AltIndex

What AltIndex helps you research

AltIndex is a stock-research platform that combines company information with alternative data. Its signals include social discussion, website traffic, app downloads, hiring activity and insider activity. It gives investors another set of observations to examine alongside financial statements and company announcements.

Users can search companies, build watchlists and inspect AI-generated scores. The platform also offers portfolio analysis and natural-language questions about holdings. It is relevant to individual researchers and to developers who want alternative-data inputs for a research application. Its indicators are starting points for investigation, rather than a complete explanation of a company's value.

Scores, portfolios and stock alerts

AltIndex assigns stock scores and combines holding-level scores into a portfolio view. The homepage describes importing positions from a brokerage screenshot. Check imported tickers and amounts before relying on the resulting analysis, especially where a screenshot contains abbreviated names or several similar instruments.

The stock-alert workflow highlights changes in tracked signals, such as increased discussion or hiring activity. Alerts can help a reviewer decide which company deserves another look. A surge in mentions describes attention; understanding whether that attention reflects business improvement, controversy or speculation requires additional context.

REST data and a read-only MCP connector

The developer documentation covers REST access to alternative-data fields and historical series. Accounts have limits on requests, history windows and tickers per call. Field definitions and collection information matter when comparing two companies or calculating changes over time.

The MCP connector exposes research data to compatible AI assistants. Account sign-in enables portfolio and watchlist queries, while an API-key route supports data access. AltIndex describes this connector as read-only: it retrieves information and does not place trades or change the account. Confirm access for the specific client and subscription before designing a workflow around it.

An example research workflow

A researcher tracking a small group of software companies could create a watchlist and review alerts about app activity, hiring and investor discussion. When a signal changes, open the company view and compare the dates and context with an earnings release or other primary company material. Record both the observation and the explanation being considered.

If using the API, retain the response date and field definitions with the analysis. Avoid treating a missing metric as a zero. If using an AI assistant, inspect the numbers and their sources in the response before including them in a research note. This suggested process helps separate a measured signal from an interpretation of that signal.

Limitations and account access

Alternative datasets cover particular entities and collection methods; they do not provide a complete picture of every business. Changes in online activity can have several causes, and an AI score does not assure a future stock return. AltIndex's disclaimer describes its information as general and does not warrant its accuracy or completeness.

Some public research and a free-account route are offered, while the pricing page separates paid platform access from API plans. Check watchlist capacity, history, request budgets, MCP access and permitted data use for the intended account. Redistribution and higher-volume institutional delivery require their own terms.
