Is my data sent to a public AI model?

Only to the model provider named in the scope, under your account and its terms. I check those terms before any file is indexed, and anything they do not cover stays out of the index.

Who can see the answers?

Only the person who asked, and only for files that person may open. Answers are not shared between staff, and the log records who asked a question without copying the answer into a shared view.

What if a file contains a mistake?

The answer cites the file, so the mistake shows up with its location. The file is corrected at the source, and the index picks up the fix on the next refresh. The answer is not patched by hand.

Can it answer questions the files do not cover?

It should say the files do not cover the question. The accuracy test includes questions with no answer in the files, and the system is tuned until it refuses those rather than guessing.

How does it handle old and new versions of a file?

The index keeps the version that is marked current and removes superseded copies on the refresh. If two current versions exist, the answer shows both and flags the conflict for the owner to resolve.

Do you need admin access to a company drive?

Only the access the scope names, usually read access to the approved folders. I do not need admin rights to the whole account, and the access is reviewed and can be removed at any time.

How long does a knowledge base take to build?

The date is set in the scope after the folders and the permission model are mapped. A small, current set of folders moves faster than a long history with unclear ownership, and the scope states which applies.

Do I need to clean up my files first?

Some cleanup helps, mainly marking which versions are current and removing duplicates. I do that mapping with you as part of the scope, so you do not need to reorganize everything before the first call.

You do. The index sits in accounts you own, and the source list, the permission map and the test set go to you. If you stop working with me, another builder can take over from the same files.

Can staff use it on a phone?

Yes, when the interface supports it, and I test each answer view on a phone before launch. The citation has to stay readable on a small screen, because a source you cannot open is no help to anyone.

What does ongoing support include?

The monthly index review, the update log, the permission review and a test run after each major change. Every recurring cost is listed in the scope, so nothing renews without your knowledge.

Do you only work with Las Vegas businesses?

Most of my clients are in the Valley, and I meet owners in person across Las Vegas, Henderson and North Las Vegas. I also take remote clients, scoped the same way, over calls and a shared project page.

Why Staff Cannot Find Answers

Answers sit in files nobody searches

Most firms hold their answers in files: policies, price sheets, past proposals, onboarding notes and the email threads where a decision was made. The staff member who needs an answer searches by memory, asks the person who wrote the file, or guesses. Each of those costs time and sometimes gets the answer wrong.

A knowledge base is meant to fix that. The risk is that a badly built one answers confidently from the wrong file, or shows a file to someone who should never see it.

What Retrieval Means Here

The model reads only what you approve

RAG stands for retrieval-augmented generation. In plain terms, the system first finds the passages in your approved files that match a question, then has the language model write an answer using only those passages. The model does not browse the open web for the answer and does not fill gaps from its own memory.

That design matters because it lets every answer point back to the passage it used. If no passage matches, the right reply is that the files do not say, not a plausible guess.

Document Sources And Permissions

Access follows each person's files

The index mirrors the permissions the files already have. A person sees answers drawn only from files they are allowed to open, and the permission check runs when the question is asked, not once when the index was built.

Permissions checked at query time, not at index time
Files a person cannot open never appear in their answers
Removed access takes effect on the next question
Shared folders indexed only where the owner approves
No public web search mixed into private answers

Citations On Every Answer

Every answer names its source

Each reply lists the file and the section it came from, so a person can open the original and check it before they act. An answer without a source is not shown, and a reply that cites a file the person cannot open is treated as a permission failure and logged.

How The Build Runs

Five steps from file list to live

1. List the files

The work starts from the folders the team actually uses, not from every file on the server, and mark which ones are current.

2. Set the permissions

I map who can open each folder today, and the index is built to match, not to widen, that access.

3. Index and cite

The files are indexed with section breaks kept, and every answer is set to show its source.

4. Test with real questions

The staff questions from the past month run against the index, and each wrong or uncited answer is fixed before launch.

5. Keep it current

Files added, changed or removed are reflected in the index on a set schedule, and the owner sees the update log.

Private Knowledge Base Security

Private files stay private

A private index is a copy of your files, so it is held in accounts you own and kept under the same rules as the originals. Deleting a file removes it from the index, and the removal is logged. Whether a particular file type or record has its own legal handling rules is a question for your counsel, and the scope names those files so they are kept out until that is settled.

Choosing Where The Index Lives

Four homes and where each one stops

Home	Good for	Where it stops	Who holds access
Your document platform's search	Teams already on one platform	Limited control over answer format	The platform, under your account
Hosted index in your account	Shared folders across tools	Needs permission sync set up well	You, with the owner as admin
Private cloud index	Stricter data rules	More setup and upkeep	You, in accounts you control
Self-hosted index	Full control of storage	Needs someone to run the server	You, on your own hardware

Closest Work I Can Show

Closest work and what it was not

I have not yet built a client retrieval system that I can show you. The nearest working systems are my own operation, which files every automated step in a log you can open, and the gated pipelines on the work pages. Those show the citation and logging discipline a knowledge base needs.

They do not show a client's retrieval results, and I do not claim any. Before I quote, I ask for the file list and test it against a sample of real questions, so you see the answer quality on your own material.

I built and run giostarwellness.com for a regenerative medicine and wellness clinic in Henderson: every service page, online booking, financing and a blog. A website lead is tracked end to end, from the form to a booked consult to an active patient, with no manual steps. I also built its live brand hub, so every page, post and print piece pulls the same colours, type and rules.

After going back and forth on whether to bring in outside help, we ended up working with Justin for some AI consulting on how to structure our operations. He laid out a clear plan, didn't overcomplicate it, and we've been running smoother since. Good fit for a service business. He knows Las Vegas and he knows this stuff.

★★★★★
Justin joined our team a few months before opening to replace a marketing agency that wasn’t performing. He stepped up fast. Within weeks he launched a fully redesigned website with new brand guidelines, built and delivered our marketing plan and AI strategy, and helped implement our system architecture so we could open on time. Since then, he’s made several critical enhancements to the site that helped us generate revenue in our first month. His engagement was supposed to end at opening, but he became such an integral part of our leadership team that we kept him on to help evolve our marketing and tech strategy as we grow. He’s easy to work with, pushes back when it matters, and moves easily between strategy, delivery, and operations depending on what’s needed. If you’re looking for a deeply experienced, knowledgeable, and dedicated marketing, AI, or technology consultant, I highly recommend Justin Harris AI Consulting.

RAG Development Cost

What sets the price

I quote a fixed price for a written scope after I have seen the file list and the permission model. A clean set of current folders is a different job from years of mixed drives with unclear ownership, so a flat price would be wrong for both.

Accuracy Testing

Questions the staff really ask

The test set is built from questions your staff actually asked in the past month, plus the ones that caused trouble. Each answer is checked for two things: whether the cited passage says what the answer claims, and whether the answer stops when the files do not cover the question. A system that answers everything fails this test.

Keeping The Index Current

Files added, changed and removed

A knowledge base decays when its files move on and the index does not. The index refreshes on a schedule the owner approves, and every refresh writes a short log of what was added, changed or removed, so a stale answer can be traced to a stale file.

Who Builds The Knowledge Base

One builder from files to answers

I am Justin Harris. I have built websites and run digital marketing for Las Vegas businesses for fourteen years, and I build the permission model and the citation rules myself. You talk to the person who maps your folders, not to a handoff team.
