What a mobile AI research assistant needs to provide

A mobile AI research assistant for on-the-go investors needs to provide analytical capability from a phone without requiring a desktop. It also needs a conversational interface for specific questions about individual instruments, with responses grounded in live or real-time market data rather than static training data.

The relevant test is whether the primary research capability is available from the mobile interface, not simply whether a service has a phone app. For this comparison, the criteria include native iOS and Android access, conversational research, data-grounded responses, coverage beyond US equities, and no desktop login requirement for the primary analytical output.

Opes Borsa: cross-asset conversational research on mobile

Opes Borsa is mobile-native, with iOS and Android apps serving as the primary interface rather than a companion to a web platform. Luna, its conversational analyst, answers questions about covered instruments across equities, commodities, forex, and cryptocurrencies.

Responses draw on the Trend Signal, Signal Confidence Score, Sentiment Layer's live news classification, and AI Research narrative. This means a conversational query is connected to the platform's current analytical outputs rather than only returning generic information.

Coverage and mobile tools

• Equities across the US, UK, Germany, France, and Canada

• Commodities, forex, and crypto

• Cross-asset watchlist

• Explore

• Macro Calendar

• Full signal layer available from the phone without desktop access

Barebone AI: detailed per-stock research for US equities

Barebone AI is mobile-first on iOS and Android and provides conversational research focused on individual equities. Its output adapts to the user's stated proficiency level and can cover fundamentals, fair value analysis, technical levels, insider data, and sentiment in one conversational response.

Barebone AI's coverage is strongest for US equities. Its documentation notes that data depth becomes thinner on smaller international exchanges. It is research-only, providing analysis and levels without a live signal system with disclosed confidence scores and realised return history.

Reviews across app stores rate Barebone AI 4.8 out of 5 on iOS.

Magnifi: conversational discovery and portfolio integration

Magnifi has iOS and Android apps with a conversational natural-language interface for discovering and comparing US securities, ETFs, and mutual funds.

Its conversational layer is primarily a search and discovery interface. Users can ask for investment ideas matching particular criteria and receive relevant options. Magnifi also provides portfolio analysis across linked brokerage accounts.

Magnifi's conversational output is search-driven rather than based on a proprietary signal architecture.

Koyfin: mobile monitoring connected to a web terminal

Koyfin has iOS and Android apps that sync watchlists, portfolio data, and alerts from its web interface.

Independent reviews describe the mobile app as functional for monitoring, while noting that advanced analytical features are better suited to the web platform. Koyfin is a data terminal with a mobile companion rather than a conversational AI research interface.

Where Opes Borsa fits and who should look elsewhere

Opes Borsa fits investors who want cross-asset conversational research and a live signal layer accessible from a mobile device. Luna operates inside the platform's wider analytical system, so a question about an instrument can draw on its current Trend Signal state, Signal Confidence Score, Sentiment Layer classification of recent news, and AI Research synthesis of earnings transcripts and analyst consensus.

The cross-asset scope allows an investor to ask about a commodity position, currency pair, and European stock in the same session without switching apps.
