One AI Stack Beats Tool Sprawl

If your Highland Park law firm, Winnetka wealth practice, or Lake Forest insurance agency has added a new AI subscription every quarter this year, you already have the symptom. The fix is not another tool. It is picking one AI stack and retiring the rest.

The fastest way for a North Shore professional services firm to stop AI tool sprawl is to standardize on one general-purpose platform, such as Claude or ChatGPT, as the default for drafting, research, and client communication, then add a narrow point tool only where that core platform genuinely cannot do the job.

What Is AI Tool Sprawl, and What Is It Costing Your Firm?

AI tool sprawl is the accumulation of separate AI subscriptions across a firm, each covering one narrow task, with no single platform serving as the default anyone reaches for first. A partner drafts in ChatGPT. An associate summarizes depositions in a transcription app. The client services team drafts renewal letters in a third tool nobody else at the firm has access to.

None of that is exotic. It is what happens when every team member picks their own tool the week they first need one, and nobody circles back to consolidate. Shadow IT, the long-standing term for software staff adopt without a formal review, describes the same pattern now playing out with AI apps instead of spreadsheets and file-sharing tools.

The cost shows up in three places. First, licensing: five tools at roughly $20 a month each cost more than one shared plan built for a small team. Second, data governance: every point tool is another vendor holding your client files, another data-processing agreement someone should have actually read. Third, and most expensive, adoption: staff who juggle three logins for one job quietly stop using all three and go back to doing the work by hand. If your firm wants a plain read on where it stands today, Bace's AI readiness quiz takes ten minutes and flags the gaps.

How Do You Choose a Single AI Stack for Your Firm?

Start with an audit, not a purchase. List every AI tool anyone at the firm currently pays for or runs on a free tier, who uses it, and what task it actually does. Most firms find the list is longer than any partner expected.

Next, pick the anchor platform: the one general-purpose tool that becomes the default for drafting, research, summarizing, and client communication across the firm. Anthropic's Claude and OpenAI's ChatGPT both work as an anchor. The deciding factor for most North Shore firms is which one plugs in cleanly to the software you already run, whether that is Applied Epic, Clio, or Wealthbox, and which one your compliance team is comfortable putting client data through. Judge the two on real differences: context window size for handling a full policy file or case record in one pass, and how clearly the vendor documents data handling for business accounts. Do not judge them on brand familiarity alone.

Then set a retirement rule. Give every overlapping point tool a 90-day sunset date the day you sign the anchor platform's business plan. Without a deadline, the old tools just sit there, still billed, still a second login nobody remembers to cancel. This is also where Bace's AI consulting engagements tend to add the most value: not picking the tool, but running the audit and the migration so consolidation actually happens on a calendar instead of a someday list.

Where One Stack Beats a Pile of Point Tools

A single anchor platform is not automatically the right call for every task. Specialized tools still earn their place when they do something narrow that a general assistant cannot, such as a dedicated e-discovery platform for litigation or a purpose-built claims-scoring tool for underwriting. The test is whether the specialized tool does something a general platform truly cannot, not just something it does slightly differently.

This is not a theoretical concern. McKinsey's recurring survey on the state of AI has tracked adoption climbing at firms for several years running, with generative AI use moving from experiment to daily habit at the firms that stick with it. The firms falling behind are rarely the ones with too few tools. They are the ones where nobody uses any of the many tools consistently, because no single tool is the obvious first choice. Pull a few recent client wins from Bace's case studies to see what a consolidated setup looks like in practice for a North Shore firm.

Pick your anchor platform this quarter, put a 90-day sunset date on everything that overlaps with it, and watch Anthropic's and OpenAI's next enterprise releases before you add a single new subscription. Most of what a fourth AI tool promises is already sitting inside the one you have not fully turned on yet.

If you want a second opinion on which tools in your current stack are worth keeping, a free 30-minute AI audit with Bace Agency covers exactly that. No obligation, and the output is a one-page plan your team can act on this quarter.
