Cognitive overhead has never cost more, and AI can finally carry it. Trace is a voice-first AI companion built explicitly for high-agency operators, founders, and professionals who juggle multiple roles, projects, and responsibilities. We believe mental load is the single greatest roadblock keeping ambitious individuals from achieving their best versions. Trace removes this friction entirely by turning your voice into structured, actionable intelligence. Most productivity tools force you to stop what you are doing and manually type out context. Trace takes a different approach: voice is the lowest-friction interface for capturing human context. This is not another note-taking tool. Trace is a proactive context engine that continuously builds an understanding of your life, thoughts, and commitments to help you stay firmly in control. CAPTURE EFFORTLESSLY Record thoughts, spontaneous ideas, complex instructions, and meetings with absolute minimal friction. Trace serves as an on-device application designed to let you speak naturally. Because it supports advanced natural voice processing, you can talk to it just like you would to a trusted chief of staff. ORGANISE AUTOMATICALLY Stop spending hours sorting through unstructured notes or transcribing voice memos. Trace instantly processes your audio recordings to clean up, structure, and categorise your thoughts into useful, rememberable intelligence. It maps out your personal and professional context over time, transforming chaotic brain dumps into clear, structured records. ACT PROACTIVELY An AI companion should do more than just rememberβ€”it should execute. Trace generates precise insights, highlights critical takeaways, tracks action items, and drafts your follow-up tasks automatically. You can chat directly with your AI personal twin to query past conversations, recall specific project details, or cross-reference contextual data from weeks ago. BUILT FOR THE HIGH-AGENCY LIFESTYLE If your day is defined by rapid context-switching, back-to-back meetings, and continuous information consumption, Trace is built for you. It functions as an external intelligence layer across your digital life, systematically carrying your mental load so your brain can focus on deep thinking and execution rather than retention. DEVELOPED BY AI INTERFACE EXPERTS Trace is engineered by a team with deep, real-world experience building production-grade enterprise AI voice systems and full-duplex conversational agents. Built from scratch with an emphasis on low-latency interactions and highly secure data management, Trace brings enterprise-grade AI execution speed directly to your personal workflow. Take control of your digital life, eliminate cognitive friction, and offload your mental overhead to an AI companion that truly understands your context.
