Best Chat-Based Investing Apps in 2026

Last updated June 2026

Short answer

Chat-based investing apps put a conversation first, so you ask in plain language instead of tapping through a robo-advisor’s menus. Magnifi is chat-first fund research, Origin pairs planning with investing, SoFi is adding AI coaching to a full in-house investing app, and ChatGPT is the general assistant people already use to think about money. Walnut is chat-first on the broker you already own: it connects your real brokerage and grounds the conversation in what you actually hold. There is no single best one; match the app to whether you want to research, plan, or act on your own holdings. Walnut is not an investment adviser.

Most investing apps are still tap-through: a robo-advisor asks a few questions, builds a portfolio, and runs it on autopilot while you check a dashboard. A chat-based app flips that around. The primary interface is a conversation, so you ask, explore, and direct the work in plain language. But “chat-based investing app” covers some very different things. Some are tuned for fund research, some pair planning with investing, some bolt AI coaching onto a full investing app, and a few connect to the real broker you already own. The most important difference between them is not which one talks best, it is whether the chat connects to your actual holdings or only discusses investing in the abstract. This guide covers five of them (Magnifi, Origin, SoFi, ChatGPT, and Walnut), describes each on the same fields, and is honest about which connects to your broker and where each one, including Walnut, is the wrong fit.

What a chat-based investing app is

A chat-based investing app is an app whose main interface is a conversation. Instead of navigating menus, reading filings, or learning where every setting lives, you ask a question in plain English and the app answers, screens, explains, or helps you act. The category splits into a few kinds, and the split is what this whole guide turns on:

Chat-first research apps (Magnifi). Built around chat for markets: you describe what you want and they help you screen and discover funds, ETFs, and stocks. The conversation is the product, not an add-on.
Planning-plus-investing apps (Origin). Broad money apps that link your accounts and pair financial planning with investing, with a conversational layer over the whole picture rather than deep ticker research.
Full investing apps adding AI coaching (SoFi). Traditional tap-through apps where you hold accounts, now layering chat-style coaching on top so you can ask questions alongside the usual flow.
General assistants (ChatGPT). Broad conversational models people already use to reason about investing. Powerful explainers, but with no native view of your accounts.
Chat-first on your own broker (Walnut). A chat that connects the real brokerage you already own so the conversation is grounded in what you actually hold, not a hypothetical or a separate in-house account.

A general assistant talks about investing in the abstract. A connected one talks about your holdings. Both are useful; they answer different questions.

Chat-first research and planning apps: Magnifi and Origin

These are the apps where chat genuinely is the interface, each pointed at a different job. Magnifi is built for markets and fund discovery in conversation; Origin pairs planning and budgeting with investing and links your accounts so you can ask about the whole picture.

Magnifi

A chat-first investing app built specifically for markets. You ask plain-English questions about funds, ETFs, and stocks, and it helps you screen and discover securities, with some account-connection features for context.

Best for: Plain-English fund and ETF discovery and screening, as the main way you interact with the app.
Connects to your broker? Partial (some account connection).
The catch: It skews toward fund discovery rather than deep single-company research or grounding the whole conversation in the full detail of your real positions.

Origin

A personal-finance app that pairs financial planning with investing and links your accounts, with a chat-style assistant layered on top so you can ask questions about your money instead of only reading dashboards.

Best for: People who want planning, budgeting, and investing in one place with a conversational layer over their finances.
Connects to your broker? Yes (links your financial accounts).
The catch: It is a broad money app rather than a markets-research tool, so the chat is more planning-and-overview than deep, ticker-level investing research.

These are the right call when your question matches the app: “which ETF fits this exposure” for Magnifi, “how do my plan, budget, and investments fit together” for Origin. They are the wrong call when you want deep, ticker-level research grounded in the specific broker you already trade through.

Full investing apps adding chat: SoFi

The other path to a chat-based experience is a full investing app adding AI coaching on top of its existing tap-through flow. SoFi is the clearest example: you hold accounts inside it and trade the usual way, with a newer conversational layer to ask questions.

SoFi

A full investing and banking app where you actually hold accounts, now adding newer AI coaching features so you can ask questions in plain language alongside the usual tap-through investing experience.

Best for: People who want to hold and trade inside one app and use AI coaching as a helper, not the primary interface.
Connects to your broker? In-house (you hold SoFi accounts).
The catch: Chat is an added layer on a traditional tap-through app rather than the core interface, and it is centered on SoFi’s own accounts rather than a broker you already own elsewhere.

This is the right fit when you want to hold and trade inside one app and treat chat as a helper. It is the wrong fit when chat is the point and you would rather keep the broker you already own elsewhere, with the conversation grounded in those existing holdings.

