# Duelpilot vs Tailor

> "Agentic growth" for websites: agents study visitors, ads and competitors, then build A/B tests, personalized pages and hosted landing pages, for performance marketers, growth teams and agencies. Duelpilot is A/B testing run by your own AI agent over MCP, with a person approving every launch. Both can be used by an AI agent over MCP. The biggest difference is who launches: in Tailor an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). Tailor is priced by traffic (visitors or users); Duelpilot is flat per site, without AI credits.

Prices as published by each vendor on the date checked, excluding VAT. Duelpilot has no visitor meters and no AI credits: the AI runs in your own agent's subscription.

## What Tailor does well

- Targeting by campaign, keyword, UTM, traffic source, device and location, tied to ad accounts (tailorhq.ai/integrations/mcp).
- MCP exposes the same tools as Tailor's own in-app agent, including previews and results (tailorhq.ai/integrations/mcp).
- Results measured down to signups, pipeline and revenue; performance-based offer on first landing-page tests (tailorhq.ai).

## What Duelpilot does well

- Your own agent does the research, design, checks and monitoring over MCP (48 tools); no AI bill from Duelpilot.
- A person approves every launch: no MCP tool can approve, launch, pick a winner or ship.
- Always-valid sequential statistics (mSPRT) with Holm correction, sample-ratio-mismatch checks and guardrail metrics.
- Every variant gets a preview link and a site check on phone, tablet and desktop before anyone can approve it.
- Flat price per site, published, from €9/month, and your first test is free on every plan; no visitor meters.

### Where Duelpilot falls short

- You need an AI agent that speaks MCP; without one there is no visual editor to build variants by hand.
- No heatmaps or session recordings: Duelpilot counts results and sends variants to your own analytics.
- A young product (2026): fewer integrations and a shorter track record than established tools.

## Which one should you choose?

### Choose Tailor if…

Choose Tailor if your traffic is mostly paid and you want landing pages personalized per campaign, keyword or account, with results tied to pipeline and revenue.

## FAQ

### Can Tailor's MCP launch tests?

It can, if you allow it: Tailor says launch can be open to agents or reserved for humans. Duelpilot has no launch tool at all; launches come from a person or an owner's autopilot policy within guardrails.

### Is Tailor's MCP on every plan?

MCP and API are listed from the Pro plan, which is custom-priced (checked 17 Oct 2026). Duelpilot's MCP is on every plan, including Starter (€9/month).

### What drives Tailor's price?

Tailored page visitors and identified-visitor credits, from $250/month on Basic. Duelpilot is flat per site with no visitor meter (fair use applies).

### Does Duelpilot personalize pages per ad campaign?

Duelpilot targets tests by URL, device, source/UTM, referrer and more, but it is an A/B testing tool, not a per-account personalization engine. For ad-to-page personalization Tailor is the more specialised tool.
