Best AI-powered financial assistant (2026): 6 tools compared

Which is the best AI-powered financial assistant right now? On paper, ChatGPT’s Finances feature is the most complete consumer product: it links bank, card and brokerage accounts through Plaid, builds a dashboard, and answers questions from your own transactions. Evergreen.ai is the most ambitious on planning and tax math and is free during its beta. Richify is the only one built around manual entry, which makes it the natural pick for people who will not connect a bank.

How we checked this

We compared six assistants, ChatGPT (Finances feature), Claude (connectors), Gemini (Google’s own budgeting guidance), Evergreen.ai, Richify and Monarch, using their official product pages, help-center articles, launch posts and pricing pages, opened between September 21 and September 24, 2026. Every claim below links to the page it came from. This comparison is based on official documentation; the section on what people who used them found summarizes published hands-on reviews by others, each linked. Facts checked on September 25, 2026.

The six at a glance

Two things separate these tools more than model quality: how they get your data in, and what they are allowed to do with it. The table is built from the vendors’ own documents.

Which is built for budgeting, which for subscriptions, which for cross-currency questions

For budgeting from live data, two tools ship purpose-built dashboards. ChatGPT’s Finances page shows “Spend by category”, “Spend this month” against recent trends, “Upcoming payments”, “Bills” and “Net worth” widgets, and lets you ask “Am I on pace to stay within my grocery budget?” in chat (OpenAI Help). Monarch’s site describes flexible category budgets, a searchable list of every transaction, and a “reviewed” flag for spotting anything unexpected (Monarch). Monarch is a budgeting app first, so check whether it answers the free-form questions you care about or mainly shows charts.

For subscriptions, ChatGPT and Monarch both claim automatic detection. ChatGPT lists a “Subscriptions” widget with “amounts, cadence, and next charge dates” and suggests the prompt “Do I have any duplicate payments?” (OpenAI Help). Monarch says it “automatically detects your recurring subscriptions” so you can “spot forgotten charges” (Monarch). Gemini’s approach is different in kind: Google’s own guide suggests asking Gemini in the Gmail side panel to identify services billing you automatically, which finds subscriptions by reading receipts, not transactions (Google blog). That can work well for a person whose receipts land in Gmail and badly for anyone else.

For cross-currency questions, Richify is the only one of the six whose documentation makes multi-currency a headline feature: a multi-currency net worth calculator and localized tax and retirement logic for eight countries (Richify). ChatGPT’s Finances feature is U.S.-only (OpenAI), and Evergreen.ai’s launch materials talk only about “all Americans” (Business Wire via Yahoo Finance). Claude and Gemini can do currency arithmetic from a CSV like any general model; check that any answer states the exchange rate it used.

Which ones need bank access and which work from a CSV

Three of the six are designed around a live bank connection. ChatGPT connects through Plaid and says “Finances works best when your accounts are connected through Plaid”, while letting you describe unsupported accounts, property or private loans in chat and save them as financial memories (OpenAI Help). Evergreen.ai links accounts through Plaid and lets you “add the rest yourself” (Evergreen.ai); FinTech Futures confirms the Plaid partnership (FinTech Futures). Monarch says it “syncs with multiple financial data providers” to reach 13,000+ institutions (Monarch).

Two work without any bank at all. Richify is manual entry “by design”, with “no Plaid, no stored credentials” (Richify). Claude has no bank feature; it reads what you upload, and its Free plan already includes file creation and code execution (Claude pricing). A CSV of transactions is the obvious input. Claude can also reach a third-party finance data service through a custom connector, which the help center says is available on Free (one connector), Pro, Max, Team and Enterprise plans, with a warning that custom connectors “haven’t been verified by Anthropic” (Claude Help). We cover which of those connectors are worth trusting in the Claude connectors guide.

Gemini sits in the middle. Google’s February 2026 guide tells readers to paste “a messy bank statement” into Gemini in Sheets and ask it to categorize spending (Google blog). That is a CSV workflow in practice.

Where each one is likely to get a number wrong, or say something it shouldn’t

What each vendor admits about error tells you where to look.

