What it does
BlockSurvey is a survey platform for building forms and surveys. It offers end-to-end encrypted responses, AI-assisted question creation, email and SMS campaigns, sharing by link, QR code, or embed, and AI analysis. The site lists a free start, paid monthly and yearly plans, and a demo request. It states that users own and control their data and supports integrations with tools such as Microsoft Excel, Airtable, HubSpot, and Power BI.
The home page says answers are encrypted on the device before they reach BlockSurvey and that the user is the only one who holds the key. It lists no trackers, cookies, or ads and supports fully anonymous responses. A ranking questions page describes drag-and-drop, dropdown, image drag-and-drop, and image selection ranking question types. The about page says BlockSurvey was founded in 2019 and lists ISO 27001, HIPAA, GDPR, FERPA, and SOC 2.
