Privacy
We never see your chats.
Promptoscope was built so that it does not need to. Here is exactly what happens to your data.
Your chat archive never leaves your device
When you drop a ChatGPT, Claude or Gemini export onto the cast page, it is opened and read by code running in your own browser, in a background worker. It is not uploaded, not even temporarily. You can disconnect from the internet before dropping it and it still works.
Testimony stays with you
When you paste your AI's testimony, only eight numbers, one subject word and the witness name are kept. The evidence lines are saved in your browser's local storage so you can see them on your reading. They are never sent to us.
The link is the chart
There is no database. Your chart is encoded in its own URL (about fourteen characters). Anyone with the link can see the chart, so share it as you like. If you add a name, it is part of the link too.
The connector forgets
If your AI calls Promptoscope as a connector, it sends the same eight numbers, a subject and its own product name. The server turns them into a chart and returns it. Nothing is logged or stored.
Analytics
We use Vercel Web Analytics to count page views. It does not use cookies and does not track you across sites. Chart contents are never sent to analytics.
No accounts
There is nothing to sign up for, so there is no email, password or profile to lose. To forget a chart on this device, clear this site's data in your browser.
Promptoscope is an entertainment project, independent of every AI company named on the site. Last updated November 2026.
