The Honest Framework First
Before I give you the tool list, here’s the framework I use to decide when AI is enough:
AI is enough when:
- You need information, research, or a first draft
- The stakes of being wrong are low-to-medium
- You need something at an odd hour
- You need to understand something well enough to make your own decision
AI is NOT enough when:
- Legal documents need to hold up in court
- Medical symptoms need a diagnosis
- Tax situations involve audits or significant complexity
- Mental health crises need immediate human support
With that said — let’s get into it.
1. Financial Advisor → AI + One Annual Human Check-In
What I used to pay: $200/month ($2,400/year)
What I pay now: $0 (ChatGPT Plus: $20/month, which I use for everything)
My financial advisor was good. But 90% of our meetings were me asking questions I could have Googled, and him explaining concepts at a speed calibrated to keep me comfortable rather than to actually educate me.
Now I ask Claude or ChatGPT things like:
- “Explain the difference between a Roth conversion ladder and a backdoor Roth, and which makes sense for someone in my income bracket”
- “What are the tax implications of selling RSUs in the same year I max my 401(k)?”
- “Build me a basic net worth tracker spreadsheet with formulas for asset allocation by age”
The AI explains it like a knowledgeable friend who doesn’t bill by the hour. Then once a year, I pay a fee-only fiduciary advisor $300 for a two-hour review to sanity-check my decisions. Total annual cost: $300 vs. $2,400.
What AI can’t replace: Active portfolio management if you have complex holdings, estate planning across multiple states, or decisions involving business equity.
2. Attorney (General Retainer) → AI for Research, Lawyer for Signatures
What I used to pay: $150/month retainer
What I pay now: $0 monthly, ~$200/year for actual documents
My retainer was mostly for “peace of mind” and occasional contract reviews. In three years, I used it maybe four times for actual substantive work.
Now I use AI to:
- Draft NDAs and simple service agreements (then have an attorney review before signing anything over $5K)
- Understand my rights as a tenant, employee, or consumer before I negotiate anything
- Research what questions to ask before consulting a lawyer — so the actual consult is 20 minutes instead of 90
Tool I use: Claude or ChatGPT with a prompt like: “I’m a [state] resident. My landlord is refusing to return my security deposit citing [reason]. What are my legal options and what documentation do I need?”
What AI can’t replace: Actual legal representation, filing documents, anything that requires a licensed attorney’s signature.
3. Nutritionist → AI Meal Planning With Annual Bloodwork Review
What I used to pay: $300/month
What I pay now: $9/month (Cronometer premium) + annual bloodwork ($150)
My nutritionist was phenomenal for the first three months — she changed how I think about food. But month seven of paying $300 for “keep doing what you’re doing” was the turning point.
Now I use AI for:
- Weekly meal planning based on my macros, preferences, and what’s in my fridge
- Understanding nutrition research (“What does the evidence actually say about seed oils?”)
- Adjusting my eating protocol around training blocks or travel
The workflow: I get bloodwork done annually (often covered by insurance). I share the results with Claude and ask it to flag anything worth discussing with my doctor. It explains what ferritin, homocysteine, and ApoB actually mean without the 15-minute “let me explain what blood is” preamble.
What AI can’t replace: Eating disorder treatment, chronic disease management requiring medical nutrition therapy, highly individualized protocols requiring ongoing labs.
4. Business Coach → AI Thought Partner + Peer Group
What I used to pay: $500/month
What I pay now: $0 (peer group is free)
This one surprised me the most. I was skeptical AI could replace the challenge and accountability of a good coach.
It can’t — entirely. But here’s what it can do:
I use Claude as a pre-thinking tool. Before a hard conversation with my boss, a major strategic decision, or a quarterly review, I explain the situation to Claude and ask:
- “What am I not seeing here?”
- “What’s the argument against my current plan?”
- “Play devil’s advocate on this decision”
- “What would a McKinsey partner say is missing from this analysis?”
It consistently surfaces blind spots I’d have paid a coach $500 to find. The remaining accountability gap I filled with a free peer group of five people at similar career stages who meet monthly on Zoom.
