Want to know if your customers would actually recommend you, before they quietly stop buying? One well built question can tell you. The NPS Survey Builder writes a complete Net Promoter Score survey around your product and channel, so you measure loyalty properly instead of guessing from a handful of reviews and a gut feeling.
Short answer: The NPS Survey Builder is a free EizTools tool that writes a full Net Promoter Score survey for your brand. Set the channel and follow up style, and it returns the score question, smart follow ups, and thank you messages ready to send.
What is NPS Survey Builder?
The NPS Survey Builder is an online tool that creates ready to run loyalty surveys. You describe your product and audience, choose how the survey is delivered, and it returns the classic recommend question, a follow up that asks why, and thank you messages that fit the score. It works for email, in app, SMS, and website surveys, and it suits founders, product teams, and support leads who want a proper NPS program without designing every question by hand.
How Does NPS Survey Builder Work?
The tool runs in your browser and turns a short brief into a complete survey.
- Describe your product and audience in the prompt box, for example a project management app for small B2B teams.
- Pick an AI model from the selector at the top of the tool.
- Open the advanced options accordion and set the survey channel, tone, follow up style, and industry.
- Press Generate. The output card shows the model used, a live word count, and a reading time.
- Copy, Listen, or Download the survey as TXT, Word, or HTML, or open it in the editor to tweak the wording.
- Reopen past surveys from the activity history panel to keep each round consistent and comparable.
| Option | What it controls | Suggested starting point |
|---|---|---|
| Survey Channel | Where the survey is sent | Email for a first program, In-App for active users |
| Follow-Up Style | How you capture the reason for the score | Reason and Open Text, for usable feedback |
| Tone | The voice of the survey | Friendly, so more people finish it |
| Industry | The context it is written for | Your own, such as SaaS and Tech or E-commerce |
The rest fine tune it: toggle Segment the thank you by score, Ask for the reason behind the score, Invite promoters to review, or Offer follow up contact, and use Custom Instructions to name your product or the exact wording you prefer.
What a Good NPS Survey Includes
A strong NPS survey is short but complete. Look for these parts in the draft.
- ✅ The core question on how likely they are to recommend you, on a zero to ten scale.
- ✅ One open follow up that asks why they chose that score.
- ✅ A thank you that changes with a promoter, passive, or detractor.
- ✅ A clear next step, like a review invite for your happiest customers.
Tip Keep the wording identical each quarter so your scores stay comparable, and only change the survey when you genuinely want to measure something new.
When to Send It
Timing shapes both your score and how useful the answers are.
- A set time after onboarding, once a customer has really used the product.
- On a steady cycle, such as every quarter, to watch the trend.
- After a key milestone, not right after a support problem.
On EizTools every tool is free, works without sign up, and lets you switch between AI model families as you go. Once the responses are in, turn the raw scores and comments into a clear summary with the free Business Report Generator, so your team sees the trend and the reasons behind it at a glance.
