Scanning the code opens a mobile-optimized web page where they can instantly submit feedback or vote in a live poll, ensuring maximum accessibility and a low barrier to entry for high participation rates.
What happens to the QR code survey data after collection?
All data from QR code surveys is securely stored in your private PollQR database. You can access it at any time through your account dashboard to view, filter, and analyze responses. The platform includes tools to download your complete dataset as a .CSV file for archival or advanced analysis. Furthermore, you can configure automatic email notifications to alert you immediately when new feedback is submitted.
How does the AI sentiment analysis work?
PollQR's AI sentiment analysis automatically processes the text from open-ended survey responses. It uses natural language processing (NLP) to assess the emotional tone behind the words, classifying feedback as positive, negative, or neutral. Simultaneously, it identifies and extracts frequently mentioned keywords and phrases, grouping them into key themes. This allows you to quickly see not just what customers are saying, but also how they feel about specific aspects of your service or product.
What is the difference between the Pro subscription and pay-per-poll pricing?
PollQR offers flexible pricing to suit different needs. The Pro subscription is ideal for frequent presenters or trainers, providing a monthly allowance of live polls (e.g., 100 polls/month) for a recurring fee. The pay-per-poll (a-la-carte) option, at a cost like $2.99 per poll, is designed for users who require live polling infrequently, such as for a single annual conference or a few special presentations, offering cost-effectiveness without a subscription commitment.
