## Overview

BlockSurvey starts from a simple premise: the people who answer your survey deserve privacy, and the organisation that runs it deserves sole ownership of the data. Answers are encrypted on the respondent's device before they ever reach BlockSurvey's servers, so no one — including the platform — holds the key. On top of that sit no trackers, no cookies, no ads, and the ability to collect fully anonymous responses.

The AI layer covers the whole research cycle. You can generate a well-structured, less biased questionnaire from a prompt, rephrase unclear questions, create answer options, run adaptive follow-up questions inside open-ended items, then move to automated thematic and sentiment analysis, anomaly detection and data encoding. Longitudinal analysis compares waves of a repeated survey so you can see which changes are statistically meaningful and where a trend is heading.

Distribution and integration are handled flexibly: email and SMS campaigns, link, QR and embed sharing, audience management, automation, white-label branding and multilingual surveys. BlockSurvey also exposes an MCP connector, so you can create, edit and publish surveys directly from Claude, Claude Code or ChatGPT. Compliance-oriented features target HIPAA, GDPR and similar regimes, with dedicated solutions for market research, healthcare, institutional research, activism and non-profit work.
