Yes. Sort of. Here's an honest step-by-step attempt — and exactly where it breaks down.
You can do everything on this page perfectly. Every step. Four to eight hours of work. Every month.
That answer could mean the difference between retiring five years earlier or five years later. Richer or poorer. On your terms or on someone else's.
The peer data — real performance results from real investors who took the same risk you did — simply doesn't exist anywhere. No AI has it. No website has it. It has never been collected.
WiseMint is the only place it exists. And it grows more valuable with every investor who joins.
What you need before AI can help at all — and it is more than just balances
To calculate portfolio performance properly, you need detailed end-of-month statements — not just account balances. Each statement must include every buy, sell, distribution, deposit, and withdrawal for that month. For a 2-year analysis: 24 detailed statements per account. Three accounts = 72 PDFs to locate, download, and upload.
Here is the complication most people do not anticipate: these statements are not clean data files. They are multi-page PDFs packed with pages of templated regulatory and legal disclosures — terms of service, tax notices, compliance language. All of that text must pass through the AI before it reaches the transaction data buried inside. On a free AI account with a limited context window, this alone can cause the extraction to fail before it starts.
Why niche or regional brokerages create a wall the AI may not be able to climb
Major brokerages — Fidelity, Schwab, Vanguard — use statement formats that AI has likely encountered in its training data. Extraction is imperfect but usually workable. The problem arrives when you hold accounts at a regional broker, a specialty custodian, or a smaller institution whose statement layout is entirely unfamiliar to the AI.
Why the DIY workload gets heavier — not lighter — every single month
You have spent hours uploading 24 months of statements and established a baseline. Next month you return with one new statement.
The problem isn't that AI gets it wrong — it's that you don't know what to ask for
You now have a transaction history and ask for your return. You get a percentage and feel satisfied. AI will give you a technically correct answer to the question you asked. The problem is that most investors don't know there are two fundamentally different return methods — and only one of them measures what you actually want to know.
Risk-adjusted return — and why the risk-free rate AI picks is almost certainly wrong
11.3% is contextless without risk adjustment. The Sharpe ratio tells you how much return you earned per unit of risk taken. A high return achieved through extreme volatility is far less impressive than the same return earned steadily. But calculating Sharpe correctly requires more than just dividing return by standard deviation — the risk-free rate used as the baseline has to be right, and it has to match the actual period being measured.
This is where almost everyone goes wrong — including some advisors
Your return needs a comparator. Most investors default to the S&P 500. For any diversified portfolio, this is the wrong benchmark. The harder problem is correctly mapping your asset allocation to the specific index values that actually track what you hold — and keeping that mapping accurate as your portfolio changes over time.
Three categories of positions that produce silently wrong results — and you will never know
Even if you have extracted your transactions perfectly and calculated TWR correctly, there is a category of complexity that sits entirely outside what AI can handle — not because AI is poorly designed, but because the underlying data simply does not exist in any source it can access.
Eight steps. Hours of effort. A TWR calculated correctly. A Sharpe ratio with the right risk-free rate. A custom benchmark properly mapped. Options handled. FX converted at the right rates.
And yet you still cannot answer this:
A number without peer context is not an answer. It is a guess dressed up as a fact. Institutional investors have always had this context. Retail investors never have.
Until now.
This is not a missing feature. It is a missing dataset — and it cannot be built any other way.
Beating your benchmark tells you one thing. Knowing how you compare to real investors who selected the same benchmark — or one extremely similar to yours — tells you whether you are skilled or whether you are simply riding conditions that everyone in your risk category rode. That comparison is the difference between a number and an answer.
What a professional-grade portfolio performance report actually requires — and how each approach stacks up.

| Sharpe ratio (auditable, repeatable) | ✗ Unauditable estimate | ✓ Documented methodology |
| Benchmark correctly mapped to your chosen target | ✗ Manual index guesswork | ✓ Correctly mapped & dynamic |
| Peer comparison vs. investors with matching benchmark | ✗ Impossible | ✓ Industry first |
| Monthly effort over time | ✗ Grows each month | ✓ 5 min setup, done |
| Simple letter grade (A–F report card) | ✗ No | ✓ Yes |
DIY with AI gets you a number. WiseMint gives you the context that makes the number mean something — automatically, every month.
After all that effort — and more every month — the DIY route still cannot answer the one question that matters: "Is my portfolio performing well for the risk I'm taking, compared to other real investors who chose the same benchmark I did?"
That answer exists in WiseMint. It is $30 a month. Completely independent — no advisor, no product to sell you, no conflict of interest. And unlike AI, it remembers everything from last month. Your results are delivered as a report card — A, B, C, D, or F. No jargon. No spin. Just the truth about how your portfolio is performing.
