Best Free AI Research Tools for Investors

TipRanks

TipRanks combines analyst ratings, targets, expert rankings, Smart Score, AI analysis, news sentiment, insider signals, hedge-fund activity, and portfolios. It is useful for comparing market views quickly, with Premium and Ultimate adding deeper expert, portfolio, export, and AI tools.

Unusual Whales

Unusual Whales tracks options flow, dark pools, congressional trades, insider activity, market data, alerts, screeners, and social sentiment. It is built for active traders and alternative-data research, not a broker, portfolio ledger, or guarantee that unusual activity predicts returns.

13F Insight

13F Insight pulls institutional holdings, insider trades, and ownership filings into one research workspace. Its AI can answer questions with filing citations, but the filings arrive late and the generated summaries still need a check against the SEC documents.

Alpha Spread

Alpha Spread combines DCF and relative-value estimates, stock reports, screens, alerts, analyst forecasts, watchlists, and a company-question assistant. Free use is metered weekly.

AlphaResearch

AlphaResearch puts filings, transcripts, press releases, estimates, news, insider trades, ownership, and fund holdings in one searchable workspace. It is aimed at document-heavy research. Global coverage and spreadsheet add-ins require Enterprise, and the premium trial asks for a card.

Berkshire Hathaway Archive (Memorex)

Berkshire Hathaway Archive by Memorex is a free searchable collection of Warren Buffett shareholder letters and Berkshire annual-meeting transcripts. Search it for the company's thinking on capital allocation, incentives, moats, management, insurance, and long-term investing. It covers one company, not the wider market.

Fintel

Fintel brings short interest, off-exchange volume, institutional ownership, insider trades, ETF exposure, options sentiment, filings, screens, alerts, APIs, and AI research into ticker pages.

TickerTrends

TickerTrends estimates public-company KPIs from search, web traffic, apps, social, reviews, news, transcripts, financial data, and consensus. It can add alternative evidence for investors and quants, but the signals are proxies and need validation.
