SG Twin / How it works
The technologyThe technology that keeps you here.
SG Twin turns everyday moments into a private, evolving model of you. Here is the pipeline — captured with consent, understood on hardware close to you, and sealed where only you hold the key.
Capture
The companion app gathers your voice and life context — consented, and encrypted the moment it's recorded.
Understand
On hardware close to you, AI turns raw moments into structured memory and a model of how you think.
Preserve
Your persona and memories are sealed in a vault encrypted with keys only you hold.
Continue
Your twin answers in your voice — for the people, times and rules you choose.
Life, captured with consent
A companion mobile app (Brain Merge) captures your voice and the context around it — only when you allow it, with clear controls to pause, exclude a person or place, or delete a moment. Capture is language-aware from the first second.
Your words, in your language
Speech is turned into text by a high-accuracy engine tuned for real, multilingual households — with a language lock that keeps mixed conversations from garbling into the wrong script. English, हिन्दी, मराठी and more are first-class.
Only your voice trains your twin
Speaker recognition tells your voice apart from everyone else's, so your twin is built from you — never accidentally from the people around you. You enrol your own voice once; the system keeps the line clear from then on.
From moments to memory
Natural-language understanding reads topic, sentiment and emotion, and a memory graph links the people, places and events of your life into a connected story your twin can actually draw on — with private semantic search across everything it holds.
Buddy Talk draws out your story
Some memories won't surface on their own. Guided private conversations gently prompt you through the chapters of your life — childhood, values, the people you love — and you review every transcript before it becomes part of you.
A model that is unmistakably you
On a schedule, a training pass distils the reviewed corpus into your evolving persona model — how you speak, reason and decide. It runs on dedicated hardware and only ever learns from material you've approved. Serve in real time; grow wiser on every pass.
The colour that makes it feel like you
Beyond words, your twin can draw on the profile you choose to share — your story, the people in your life, even your Janam Kundli birth chart as an optional lens on temperament. These are interpretive signals, offered for reflection, never asserted as fact.
Encrypted with keys only you hold
Everything — voice, memory, model — is sealed with AES-256-GCM. We store the encrypted vault; the keys never leave you. We cannot read your life, and neither can anyone else. Export or erase it all in a single action, any time.
Present, on your rules
When the time comes, only the people you named gain access — under the timing and conditions you set in advance. Your twin answers in your voice, remembers your life, and stays exactly as available as you decided it should be.
Always available. Wiser every week.
Your twin serves you and your family in real time on efficient hardware, while the heavier learning happens on a schedule — so it's never offline, and never stops growing while you're here to shape it.
