How it works

Text one number. A long-memory AI does the rest.

Brumo lives where you already text — iMessage, with SMS fallback on Android. There's no app to install, no feed to scroll. Here's the whole model in five steps.

01
Save Brumo's number
Add +1 (470) 637-4108 to your contacts, or tap the CTA on brumo.app to open iMessage with him already typed. There's nothing to download.
02
Say hi
Send "hi brumo" or any first message. Brumo replies warmly and asks your name. That one exchange creates your account behind the scenes — no forms.
03
Text him like a friend
Tell him what's on your head — reminders, moods, goals, plans, the small stuff. He responds like a contact, not a tool. No menus, no commands.
04
He remembers what matters
Brumo pulls context from every past message to stay useful. Three weeks later, he'll bring up the thing you mentioned once — without being asked.
05
He nudges you when it's time
Reminders, follow-ups, and gentle check-ins arrive as iMessages at the right moment. Never floods your phone. Reply STOP any time to go quiet.

Why iMessage?

The inbox you already check dozens of times a day is the right home for a personal AI. No new app to download. No new habit to build. No homescreen real estate to fight for. Brumo shows up like any other thread — next to your mom, your best friend, and your dentist. That's the whole design principle.

On iPhone and Mac, you get the full iMessage experience — typing indicators, read receipts, tapbacks, photos. On Android (or when iMessage can't reach us), Brumo falls back to standard SMS without losing memory or context.

How memory actually works

Brumo uses two kinds of memory. Short-term is the recent chat history — the last day or two, used as immediate context. Long-term is a set of durable facts extracted from your messages — names of people you mentioned, goals, promises, moods, life events.

Every reply pulls the right slice of long-term memory based on what you're talking about. If you told Brumo three weeks ago that your sister is moving to LA, and you mention her again today, he knows — without you having to remind him.

You can inspect this memory from the Brain tab in your web dashboard, and delete any item or the whole thing at any time.

Proactive — but never spammy

On Pro, Brumo can text you first. He might ask how an interview went, remind you about a birthday you mentioned weeks ago, or check in if you've been unusually quiet. But there are strict rules: active-hours windows, per-type cooldowns, and backoff when you've been ignoring him. He'd rather stay quiet than be annoying.

You can turn proactive messages off with a single toggle in the dashboard, or set quiet mode by just texting him “quiet til 7am”.

Privacy, in plain English

Your thread is scoped to your phone number. It's never sold, never used to train third-party models, and never shown to advertisers. Reply STOP to any Brumo message and he goes quiet. Email us to delete everything — we honor requests within 30 days. Full details on the security page.