OpenAI’s help page is the most candid. It says a spending breakdown “may look inaccurate if transfers, credit card payments, reimbursements, or duplicate pending transactions are counted as spending”, that some institutions share balances but not “full transaction history, investment holdings, loan details, APRs, due dates”, and that “as always, AI can make mistakes” (OpenAI Help). The remedy it offers is to ask ChatGPT which transactions it included and reclassify them. OpenAI also publishes its own internal benchmark: GPT-5.5 Thinking, the default model in Finances, scored 79 out of 100 on a composite of expert-graded quality and accuracy; GPT-5.5 Pro scored 82.5 (OpenAI). That is a vendor-run score on vendor-chosen tasks, so we treat it as a floor for expectations, not a result.

Evergreen.ai makes the strongest structural claim: its numbers “come from tested, rules-based calculations”, and language models are used for communication rather than arithmetic (Evergreen.ai). Its CTO describes the architecture as pairing “probabilistic large language models” with “deterministic software that runs the actual calculations” (FinTech Futures). If that holds, savings plans and debt-payoff comparisons are where Evergreen should separate from the general chatbots. The risk shifts elsewhere: Evergreen is a registered investment adviser that describes itself as giving “advice”, so it may recommend where a general chatbot would hedge.

Claude and Gemini carry the ordinary risk of a general model doing arithmetic on a spreadsheet. Anthropic’s finance materials are aimed at analysts and repeatedly say the tooling is “for research and analysis, not investment advice” (Claude Academy). Richify states that it “offers AI-powered coaching and tools, not licensed financial advice” (Richify). Monarch’s help center describes an AI Assistant that answers questions about spending, cash flow and net worth from your own financial data, and says it is optional and can be turned off in Settings (Monarch Help). We kept it because it is the incumbent budgeting app these chat tools are trying to replace, and it now has an assistant of its own.

What each costs per month at the tier where the feature works

Prices below come from the vendors’ own pages.

ChatGPT. The Finances feature is “available in the U.S. to Plus and Pro users” (OpenAI Help); OpenAI’s launch post was updated on June 25, 2026 to reflect the extension from Pro to Plus (OpenAI). Plus is $20 per month, billed monthly with no annual option (OpenAI Help). The same help article notes that as of September 10, 2026 OpenAI has “temporarily” paused new sign-ups and upgrades to the $200 Pro plan; the $100 Pro plan is not affected. OpenAI’s public pricing page lists plan names and features (OpenAI pricing).

Claude. Free includes connectors and file handling; Pro is $20 billed monthly or $17 per month on an annual plan ($200 up front); Max starts at $100 (Claude pricing). For a personal-finance workflow, the practical cost is Pro plus whatever the third-party finance connector charges, which varies by provider.

Gemini. Google’s subscription page showed prices in Mexican pesos when we checked: Google AI Pro at MXN 395 per month with “4x” the free tier’s usage, and AI Plus at MXN 99 (Google). Google’s plans page shows the same tier structure (Google One). Confirm the U.S. dollar price on Google’s own page before you subscribe, and treat dollar figures quoted elsewhere with care.

Evergreen.ai. Free for anyone who registers during the public beta, through January 1, 2028, with no credit card (Evergreen.ai). Human adviser services and investment management are paid extras.

Richify. Free on iOS and Android with a message-capped assistant; Pro at $9.99 per month or $99 per year (Richify).

Monarch. A 7-day free trial and a “Core” annual plan that promo codes apply to (Monarch pricing). Richify’s comparison table lists Monarch at $14.99 per month (Richify), and a member quote on Monarch’s own pricing page mentions “$99 a year” (Monarch pricing); neither is an official price list, so confirm the price at checkout.

Which is safest for someone who will not connect a bank

If “safe” means no third party ever holds a login to your bank, two of the six qualify outright. Richify never asks for bank credentials and stores what you type (Richify). Claude with a CSV upload is the same in effect: the data you share is the file you chose, and Anthropic’s help center says connected services “process data on their own infrastructure, under their own terms” only if you add one (Claude Help). Gemini with a pasted statement in Sheets is a third option, with the caveat that the statement then lives in Google Drive.

Manual entry has a cost, and the vendors are honest about it. ChatGPT’s help page says Finances “works best” with Plaid because the dashboard widgets only appear “when ChatGPT has enough connected data to generate them” (OpenAI Help). Richify’s own pitch is that you get insight “without losing” the AI by entering assets yourself, but that is an assets-and-liabilities model rather than a transaction feed, so a subscription audit will depend on how much you are willing to type.