What AI can’t replace: Deep behavioral change work, executive presence coaching, leadership development that requires human observation over time.
5. Accountant (Tax Prep) → AI + TurboTax + One CPA Call
What I used to pay: $200/month prorated ($2,400/year for tax season + ongoing)
What I pay now: $89 (TurboTax Self-Employed) + $150 one CPA call for complex questions
My situation: W-2 income, one rental property, freelance income, RSUs, HSA, and retirement accounts. Not simple — but not the kind of complexity that requires a $2,400/year CPA relationship.
I use AI to:
- Understand what deductions I might be missing (“I work from home part-time as a W-2 employee and also have self-employment income. What home office deduction rules apply to my situation?”)
- Prepare for my CPA call so I ask precise questions instead of rambling ones
- Understand the implications of tax decisions before I make them (Roth vs. traditional, timing of asset sales, etc.)
What AI can’t replace: IRS audit representation, complex multi-state filings, business entity structuring, anything that requires a CPA’s license on the line.
6. Personal Trainer → AI Programming + One In-Person Form Check
What I used to pay: $480/month (3x/week sessions)
What I pay now: $19/month (training app) + $150/quarter (single in-person session)
I trained with my coach for 18 months. In that time, I learned to squat, deadlift, and press with good form. After that, most sessions were him telling me what to do while I did it.
Now I use AI to:
- Build my own training blocks (ask Claude for a 12-week strength program for an intermediate lifter with specific constraints)
- Adjust programming when something hurts or life disrupts the schedule
- Understand the principles behind programming decisions so I can adapt intelligently
Quarterly, I book one session with a coach for a form check and programming review. Cost: $150/quarter vs. $480/month.
What AI can’t replace: Real-time form correction on complex movements, sport-specific coaching, rehabilitation after injury.
7. Executive Assistant → AI Workflows + Automation
What I used to pay: $1,200/month (20 hours part-time at $60/hr)
What I pay now: ~$30/month (tools)
This is where AI has been most transformative. My EA handled:
- Email triage and drafting
- Calendar management
- Research and briefing docs
- Travel booking
- Document formatting
Claude handles the first drafts of almost every email I write. I describe the situation and the tone, it drafts, I edit in 30 seconds. Research briefings I used to pay $120 for (2 hours of research) now take me 20 minutes with AI assistance. I use Calendly for scheduling (free tier). I book my own travel in 10 minutes using AI to compare options.
What AI can’t replace: Phone calls requiring human judgment, complex relationship management, tasks requiring physical presence.
What I Actually Spend Now
| Former expense | Old cost | New cost |
|—|—|—|
| Financial advisor | $200/mo | $25/mo (one annual consult prorated) |
| Attorney retainer | $150/mo | $17/mo (annual doc review prorated) |
| Nutritionist | $300/mo | $9/mo + $12.50 bloodwork prorated |
| Business coach | $500/mo | $0 |
| Accountant | $200/mo | $19/mo |
| Personal trainer | $480/mo | $56/mo |
| Executive assistant | $1,200/mo | $30/mo |
| Total | $3,030/mo | $168.50/mo |
Monthly savings: $2,861.50
Annual savings: $34,338
That’s not a rounding error. That’s a salary.
The Tools I Actually Use
- Claude (Anthropic) — reasoning, research, writing, strategy
- ChatGPT (OpenAI) — day-to-day questions, quick lookups
- Cronometer — nutrition tracking with micronutrient data
- Notion AI — document organization and summarization
- Calendly — scheduling automation
- YNAB — personal finance tracking (AI-assisted budgeting review)
Most of what I do runs on one $20/month ChatGPT Plus subscription or the free tier of Claude.
The Part Nobody Talks About
The financial savings are real. But the bigger shift was epistemic.
I stopped being dependent on professionals to translate the world for me. I started understanding why — why the nutritional recommendation, why the legal structure, why the financial allocation. That understanding compounds. Every question I ask AI, I retain more than I would from a 30-minute appointment where I was too intimidated to ask follow-ups.
AI made me a more informed person, which made me a more informed client on the occasions I do hire professionals.
That’s the actual return on investment.
