Testing tools

Leanlab’s Testing Tools are designed to help you test designs, concepts, visuals, interfaces, and messaging in hours (not weeks) and make decisions backed by real customer response. Our testing suite focuses on rapid evaluative feedback.

Preference testing lets you quickly compare options (e.g., designs, visuals, concepts, offers) to see what resonates most. You can then combine the result with qualitative feedback to understand why people chose it.

They answer different questions:

• Preference testing captures stated opinions/perceptions (“Which do you like more, and why?”).
  
  
• A/B testing measures behavior against a KPI in a live (or quasi-live) environment (“Which variant performs better?”).
  
  In practice: use preference testing early (creative direction, messaging, visual direction), and A/B testing later when you can measure real outcomes.
  

A first-click test measures where users click first to complete a task, helping you assess whether a layout or flow is intuitive.

Leanlab frames it as a way to visualize attention/interaction patterns and refine layouts and flows for both digital and physical environments.

Leanlab’s Concept Gallery shares concepts, mockups, and visuals and collects feedback that boosts creative confidence.

You can also collect visuals from customers to understand best practices and physical experiences: useful when you want examples of what “good” looks like in the real world.

We promise speed: run tests and get directional evidence in hours rather than weeks, especially for concepts, visuals, interfaces, and messaging decisions.

Leanlab is powered by an AI agent that can act like a personal research advisor, helping you design your research, going deeper, finding new insights, and turning results into actions (so you’re not stuck with raw feedback).

Leanlab testing tools are particularly suitable for testing concepts, designs, visuals, interfaces, and messaging. Practically:

• Use Preference testing for creative direction and offer/message comparison.
  
  
• Use First-click to validate navigation clarity and whether people start tasks in the “right” place.
  
  
• Use Concept gallery to gather feedback on concepts or mockups/campaign assets and learn from customer-provided visuals.
