Knowledge capture · tacit expertise

The expert always leaves.
The knowledge shouldn't.

Legacy Brain extracts the expertise your best people carry in their heads, through structured interviews, AI-assisted analysis, and a rigorous feedback loop, before it walks out of the door.

The problem

What does your company know that only one person could tell you?

Every business has experts whose knowledge, built over decades, exists only in their heads. When they leave, retire, or are poached, that knowledge goes with them. No handover document captures it. No job description explains it. And by the time you realise it's gone, it's too late.

Our solution

We make the invisible, visible.

Legacy Brain doesn't just record what experts say. It surfaces what they don't realise they know, through our conversational interview process extracting knowledge: the decisions, the shortcuts, the customer relationships that never made it into any manual.

The process

Four stages.

Every engagement runs the same arc: ground the domain, run the interview loop, filter for the right audience, hand over the output.

1

Grounding the domain

Before any interviews, we learn your business from the material you already have. It's a fixed-fee scoping stage that maps which knowledge is at risk, and defines who the knowledge base is for.

You get the first knowledge tree, and a clear picture of what a full engagement would involve.

The interview loop

Structured interviews with your experts, human to human. Each session is transcribed and analysed, emails and existing documents fill the gaps, and each analysis surfaces the questions nobody thought to ask.

The loop repeats, session after session, and the knowledge compounds.

Security and filtering

You verify everything we captured. Sensitive material (contract values, personal details, commercial terms) is flagged, filtered, or kept in a separate knowledge base only the right people can reach.

The output

Three deliverables. Take the ones your business needs.

Case files

Annotated case files

Every key decision, customer relationship, and process: documented, explained, and ready to hand to whoever comes next.

Search

Searchable knowledge base

Structured, searchable expertise. Find the answer to any question your expert would have known instantly.

AI

AI assistant

An AI trained on your expert's knowledge. Ask it anything they would have known, and get an answer they would have given.

Human-led, not AI-led

Why not just use an AI chatbot?

Because knowledge has to be drawn out of people. Experts can't simply list what they know. It surfaces in conversation, when a good interviewer follows up, notices a hesitation, and asks why. Someone who cares, talking to someone who knows, uncovers more than any chatbot ever will.

Questions are never off the shelf, as they change with every company and every session. AI does what it is good at, processing, structuring, and searching what gets captured.

Why Legacy Brain

Built differently, by design.

Speech bubble representing human-led interviews

Human-led extraction

Every capture is led by people who notice what a form would miss: the hesitation, the conversational prompts, and the story behind the decision. Tools can assist but they can't replace the conversation.

Checkmark representing validated knowledge

Validated, not assumed

Every piece of extracted knowledge is verified back with the expert before it enters the archive. Accuracy is built into the loop, not bolted on at the end.

Shield representing secure, future-proof storage

Future-proof output

The knowledge base is stored in plain text and markdown: readable by any AI system, searchable by any tool, and owned entirely by your business.

Case study · UK industrial wholesaler

"It is almost as though those two people never left. Their knowledge is still here, still working. I'd recommend Legacy Brain to any business that has critical knowledge tied up in individuals and no reliable way of capturing it."
