Frequently asked questions
Can I test a prototype before it is fully built?
Yes. Share mockups or screenshots for design feedback, or a working browser prototype for usability testing. Flag unfinished areas so the feedback focuses on the decisions you want to test.
How does market intelligence improve the feedback?
evidenso connects patterns from public reviews, communities and market research with your internal customer knowledge. People’s goals, recurring problems and expectations inform the test, helping you spot missing features as well as usability issues.
Can I use evidenso inside Codex or Claude via MCP?
Yes. Connect evidenso via MCP to request feedback, run usability tests and review results inside Codex or Claude. Improve your prototype in the same conversation where you’re building it.
Are digital-twin responses real customer feedback?
No. Digital twins simulate responses using evidence about your audience. Real participant feedback is a separate layer used to check assumptions. The homepage demos illustrate the workflow.
How is data privacy handled?
Data is encrypted in transit and at rest. Account-level access controls are applied to all research assets. Built for teams in regulated industries with strict data governance requirements.
How do we get started?
Request early access with your email, or book a call. Bring a prototype or feature idea, the audience you want to understand and the decision you need to make. We’ll help you choose a focused first test.
