Biometric Intelligence
Cerebro
Your second brain. Powered by biometrics.
Meet Kit
Hey Kit,
remember this.
Kit is your always-on voice companion. Just talk — Kit listens, thinks, remembers, and syncs everything back to Cerebro. No phone needed.
Two modes, one device
Choose your
voice.
Kit
Deep intelligenceYour cognitive agent. Kit uses long-term memory search via Pinecone and Claude to understand context, recall past conversations, extract insights, and give personalised responses grounded in your history and biometrics.
Aly
Quick companionA lightweight, all-in-one voice chat. Aly runs on Gemini Flash Lite or ChatGPT's speech API for fast, natural conversation — no memory search, no retrieval. Just instant back-and-forth when you want to think out loud.
How it works
Talk. Think.
Remember.
Speak naturally
Kit sits on your desk, nightstand, or anywhere you think. Just talk — it captures your voice using on-device audio processing and streams it for transcription.
AI processes and responds
Your words are transcribed via Whisper, then routed to Kit or Aly depending on your chosen mode. Kit searches your memory and biometrics for context. Aly responds instantly.
Everything is remembered
Conversations, ideas, and action items are stored as vector embeddings in your personal memory bank. Kit recalls them when they become relevant again — days, weeks, or months later.
Syncs to your phone
Everything Kit captures syncs to the Cerebro app over Bluetooth. Review transcripts, browse memories, track your cognitive scores, and see how your biometrics shape your thinking patterns.
Inside the app
Built for the
thinking athlete.
Cerebro reads your body's signals so your mind doesn't have to. Three core systems, one unified score — built on real biometric data.
Cognitive Offload Scoring
Captures ideas and decisions at the right biometric moment — when your body signals you're sharp enough to actually think clearly.
Stress Monitoring
HRV and resting heart rate data surfaces stress patterns before they compound. Know when to push, when to protect your recovery.
Mental Bandwidth Tracking
Sleep, recovery, and strain combine into a single clarity number. Your schedule should reflect your actual capacity, not an assumption.
Data Layer

WHOOP biometrics
Cerebro connects via read-only WHOOP OAuth. We request access to recovery, sleep, and cycle data only. Revoke access anytime in WHOOP app settings.
