How Zefi works
Your feedback sources, enriching each other automatically.
Most tools dump everything into a single bucket and call it 'centralized.' We do something harder: we connect your sources so they inform each other. Cleaner data, less noise, and a system that gets sharper with every integration, without losing the big picture.
"Zefi helps us turn customer feedback scattered through many channels into one source of truth. It works as our VoC control tower"
Yujia Cao
Head of Research & Insights @ Kiwi.com
Structure the unstructured data. Bridge qual & quant and get the why behind your customers' interactions.
Bridge qualitative and quantitative. Control the logic of the data that feeds your agents — so you can build trustable automations even for large, complex pipelines. We don't just categorise feedback. We help you own the taxonomy so your AI-driven workflows stay accurate, auditable, and scalable.
"Zefi enables us to create custom dashboards to identify areas for improvement and valuable insights. It's outstanding."
Claire Pauze
Customer Operations Team Leader @ Qomodo
Stay ahead of your customers. Act proactively on their feedback thanks to a company-wide operating system.
Close the loop with a structured, best-in-class framework to monitor, strategise, and share across your org. Proactively manage workflows for cutting operative costs, improving experience, and finding growth opportunities before your customers have to tell you twice. Stay ahead. Act proactively. Move and prove your customers KPIs.
"We changed our approach towards customer feedback from reactive to proactive. Zefi has been instrumental in this change."
Sonia Ferrón Sáenz
Customer Experience & Quality Manager @ Wallapop

Frequently Asked Questions About Zefi AI Assistant & Zefi Features
Does it work across all connected sources?
Yes.
That’s one of Zefi’s core strengths.
Zefi works across all your connected data sources, such as:
- Surveys
- Support tickets
- NPS responses
- App reviews
- Social or community feedback
It unifies everything into a single layer, so you can structure your data, extract insights and ask questions from your entire customer voice. No silos.
How fast are AI Assistant responses?
When using Zefi AI assistant, you can get answers on the voice of your customers in a few seconds.
Responses are designed to be near real-time.
Most queries return in seconds, even when analyzing large volumes of feedback across multiple sources. This makes it easy to:
- Explore follow-up questions interactively
- Use Zefi in live meetings or reviews
- Quickly validate hypotheses without waiting on reports
When should I use Zefi instead of building in-house?
You could build internally, but most teams underestimate the complexity.
Zefi is purpose-built for customer feedback analysis, which means you get:
- Pre-built pipelines for messy, unstructured CX data
- Taxonomy control and tagging tuned specifically for VoC, support quality, and sentiment analysis
- Fast time to value (days, not months)
- Continuous improvements without maintenance overhead
If customer insight is critical but not your core product, Zefi lets your team focus on acting on insights instead of building infrastructure. We are your CX infrastructure.
Do you support multiple languages?
Yes.
Zefi is built for global teams.
We support feedback in more than 100 languages and can analyze them together in a unified way. This means you can:
- Aggregate insights across regions
- Identify trends regardless of language
- Ask questions in one language and get answers based on all your data
No need to manually translate or segment your datasets.
How accurate are the AI Assistant answers? How do you handle hallucinations?
Accuracy is critical when working with customer data.
Zefi minimizes hallucinations by grounding every answer in your actual data. The AI doesn’t “guess”, it retrieves and analyzes real customer feedback before generating a response.
We also:
- Provide traceability, so you can drill down into the underlying feedback behind each answer
- Continuously evaluate and improve accuracy on real-world CX use cases
- Apply safeguards to avoid unsupported or low-confidence claims
The result is answers you can trust and verify when needed.
What is the AI Assistant, What can I ask it?
Zefi’s AI Assistant is your always-on analyst for customer feedback.
Instead of manually digging through surveys, support tickets, or reviews, you can simply ask questions in plain language. For example:
- “What are the main complaints about onboarding?”
- “Why are customers churning this quarter?”
- “Summarize negative feedback about our latest release”
- “Are support agents improving over time?”
The Assistant understands context across all your data sources and gives you clear, actionable answers in seconds, no SQL required.
Can I integrate Zefi with my current tools?
Yes, we have a set of more than 100 native integrations and you can connect all your tools in just a few clicks. The onboarding is quick and the Zefi Customer Success team will take care of all of it. In a couple of days you'll have all your customer interactions centralized into Zefi. You can see a list of the main integrations directly from here.

Customer Experience, Voice of Customer and QA teams use Zefi to surface answers to the most pressing customer questions, identify the most critical pain points to solve, and validate what customers care about the most.
How much montly feedback should I have to get value from Zefi?

To remove any doubts you might still have.
