ProsperAI · client-end AI editing

One story. Five readers. Nothing suppressed.

A local paper files the report below. It goes out to everyone, unaltered, exactly as written — the publisher changes nothing and no platform removes anything. What differs is what arrives, because each reader's own device renders it against standards that reader (or their guardian) set. The original is the first column, kept and always recoverable.

Authored editions are pre-written, instant and free — use these when presenting. Run it live re-edits the original with these four reader profiles and your own key: four requests, a few cents, straight from this browser to Anthropic and nowhere else.

What this screen is arguing

Two of the five readers are adults, and their editions keep every fact — including the forty per cent burns that Milo's and Ava's editions drop. Rosa needs the idioms unpacked, not the news softened. Dan needs short sentences, not fewer facts. Same machinery, opposite outcome.

That is the distinction the patent turns on. Editing at the source is one decision imposed on everybody, and what it removes is gone. Editing at the destination is a different decision per person, made on their own device, with the original intact and one approval away. The speech is never suppressed; the listener is served.

Everything here runs client-side. In live mode the only outbound request is to the model provider, carrying your key and this fictional article — no ProsperAI server sees either.