For readers who do decide to link, the controls differ. ChatGPT lets you disconnect from Settings and says synced data “will be deleted from OpenAI’s systems within 30 days”, while temporary chats never touch connected accounts (OpenAI Help). Evergreen.ai says financial information “is not used to train public AI models and is not sold” (Evergreen.ai). ChatGPT’s finance conversations follow whatever model-training setting you already chose (OpenAI), so check it before connecting. The revoke steps for ChatGPT are walked through in how to connect your bank to ChatGPT via Plaid.

Tool by tool

ChatGPT Finances

OpenAI released the feature as a preview for U.S. Pro users on May 15, 2026 and extended it to Plus on June 25 (OpenAI). It connects through Plaid to “more than 12,000” institutions, with Intuit support described as “coming soon” at launch. Once synced, you can ask questions anywhere in ChatGPT by typing “/finances” or “@finances”, and answers “may cite the relevant source data so you can review where the answer came from” (OpenAI Help). Conversations default to GPT-5.5 Thinking. The launch post includes a worked example, a savings plan built from four months of categorized spending, that shows the format: category caps with an estimated monthly saving per lever (OpenAI). The main limits are geography (U.S. only) and scope: it can read balances, transactions, investments and liabilities but “cannot see full account numbers or make any changes to your accounts”.

Claude with connectors

Claude has no consumer finance product. What it has is a general connector system: directory connectors plus custom connectors to any remote MCP server, configurable per tool as “Always allow, Needs approval, or Blocked” on Team and Enterprise plans (Claude Help). Anthropic’s own finance connectors, FactSet, S&P Capital IQ, MSCI, PitchBook, Morningstar, LSEG, Daloopa and a Moody’s MCP app, are sold to firms through Claude for Financial Services, which “includes Claude for Enterprise” and requires licenses with each data provider (Claude Academy, Anthropic). For a household, the realistic path is a CSV upload or a third-party personal-finance MCP server.

Gemini

Google’s published guidance for personal budgeting is a list of prompts rather than a product: plan big purchases in the Gemini app, generate a budget template in Sheets, “automatically categorize spending” from a pasted statement, write formulas, “spot leaks in your budget”, and ask Gemini in Gmail to find “zombie subscriptions” (Google blog). That makes Gemini the most flexible of the six for someone who already lives in Google Workspace and the least structured for someone who wants a dashboard. The subscription page lists Free, AI Plus, AI Pro and AI Ultra tiers and says the Gemini app’s usage limits reset every five hours up to a weekly cap (Google).

Evergreen.ai

Evergreen.ai went live on September 21, 2026, founded by Bill Harris, formerly CEO of PayPal and Intuit and founding CEO of Personal Capital (Business Wire via Yahoo Finance). The announcement lists the calculation tools: short-term cash flow and long-term retirement projections, equity compensation (options, RSUs, QSBS), net worth with linked accounts, mortgage and rent-versus-buy, retirement account and Roth conversion comparisons, college savings, and tax strategies including tax-loss harvesting and charitable giving. The company is a registered investment adviser (FinTech Futures), which is unusual in this group and matters for advice: an RIA can legally give individualized advice where a chatbot should hedge. Its site labels every example as “illustrative” and repeats that “AI can make mistakes” (Evergreen.ai). The gap is the transaction side: the materials emphasize planning over category-level spending, so category budgets, subscription audits and duplicate-charge checks are where it looks thinnest.

Richify

Richify describes itself as “an AI agent team”: a coordinator called Felix and seven named specialists covering a financial health score, teaching, long-term frameworks, mortgages, money behavior, life events and what-if scenarios (Richify). It tracks assets and liabilities you enter, including stocks, crypto, real estate and retirement accounts, and claims 40,000+ users and $1B+ tracked. Its comparison page ranks itself first among six apps, says so openly, and lists competitors’ prices; we treat it as a vendor document (Richify). The honest framing is that Richify is a net-worth and planning coach with a chat interface, not a transaction tool, so it suits net-worth and debt-payoff questions better than subscription audits or duplicate-charge checks, unless you enter every recurring charge by hand.

