The three study types
In-depth Interview
No stimulus required — just a conversation. Use this when you want to learn from people’s lived experience. Charles guides a focused discussion about what they did, why, and what they’d change. Reach for it when you’re doing discovery, digging into a decision moment, exploring before you commit to a direction, or hunting for unmet needs.Concept Test
You have something to show. An ad, a landing-page mockup, packaging, a feature explainer. Add the image or video, and Charles walks participants through reacting to it. Reach for it for creative testing, messaging validation, packaging or pricing-page reactions, or A/B-style concept comparison.Prototype Test
You have something to try. A prototype, a clickable mockup, or a live site. Share the link and participants work through it while narrating their thinking. Reach for it to validate a flow before you build it, find where people get stuck, compare an old design against a new one, or run a pre-launch usability check.Study types in depth

What if my research spans more than one study type?

Can I show an image in an in-depth interview?
Can I show an image in an in-depth interview?
Yes. In-depth interviews accept concept images too, so a conversation can turn into a concept test partway through if that’s what the moment calls for.
