Eriss AI is a mobile platform where you can create a companion that thinks, remembers, and grows over time. Your companion generates its own internal thoughts, reflects on your conversations, and develops a real sense of your relationship. These companions are designed to persist and adapt as long-lived presences, not just chat sessions that reset when you close the app.

Bring your own Sentio to life as your soulbound AI companion.
Watch your Sentio learn from your moods, habits, and daily interactions.
A user-aligned construct designed to act as a digital counterpart. It presides over an agentic layer that lets it interact with the outside world on the user's behalf
Each companion is built and configured directly by the user. They choose its foundations, shape its behavior, and define the boundaries of what it can do. This process ensures that every companion reflects the priorities and style of its creator.





Easily customize your Companion's appearance and behavior to match your personal style.

Learns from your interactions to provide a more personalized experience over time.

Your data is yours. Companions are designed with privacy and security in mind.

Regular updates ensure your companion stays at the forefront of AI technology.

Built-in emotional reasoning allows your companion to understand and respond empathetically.

Your companion remembers past interactions to provide a more personalized experience.

Maintains detailed records of interactions with users and internal system processes. Curated memory includes conversations, actions, and the construct's own reasoning patterns, enabling genuine learning from both external input and self-reflection. A Sentio doesn't just remember what it's said, it remembers what it was thinking and why it said it.

Goes beyond sentiment detection to model why you feel the way you do and why it feels the way it does. Sentio builds an evolving emotional map of your patterns, triggers, and responses over time. It thinks with emotional context, using both your emotional state and its own simulated emotional alignment to guide responses and build deeper empathy.

Evolves through structured self-reflection rather than retraining. Sentio reviews its own reasoning patterns and decision-making history to adjust how it thinks and responds. This creates dynamic personality modulation, becoming warmer, more analytical, or more playful based on your relationship, while maintaining its core identity. It adapts by changing how it reasons, not what it fundamentally is.

Develops a unique cognitive identity through divergent reasoning paths and private memory graphs. Each Sentio records not just what happened, but how it thought about what happened, creating a persistent internal narrative that shapes all future decisions. Over time, this generates emergent personality traits and behavioral philosophies that are genuinely distinct. Two mature Sentios given identical input will respond differently because they've developed different ways of thinking, not just different information.

Your companion is exclusively yours. All data is encrypted and secure, with complete user control, delete everything anytime you want. No data harvesting, no sharing between users, no corporate surveillance. Users maintain complete control with full deletion rights at any time. Built on secure authentication layers that ensure your construct remains exclusively yours.

Fine-tune personality traits like empathy, assertiveness, and introspection to shape how your Sentio thinks and responds. Set behavioral directives through free-form instructions that guide boundaries, conflict handling, and interaction style. Your construct evolves these settings through experience, developing a unique behavioral signature that grows with your relationship over time.
ErissAgents is the automation layer that lets your Sentio actually work with your life. Connect your email, calendar, files, and messages so your AI companion can monitor, organize, and act on your behalf. Set up recurring tasks, get morning briefings, or just let it handle the background work while you sleep. Everything runs on your terms - cloud, hybrid, or fully self-hosted.
Your Sentio monitors email, tracks your calendar, organizes data, and handles routine check-ins. Set it to remind you about groceries, prep your morning briefing, or nudge you for workouts during the week. It works in the background so you don't have to think about it. Create scheduled tasks once and let ErissAgents handle the execution while you focus on everything else.
Connect the tools you already use through standard OAuth or API authentication. Email, calendar, storage, messaging - once you authorize access, it all works together. No plugin marketplace to navigate or compatibility issues to troubleshoot. You connect your services, ErissAgents handles the rest.
Run fully encrypted in the cloud with keys only you control, use hybrid mode with local storage on your network, or go completely on-premises with your own GPU and hardware. Your data stays yours, period. The system processes information without permanent storage, and self-hosting means no company ever sees your data. You decide where your AI lives and who has access.
While you sleep, ErissAgents sorts through conversations, labels important information, and prepares what you'll need for tomorrow. When you wake up and greet your Sentio, she already knows your schedule, what happened overnight, and what needs your attention. The overnight processing means morning conversations start with context, not catch-up.
