## Who This Is For

### Individual Investors
Wall Street research desks run on analyst teams — one analyst per sector, a memo for
every company in the book. Individual investors have always been on their own. Margin of
Insight changes the economics: hire an AI analyst for any covered stock, on demand, from
$0 (primer) to $2 (full 19-step investment memo). No annual commitment. Credits never expire.

**Coming soon:** The Analyst Agent — a persistent AI analyst assigned to your coverage
universe. Monitors earnings, flags catalysts, files updated research notes automatically.
Stop hiring per report. Build a standing team.

### AI Agents & LLMs
Pre-computed equity research as structured JSON. Free tier requires no authentication.
A full 19-step investment memo that costs ~$7–9 for an LLM to self-produce is available
for $2 with P50 latency under 200ms. Autonomous x402 micropayment support coming soon.
