AlphaResearch vs AltIndex

AlphaResearch is an AI document-search engine over SEC filings, earnings transcripts and press releases with sentiment analysis and filing alerts — built for investors who read primary documents. AltIndex scores stocks 1-100 using alternative data (social sentiment, web traffic, app downloads, job postings, insider activity) — built for investors who want signals beyond fundamentals. They answer different questions: 'what did the company say?' vs 'what is the crowd doing?'. No hands-on research-quality comparison was run. Pricing checked 2026-10-24: AlphaResearch Basic $49.99/mo billed quarterly (7-day trial), Enterprise custom; AltIndex Starter $29/mo ($199/yr), Pro $99/mo ($499/yr), limited free tier, 7-day trial on some plans.

Use the same input

Pick one stock with a recent earnings call. Use AlphaResearch to find what management said about margins, and AltIndex to check the social-sentiment score — then decide which answer changed your view more.
