What is synthetic data and how can it be used for UX research?

Synthetic data consists of computer-generated information that mimics the statistical properties and behavioral patterns of real users. Powered by Large Language Models and orchestration methodologies, it simulates human decision-making and thinking out loud while interacting with digital interfaces.

How is DataDisco different from other synthetic data products?

Existing solutions often lack persistent personas with real-world context. DataDisco combines data-driven persona agents with contextual interface representations to generate feedback that closely mirrors a real audience — not generic chatbot output.

What exactly is a vibe check?

Every persona carries tensions (what blocks them), drivers (what motivates them) and success criteria (how they judge a win). A vibe check scores each session against all three, then compares across versions so you can see which frictions eased and which outcomes passed as your product changed.

Is this a replacement for real user research?

No. Synthetic personas shorten the loop between decisions; they don’t tell you what a real person will do. Use them to arrive at your real research sessions with sharper questions.

How do personas stay grounded in our actual users?

Attach your existing research — interview transcripts, survey exports, analytics summaries — as source documents. Every persona generated under that archetype inherits the grounding. Reach out to us to set up a persona generation demo with your data.

How does the GitHub integration work?

Connect a repo and choose which personas run on which branches. Each pull request gets an automated acceptance test run with step-by-step results and screenshots, reported back on the PR.

Which AI assistants does the MCP server work with?

Claude, ChatGPT, Cursor and any other MCP client. Add the connector once and your workspace’s personas, prototypes and sessions are available where your team already works.

How do you handle our data?

Your data is never shared or used for training. See our privacy policy for full details on how we protect your information.

Which frictions eased

Tensions that showed up in v1 and stopped showing up in v4 — with the sessions that prove it.

Which motivations you met

Drivers the flow actually served, so you can tell a real improvement from a cosmetic one.

Which outcomes passed

Success criteria judged on the persona's terms, not on whether the click path completed.

GitHub integration

A vibe check on every pull request

Connect a GitHub repo and your personas run user acceptance testing on every pull request. Personas exercise real flows and report back with screenshots before the merge.

Each run posts step-by-step results to the PR, so a broken flow is caught by the person who opened it, not by a user after release.
