October 2026, Last year's approved budget

Claude alone

Fresh chat, no saved company context

You

Armbrain, what was our approved Q4 Google Ads budget last year?

Claude

I don't have your company's approved budget in this chat.
Share last year's plan or approval record and I can find the total and monthly breakdown.

You

Armbrain, what was our approved Q4 Google Ads budget last year?

Claude

Your approved Q4 2025 Google Ads budget was $18,000: October $5,000, November $6,000, and December $7,000.
That's the approved budget, not a report of actual spending.

What changed Armbrain remembers your approved budget and monthly breakdown, so you get your company's numbers instead of a guess.

Fictional illustration, not a captured AI reply. In this October 2026 scenario, last year means 2025. The approval must already be saved or imported; missing or conflicting records call for an honest limitation, not a guess. Thirty days of use does not create last year's history.

Setup guide

Say:

Armbrain, prep my meeting with Northstar Studio.

Client walls

Client A's voice stays out of Client B's draft.

Each client gets its own mind. When you switch to a client by name, Armbrain works from that client's voice, decisions, promises and people, and nobody else's.

Harbor Dental Group

Voice: warm, plain
Decision: one booking page for all 4 locations

Copperleaf Bakery Co.

Voice: say bakeries, not shops
Promise: pie preorders open Dec 1

Every question is locked to one mind. That check runs on every request, both when something is saved and when it is recalled.

How we keep minds apart Security

Fictional clients, for illustration.

What fractional CMOs say

“We got done in 5 hours what would have taken 15.”

Jim ArmstrongPresident, Armstrong Marketing Systems

“It’s my second brain. It remembers everything I can’t remember about my clients.”

Amy ShaneyfeltFractional CMO, Growth Marketing Maven

If I can just take this workload off my mind and give it to Armbrain. Oh my gosh, that changes the game entirely.

Dillon SmithFractional CMO

It’s my second brain. It remembers everything I can’t remember about my clients. I’ve got multiple clients in similar industries, and it keeps them straight. It reminds me, no, that was for this client, not that one.

Amy ShaneyfeltFractional CMO, Growth Marketing Maven

Armbrain remembers changes. I now don’t have to constantly reprompt an AI with the same inputs, over and over, again and again.

Standing work

You don't have to ask. The briefing is already there.

Set up the briefings you want once. They arrive by email or Slack on the schedule you choose.

Every weekday morning
Your morning briefing, across every client.
Monday
Your week, client by client.
After a call
A check on which follow-ups you still owe. Ask for the draft and it waits for your OK.
Friday
What is still open, by client.

Before a call, ask "Armbrain, prep my meeting with Northstar Studio" and the brief takes seconds. With Notion connected, prep notes can also appear on pages you mark as trusted.

SMARTER BY THE MONTH

One month saves you time. Six months in, it knows the business as well as you do.

Day 1
Walk into your next call briefed. Connect your meeting notes or paste in what you have, then ask for a prep.
Month 1
Search past decisions by meaning. Ask why you chose something and get the answer, with where it came from.
Month 6
The next person you hire starts with everything you know. Every decision, preference and promise stays put.

Armbrain knows what has been saved or imported. Thirty days of use does not create last year's history, so import past notes to start further ahead.

KNOWN ISSUES

CLIENT DATA SECURED

Serious security.Small-business simplicity.

Your mind holds your strategy, relationships and decisions. We treat it that way.

Encrypted at rest & in transit

Encrypted on every connection and every record. Data is never readable without an authenticated login.

API keys always hashed

We scramble the API key and never store the original, so your key can never be read back, even by us.

Separate minds

Every query is locked to one mind and enforced on every request, at both ingest and recall. Your data stays in its own sandbox.

Full data deletion on request

A single command wipes every memory, document, and file from a mind, with deletion logged in an audit trail.

What we log

We record which Armbrain tools run, when, and whether they worked. We use it to fix problems and improve the product. We do not store the text of your requests in this log. Details are in our Privacy Policy.

Export when you leave

Package a client mind for a handoff, or export it when an engagement ends. Your information is always yours.

You stay in control.

Follow-up emails are drafted, then held for your OK. That is the default setting.
Armbrain does not book meetings on its own.
New memories from some sources wait in a review queue until you approve them.
HubSpot reporting is read-only.
Your minds are yours. Export one for a handoff, or ask us to delete it, any time.
