What Is an Online Form Builder?
An online form builder is a web-based tool that lets you create forms — surveys, registration pages, feedback forms, contact forms, quizzes — without any coding. You add questions, choose answer types, configure settings, and publish a shareable link or embed code.
The best free form builders go further: they collect responses in real time, display analytics automatically, and let you export or share results. Untold Opinion adds AI generation and sentiment analysis on top of that.

Key Features to Look for in a Free Form Builder
Multiple question types
Multiple choice, checkboxes, dropdowns, short text, long text, rating scales, NPS, date pickers, and file uploads.
Real-time response tracking
See responses as they come in — no waiting for a report to be generated.
Embed on any website
A script tag or iFrame embed so the form lives on your own site, not a third-party URL.
Mobile-responsive design
Forms that work perfectly on phones — where most respondents will fill them in.
No response limits
Free tools that cap responses at 100 are useless for real projects. Look for unlimited responses.
AI-powered creation
Describe your goal and let AI write the questions — saving hours of form design time.
