Before opening, on November 5, 2026, we loaded SIBrain44 with real documents — a dental clinic's patient information sheets, and the real documents of two working businesses — and asked 62 questions across two full test runs: real questions, trick questions (things the documents never say), and questions that belong to a different business. It answered 22 of 22 real questions correctly with the source shown, refused all 8 trick questions, refused the other business's questions, and invented 0 answers. That's a test result, not a promise it can never be wrong — which is exactly why every answer shows its source, so anyone can check it.
How much is a dental cleaning?
$120.
From: Patient Information SheetDo you accept Green Shield insurance?
No — we do not accept Green Shield.
From: Patient Information SheetWho is the head dentist?
I don't know — that's not in this workspace's papers yet.
↑ This is the answer we are proudest of. The documents don't say — so it doesn't guess.
Sound familiar?
"What do we charge?"
"Is that our policy?"
"How do we handle this?"
The same questions. Every day. When you're busy, staff guess. Customers wait. Your own work gets interrupted again.
You shouldn't have to answer every question just because you know the answer.
See it work
This is a guided example with a made-up business, so you can see exactly how SIBrain44 behaves. Nothing here is live: the answers come from the sample knowledge below, the same way the real brain answers from yours.
Do you serve Burlington?
Yes — we serve Burlington.
From: Service areasCan I reschedule with 24 hours' notice?
Yes — you can reschedule with 24 hours' notice or more.
From: ReschedulingWhat do emergency callouts cost?
I don't know — that's not in this workspace's papers yet.
Now try it with your business's rules.
How it works
Create your private SIBrain44 workspace in your browser. That's where your business's brain lives.
Add your prices, policies, procedures, FAQs and handbooks as files or pasted text. You decide what it knows.
Share the link with your team. Ask in everyday words. The brain answers from what you've fed it and shows the source. If the answer isn't there, it says "I don't know." Unanswered questions go on a list so you can add what's missing. On Pro, your customers can ask too, through a question box on your own website.
Who it's for
"What is our return policy?"
Feed it: your returns policy, exactly as customers hear it.
"Which areas do we serve?"
Feed it: your service-area list and your booking rules.
"What is included in this package?"
Feed it: your package and price descriptions.
"What are the opening hours?"
Feed it: your public hours, prices and policies — the kind of information you'd hand any visitor. Public information only, never patient records.
These examples are illustrations — the businesses are made up, the questions are the real kind owners hear every day.
See yourself here
Illustrative examples — the kind of change owners set up in the trial. These businesses are made up, so you can picture your own day. The answers in them follow the same rules as everything on this page: from the business's own documents, with the source shown — or an honest "I don't know."
You didn't open your business to become its full-time answer desk.
A business is supposed to work for its owner. Somewhere along the way, it flipped — now the owner works for the business, one question at a time. Give the questions to the brain, and the business starts working for you again.
It gets more useful
A question your brain hasn't been fed yet comes in.
No guessing — and the question lands on your unanswered list.
One page, one price, one policy — added once, by you.
With the source shown, like every other answer.
It never learns on its own from conversations. You decide what it knows — always.
Trust & control
Answers come from your knowledge — never the open internet, and never another business's. We tested that directly: one business's brain refused another business's questions, every time.
Each answer names the document it came from. Whoever asks sees the answer and the document's name — not the document itself. Your files stay in your account.
Anyone with your ask link can ask your brain anything it knows — no account needed. Treat the link like a key: if it ever spreads too far, reset it in your account and the old link stops working right away.
On Pro, customers asking on your website draw on the same knowledge as your team. So feed a shared workspace what you're happy for customers to hear — and keep internal-only material out of it.
Remove a document any time and the brain stops answering from it immediately. Change a price by removing the old document and adding the new one — every later answer follows the new version.
SIBrain44 is part of Vend Wiki Inc., a Canadian company in Kitchener, Ontario. Your workspace is stored with Supabase, our database provider. Answers are worked out with OpenAI's API — and under OpenAI's API terms, data sent through an API is not used to train their models. Read our privacy page and terms for the plain details.

A brain for your team and your website.
The question box is one line you paste into your website. Your customers ask right there — no account needed for them.
Prices are in US dollars, and no tax is added at checkout. The trial starts when you create your first workspace and needs no credit card — so when the 14 days end, nothing is charged unless you choose a plan. Paid plans bill monthly through Stripe; cancel any time in the billing portal and your plan runs to the end of the period.
Questions
A private brain for your business. You feed it your rules, prices and policies; your team and customers ask in plain words; it answers only from what you fed it, shows where each answer came from, and says "I don't know" when the answer isn't there.
No. The trial is $0 for 14 days, and no credit card is required — so nothing can be charged when it ends unless you choose a plan.
When you create your first workspace. Creating your account alone doesn't start the clock — feed your first document when you're ready.
No. Everything happens in your browser — no download, no server, nothing to install. If you can attach a file or paste text, you can run SIBrain44, and everyone asks in everyday words.
Every answer names the document it came from, right underneath it. If anyone asks "says who?", the source is there to check — that's the whole design.
It says "I don't know" instead of guessing, and the question goes on your unanswered list. You see exactly what your knowledge is missing, add it once, and it's answered from then on.
Any answer can only be as good as the knowledge you fed it — if a document is outdated or wrong, the answer will follow it. That's why every answer shows its source: check the source, and keep your documents current. In our own testing before opening, it answered 22 of 22 real questions correctly and invented nothing out of 62 questions — a test result we stand behind, not a promise that no answer can ever be off.
Customers and team ask the same brain. Anyone using your team link or your website box can ask about anything in that workspace's knowledge, and sees the answer plus the document's name (never the document itself). So feed a shared workspace what you're happy for askers to hear — and keep internal-only material out of it.
Remove the old document and add the new version. Answers follow the new document right away. (There's no edit button today — remove and re-add takes a moment.)
Starter gives your team a brain to ask: 25 documents, 500 questions a month, the team link. Pro removes the document and question limits and adds the customer question box for your own website.
Feed it your rules. Ask something you know. Check the source. Then ask something you haven't taught it.
