One source.
Every reader sees the right version.

ProsperAI is a personalization layer that sits between digital content and the person about to read it. Books, news, and social feeds are adapted, or properized, by AI on your device, before they're shown — tuned to each reader's age, reading level, and sensitivities. The original is never altered, and nothing is decided for you by a platform.

One app, two roles — it asks who is using the device. It's web-based: nothing to install, just open it — or add it to your home screen. Android app coming.

One story, five properized versions for five readers
The problem

Content is one-size-fits-all. Readers aren't.

An eight-year-old, a teenager, their grandmother, and an ESL reader open the same article and get the same words. Today the only alternative is platform moderation — a distant server deciding what everyone gets to see, with no personalization, no transparency, and your preferences uploaded to someone else's cloud.

🚫

Blunt filters

Server-side moderation either blocks content entirely or lets it all through. There's no "make this readable for my child" — only walls.

🏢

Centralized control

Platforms decide for every user at once. One policy for millions of very different readers — and the original speech gets suppressed for everyone.

🔓

Privacy trade-offs

Cloud personalization means shipping your family's profiles, sensitivities, and reading habits to a server you don't control.

How it works

Five steps, all on your device

ProsperAI runs its client-end editing method every time new content arrives — automatically in the background, or on demand.

Load

Content arrives on the device — a book, an article, a feed — from local or cloud storage.

Generate prompt

ProsperAI assembles an AI prompt from the reader's stored profile: age, reading level, sensitivities, preferences.

AI properizes

An AI rewrites, simplifies, redacts, or re-tones the content — before it is ever rendered.

Guardian approves

Optionally, a parent or the reader previews the edit side-by-side and approves it — or revises the prompt and tries again.

Read

The tailored version is displayed or read aloud. The original stays intact, one toggle away.

🔒
Client-end by design — that's what "Make First Amendment, Right" promises. Prompt generation, profiles, and output control live on the reader's device — not on a platform's server. The same source can become a different edition for every member of the household, without the original ever changing for anyone else.
Use cases

The same engine, everywhere content meets a reader

We don't filter. We properize — fit the same source to the person about to read it, without changing it for anyone else.

🎒

Child & youth education

Textbooks, e-books, and articles adapted to a child's reading level and maturity — vocabulary simplified, sensitive material softened, educational goals kept. Guardian approval built in.

🗞️

Newsfeed tuning

Read the news your way: neutral summaries, fact-focused rewrites, reduced emotional charge. The original reporting stays available — you choose the presentation, not the platform.

💬

Social media, made readable

Incoming posts and messages adapted for younger viewers on their own screen: profanity rephrased, graphic detail masked, unsuitable posts replaced with contextual placeholders — without touching the original post or anyone else's feed.

Interactive demo

Watch one text become five editions

Run the full properizing flow yourself: pick a reader, inspect the prompt ProsperAI generates on-device, review the AI edit as a guardian, then read. Works instantly offline — or bring your own API key and edit any text for real.

One app, two roles, one standard you set

The newest embodiment of the engine: the standards desk a parent or a teacher works from, and a children's reading shelf, in one app that asks who is using this device. Content arrives, is properized per reader on your device, and lands on each reader's shelf already just-right — while every "may I see the original?" goes back to whoever set the standards to decide.

💡 Best way to demo: open the two roles side by side in two windows — the role is remembered per tab, so one app can be a guardian on the left and a reader on the right. Posts, requests, decisions and discussions sync live between them, entirely on your device, no server involved.

📲 Put it on real phones

Point a phone's camera at a code — the app opens in the phone's browser and installs from the share menu (Add to Home Screen). One icon; the who's-using-this screen does the rest. The codes always encode this site's current address, so they keep working wherever the site is hosted.

Technology

One engine, three ways to ship it

At the core is a proprietary client-end editing engine: reader profiles, prompt generation, and output control all live on the reader's own device. The same engine powers three delivery forms.

The method

Client-end editing flow

Content is adapted on the reader's device before it is ever shown, with an optional approval loop.

Load source content Generate AI prompt from profile Execute AI editing Validate & approve (loops back if rejected) Output edited content
Standalone app

The ProsperAI app

A self-contained application for phones, tablets, and computers — guardian login, profile configuration, freeform prompt control, and manual / automatic / batch modes.

Guardian controls & login Configuration + freeform input Content loading AI calling & processing Visual & audio output
Host-app add-in

ProsperAI inside the apps you already use

An add-in that intercepts content inside e-readers, browsers, and social or messaging apps — editing new content in real time or in the background, before it's ever displayed.

Content interception Prompt configuration & profiles AI-assisted processing Host display & audio output
On-device prompt generation — profiles never leave the device in full.
Local, encrypted profile storage — sensitivities are family business, not platform data.
Prompt anonymization before any remote AI call.
No server-side storage of edited content unless the user authorizes it.
About

What ProsperAI.us is, and what it sets out to do

ProsperAI is SaaS software for client-end AI editing — a personalization layer that adapts what a person reads on their own device, before it is displayed. It runs as a web app today; the Chrome add-in and the native Android app are built and not yet listed in their stores.

And what it is not: a censor, a filter, or a blocklist. Nothing is removed, and the original is never altered for anyone — the same source simply arrives fitted to the person about to read it.