The general assistant people already use: ChatGPT

For many people, the first chat-based way they think about investing is just ChatGPT. It is genuinely strong for explaining concepts and reasoning through a decision. The catch is consistent: on its own it cannot see your brokerage or live prices, and it can state wrong figures confidently, so verify anything specific.

ChatGPT

OpenAI’s general-purpose chatbot, the one most people already use as a chat-based way to think about investing. It explains concepts, walks through scenarios, and (with browsing or finance-aware modes) pulls recent context, all in conversation.

Best for: Explaining investing concepts, working through scenarios, and drafting a plan in plain language.
Connects to your broker? No (no account view).
The catch: On its own it cannot see your brokerage or live prices and has no account view, and it can state wrong figures with confidence, so verify anything specific before you act on it.

The practical takeaway: use it to learn and to think, not as a source of truth on your actual numbers. If you want one of these models to reason over your real holdings, you need an app that connects your accounts to it. See the best AI investing chatbots for the wider chatbot field.

Chat-first on your own broker: Walnut

To be upfront, since this is our site: Walnut is the chat-first-on-your-own-broker kind, and it leads in that narrow category rather than overall. Walnut is an AI investing assistant you chat with on the broker you already own. It connects your existing brokerage through SnapTrade and lets you ask about what you actually hold, and themes you are considering, by talking through Claude, ChatGPT, or a built-in assistant.

Walnut

An AI investing assistant you chat with on the broker you already own. It connects your existing brokerage through SnapTrade and lets you ask about what you actually hold, and themes you are considering, by talking through Claude, ChatGPT, or a built-in assistant, with web search and each holding framed against the S&P 500.

Best for: Asking about your real, connected portfolio in plain language and turning research into a thematic basket.
Connects to your broker? Yes (your brokerage, read-only by default).
The catch: It is not a hands-off robo-advisor or an all-in-one bank: it sits on top of a broker you already own, leans on web and price data, and frames returns as window returns because broker feeds rarely pass cost basis.

The distinctive part is that the chat knows your real positions, frames each one against the S&P 500, and can become a thematic basket you act on at your own broker. Walnut is not a hands-off robo-advisor and not an all-in-one bank: it sits on top of a broker you already own, leans on web and price data rather than a proprietary filings corpus, and because broker feeds rarely pass cost basis it frames returns as window returns rather than realized profit and loss, and says so. It is read-only by default, every trade needs your approval, and Walnut is not an investment adviser.

Which to use for what

The fastest way to choose is to name what you are trying to do, then pick the app built for that. There is no overall number one; Walnut leads only in its own category (a chat grounded in the real broker you already own), not across the board.

You want to discover or screen funds and ETFs in chat. Magnifi is built around conversation for that lane.
You want planning, budgeting, and investing in one conversational place. Origin links your accounts and pairs planning with investing.
You want to hold and trade in one app with AI coaching as a helper. SoFi adds chat-style coaching to a full in-house investing app.
You want to learn a concept or reason through a decision. ChatGPT is the general assistant most people already use; verify any specific figures it states.
You want a chat that knows the real holdings you already own. Walnut connects your brokerage through SnapTrade and lets you research what you own through Claude or ChatGPT, framed against the S&P 500.

How to choose a chat-based investing app

Once you know whether you want to research, plan, or act, a few practical filters narrow it the rest of the way:

Is chat the interface or an add-on? Apps like Magnifi and Walnut are chat-first; others bolt a conversational layer onto a tap-through app. Decide which experience you actually want.
Does it connect to a broker you already own? Some connect only their own accounts, some none at all. If you want answers about your real holdings without moving them, that rules in a connected app like Walnut.
How does account access work? If an app connects to your money, prefer regulated aggregation, read-only-by-default access, and explicit approval for any action. Walnut uses SnapTrade and approves every trade with you.
Hands-off or hands-on? A robo-advisor runs on autopilot; a chat-first app keeps you in the loop. Pick based on how much control you want over each decision.
Cost model. Free tier, flat subscription, or paid upgrade. ChatGPT and Walnut have free tiers; verify current limits before relying on them.
Does it stay descriptive? A trustworthy investing app explains and frames trade-offs without pretending to be your adviser. Be wary of anything promising guaranteed market-beating returns.

The bottom line

There is no single best chat-based investing app, because they answer different questions. Magnifi leads for chat-first fund discovery, Origin for pairing planning with investing, SoFi for chat layered on a full in-house investing app, and ChatGPT for general explaining and reasoning. Walnut is the one whose chat is grounded in the real broker you already own: it connects your brokerage, lets you talk through Claude or ChatGPT, frames each position against the S&P 500, and can turn research into a basket you act on, while keeping you in the loop on every trade. Pick by whether you want to research, plan, or act. Walnut is not an investment adviser.

