# AXO

> AXO is the agentic experience layer: website personalization that scores each visitor's in-session behavior and reshapes the page to match — live, in about 200ms, with no CDP, identity graph, or data warehouse required. Every operation is exposed as one of 130+ MCP tools, so AI agents (Claude, ChatGPT, custom harnesses) can operate the system end to end. Lift is proven with an always-on holdout, not claimed from a dashboard.

Key facts:
- Installs with one script tag; typical time to a first live variant is under an hour.
- Works on 100% of traffic, including anonymous visitors — behavioral scoring needs no login, CRM record, or third-party cookie.
- The live decision path is deterministic: no LLM call per pageview, no inference cost, reproducible decisions. Generative AI works upstream, drafting variants a human reviews.
- Agent surface: 130+ MCP tools plus REST parity, hosted MCP endpoint (no local install), scoped role-gated tokens.
- Measurement: always-on randomized holdout; lift is reported against the control group.
- Pricing is public: Starter $500/mo, Growth $2,000/mo, Scale from $5,000/mo, all with a 14-day free trial ([pricing](https://axoapp.ai/pricing)).
