An answer that reaches a client deserves more than one AI behind it.
Deepest sends your question to several top AI models at once and shows you exactly where they disagree. When your explanation carries fiduciary weight, the disagreement is the review layer a single chatbot never gives you.

Watch three models stress-test the same assumption
One planning assumption, three top models, three different views of what breaks it first. Where they split is where the client conversation should go.
Simulated demo for illustration. Actual responses are more detailed and personalized.
Why one AI is not enough when you owe a fiduciary duty
A single chatbot gives you one fluent answer with no way to tell the solid from the subtly wrong. In this profession, subtly wrong reaches a client with your name on it.
Confidently wrong reaches the client with your name on it
An AI explanation of Roth conversion rules or RSU tax treatment that is subtly wrong does not look wrong; it looks polished. If a client acts on it, the error is yours: your E&O exposure, your compliance file, your relationship. When several models answer the same question, the wrong detail stands out because the others do not repeat it.
One answer hides the assumptions it made
Every planning answer rests on assumptions about horizon, tax treatment, and how clients actually spend. A single model bakes its assumptions in silently, so the answer looks more settled than it is. Three models surface three different sets of assumptions, and the differences show you exactly what the plan is sensitive to before the client asks.
Different models, different strengths
One model is strongest on long documents, another on careful tax mechanics, another on explaining things plainly. Subscribing to one vendor gives you one analyst. Deepest gives you the panel, in one place, for less than two separate subscriptions.
How financial advisors use Deepest
Three ways to combine the models, mapped to how advisory work actually gets checked.
Compare · where the models agree and disagree
Compare: the built-in second opinion
Ask once and every model answers side by side, with an automatic breakdown of where they agree and where they split. Use it on anything you are about to explain to a client: conversion rules, tax treatment, how a product document actually works. Agreement across models is not proof, but disagreement is a precise map of what to verify against primary sources before it goes out under your name.

Compare
Two of three explain it the same way. The odd one out is what you verify before the client call.
Synthesis · one combined best answer
Synthesis: one letter from the strongest drafts
For client letters and market commentary you rarely want three drafts; you want the best one. Synthesis has the models write independently, then combines the clearest explanation and cleanest language into a single draft. Quarterly letters, meeting follow-ups, and plain-English explainers arrive already cross-pollinated instead of reflecting one model's habits, and they still go through your compliance review like everything else.

One letter, assembled from the strongest sections of each draft.
Debate · models argue and converge
Debate: stress-test the assumption before the market does
Debate makes the models argue against each other and converge over rounds. Put a planning assumption in (a withdrawal rate, a horizon, a tax expectation) and watch what survives contact. The objections that emerge are a preview of the questions a skeptical client or a bad market year will ask, and the assumption left standing is the one worth building the review around.

What advisory work looks like with a model panel
Four places advisors put Deepest to work on day one. Each prompt is copyable as written.
Client letters and market commentary
Draft quarterly letters, meeting follow-ups, and market updates that read calmly and survive compliance review. Synthesis merges the models' drafts into one that is clearer and less templated than any single model produces.
Try this prompt
Draft a quarterly client letter from these notes. Explain what happened in markets this quarter in plain English, calm tone, no predictions and no recommendations, under 500 words: [paste your bullet points]
Stress-testing planning assumptions
Withdrawal rates, horizons, tax expectations, spending patterns. Several models attack the same assumption from independent angles, and the union of their objections is the review checklist for the plan.
Try this prompt
Stress-test this assumption from a client's retirement plan. List what most threatens it in ranked order, the conditions under which it fails, and what I should examine before presenting it: [paste the assumption]
Explaining complex topics at the right level
Roth conversions, RSU tax treatment, Medicare IRMAA cliffs. Get an explanation pitched at a smart non-expert, cross-checked by other models so a subtly wrong detail does not reach the client sounding authoritative.
Try this prompt
Explain a Roth conversion to a 58-year-old client considering one before RMDs begin: what it is, the tax mechanics, and the trade-offs in both directions, at the level of a smart non-expert. Do not recommend whether to do it.
Summarizing regulatory and product documents
Prospectuses, regulatory updates, plan documents. Each model summarizes independently, so an omission or misreading in one summary shows up as disagreement instead of slipping through.
Try this prompt
Summarize this prospectus section: the fee structure, every risk it discloses, and anything unusual compared to a typical prospectus. Quote the exact language for anything important: [paste the section]

Confidentiality
Built for work you cannot leak
Conversations are encrypted in transit and at rest, are never used to train models, and you can export or permanently delete everything at any time. Prompts go to model providers through enterprise APIs, not consumer chatbots. Follow your firm's AI and books-and-records policies, and anonymize client identifiers where your rules require it; the workflow works exactly the same.
