Overview
CustomFit.ai is a conversion optimization platform built from the ground up for D2C and e-commerce brands.
It combines website personalization, A/B and multivariate testing, product recommendations, and 100+ conversion widgets under one roof, with a no-code visual editor that lets marketers ship experiments without engineering tickets.
The AI layer is not an upsell: every plan includes AI Copilot, which builds page changes from plain-English descriptions, AI Wingman, which auto-optimizes toward winning variants, and the AI Conversion Optimizer, which proposes test ideas. Its pricing model is the most distinctive thing about it: plans scale by monthly visitors rather than seats, and every tier includes unlimited users and unlimited experiments.
Core starts at $79/month for up to 10,000 monthly visitors, with custom pricing for higher traffic.
Customer-published results include a +32% conversion lift from personalized recommendations and a +24% average order value lift from product recommendations.
For Shopify brands that want to run serious CRO programs without a dedicated optimization team, it is one of the most complete platforms we have reviewed, though its e-commerce focus makes it a poor fit for B2B lead-gen sites.

CustomFit.ai stands out for bundling serious A/B testing with AI-powered personalization at a visitor-based price. For D2C teams already on Shopify it is one of the most complete CRO stacks we have reviewed.

The AI Copilot genuinely lowers the barrier to experimentation, but the platform's e-commerce focus means B2B marketers should look elsewhere.
