Drop-in behavioral tracking that AI coding agents can read, query, and fix — in one conversation.
<script
src="https://useractivity.ai/tracker.js"
data-site="YOUR_SITE_ID"
defer
></script>One tag. Zero config. Every behavioral signal, captured.
Prompt "build a signup flow" and you get the flow — not tracking for drop-offs, rage clicks, or abandonment. Observability is never part of the happy path.
PostHog, Mixpanel, Amplitude — they output dashboards and charts for humans. Your AI agent needs structured data and natural language summaries it can reason about.
You can't say "users are dropping off at step 3 — fix it" and have your AI agent act on structured behavioral data. The loop between user behavior and code iteration is open.
Paste a single line into your HTML. Works on any site — React, Vue, Svelte, vanilla HTML, Lovable, Vercel, anywhere.
<script src="https://useractivity.ai/tracker.js" data-site="YOUR_SITE_ID" defer></script>Add this to your project's MCP config. Nothing to install — your agent connects directly to the hosted API.

}Ask your agent about real user behavior. It queries the data, identifies problems, and fixes them — all in one conversation.
You: "Users aren't converting on signup. What's wrong?"
Agent: [calls get_frustration_signals for /signup]
Agent: "The signup page has a frustration score of 34/100.
67% of users never scroll past the first fold, and
11% show u-turn behavior. I recommend moving the
CTA above the fold. Want me to fix that?"Natural language summaries and structured data — designed for AI consumption, not dashboards.
