A library of carefully-designed instruments — for self-knowledge, compatibility, and the questions that don't fit a five-point scale.
Always free. No paywalls. No ads. No "take the test, then sign up to see your results." Reader-supported, independent, made carefully.
Eight specific ways — half about how the questions are written, half about what you actually get out of taking them.
Custom-designed instruments built around moments most existing tests miss. Each test is short, considered, and tells you something you didn't already know.
Wrenlight's independently-designed equivalents to widely-known instruments. Same academic frameworks, our own questions, free to take. Closest to: each card tells you.
Originals beyond the flagships — organized by what they help you understand.
Set aside while the catalog tightens. Each is still playable if you go directly to it — and any may come back to the main catalog with a sharper cut.
Two places the tests lead, once you've taken a few.
A discussion framework woven from both partners' tests — dos & don'ts, accommodations, conversation starters. Insights, never raw results. No compatibility score, ever. See how it will work, and try the interactive preview.
