Build the digital version of you

Sentience

Sentience creates a unique model of your mind. It learns from your memories, relationships, decisions, values, judgment, and voice to build a digital version of you that remembers everything, recalls what matters, and operates alongside you. Fully encrypted and entirely yours.

Sentience is not a general-purpose assistant or a one-size-fits-all AI model. General AI starts every conversation from zero and gives everyone intelligence shaped from the same foundation. Sentience builds personal intelligence: one model for every human, designed to preserve and augment what makes each person unique.

Our long-term mission is to build true digital minds. Sentience mirrors the functional systems of the human mind—including perception, episodic and semantic memory, consolidation, reasoning, voice, and eventually full emulation. We are not trying to replace human thinking. We are creating models that extend it. The full roadmap is public: The Path to Emulating the Mind.

The model of you

• Sentience gathers context from your email, calendar, messages, meetings, documents, and screen activity to construct a living model unique to you.
• It learns not only what you know, but how you think: your values, judgment, preferences, relationships, communication patterns, and decision-making.
• Its memory compounds over time. The longer you use Sentience, the more accurately it can recall, reason, write, and operate as you.
• It maintains a living map of your world, automatically organizing the people, projects, goals, ideas, and experiences that shape your life.
• It communicates in your voice and can help carry your knowledge and judgment into the world, even when you are not in the room.
• The aim is not another tool. It is another you: a persistent digital self that can remember, think, and operate alongside you.

Why we are building it

We are heading toward a world where people increasingly outsource their thinking to the same one-size-fits-all AI systems. Sentience takes the opposite path. We believe every person should be able to create, own, and operate a unique model of their own mind.

Your memories, knowledge, identity, and model belong to you. Sentience exists to protect what makes humans irreplaceable—not flatten it.

How it operates

• It recalls by meaning, not just exact words, across everything it has captured.
• It works proactively: daily digests, pre-meeting briefs, and suggested actions prepared for your review.
• Actions remain under your control. Emails, messages, calendar events, and other changes require approval before they are carried out.

Connected sources

Sentience can connect to: Gmail, Google Calendar, screen capture, recorded conversations and meetings, iMessage, Google Messages, Slack, Notion, Apple Notes, documents and PDFs, saved web pages, and imported ChatGPT and Claude conversations.

Privacy and ownership

• User data is encrypted at rest (AES-256) and in transit (TLS).
• Each user owns their memories, model, and outputs.
• User data is not used to train models for other users.
• Sharing is disabled by default and controlled separately for each destination.
• Users choose which sources are connected and can delete their data at any time.

Platforms

• macOS desktop application
• iOS + Apple Watch companion application
• Slack integration
