Lexikon AI is a tool that allows you to roleplay with personalized AI companions based on past text conversations.

The platform can process text conversations from any messaging app to create interactive AI versions that emulate the communication style, personality, and memory of the original communication partner with impressive accuracy.

To create your AI companion, you can simply record your screen displaying a text conversation and securely upload it to the platform. The proprietary AI then processes this recording to create a custom companion that mirrors the person in the conversation, enabling users to continue the conversation with the AI companion.

The AI companion retains memory of details and context from the original conversations, fostering naturalistic and relevant interaction. Users can also guide their persona by providing specific instructions on topics to emphasize or avoid during the conversations.

Security and privacy are key focus areas for Lexikon AI. It adopts measures like automatically deleting user recordings after 24 hours, strong encryption and a policy against AI training on users' conversations. Lexikon AI is available the web, Google Play, and the Apple App Store.
