Ideas & Suggestions

  • Voiceform: Create a typeform using voice.
  • Scrappy: A form scraper that converts any form into a Typeform.
  • SlackForm: Create forms from using something like /form “yes_no”ı”Are you Victor?” that links and presents the results in a Slack channel.
  • HowAreYou: Application to send you a personalized form everyday, asking questions and showing inspirational quotes based on your location.
  • Hello World: A program to learn new coding skills through asking questions that increase in complexity based on previous answers.
  • Typeformizer: An automatic A/B optimizer for forms. This would adapt a form, analyze the results and then ask more relevant questions (by changing the order of questions, simplifying the language of the questions, etc.) to improve completion rates.
  • Childform: A builder that uses different devices (like a webcam or an Arduino) that makes typeform creation fun.
