GOOD TO KNOW
More about Plum.
Within-tech is the brand name of Within Tech Limited. Plum is the company's first product, exploring AI-native interactive entertainment through fictional characters and interactive stories for adults around the world.
Plum is currently in an invite-only beta ahead of commercialization and has not begun commercial operations. Contact info@plum.top to ask about beta access. Our team will confirm eligibility and how to participate.
Characters and stories offer a natural starting point for ongoing interaction. Text lets users set the pace and express their preferences and imagination, while character details, relationships, story developments, and memories build over time. Text is Plum's starting point; we plan to explore more media and forms of interaction in the future.
We want AI to work alongside people, respecting users' choices and keeping them in control of the story's direction. Plum is intended for adults and supports content safety through a moderation process that combines automated and human review.
The conversations on this page are fictional examples using preset content. They are not connected to a live AI model. The product interface preview may differ from the actual beta experience.
