Best AI Stock Research Tools in 2026

AlphaSense

A market-intelligence search engine over filings, earnings-call transcripts, broker research, Tegus expert-call transcripts and news, with a generative AI layer (Assistant) that summarizes and answers questions across that corpus.

• What the AI does: Searches and synthesizes a corpus it puts at more than 500 million premium documents, then generates cited summaries and answers across filings, transcripts and research.
• Data coverage: Filings, earnings transcripts, broker and analyst research, Tegus expert-call transcripts, news, and private and public company data.
• Price: Enterprise subscription; no public per-seat price (a free start option exists, but the full corpus is sold to institutions).
• Best for: The deepest document research: filings, transcripts, broker notes and expert calls, with cited sources.
• One honest limitation: Built and priced for professionals and institutions, so it is overkill (and out of budget) for most individual investors.

Danelfin

An AI stock-scoring platform that assigns each stock an AI Score from 1 to 10 estimating the probability of beating the market over the coming months, built from thousands of technical, fundamental and sentiment features computed per stock every day.

• What the AI does: Scores individual stocks with an AI Score (1 to 10) and shows the feature buckets behind it.
• Data coverage: Technical, fundamental and sentiment features across US and European stocks and ETFs, distilled into a single score.
• Price: Free plan plus paid subscription tiers (flat, no fee on assets).
• Best for: The deepest quantitative read: a probability-style score per stock.
• One honest limitation: It outputs a score, not the research narrative, so it answers whether more than why, and it does not read your own holdings.

Walnut

An AI investing app that researches a stock against your own position in it. It connects the brokerage you already use, read-only by default, and shows how large the stock is in your portfolio, how it has done against the S&P 500 over the past year, and whether it reads as keep, trim or exit. You can ask about it, or a stock you are considering, in Walnut's own assistant with web search, or inside Claude and ChatGPT through its connector, then turn a thesis into a basket with target weights.

• What the AI does: Gives each holding a keep, trim or exit read from its one-year price return against the S&P 500, momentum and position size, flags any holding above a quarter of the portfolio, answers follow-up questions with web search, and drafts the trades that would bring a basket back to target, placing only the ones you approve.
• Data coverage: Your live broker holdings (read-only by default), per-stock price history against the S&P 500, web search, and a catalog of thematic stocks and ETFs.
• Price: Free, including the AI assistant up to a per-session allowance; Walnut Unlimited is $9.99 a month on the web; no fee on assets.
• Best for: The deepest read on a stock you already own, framed by its size in your portfolio and its return against the S&P 500.
• One honest limitation: It has no filings search, transcripts or estimates database, and broker feeds carry no cost basis, so it shows one-year price returns rather than profit and loss.

FinChat (Fiscal.ai)

A conversational research platform (rebranded Fiscal.ai) that answers natural-language questions about one company's fundamentals, segments and KPIs, and builds charts and models from a structured financial dataset.

• What the AI does: Answers plain-English questions about a stock's fundamentals and KPIs, pulls the underlying numbers, and generates charts and comparisons (a finance-tuned chat over a structured dataset).
• Data coverage: Standardized fundamentals, segment and KPI data, estimates, and earnings-call transcripts across global equities.
• Price: Free tier plus paid subscription tiers (flat, not a percentage of assets).
• Best for: Fundamentals in plain English: segments, KPIs and margins on one company, with charts back.
• One honest limitation: Centered on fundamentals and modeling rather than reading your accounts or expert-network calls.

Koyfin

A web research terminal for individual investors, with per-company fundamentals, estimates, charting, screeners and dashboards, positioned as an affordable alternative to a full professional terminal.

• What the AI does: Newer AI features summarize and answer questions over its data; the core product is data, charts and screeners rather than a generative assistant.
• Data coverage: Fundamentals, estimates, price and macro charts, screeners and watchlists across global equities and ETFs.
• Price: Free; Plus $39/mo; Premium $79/mo (up to 30% off with an annual plan).
• Best for: Terminal-style fundamentals and charting on one stock at an individual-investor price.
• One honest limitation: Primarily a data-and-charting tool, so the AI layer is lighter than a purpose-built research assistant.

TIKR

A fundamentals and valuation platform for individual investors built on institutional-grade data, with per-company financials, consensus estimates, ownership and valuation models across global equities.

