Best AI tools for stock research (2026)

1How we compared

Each tool is described from its own website — pricing page, product pages, help centre or terms — read on 6 November 2026, with the link in the table of sources at the end. Where a feature was not mentioned on those pages, we say so; it does not prove the feature is absent. Prices are the public list prices in the vendor’s currency; promotions are flagged.

The criteria: what the tool is; whether it publishes its own ratings, picks or price targets on named stocks; whether it has a free plan; the starting paid price; whether the interface is available in French; whether it works inside Claude or ChatGPT.

InvestIQ publishes this page and is one of the tools compared. If a fact about any tool is wrong or out of date, write to contact@getinvestiq.com and we will correct it.

2The comparison at a glance

“Not shown” and “not mentioned” mean we did not find it on the vendor’s pages on 6 November 2026.

3The tools, one by one

**AInvest** — An AI research platform “engineered for North American markets”, with real-time US market data, an autonomous research agent (Aime) and, on paid tiers, stock-picking tools. Its about page says Aime “helps frame the trade — suggesting size, stops, and targets”. Monthly plans run from $59.99 to $999.99; yearly prices shown are first-year coupons. More in InvestIQ vs AInvest.

**Danelfin** — An AI stock picker from Barcelona: an AI Score from 1 to 10 estimating the probability of beating the market over three months, with buy/hold/sell signals and trade ideas on higher tiers. Covers more than 15,000 US and European stocks and ETFs; interface in nine languages including French; an MCP server and an API.

**Finary** — A French app that aggregates savings, investments and property across about 20,000 institutions, with a connector for Claude, ChatGPT and other assistants. It is about the whole of your wealth rather than the analysis of a single stock; Finary is also an approved investment firm.

**Fiscal.ai** — Formerly FinChat: a research terminal with financial data on more than 100,000 companies, AI summaries of filings with citations, consensus estimates, broker sync and connectors for Claude and ChatGPT. Interface primarily in English; plans from $49 a month. More in InvestIQ vs Fiscal.ai.

**InvestingPro** — The paid tier of Investing.com: an AI assistant (WarrenAI), Fair Value from 17 models, buy/sell/hold decisions and ProPicks AI portfolios. French site available; prices were not displayed publicly on the day we checked.

**InvestIQ** — An AI equity research platform built in France: stock analysis with a deterministic, published scoring method, cited Deep Research reports, a War Room where opposing analysts debate a thesis, portfolio audits from broker CSV exports, free valuation calculators, and the same research inside Claude, ChatGPT and Cursor. Fullest data on US companies. Free plan; paid plans €19 and €49 a month.

**Koyfin** — A market data and analytics terminal with dashboards, screens and portfolio tracking; no AI research feature found in its product pages. Free plan; paid plans from $49 a month.

**Perplexity Finance** — The finance section of Perplexity: AI summaries citing their sources, earnings, screens and watchlists, using data from providers including Financial Modeling Prep and Fiscal.ai. The pages are viewable without an account.

**Seeking Alpha** — Analysis written by contributors, news, Quant Ratings and AI-generated Virtual Analyst Reports on US-traded stocks. Premium costs $299 a year after an introductory month.

**Stock Rover** — Research, screening and portfolio management for US and Canadian stocks, with scores, fair values and broker integrations on higher tiers. No AI feature mentioned.

**TipRanks** — Aggregated analyst ratings and price targets, insider and fund activity, its Smart Score and AI ratings, with an MCP server for Claude, ChatGPT and Cursor.

**Zacks** — The Zacks Rank, from #1 (Strong Buy) to #5 (Strong Sell), with stock picks from its newsletters. US-focused; no AI feature mentioned.

4Which kind of tool for which need

• **You want a ready-made rating or picks on each stock**: several services publish them (Danelfin, InvestingPro, Seeking Alpha, TipRanks, Zacks, AInvest on paid tiers). Check how the rating is built and what its track record is based on.
• **You want to research and decide yourself, with figures you can check**: research tools that show their data and sources (Fiscal.ai, Koyfin, InvestIQ, Stock Rover).
• **You want answers with sources, quickly**: Perplexity Finance.
• **You want your whole wealth in one place** (savings, life insurance, property): Finary.
• **You want the research inside Claude or ChatGPT**: Danelfin, Finary, Fiscal.ai, InvestIQ and TipRanks have connectors.
• **You want a French interface and a free plan**: Danelfin, Finary and InvestIQ offer both.

Whatever the tool, a rating is not advice tailored to you, and past performance of a rating says little about the future.
