Prokopton42 invites you to speak with voices built from texts. These terms apply when you use the site.
You can read works, explore their sources and talk with voices inspired by thinkers such as Seneca and Marcus Aurelius. AI produces these voices using texts and historical rules. They are not the people themselves. Their replies are invitations to think; they cannot replace the sources or your judgment.
Keep your sign-in details private and tell us if you suspect someone has used your account. You are responsible for the messages and documents you add; share only material you have the right to use. Do not use the site to harass anyone, break the law, disrupt the service or access another person’s account or data.
An accurate citation does not guarantee a sound interpretation. Check the passages shown and feel free to challenge a reply. Do not make a medical, legal or financial decision based only on a conversation here; consult a qualified professional when the situation calls for one.
The Library brings together works, editions and translations with different rights. Access on Prokopton42 does not grant a general right to copy, redistribute or use them elsewhere. Check the information for each document before reusing it. Your personal documents remain yours; you permit us to process them in the conversations where you attach them in order to provide the service.

We may change features, correct or remove content, and temporarily interrupt the service for maintenance or security. We cannot guarantee uninterrupted access. If these terms change substantially, the new version will be published on this page.
