What did I decide about the flat?
I don't have a record of that. Could you remind me?
The Banani one. ৳28,000 a month, moving in on the 5th.
She isn't real. Her memory is.
Every AI forgets you. Subah doesn't. She knows exactly who you are, and she keeps your memories with her till the end of time. Your money, your plans, your people, every word you ever told her: she looks after all of it, like the best companion you could have.
- Speaks Bangla and English
- Voice or text
- Works with Claude and ChatGPT
- Private by design
Subah is an AI persona, not a real person.
You said it once. Only one of them heard.
Every AI you use keeps its own small notebook about you, and none of them share. Your plans sit in one chat, your money in another, the file in a third. So you explain your own life again, every day, to assistants that are each meeting you for the first time.
I'm taking the Banani flat. 28 thousand a month, two months in advance, moving in on the 5th.
Subah heard it, and wrote it down.

Draft the email to the landlord.
Happy to. What is the landlord's name, and what did you agree?
Drafted, with the rent and the move-in date you agreed. Ready when you want to send it.
অ্যাডভান্স কত দিতে হবে?
Sorry, I can't help with that.
৳56,000, two months' rent. It is due on the 5th, and it is in your bills now.
One second brain. Read and written by every assistant you use.
Every light is something you told her.
Behind Subah sits a second brain: one private memory of your life. Mention something once, in any conversation, and it is kept, dated and connected to everything else she knows.
- Said once
Known everywhere
Tell her on a call. A minute later Claude, ChatGPT and her Telegram chat know it too. Every assistant you use reads and writes the same memory.
- Continuity
She picks up where you left off
Each conversation starts from the last one, whichever app or device it happened on.
- Honest memory
What-ifs stay what-ifs
Drafts, role-play and "what if" questions never turn into facts about you. When a real fact changes, she updates it and keeps the old version with its date.
One night. Everything handled.
Ask in your own words. Bangla, English, or both at once.

While you sleep, she is still at work.
Your last call of the day ends. She keeps what mattered and lets the rest go.
She files today's spending and looks at what tomorrow will cost.
New mail comes in. It is sorted before you ever see it.
She walks back through the day and writes its summary.
Old facts are tidied. Duplicates merge. What changed is updated.
She watches your calendar, and catches the meeting that moved.
Tomorrow's plan is laid out before you are awake.
First light. She is ready when you are.
Wherever you are, she already is.
The app
Installs from the browser on iPhone and Android. Today, Talk, Planner, Finance, Email, Files and more in one place.
A voice call
One press of the Action Button, or "Hey Siri", and she is listening.
Telegram
Text her or send a voice note. She answers in text and in her own voice.
Your Mac
A menu-bar clipboard that remembers what you copied on every device. ⇧⌘V and it is there.
Claude and ChatGPT
Her memory plugs into the assistants you already use, through MCP, the open standard they both support.
Reminders
A quiet push at the right minute: the plan, the bill, the birthday.
She keeps a secret better than you do.
The Vault is locked to you
Cards, IDs and bank details are encrypted on your own device. The server only ever stores ciphertext, and Subah herself cannot read it.
No codes in her memory
OTPs, PINs and card numbers are masked before anything reaches her memory.
Nothing is sent without you
She drafts the email. Sending waits for your yes.
Never sold, never trained on
Your data is not used for advertising or to train AI models.
You can make her forget
Delete a memory and it is gone. Her history shows what she knew, and when.
Soon, one of your own.
Today Subah works for one person: the man who built her. Next, she gets siblings. Give yours a name, a voice and a language, connect the AI and the cloud you already use, and she starts remembering for you.

Name her, pick her voice, and start talking. She learns your life one conversation at a time.
সুবাহ means morning.
Every night ends with her knowing a little more about your life than she did the day before. Then the sun comes up, and she comes with you.
One ordinary day, with her in it.
Six moments from morning to night. In each one you say a sentence, and something in your life is taken care of.

Morning
Before your tea cools, the day is laid out.
She reads you the plan while the kettle is still warm: what is on, what moved overnight, and what needs you first.

Three things. The bank at ten, the site visit at three, and Maa's birthday is in three days.

About Subah
Subah is an AI persona, and an agentic platform that gives every AI you use one shared brain: one private memory of a person's money, plans, email, files, people and conversations.
