for teams drowning in PDFs, sheets, and Drive folders

Your documents already know the answer.

Q-brain turns your company's PDFs, spreadsheets and Drive folders into a chat that actually knows your business — and shows exactly which document, sheet, and row every answer came from.

Ask something about your documents…

A private brain for your company's documents.

Every company has knowledge scattered across contracts, spreadsheets, policy PDFs, and a Drive folder nobody fully remembers the structure of. Q-brain reads all of it once, and lets your team ask questions in plain language instead of searching file by file.

It's not a general chatbot with your logo on it. Q-brain only answers from your own documents — if the answer isn't in there, it says so instead of guessing.

Each company gets its own isolated space. Nobody outside your team — not other clients, not even Q-brain's own admins — can read your documents or conversations. Ever.

Available as a web chat for your whole team, and as a Telegram bot for quick questions from your phone (Pro plan).

Everyone knows where the info is. Until they don't.

The same three problems show up in every company, regardless of size.

Knowledge lives in five different places. Some in Drive, some in an inbox, some in a spreadsheet only one person understands.

Nobody can verify an answer. Someone remembers "something about a discount policy" but not which document, or if it is still current.

Generic AI chatbots don’t know your business. They are confident, fluent, and wrong — because they were never given your actual documents.

From a folder of files to an answer, with proof.

01

Upload your documents

PDFs, Excel sheets, Word docs — or connect a Google Drive folder. Anyone with the right role in your team can manage this.

02

Q-brain indexes everything

Every document is read and broken into pieces Q-brain can search — spreadsheets row by row, so a single cell is still traceable back to its sheet and row number.

03

Your team asks questions

In the web chat, or via Telegram on the Pro plan. No training, no prompt engineering — just plain questions.

04

Answers come with sources

Every response shows exactly which document (and which row, for spreadsheets) it came from. If nothing in your documents answers the question, Q-brain says so.

Built for how companies actually store information.

chat

Team-wide web chat

Everyone in your company chats with the same knowledge base, scoped to their role.

telegram

Ask from your phone

A Telegram bot linked to your company, for quick questions without opening a browser. Pro plan.

roles

Two roles per company

Members can chat. Managers can also upload, edit, and remove documents.

sources

Every answer, sourced

Document name, and for spreadsheets, the exact sheet and row the data came from.

excel

Row-aware spreadsheets

Each row is read as its own fact, headers included — not flattened into unreadable text.

guardrail

Won’t wander off-topic

If your documents don’t cover it, Q-brain says so instead of inventing an answer.

Your documents. Only your team. No exceptions.

Complete isolation between companies

Enforced at the database level, not just in the app — one client can never see another’s data, even by accident.

Not even Q-brain staff read your content

Our own admin console shows usage and plan status — never the contents of your documents or conversations.

Documents treated as data, not instructions

Text hidden inside a file can’t manipulate the assistant into ignoring its rules.

Two roles, enforced server-side

Members chat. Managers manage documents. Permissions aren’t just hidden buttons — they’re checked on every request.

Questions we get before someone signs up.

What happens if I update a document?

Upload the new version — Q-brain replaces the old content so answers never mix outdated and current information.

Can everyone at my company see everything?

Only what is uploaded to your company’s space. Within it, members can chat and managers can also manage documents — there is no company-wide "everyone sees everything" default beyond that.

Is my data used to improve Q-brain for other companies?

No. Each company’s documents and conversations are isolated and are never mixed with, or used to train models for, anyone else.

What if Q-brain does not know the answer?

It says so, instead of guessing. If nothing in your documents is relevant enough, you get a direct "I don’t have that information" instead of a confident-sounding wrong answer.

Do I need a credit card for the trial?

No. Trials are set up manually over email, and billing for paid plans is arranged directly with us — no self-serve card charges.

Can I cancel or change plans?

Yes, at any time — email us and we will adjust your plan or usage limits directly.

Stop searching. Start asking.
