company in this category promises not to misuse your child's reading history. ProsperAI is built so there is no history to misuse: profiles live in the browser's own storage and editing runs on the device. That claim is either verifiable or it is marketing, so here is the receipt for the page you are on right 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
- Class standards compose with each home's — the more protective setting wins
- No student reading data leaves the device, so there is nothing to put through a privacy review
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 Prism, a separate app that installs from the browser onto the phone you already have
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.