• What the AI does: Newer AI summaries condense earnings and filings; the core is standardized financials, estimates and valuation tooling for one company at a time.
• Data coverage: Standardized financials, consensus estimates, valuation multiples, ownership and transcripts across global equities.
• Price: Free; Plus $24.95/mo; Pro $54.95/mo; Ultimate $119.95/mo.
• Best for: Institutional-depth fundamentals and estimates on a single stock at a retail price.
• One honest limitation: A data-and-valuation workbench, not a source-cited chat assistant or a connected-account tool.

Seeking Alpha

A research and analysis platform combining contributor articles, quant ratings and fundamentals, with AI features that summarize articles, earnings calls and the bull-and-bear case on a stock.

• What the AI does: Summarizes articles, earnings calls and the bull-versus-bear arguments, and pairs them with its quant Factor Grades and rating (AI on top of human and quant research).
• Data coverage: Contributor analysis, quant ratings and factor grades, fundamentals, estimates and earnings transcripts.
• Price: Free tier plus paid Premium and Pro subscriptions (flat).
• Best for: The bull and bear case on a stock alongside quant ratings, now with AI summaries.
• One honest limitation: Article quality varies because much of it is contributor-written, and the AI mostly summarizes that content rather than reasoning over your holdings.

Bloomberg Terminal (AI features)

The professional market-data and news system, now with AI features layered on: AI-generated earnings-call summaries, document search, and a natural-language query layer over its data and news.

• What the AI does: Summarizes earnings calls and documents, answers natural-language queries over Bloomberg data and news, and surfaces relevant filings (AI on top of the core terminal).
• Data coverage: Real-time and historical market data, news, filings, transcripts, estimates, and fixed-income and macro data at institutional depth.
• Price: Institutional subscription (well into thousands of dollars per user per year).
• Best for: Professionals who already live in the terminal and want AI summaries over its data and news.
• One honest limitation: Cost and complexity put it out of reach for almost all individual investors; it is built for the desk, not the retail brokerage account.

Perplexity Finance

The finance mode of Perplexity's AI answer engine, which answers questions about stocks, earnings and markets with cited web sources and shows price history and basic fundamentals inline.

• What the AI does: Answers market and company questions in natural language with linked citations, and pulls in quotes, fundamentals and recent news from the web.
• Data coverage: Web-sourced news and analysis, near-real-time quotes, basic fundamentals and earnings information, with citations.
• Price: Free tier plus a paid Pro subscription (flat).
• Best for: Fast, cited answers to market and company questions without leaving a chat box.
• One honest limitation: A general answer engine pointed at finance, so coverage is broad but shallow on deep fundamentals, and it does not see your portfolio.

Sentieo (now part of AlphaSense)

A financial-document research and workflow platform (search across filings and transcripts, plus note-taking and a research management layer) that AlphaSense acquired and folded into its platform.

• What the AI does: Searches and summarizes filings and transcripts and links findings into a research notebook; its capabilities now live inside AlphaSense's document engine.
• Data coverage: Filings, earnings-call transcripts and news, with a document-annotation and research-management layer.
• Price: Enterprise subscription (now consolidated under AlphaSense).
• Best for: Document search plus a research-notebook workflow on a single name (now delivered through AlphaSense).
• One honest limitation: It no longer exists as a fully standalone product; new users are pointed to AlphaSense, so evaluate it there.

Magnifi

A conversational AI investing tool you can ask natural-language questions about funds, stocks and holdings, with screening and discovery features and some account connection.

• What the AI does: Answers plain-English research questions and helps screen and discover funds and securities.
• Data coverage: Funds, ETFs and stocks with screening data and fundamentals, oriented toward discovery.
• Price: Free plan; Premium is a paid subscription.
• Best for: Plain-English research and fund discovery in a chat interface.
• One honest limitation: Skews toward fund discovery rather than deep, source-cited research on a single company.

Best for deep document research (filings, transcripts, analyst notes)

If your thesis depends on reading the primary sources (10-Ks, earnings calls, broker research) and getting cited summaries, AlphaSense is the pick.

1. AlphaSense. Searches and synthesizes 500M+ premium documents, including filings, transcripts, broker research and Tegus expert calls, with a generative Assistant that cites its sources.

Best for the deepest read on a stock you already own

If the stock is already in your account, the question is what it is doing to your portfolio, and Walnut is the pick.

1. Walnut. Reads the stock against your own position: its size in your portfolio, its one-year return against the S&P 500, momentum, and a keep, trim or exit read, with any holding above a quarter of the portfolio flagged. Read-only by default; it places only the trades you approve.
2. Magnifi. Conversational with some account connection, stronger on fund discovery than on single-stock depth.
