About AltIndex
AltIndex is an alternative-data research platform that scores every liquid US stock from signals that show up in the real world before they show up in a quarterly report: Reddit and social buzz, web traffic, app downloads, job postings and employee sentiment, insider transactions, and congressional trades. Each company gets a 0–100 AI Score that is refreshed daily, and that score feeds AI stock picks, real-time alerts, a screener, and a portfolio view that grades every holding you own.
The pitch on AltIndex’s homepage is “Catch trends early with alternative data” — your portfolio’s AI analyst that never sleeps. It positions itself as hedge-fund-grade alt-data for retail investors, and it publishes the receipts: every AI Stock Pick is timestamped and tracked on a public results page, and the Autopilot portfolios have a written rulebook and the company’s own money in them.
AltIndex is operated by AltIndex LLC, a subsidiary of Invested Inc. It is a data and analytics platform, not a broker and not a registered investment adviser; its disclaimer is explicit that nothing on the site is a recommendation to buy or sell any security.
Key features
From AltIndex’s live homepage, product pages, and pricing page:
- AltIndex AI Score (0–100): one number per company blended from four scored pillars — Audience (follower growth across social platforms), Hiring (job postings and employee outlook on LinkedIn and Glassdoor), Customer traction (web traffic, app downloads, forum sentiment), and Fundamentals (analyst targets, insider buying, revenue growth, earnings quality). Refreshed daily across nearly 3,000 US stocks.
- AI Stock Picks: when a stock crosses the model’s confidence threshold, AltIndex publishes a buy or sell signal with a target price, the supporting alt-data signals, a confidence level, and a 3–9 month outlook. Starter shows the top 25 picks; Pro unlocks all 200, updated daily. The public results page tracks every pick from entry price to today — the rolling 12-month window showed 158 picks, a 57% win rate, and a +17.6% average return when we checked.
- Real-time stock alerts: alerts fire when a signal breaks out of its normal range — Reddit mention spikes, app download surges, web traffic jumps, hiring waves, AI Score crossings, sentiment shifts across Reddit, StockTwits, and TipRanks, Truth Social posts about a public company, and Instagram or TikTok follower spikes. Delivered to your dashboard, email, and the iOS/Android app.
- Portfolio AI Score: connect a brokerage or just upload a screenshot of your positions — AltIndex reads every holding, scores each one, blends them into a single portfolio score, and flags the names scoring below 60 that drag you down. A public leaderboard ranks member portfolios.
- Ask AltIndex AI: an AI analyst that knows your holdings. Ask “What is the bear case for NKE?” or “Which of my holdings has the worst insider signals?” and it answers from live AltIndex scores, fundamentals, and alternative data rather than made-up numbers.
- Stock screener: filter the universe by AI Score, social mentions, insider buying, hiring trends, and more. Starter is limited to 3 filters; Pro gets the full screener with export.
- Autopilot portfolios: three rules-based portfolios built on AltIndex data — AltIndex AI Top 10, Reddit’s Favorites, and Robotics Infra — each with a published thesis, eligibility rules, weekly review cadence, and hard stops. Copy any of them on Autopilot (by Invested) and the trades route into your brokerage.
- MCP server for AI tools: add mcp.altindex.com as a connector in Claude, Cursor, ChatGPT, or any MCP client and ask about any stock, your portfolio, or your watchlist in plain English. Included with Starter and Pro; read-only, never places trades.
- Free data pages: trending Reddit stocks, congress trading, Fear & Greed index, earnings calendar, meme stocks, short squeeze candidates, and stock comparisons are browsable without an account.
How it works
- Open AltIndex from our partner link and search any ticker — no account is required to see its AI Score and headline signals.
- Create a free account, then pick Starter or Pro to begin a 7-day free trial (card required; cancel before it ends and you are not charged).
- Connect your brokerage or upload a portfolio screenshot, set alerts on the names you own, and install the mobile app so breakouts reach your phone.
Everything runs in the browser and the iOS/Android apps, with watchlists and portfolios synced across devices. Payments are processed by Stripe and you can cancel anytime from account settings before the next billing cycle.

Who AltIndex is for
AltIndex is built for investors who want to see demand, attention, and insider behaviour before it lands in earnings:
- Swing and position traders who want catalyst-driven alerts — Reddit spikes, insider buying, hiring waves — within minutes of the signal breaking out
- Long-term investors who want hiring, app download, and web traffic trends sitting next to fundamentals as an early read on the business
- Anyone with a brokerage account who wants every holding scored and the weak links flagged without building a spreadsheet
- Developers and AI-tool power users who want alt-data inside Claude, Cursor, or ChatGPT via MCP, or a REST API for their own models
It is not a charting package, Level 2 tape, options-flow terminal, or broker. AI Scores and picks are research signals with a published track record, not guarantees, and AltIndex says so on every page.
AltIndex vs other research tools on SaveOnTrading
SaveOnTrading also covers AI and data-driven stock research platforms such as Danelfin, Tickeron, Stock Analysis, Koyfin, and Fiscal.ai. AltIndex’s differentiation is the alternative-data layer — social buzz, web traffic, app downloads, hiring, insider and congressional trades — scored daily and pushed as real-time alerts, plus an MCP server that puts that data inside your AI assistant.
Trade-offs to weigh: Starter caps you at 25 watchlist stocks, 3 screener filters, and the top 25 picks, so heavy screener users will want Pro at $99/month. Coverage is US-listed stocks only. If your edge is deep fundamentals and valuation models, Koyfin or Fiscal.ai go further; if you want to know what the crowd, the hiring managers, and the insiders are doing before the print, AltIndex is the specialist.
Limitations
- Not investment advice. AI Scores, picks, and alerts are data-driven estimates; alternative-data signals may be delayed or incomplete, and past pick performance does not guarantee future results.
- US stocks only — nearly 3,000 liquid US-listed names. No international equities, and ETFs, SPACs, and thinly traded names are excluded from the Autopilot portfolios.
- Starter limits watchlist size, brokerage connections, screener filters, and the number of picks; the full screener, all 200 picks, and the developer API key are Pro-only.
- AltIndex’s terms state a no-refund policy — payments are final, including partial periods. Cancel before your 7-day trial ends to avoid the first charge, and cancel before renewal to stop future billing.
- The SAVEONTRADING code only works at the web checkout for new customers, not on in-app App Store or Google Play subscriptions.
