Questions

What clients usually ask first. Search finds the rest.

Do we need a technical team to work with you?

No. You work in plain English and Caleb does the setup. If you have an IT provider, he brings them in before anything is installed on a company computer.

Who will we work with?

Caleb, every time. Arbren is one person: whoever you talk to on the first call does the setup, the build and the follow-up.

Where should a business like ours start?

With one repetitive task that eats a few hours a week: routine email, meeting notes, quotes, document summaries. Give a small group a business-grade tool, set simple rules for what information can go in, and measure the time saved over a month. Keep what works and drop what does not. The industry guide shows the starting point we would pick for yours.

Which is best: Claude, ChatGPT or Copilot?

We recommend Claude first: it is the strongest at long documents, careful writing and analysis, and it includes Claude Code, which works through folders of your documents. ChatGPT Business is a strong second, with the broadest toolbox including images and voice. Microsoft Copilot is the easiest choice for an office that lives in Outlook and Teams. The Which AI guide has prices, usage limits and a plan finder.

Is the free version good enough?

For trying things out on your own, yes. For company or client information, no. Business plans give you an admin console, let you remove access when someone leaves, and come with contract terms that keep your data out of model training. A business seat usually costs about the same as a personal subscription.

Can we put client or patient information in?

In a business plan like Claude Team or ChatGPT Business: client files, financials, policies and contracts, yes. Full SSNs, bank, account and card numbers, and health information stay out; use the last four or a client code. Patient information needs an Enterprise plan with a signed business associate agreement, and tax return information falls under Section 7216. Caleb writes down what can go where so your team never has to guess.

Are there state AI laws we need to follow?

Usually not for an ordinary business using these tools. Minnesota and Iowa, the states we cover in depth, have no general AI law for that; Iowa's 2026 chatbot law, which starts July 1, 2027, targets companion-style chatbots and excludes business customer-service and internal tools. A few states, like Colorado and California, go further, and we check yours. What always applies are the rules you already know: privacy, healthcare, insurance, banking, open records and professional ethics. Announce an AI notetaker on calls, since some states require everyone's consent to record. Your attorney confirms the specifics.

How accurate is it? Can we trust what it says?

AI is very good at drafting, summarizing and organizing, and it still gets specific facts, figures and citations wrong, especially ones you did not give it. Give it your source material, ask it to show where answers come from, and have a person check anything that leaves the building. Your business stays responsible for what it sends.

Do we need an AI policy?

Yes, and it can be two pages. Your team is probably already using AI on personal accounts, and a policy turns that into clear rules: which tools are approved, what information is off limits, who reviews anything that goes to a customer, and who to ask. We write it with you and train people on it.

What do the AI tools cost?

A business AI seat runs $20 to $25 per person per month, and you may already have some AI included in Microsoft 365 or Google Workspace. The bigger investment is setup and training time, so we start with a small pilot and measure the return before you scale. At $20 a seat and $45 an hour of staff time, a seat pays for itself if it saves about 6 minutes a week; the Which AI guide has a calculator for your numbers. The Stacks guide prices three complete setups for any team size.
