AltIndex

AltIndex collects company data from around the internet, including Reddit mentions, web traffic, app downloads, job postings and employee sentiment. It uses that data to score stocks and flag changes. You can upload a screenshot from any brokerage and it reads your positions, gives each holding an AI score from 0 to 100, and rolls those into one portfolio score. Nothing needs to be linked, and holdings that score below 60 are pointed out.

Other features include real-time alerts for spikes in popularity, insider activity or sentiment, and AI stock picks trained on alternative data. AltIndex says the picks have a 61% win rate. There's also an AI chat agent you can ask about your holdings in plain English, plus Autopilot portfolios you can copy automatically. The site also has pages on Reddit stocks, congress trading, the earnings calendar and the fear and greed index.

AltIndex runs on the web, iOS and Android, and watchlists sync between devices. Developers and funds can use an API, an MCP server for AI tools, and institutional data feeds. Signup is free with no credit card required, and paid plans are listed on a separate pricing page.
