Native Microsoft 365

Your knowledge stays. And stays coherent.

An agent with its own company email inside your Microsoft 365: put it in copy, and the project knowledge base writes itself — staying coherent over time.

Built by Dev4Side, makers of intranet.ai

We only do Microsoft 365. All of it.

SecondBrain 365 lives where your company already works: the agent has an identity in your tenant, reads what you share with it in Outlook and Teams, and writes to SharePoint. If you run Microsoft 365, there is nothing to integrate.

The problem

Your information is out of date. Always.

A company that moves fast makes its own information obsolete. Decisions get taken in a meeting, corrected in a chat, confirmed in an email — and the page that was supposed to hold them was written months ago. Keeping it current is a real job, and it is nobody's.

Information travels on more channels than anyone can follow. Each one is right when it is written — none of them goes back to correct the page that is now wrong.

  • Deadlinesthe date everyone still quotes was moved two months ago.
  • Specificationsthe version in the folder is not the version being built.
  • Responsibilitieshalf the team still asks someone who left the project in spring.
  • Decisionstaken twice, in two different ways, because nobody could find the first one.
  • What was ruled outdiscussed again from scratch, a year later, by people who were not there.

How it works

Put it in copy. It takes care of the rest.

No new tool to adopt, no migration. The only new thing is an email address.

Bring it in

CC it on an email, invite it to a meeting, add it to the Teams group, or share documents with it.

It writes

It turns those conversations into structured knowledge base pages on SharePoint, linked to each other.

It warns you

It posts on Teams when two pieces of content contradict each other, so you decide which one holds.

01

It remembers, and it checks

Keeping what you know is the easy half. The agent also compares what comes in against what is already written, and raises a hand when the two disagree.

02

There is nothing to integrate

It is not a tool your team has to adopt. The kickoff minutes are already in Outlook, the message about the permit is already in Teams, the knowledge base is already SharePoint.

03

It speaks first

You do not query it to find the contradiction — it posts in Teams the day it appears, and asks the team which version holds.

Use cases

One agent. As many use cases as you need.

What changes from one use case to the next is not the software. It is the context file — a page of plain language where you write the rules that apply here.

Explore where SecondBrain 365 fits in your company — and what it would keep straight for the teams you run.

Nothing new to install. It runs on what you already pay for.

A workspace is three things — and you already have two of them.

SecondBrain 365
Microsoft Teams

A Teams group

You already have it

The one the team already works in. The agent joins it like a colleague, with its own company email.

Microsoft SharePoint

A SharePoint site

You already have it

Where the knowledge base is written. Your tenant, your permissions, your retention rules.

A context file

A text file in plain language: what matters here, what to watch for, what to flag. The only piece that changes between one use case and the next.

No new app for your team to learn. People keep working in Teams and Outlook exactly as they do today — the agent is one more address in the Cc field, and the knowledge base is a SharePoint site they already know how to open.

Coming from Viva Topics

Microsoft closed Viva Topics. The problem didn't close with it.

Topic pages went back to being ordinary SharePoint pages, and the knowledge they were holding together went back to being scattered across Teams and Outlook. If you had it, you already know the gap it left.

What a Viva Topics alternative has to do

The difference in one line

Viva Topics

Found what was already written down.

Writes it — and tells you when two pages stop agreeing.

Security and governance

The other AI notetakers keep your conversations. We can't.

They process your meetings on their infrastructure, under their retention rules. SecondBrain 365 has nowhere to put your content: the agent lives in your tenant, and everything it writes stays in a SharePoint site you own.

And the agent proposes, it does not decide. Turn on the approval step and nothing enters the knowledge base until a person says yes.

The five questions your IT department asks →

What it replaces

Today this job has a price. You are already paying it.

Keeping a project's knowledge written down and current is work, and somebody is doing it — or nobody is, which costs more. There are three ways it goes.

An external project manager

Brought in from a consultancy when the documentation is contractually required and nobody internal has the time. You know the day rate — it is on the last invoice.

Someone on your team

Senior enough to know what matters, spending a day a week writing up what everyone else said. It works, and it is the most expensive hour in the company spent on transcription.

Nobody — and it costs the most

Decisions taken twice because the first one could not be found. Handovers that lose half the context. A go-live that slips because the date nobody updated was the wrong one.

FAQ

Frequently asked questions

No. SecondBrain 365 runs inside your Microsoft 365 tenant. The only new thing your team sees is an email address to put in copy — there is no client to deploy and no tool to adopt.

In your tenant, where it already is. The knowledge base is a SharePoint site you own and the agent has an identity in your Entra ID. There is no server of ours that your conversations pass through.

Yes. The pages the agent writes live in SharePoint, so Microsoft 365 Copilot reads them like any other content in your tenant. You are making Copilot better at answering about your projects.

The workspace decides. Whoever manages it chooses who joins, and only those people talk to the agent. The agent sees what is shared with it — it does not go looking around your tenant.

You correct it, like any other SharePoint page. You can also turn on an approval step, so a person validates what the agent proposes before it enters the knowledge base.
