## The longer explanation

You install a script on your site, once. From then on, Bixlow looks at where you lose sales or leads, proposes what to change and why, builds the change on your real site and launches it as an A/B test or as a personalization for a specific audience. When there is enough data, it tells you which version wins and how sure it is.

You decide which goal matters, who sees what and what goes live. Nothing is published without your approval.


## What it does

- Analyses your site and proposes improvement hypotheses with their reasoning, ranked by impact.
- Builds variants from a plain-language description, without touching your theme or waiting for a deploy.
- Launches A/B and A/B/n tests, and personalizations per audience: campaign or UTM, country, device, new or returning visitor.
- Measures business goals (purchases, forms, clicks) and reports the result with Bayesian statistics, with minimum sample and duration before naming a winner.


## Who it is for

For online stores, SaaS and lead-generation sites that want to improve conversion and have no developer to do it, or whose developer is busy. Also for agencies running several client sites. It works on any site where you can add a script: Shopify, WooCommerce, PrestaShop, WordPress, Webflow or a custom build.


## What it does not do

Bixlow has no feature flags or server-side tests: it works on what the visitor sees in the browser. It does not ship ready-made integrations with other tools; when one is needed, the AI builds it as a Function. And it does not make up results: if there is not enough traffic to decide, it says so.

## Who builds it, and since when

## FAQ
