What teams are saying

Lupine is the fastest I've ever gone from URL to structured experiment ideas. What impressed me most wasn't just the speed, it was the reasoning behind each recommendation — grounded in real experimentation data, not UX best practices pulled from a blog post.

Zharina Pelea

Lupine feels like a very promising platform, especially in how it visualizes experimentation and testing opportunities. I could see it being very useful for testing user experiences and quickly communicating insights to stakeholders.

Ric Pettit

It feels very focused on actionable UX insight rather than just surface-level analytics. It's much easier to quickly identify opportunities and prioritise improvements without spending hours interpreting data.

Richard McAuley

This CRO platform feels like it's heading in a really strong direction. It doesn't just highlight issues, it points you towards specific test ideas, taking a lot of the guesswork out of what to try next.

Vicki

While having a website that attracts clients is essential, the ability to effectively convert visitors is even more critical, and Lupine addresses this need directly. This is a solution we clearly see ourselves integrating into our workflow on a regular basis.

FAQs

Questions, answered

What is Lupine?

Lupine is an evidence-based, AI-powered Conversion Rate Optimization (CRO) tool that analyzes webpages and surfaces expert, test-ready ideas with full resolution variant wireframes to improve website conversion. It's built on over 15 years of dedicated CRO agency experience and more than 10,000 validated tests, using GAIN Conversion's proprietary frameworks like the Lever Framework, Confidence AI, and PIE Prioritization Framework.

Who is Lupine for?

Lupine is built for teams whose website is a critical channel and who want evidence-based recommendations to test their site and increase the likelihood of turning traffic into purchases, sign-ups, or leads. It's ideal if your team values high-quality insights with a top CRO agency's level of rigor.

How is Lupine different from standard A/B testing tools?

Traditional A/B tools let you run experiments but don't tell you what to test and why. Lupine focuses on the analysis, ideation, and visualization layers, using real-world test history from GAIN Conversion and the proprietary Lever Framework, to generate evidence-based, ready-to-run experiment ideas you can deploy through your existing testing stack.

How does Lupine actually work?

Lupine uses several proprietary tools and industry-leading frameworks from GAIN Conversion, such as the Lever Framework, Confidence AI, and PIE Prioritization Framework, to identify test-ready ideas from over 15 years of data across more than 10,000 tests.

What kind of results can I expect?

Teams typically see deep analysis of a webpage in minutes, a clear prioritized list of problems and hypotheses, experiment ideas backed by evidence and reasoning, exportable visualizations, and faster test velocity with a higher likelihood of conversion uplift.

How do I start using Lupine?

Sign up with your work email or SSO, then paste a website URL — no credit card needed. Lupine takes about 15 minutes to run your first analysis, and you can review the reasoning, evidence, and recommendations before deciding whether to go further.

How much does Lupine cost?

Your first analysis is completely free, no credit card required. If you'd like to keep going after that, see our pricing page for trial and plan details.

Does Lupine do anything with the data from URLs it analyzes?

Lupine's input is simply a website URL, with no snippets, plugins, or direct integrations, and it doesn't collect personally identifiable information from end users. Any data used to improve the Confidence AI model is anonymized and generalized, never traceable to a specific company or client.

What is the cancellation and refund policy?

Your first analysis is free and doesn't require a card, so there's nothing to cancel. If you move on to a paid plan afterward, full cancellation and refund terms are on our pricing page.
