• Turns scattered research into a searchable organisational asset.
• Automatic transcription and AI-assisted theme detection save real analysis hours.
• Good at making findings visible to people who did not attend the sessions.

• The reference tool for card sorting and tree testing; the analysis visualisations are excellent.
• Tree testing validates navigation before any build effort is spent.
• Well-established methodology support and training material.

• It stores and analyses research; it does not recruit or run sessions.
• Value depends entirely on discipline — an untagged repository is a folder.
• Costs scale with the number of contributors.

• Narrow scope — it does not do usability testing of interfaces.
• Expensive per seat for occasional use.
• Interface is dated in places.
