Summary

Diaform is an AI agent that automates and scales customer interviews, replacing static forms with dynamic conversations.

Editorial Verdict

Diaform is a strong choice for product teams seeking deeper qualitative feedback at scale, offering AI-driven follow-ups and automated analysis. However, its utility is limited by relatively low AI message caps on lower-tier plans and a lack of broader integrations beyond Slack.
