Diaform review
A focused intake tool for teams that want richer responses than static surveys provide.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Diaform turns customer feedback and research intake into AI-led text or voice conversations that can follow up on respondents’ answers. It is aimed at teams working on customer discovery, product feedback, churn surveys, onboarding feedback, or testimonial collection, especially when a static survey is unlikely to draw out enough detail. Projects can include context uploads to inform the AI, while conditional instructions let teams specify when questions should be asked or skipped. Shared links and QR codes provide ways to reach respondents.
Pricing starts with a 14-day trial that includes 250 AI messages. Starter costs $49 per month and includes a custom subdomain, unlimited follow-up questions, advanced analytics, and CSV export. Standard is $89 per month and lists those same features. Pro costs $199 per month and adds Diaform branding removal, targeted respondent links, premium voices, and fast model selection. Business is $499 per month; its listed features include branding removal, a custom domain, organization API keys, and targeted respondent links. Plans are limited by monthly AI messages, projects, and workspace seats, so buyers should compare those limits against expected intake volume.
The workflow combines response summaries and analytics, including sentiment and activity metrics, with automations triggered by conversation events. Slack notifications can alert a team when automation rules fire; webhooks and CSV export support other ways to move response data. Diaform is cloud-based and available through the web and API, with email and documentation listed as support channels. Its logic is conditional ask-or-skip behavior rather than conventional fixed branching trees. Choose it when adaptive text or voice intake and summarized responses matter; teams seeking an ongoing free plan or fixed survey branching should look elsewhere.
