BlockSurvey is a privacy-first survey tool that encrypts every response end to end so only you can read it. It pairs that secure base with AI question writing and automated analysis.
About BlockSurvey
What Is BlockSurvey
BlockSurvey is a privacy survey tool for teams that cannot hand their data to a third party. Answers get encrypted on the respondent's device before they reach the company, so only you can read them.
Founded in 2019, the platform now serves more than 1,000 organizations across 50-plus countries and handles over 10 million responses a year. It targets teams that work with sensitive information, like clinics handling patient intake, universities running research, and HR groups gathering feedback.
The main trade-off is that its pricing sits well above free form builders. You pay for the encryption, the compliance paperwork, and the AI tooling, not just for a blank survey canvas. Teams that only need a quick poll might not get their money's worth, while groups handling confidential data often will.
Getting Started
- Sign up for an account on the BlockSurvey website and start the 14-day free trial.
- Describe what you want to ask, and let the AI draft the questions, or pick a template and build the survey yourself.
- Add logic, branding, and delivery channels like email, text, QR code, or a website embed.
- Share the survey and watch responses arrive encrypted and anonymous.
- Run AI analysis to pull out themes and sentiment, then export or sync results to your other tools.

Key features
End-to-End Encryption
Every response is encrypted on the respondent's device before it travels to BlockSurvey, and only the account owner holds the key to decrypt it. This end-to-end encryption means a breach on the company's servers exposes scrambled data rather than readable answers. For teams handling medical, legal, or personal information, this changes what a leak would actually cost.
AI Survey Creation
You describe the survey you need in plain language, and AI survey creation writes, refines, and structures the questions for you. It suggests question types, adds skip logic, and can translate a survey into more than 100 languages. The goal is to skip the blank-page stall and get a working draft in seconds.
Campaign Delivery
BlockSurvey sends surveys through email and SMS campaigns, and shares them by link, QR code, widget, or website embed. You can schedule reminders and multi-step follow-ups so people who have not replied get a nudge. Running every channel from one place saves the juggling act of separate tools.
AI Analysis
Rather than exporting to a separate analytics suite, you get AI thematic analysis, sentiment scoring, and instant summaries inside the platform. The analysis runs on encrypted data, which keeps the privacy promise intact. For teams without a data analyst, this shortens the gap between collecting answers and understanding them.
White Label and Custom Domains
Organizations can run custom domain surveys on their own domain, add their logo and colors, and remove BlockSurvey branding. This makes the survey look like part of your product rather than a third-party form. Enterprise adds full white label, SSO, and unlimited seats.
Compliance Toolkit
The platform ships with HIPAA and GDPR compliance options, SOC 2 and ISO 27001 certification, and FERPA support for education. Team plans include a data processing agreement, and HIPAA plans include a business associate agreement. That paperwork matters when a legal or procurement team has to sign off.
Integrations
Responses sync with tools like Google Sheets, Microsoft Excel, Airtable, HubSpot, Power BI, Zendesk, and Slack through more than 100 integrations. Workflows and reporting land where your team already works. Payment, signature, and file upload question types also feed those downstream systems.
Pros and cons
Pros
- End-to-end encryption means even BlockSurvey cannot read your responses.
- No trackers, cookies, or ads by default, so respondent data is not resold.
- AI handles survey writing and analysis, which cuts setup and cleanup time.
- HIPAA, GDPR, SOC 2, and ISO 27001 cover teams in regulated fields.
- More than 100 integrations push responses into existing workflows.
Cons
- Pricing starts at $39 per month, far above free form tools, so casual users may overpay.
- The cheapest plan caps responses at 6,000 per year, which busy teams will hit.
- There is no public REST API, so deep custom automation from your own code is limited.
- It runs in the browser only, so there is no native desktop or mobile app to install.