FAQ

What is a chat-based investing app?

It is an investing app where the main way you interact is a conversation, not a grid of menus and buttons. You type a question in plain language and the app answers, screens, or explains. Some, like Magnifi, are built around chat for fund research. Some, like SoFi, add AI coaching to a traditional app. And some, like Walnut, put chat first on the broker you already own. Walnut is not an investment adviser.

What is the best chat-based investing app?

There is no single best one; it depends on what you want. Magnifi leads for chat-first fund and ETF discovery, Origin for pairing planning with investing, SoFi for chat layered on a full in-house investing app, and ChatGPT for general explaining and reasoning. Walnut leads if you want a chat grounded in the real broker you already own. Match the app to whether you want to research, plan, or act on your own holdings.

How are chat-based investing apps different from robo-advisors?

A robo-advisor is mostly tap-through: you answer a risk questionnaire, it builds and auto-manages a portfolio, and you check in occasionally. A chat-based app puts a conversation first, so you ask questions and direct the work in plain language. The trade-off is control versus hands-off: robo-advisors run on autopilot, while chat apps like Walnut keep you in the loop and let you approve every trade.

Do chat-based investing apps connect to my real broker?

Some do and some do not. ChatGPT has no account view at all. SoFi centers on accounts you hold inside SoFi. Magnifi and Origin connect accounts to varying degrees. Walnut connects your existing brokerage through SnapTrade (read-only by default) so the chat is grounded in what you actually own, rather than a hypothetical or a separate in-house account.

Is there a free chat-based investing app?

Yes. ChatGPT has a free tier, and Walnut has a free tier as well. Magnifi, Origin, and SoFi offer free access or trials with paid upgrades, and SoFi’s investing accounts have their own terms. Free tiers and limits change often, so check current details on each provider’s site before relying on them.

Is ChatGPT a good chat-based investing app?

ChatGPT is excellent for explaining concepts, walking through scenarios, and drafting a plan in plain language, which is why most people reach for it first. On its own, though, it cannot see your brokerage or live prices, and it can state wrong figures confidently. Treat it as a smart explainer, verify any specific numbers, and use a connected app when you want the chat grounded in your real holdings.

Can a chat-based investing app place trades for me?

It depends on the app. Some are research-and-planning only, while others can route an order. Walnut sits on top of the broker you already own and can prepare trades, but it is read-only by default and requires your approval for every trade, so nothing happens automatically. Always check how an app handles account access and order placement before connecting it.

What should I look for in a chat-based investing app?

Decide whether you want to research, plan, or act on your own holdings. Then check whether it connects to a broker you already own or only its own accounts, whether access is read-only by default, whether it grounds answers in real data or free-associates, and whether it stays descriptive rather than promising guaranteed returns. Walnut fits the act-on-your-own-broker case; match the app to what you actually need.

Are chat-based investing apps safe?

General assistants are safe to ask questions, but they can hallucinate figures, so verify anything specific. For apps that connect to your money, safety depends on how access works: Walnut connects through SnapTrade, a regulated aggregator, reads your holdings read-only by default, and requires your approval for any trade. Check each provider’s security and permissions model before linking an account.

Can a chat-based investing app give advice?

Some are more opinionated than others, but giving regulated investment advice is a legal line that most consumer apps do not cross. They can explain, research, and frame trade-offs without telling you to buy or sell. Walnut is informational and is not an investment adviser; it helps you research and frames holdings against the S&P 500, but the decision and any trade are yours.

Which chat-based investing app knows my real portfolio?

If you want a chat that actually knows your portfolio, you need one that connects your accounts, which not all do. Walnut links the real brokerage you already own through SnapTrade and lets you ask about your actual holdings and themes through Claude or ChatGPT, with each position framed against the S&P 500. ChatGPT can help if you paste in your holdings, but it will not see them automatically.

Is a chat-based app better than a tap-through investing app?

Neither is strictly better; they suit different habits. A tap-through app is fast for routine actions you already know how to do. A chat-based app is better when you want to ask, explore, or reason in plain language without learning the menus. Many people use both: a chat app like Walnut to research and decide, and their broker’s own app to manage the account day to day.

Walnut is informational and is not an investment adviser. App features, pricing, and availability change; verify current details on each provider's site before deciding. Nothing on this page is a recommendation to buy, sell, or hold any security or to use any particular product.
