Three weeks ago you told me you'd intro Sarah to Lior. He landed in London this morning — want me to draft it now?
The only thing
you need to remember.
Your passport, your spare-key spot, the wine you liked, the promise you made — kept by an agent that knocks first.
Save anything in chat.
Type, paste, or speak. Numen extracts the structure, gives it a home, and tells you 'Saved.' Nothing else.
Then ask anything later.
Vague queries land. The thing you wrote nine months ago is one sentence away — no scrolling, no folders, no remembering where.
You don't ask. It asks you.
Numen schedules its own outreach. Morning briefs, follow-ups on commitments you made weeks ago, nudges when something you cared about resurfaces — at the moment it matters, not the moment you remember to look.
Your morning: gym at 8, the apartment-follow-up call at 10:30, and the dentist still owes you a callback. Coffee with Alex moved to 4pm.
Last March you called the Coombsville Cab at Andrea's the best wine of the year. The shop on Bellenden has it for £28 — was £58.
Ask one thing. It connects everything.
Numen doesn't keyword-search. It walks the threads between what you've told it — chats, photos, contacts, decisions, promises — and hands back the answer assembled across years and across formats.

Or: “What did I think of that book Lior recommended?” · “Who introduced me to the wine I liked at Andrea's?” · “When did the doctor say to recheck?”
Where you parked. The wine you liked.
The promise you made.
A notes app stores text. Numen knows the difference between a password and a passport, a reminder and a regret, a voice memo and a contact. Eleven typed kinds — each rendered in the form it deserves, each searchable across the others.

Marcus from the gym
Said to text about a pint sometime. Allergic to shellfish — mention that if dinner.

••••••••••••••••People who'd already replaced six apps.
“I haven't dropped a follow-up in three weeks. The commitment tracker is the only feature I've used every single day.”

“Replaced six apps with one. The 'today' brief is what every productivity tool should have built years ago.”

“It's the first AI tool that doesn't feel like work. I just talk to it and things stay remembered.”

Private by design.
A second brain only works if you trust it with the things you wouldn't tell anyone else.

Questions, asked and answered.
The fears people have before signing up. We share them.
Where is my data stored?
On encrypted disk in EU and US regions, your choice. The encryption key is generated on your device and never leaves it — even Numen's servers can't read your memos.
Can I export everything?
Yes, anytime, on any plan. One click gives you a downloadable archive in Markdown or JSON, with attachments, structured exactly the way Numen sees them internally. No dark patterns, no waiting.
Does the AI provider see my private memos?
Only the snippets relevant to a given chat turn are sent to the model, and never stored on the provider's side. We use enterprise zero-retention agreements with Anthropic and OpenAI. Your secrets aren't training data.
What happens to my memos if I cancel?
They stay yours. After cancel you drop to the Free tier — your existing memos remain accessible (read-only past the 50-memo limit). You can export them, delete them, or pick up where you left off if you re-subscribe.
How is this different from a notes app?
A notes app stores. Numen remembers. The difference is recall: ask a vague question months later and Numen finds the answer, synthesises across memos, and shows you patterns over time. Notes apps make you do that work.
Isn't this just ChatGPT with memory?
ChatGPT remembers things you say to ChatGPT — inside one conversation product, walled off from the rest of your life. Numen is a typed memory system: passwords, passports, decisions, contacts, commitments, voice memos, photos, reminders, events — eleven kinds, each with its own structure. And Numen's agent reaches out to you on its own (Pulse) — morning briefs, follow-ups on commitments you made weeks ago. ChatGPT waits until you remember to ask.
Is there a mobile app?
iOS and Android are in beta. The web app at numen.to works on phones today — saving via voice and photo are designed mobile-first.
