Interactive demo

Watch one text become three editions

You're about to run the full ProsperAI flow, step by step: pick a reader, pick content, inspect the prompt ProsperAI generates on this device, run the AI edit, review it as a guardian, then read. Use the numbered tabs to move back and forth at any time.

Demo Mode — built-in examples with pre-computed edits. Instant, offline, free. Start here.
Live Mode — paste your own Anthropic API key (kept only in this browser tab) and edit any text with a real AI call.
ProsperAI · client-end editor

Who is about to read?

Each profile stores the reader's filtering criteria — age, reading level, sensitivity thresholds, subject-matter limits.

Sensitivity filters

What are they about to read?

Pick a built-in sample — or, in Live Mode, paste any text of your own.

Your text is sent only to the Anthropic API, directly from this browser. No server of ours ever sees it.

The prompt ProsperAI generated — on this device

Assembled automatically from the reader profile, no typing required. You can edit it freely before running. Nothing is hidden from you.

🔑 Live Mode calls api.anthropic.com straight from your browser. The key is held in this tab's session only — never stored on disk, never sent to any other server. That's the client-end principle, demonstrated.

Guardian review

Before anything reaches the reader, a guardian (or the reader themselves) compares the edition against the original. Highlighted passages were changed.

Not approved? The flow loops back to prompt generation so you can adjust and regenerate.

Approved. Here's what the reader sees.

The original is preserved untouched — switching is always one tap away.
