Subah, an AI persona, on a Dhaka rooftop at night under warm fairy lights, her hair moving in the breeze

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.

The night goes on

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.

Subah on a call at her desk, writing in a notebook as she listens
Last week, on a call

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.

ChatGPT

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.

Claude

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.

A voice call

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.

Subah on a rooftop holding a glowing paper lantern, the night sky behind her full of rising lanterns

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.

      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.

      1. 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.

        আজকে কী কী আছে?

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

      2. On the way

        The meeting moved. She tells you before you rush.

        Your calendar changed while you were on the road. She caught it in the sync and gives you the new time, so you can stop checking your phone.

        Am I late?

        No. Your ten o'clock is now at eleven. You have time.

      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. You talk to her by voice or text, in Bangla or English, and the other AI assistants you use, including Claude and ChatGPT, read and write the same memory, so nothing has to be explained twice. Subah was built in September 2026 by Tanvir Israque in Dhaka, for his own use first. She is openly an AI persona: her image and her singing voice are generated.

      Three ways into the story

      • The problem

        Your AIs don't talk to each other

        Every assistant keeps its own notes about you. Subah is one memory that all of them share.

      • The maker

        Built after office hours in Dhaka

        Tanvir Israque trained in finance and taught himself to build software. He built Subah for himself first.

      • The persona

        She isn't real, and says so

        Subah has a face, a voice and nine songs to her name, and is declared as an AI persona everywhere she appears.