Monarch

Monarch is the control group: a subscription budgeting app with account aggregation across 13,000+ institutions, automatic categorization, recurring-charge detection, reports, goals and a shared household view at no extra cost (Monarch). Its pricing page argues for a paid model on the grounds that it never sells financial data and runs no ads (Monarch pricing). Monarch’s help center describes an AI Assistant, opened from the sparkle icon in the sidebar, that answers questions such as “What are all the subscriptions I pay for currently?” using “your actual financial data”, alongside AI-generated insights and a weekly recap (Monarch Help). Its strength on spending categories, subscriptions and duplicate charges is structural: those are the tasks a good aggregator has done for years without a language model.

What people who used it found

The comparison above rests on vendor documents. The accounts below come from writers who used the products with their own accounts or data, summarized with links so you can read them in full.

ChatGPT Finances. In a TechRadar piece published July 1, 2026, Eric Hal Schwartz connected his accounts and asked ChatGPT what he spends on eating out, which subscriptions he pays for and what had changed in his spending that month. He reports that it gathered his recurring streaming charges into one summary and flagged a run of gift purchases as unusual against his recent history, while stressing that it does not decide anything for you or replace a budgeting app. In a follow-up on August 25, 2026, he says the first review turned up two forgotten subscriptions, an $11.99 streaming add-on and a $9.99 music app, which together covered his $20 Plus fee, and adds that he would not “blindly trust ChatGPT with finances” on bigger decisions.

Claude. Josh Dubowsky, writing on Medium on June 8, 2026, describes cancelling a $199-a-year budgeting app, exporting his bank transactions to CSV with account numbers stripped, and running four prompts in Claude each month. He says the recurring-charge prompt surfaced $312 a year in forgotten subscriptions and that eating out was the category he had been underestimating; he also says the approach does not suit complex finances such as businesses or investments. Developer Kirill Markin, on his personal site (March 5, 2026, updated April 11), gives a Claude agent his weekly bank exports as CSV, PDF or screenshots across EUR, USD and RUB accounts. He reports that it categorizes and checks balances, cutting his weekly bookkeeping from about an hour to about ten minutes, and that it asks when unsure, for example where a 120-euro furniture-store charge belongs.

Gemini. In TechRadar on June 4, 2026, Krishi Chowdhary used Gemini in Google Sheets to build a weekly budget: a budgeted-versus-actual table fed by a separate log of expenses. He reports that the first SUMIF formulas Gemini wrote did not update on their own and needed a more specific prompt, after which the tracker updated as expenses were added and color-coded overspending. Like Google’s own guide, his setup starts from data entered into Sheets, not from a bank connection.

Monarch. Andy Hill of Marriage Kids and Money has used Monarch daily with his wife since November 2022 across 23 connected accounts; his review was published August 14, 2026 and updated September 22. He uses the AI assistant now and then for one-off questions, such as whether a Costco membership upgrade paid off and how much his son’s instrument rentals had cost (about $550), and says it “quietly saves time without getting in the way.” He still reviews Amazon, Costco and Target transactions by hand, says Monarch is less focused on cutting subscriptions than Rocket Money, and lists the Core plan at $99.99 a year.

These first-hand accounts match the vendors’ documentation on the basics: ChatGPT’s subscription and change-in-spending answers behaved as OpenAI’s help page describes, and the Claude and Gemini workflows all began with a file or a sheet rather than a bank link. The one place they add to the official record is Monarch: Hill’s review, and Monarch’s own help center (Monarch Help, updated February 20, 2026), describe an AI assistant that answers questions about spending, cash flow and net worth from your data.

Where it goes wrong

The common failure across every tool that reads transactions is categorization, not reasoning. OpenAI lists transfers, credit-card payments, reimbursements and duplicate pending transactions as the usual culprits when a spending total looks wrong (OpenAI Help); the same four items break any budgeting app.

The second failure is silent scope. An institution can connect and still withhold transaction history or loan APRs, and the tool will answer as if it had everything (OpenAI Help). Ask what data the answer used before you trust a number.

The third is advice creep. Every vendor here says it is not your adviser, in different words, and Evergreen is the exception because it is an adviser. If a tool tells you to move retirement contributions, refinance or sell a position, that is the moment to consult a licensed professional rather than the moment to act; none of these products can see your full tax picture, and the free ones in particular are not accountable for the outcome.

The fourth is connector trust. Claude’s help center warns that custom connectors “haven’t been verified by Anthropic” and asks you to “review authentication permissions carefully” (Claude Help). A community-built server that asks for your bank app’s password and two-factor secret is a bigger risk than any answer it produces.
