Research Workspace

Not just studies. A full research project workspace.

Most tools give you a study runner and nothing else. CardSort gives you a project workspace — track competitors, capture interviews, run studies, synthesize findings, and publish stakeholder reports.

Competitive Analysis

Track competitors with AI-generated SWOT observations. Identify market gaps before running your first study.

Discovery Interviews

Log interview notes, track participant sentiment, and surface recurring themes automatically with AI.

Validation Studies

Card sorts, tree tests, and surveys — validated with real users via Prolific or your own audience in minutes.

Findings & Themes

Pin insights, pain points, opportunities, and risks across every phase. Group by theme, filter by type.

Pro

Stakeholder Reports

Publish a shareable, AI-narrated research report with one click. No login required for viewers.

Pro

AI Throughout

SWOT suggestions, interview theme detection, synthesis reports, and AI-powered insights.

Why Teams Switch

Maze is powerful. It's also overkill.

Most teams don't need a $200/month enterprise platform. They need to run research, get results, and ship. That's CardSort.

5-minute setup

Pick a study type, add your cards, publish. No 30-minute onboarding flows, no seat-based pricing negotiations.

$0/month

Unlimited studies, real-time analytics, dendrograms, similarity matrices, CSV export. The features Maze charges $99/month for.

Refreshingly simple

No seat limits, no feature gates, no sales calls. Sign up, create a study, share a link. Your participants don't need accounts either.

Comparison

More features. Less money. No compromises.

Built-in Recruitment

Maze doesn't recruit participants. We do.

  • Prolific integration — verified participants from ~$1.50
  • 10 free recruitment credits on every account
  • AI test responses to preview before you launch
  • Share your link anywhere — email, Slack, social
