Problem solved

Tessera solves the problem of AI assistants having no persistent memory of your personal context, forcing you to re-explain yourself every time. It gives you a portable, inspectable memory that you control and can take to different AI models, so answers are personalized and private.

Use cases

• Ask a personal assistant to plan a week around your calendar, dietary preferences, and family commitments
• Set reminders in natural language and get nudges at the right time
• Store and retrieve people details like birthdays and preferences
• Keep notes, plans, and documents in a private memory that syncs across devices
• Generate images from text descriptions in the same conversation
• Switch between major AI models mid-conversation while preserving context
• Search your own memory to see what the assistant knows about you
• Connect external apps to bring context into the assistant

Audience

• Business Users
• Product Managers
