What it really isAltIndex — AI-powered alternative data platform for retail stock investors.
Our takeAltIndex aggregates non-traditional signals — app downloads, job postings, web traffic, social media sentiment, and employee satisfaction scores — to surface stock momentum before it shows up in earnings reports.
Paid plans start at $29/mo (Starter), with a free tier available. It pitches a claimed 75–80% AI pick win rate, which warrants independent verification, but the breadth of alternative data sources is genuinely differentiated for retail investors.
Why we rate itDelivers a genuine alternative-data workflow that was previously only accessible to institutional quants, at a consumer price point.
The free tier removes friction for first-time users.
The catchThe 75–80% claimed win rate is marketing-grade and unaudited; performance in choppy markets is unclear.
Pro tier at $99/mo is steep for casual investors, and API access (a key feature) is gated behind the highest tier.

Best / not good for

  • Institutional quants needing raw data feeds and SLA guarantees
  • Crypto-only traders (stock focus dominates the platform)
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: free account signup is instant; AI stock scores and screener are accessible within minutes of onboarding.
  2. Scale breakpoint
    10-stock portfolio cap on Starter forces an upgrade to Pro; API access only unlocks at $99/mo, limiting programmatic use on lower tiers.
  3. Walled garden
    Moderate: data exports and API access exist on Pro, but the AI scoring logic is proprietary and the platform's signals don't port easily to third-party tools.
Still a fit?
If none of these block you, start on the free plan.
