How it works
From your inbox to your answer.
Brainstack reads the email, files and AI chats you choose, keeps the facts that matter with the exact words they came from, and gives them to the AI assistant your team already uses.
Read and save
Brainstack reads your email, files and AI chats, and saves what matters.
Connect Gmail or Outlook, Google Drive or OneDrive, and the AI chats your team has in Claude, ChatGPT or Copilot. Then pick the labels and folders Brainstack may read.
Example with made-up data. Brainstack never shows a fact to anyone who can't open the original email, file or chat.
- If the exact words can't be found in the original, the fact isn't kept.
- A second check makes sure those words really say what the fact says.
- It counts how many different people said it, so ten copies of one email still count as one.
Ask
Ask in the assistant you already use.
Your team asks the way they always do, and the assistant answers with your team's facts and shows where each one came from.
Example with made-up data. Each answer uses only the email and files the person asking can open, plus their own AI chats.
Works for your AI agents too: they get the same team memory through the same connection. Brainstack connects through MCP, the open standard for connecting AI assistants to tools.
Turn on what you want
The more you connect, the smarter it gets.
Your IT team chooses what Brainstack can read: email, shared drives, AI chats, or all of them. Each one you turn on helps it connect the dots.
Example. In Brainstack's IT settings, three switches turn on one at a time: Email (Gmail or Outlook), Drive (shared drives such as Google Drive or SharePoint) and AI chats (Claude, ChatGPT or Microsoft 365 Copilot). With email on, Brainstack has the June 18 email in which Morgan sent the final Q3 line review deck to the team and to Jenna Carter at Northgate. With Drive on, it adds the deck itself, which says 3% protects endcap velocity, and links it to that email. With AI chats on, it adds Morgan's Claude chat, where Morgan explained why 3%: lead with velocity, and call out the endcap risk. It links the chat to the deck and the email. Morgan then asks: Why did we go with 3% for Northgate? The answer is stitched from all three: lead with velocity, because Northgate pushed back on 5%, from Morgan's Claude chat, which only Morgan can see; 3% protects endcap velocity, from the deck; and it was sent to Jenna on June 18, from the email.
Every decision stays tied to the reasoning behind it, the file it went into, and the email it went out in.
AI chats need Claude Enterprise, ChatGPT Enterprise or Microsoft 365 Copilot.
Example with made-up data. Morgan asks here, so the answer can use Morgan's own chat. Anyone else gets only the parts from the email and files they can open.
Private by design
Your own AI.
Inside your company.
Brainstack comes with its own AI, and it runs on a computer your company owns. Your email and files are read right there and never sent to an outside AI company to be read.
- Your data stays yoursWhat it learns is stored on that same computer, in your company's hands.
- Your own AIBrainstack's AI runs on your company's computer, in your office or your own cloud account.
- Locked backupsBackups are encrypted, and the keys to open them are kept somewhere else.
- Same access as todayPeople only see what they could already open. Remove someone and their access ends everywhere at once.
When someone asks Claude, ChatGPT or Copilot a question, Brainstack hands over only the facts that answer it, and only ones that person is allowed to see.
For your IT person
Your IT person sets it up once.
They set it up on a Linux machine your company controls: a computer in your office, or a virtual machine in your company's own cloud account (such as AWS, Azure or Google Cloud). They pick which sources Brainstack may read, and a guided wizard walks them through connecting mail, cloud drives and AI chats. After that, your team just signs in with the work account they already use.

Questions
Plain answers.
Something else on your mind? Ask us when you get in touch.
- Is my data safe?
- Brainstack runs on a computer your company controls, and the AI that reads your email and files runs there too, so your text isn't sent to an outside AI company. Backups are encrypted. Each person only sees what they could already open in the original app.
- Do I need IT help to set it up?
- Yes, once. Your IT person or IT provider sets it up on a Linux machine your company controls: a computer in your office, or a virtual machine in your company's own cloud account (such as AWS, Azure or Google Cloud). It needs enough memory and processing power to run its own AI, but no special graphics card. They point a web address at it and connect your company's sign-in, such as Google or Microsoft, and a guided wizard walks them through the rest. After that, your team just signs in. Here's the page for your IT person.
- Which apps does it work with?
- Gmail, Google Drive, Outlook and OneDrive. You choose which labels and folders it can read. In Google Drive and OneDrive it reads Google Docs, Sheets and Slides, Word, Excel, PowerPoint and PDF files, plus plain text and CSV. Everyone signs in with the work account they already use.
- Which AI assistants can use it?
- Claude, ChatGPT and Microsoft 365 Copilot all work with Brainstack. Your IT team connects it once, and everyone signs in with their usual work account. Your team can also look facts up directly on Brainstack's own Facts page.
- Can it learn from our AI chats?
- Yes, if your company is on Claude Enterprise, ChatGPT Enterprise or Edu, or Microsoft 365 Copilot. Your IT team turns it on for each one. Each chat's reasoning stays visible only to the person who had it.
- Will it change my email or files?
- No. Brainstack only reads them. It never edits, moves or sends anything in your inbox or folders.
- What happens when someone leaves?
- Remove them once and their access ends everywhere at the same moment, including any AI assistant they had connected.
- What happens after I reach out?
- We set up a short call to learn how your team works. If it's a fit, your IT person sets Brainstack up with our help. We'll talk about pricing on that call.
