Workers described mental fog… and the strange sense that their thinking had become crowded.
Memoir is a private AI memory companion. A digital version of your mind that captures the people, moments, and commitments that shape your life — and helps you recall what matters when it matters.
The problem
Important details — about people we love, promises we made, ideas worth keeping — end up scattered across notes, calendars, screenshots, group chats, and our own minds. Forgetting isn't carelessness. Everyday life simply outpaces what one mind can hold.
The cost isn't just inefficiency. It's the small guilt of missing a friend's news. The frustration of an idea you can't quite recall. The quiet sense of falling behind on your own life.
What Memoir is
Not a notes app. Not a journal. Not another to-do list. Memoir is a new kind of AI companion — one that captures everyday moments through quick voice or text, quietly reads what's already in your phone (calendar, email, notes), and turns it all into structured memory you can return to. Not to replace your mind. To stand beside it.
The research
We surveyed nearly 200 people across 15 countries about how memory shapes their day-to-day. Three findings shaped Memoir.

higher emotional impact felt by women than men when forgetting personal details. Memoir is built with that gap in mind.
Voices on the shift
Researchers, journalists, and clinicians are converging on the same idea — that modern life has overwhelmed the way we remember.

GenAI tools are analyzed as cognitive extensions that offload memory work to machines.
Stronger social connection — including frequency of interaction — is associated with lower dementia risk.
The act of taking digital photographs has been found to decrease recall accuracy for non-photographed aspects.
Digital narratives… afford opportunities for expression but also pose challenges such as identity fragmentation.
How it works
Speak or type in seconds. The bar is as low as a WhatsApp to yourself. Memoir also reads your calendar, email, and notes — so most of what matters gets captured without you lifting a finger.
Memoir understands what you said and turns it into a memory card, anchored to a person, a moment, a promise. Matt today is the same Matt from last month.
Search, ask Memoir a question ("what should I remember before seeing Diego?"), or browse memory cards by person and theme.
Quiet, high-confidence reminders. Lunch with Sara tomorrow — ask about her new job. Never noisy. Never demanding.
Meet Pulse
Pulse is the home of Memoir. Four cards that show you what's coming and what matters — quiet enough to know when to step back.
In practice
Memoir gently surfaces that she just started a new job, and what you talked about last time.
The recipe she mentioned. The story about your grandfather. Saved before it slips.
Saved when he said it. Surfaced when there's room in your week to plan it.
Trust & privacy
Privacy is not a footer afterthought at Memoir. It's the posture of the product — and the way we ask you to trust us.
User-controlled recall, deletion, and export.
No ads. No selling personal data. Ever.
Sensitive memories handled with care — never surfaced unprompted.
Memoir asks; it doesn't assume.
