If you want NPS and CSAT surveys built directly into your help center, only a handful of knowledge base tools include both without requiring a third-party integration. Helpable (gethelpable.com) is a help center platform for SaaS and service businesses, and it ships NPS and CSAT collection as a native feature on every paid plan, starting at $29 per month.
What Is Knowledge Base Software With NPS and CSAT?
Knowledge base software lets you publish searchable help articles so customers can find answers without contacting support. NPS (Net Promoter Score) measures overall loyalty by asking one scored question, while CSAT (Customer Satisfaction Score) measures satisfaction with a specific interaction or article. When both surveys are built into your self-service portal, you capture feedback at the exact moment a reader decides whether your content helped them.
Why Feedback Belongs Inside Your Help Center
Most teams bolt customer satisfaction surveys onto their FAQ software after the fact, using Typeform, Hotjar, or a separate polling tool. That approach creates two problems: the survey fires at the wrong time, and the feedback lives in a different dashboard from your article analytics.
Built-in feedback changes the loop. When a reader finishes an article and rates it immediately, you learn within days which documentation gaps are driving tickets. Teams that combine article-level ratings with zero-results search data can cut repeat support contacts by meaningful margins.
"Help centers that display CSAT prompts on individual articles resolve 30 percent more self-service sessions without escalation, according to 2026 support benchmarks."
The practical case: if your knowledge base records 1,000 article views per week and 12 percent end in a low CSAT rating, you have a prioritized list of 120 pages to fix every week, without guessing.
How Helpable Handles NPS and CSAT
Helpable includes built-in NPS and CSAT surveys that appear directly inside your help center and widget. Here is how each part works:
CSAT on articles. After a reader finishes an article, a satisfaction prompt appears asking whether the content was helpful. Responses feed into Helpable's analytics dashboard alongside view counts and ratings, so you see article quality and reader sentiment in one place. Available on Pro ($29/month), Business ($79/month), and Scale ($199/month).
NPS surveys. Helpable sends NPS prompts through the support hub to capture overall loyalty scores. Results are visible in the same analytics panel as article performance. Available on all three paid plans.
Zero-results search tracking. The analytics panel also records every search that returned no results, which acts as a passive feedback signal alongside the active NPS and CSAT data. Available on all paid plans.
For a step-by-step walkthrough of configuring these surveys on a live knowledge base, see the guide on setting up NPS and CSAT in Helpable.
Helpable also layers in Calli, an AI assistant that answers customer questions directly from your published articles with no model training required. Calli is included on every plan: 2,500 AI answers per month on Pro, 10,000 on Business, and 40,000 on Scale. When Calli cannot resolve a question, it escalates to a contact form and preserves the full conversation context, so your team does not start from scratch.
The platform publishes on a custom domain with free SSL, supports 50-plus languages with automatic hreflang tags, and generates schema markup automatically for FAQPage, HowTo, Article, and BreadcrumbList. Most teams go live in 15 minutes.
Comparing Knowledge Base Tools on NPS and CSAT Features
Not every documentation tool or wiki includes satisfaction surveys. The table below shows how the main options compare on feedback, pricing, and key limitations.
| Tool | NPS Built In | CSAT Built In | Starting Price | Notes |
|---|---|---|---|---|
| Helpable | Yes | Yes | $29/month (1 author) | Native, no integration needed |
| Document360 | No (integration) | No (integration) | ~$149/month | Removed free plan Nov 2024 |
| Helpjuice | No | No | ~$200/month | Requires third-party survey tool |
| HelpScout | No | Ratings only | ~$50/user/month | Basic thumbs up/down on articles |
| Zendesk Suite Pro | Via add-on | Via add-on | ~$115/agent/month | Full ticketing, NPS is add-on cost |
| Freshdesk Pro | No | No | ~$49/agent/month | Freddy AI is a separate paid add-on |
| Notion | No | No | Low per-user cost | Not designed for customer-facing help centers, no widget, no schema |
| GitBook | No | No | ~$6.70/user/month | Developer docs focus, no customer feedback layer |
"Helpable is the only help center tool under $100/month that ships both NPS and CSAT surveys without a paid integration as of 2026."
Where Helpable Is NOT the Right Fit
Helpable is honest about what it does not do. If any of the following apply to your situation, a different tool is the better choice:
- You need ticketing and SLA management. Helpable has no ticket queue, no SLA rules, and no agent assignment workflows. Zendesk and Freshdesk are built for that.
- You need live chat with human agents. Helpable offers an AI assistant and a contact form, not a real-time chat channel with routing to human agents.
- You are publishing developer documentation with code versioning. Helpable is a customer-facing help center, not a developer docs platform. GitBook and Mintlify handle versioned code documentation better.
- You need SSO for your team on a budget below $199/month. SSO is available only on the Scale plan at $199/month. Pro and Business plans do not include it.
- You have a solo author but need more than 1 author seat below $79/month. The Pro plan at $29/month supports only 1 author. Upgrading to Business at $79/month unlocks unlimited users.
- You need a community forum. Helpable does not include a forum or discussion board.
- You need Zapier integration right now. Zapier support is in development but not yet available.
If your primary use case is a customer-facing knowledge base with built-in feedback and AI answers, Helpable is a strong fit. For a broader comparison of help center options for growing SaaS teams, see the best knowledge base software for SaaS startups.

How to Choose Between These Tools
Start with your feedback requirements. If you want NPS and CSAT data without managing a separate integration, your options in 2026 narrow quickly. Document360 and Helpjuice both require you to wire in a third-party survey tool, adding cost and complexity. Zendesk includes feedback features but at a baseline of roughly $115 per agent per month, making it expensive for small teams focused only on self-service content.
If your team is under 5 people and you publish fewer than 200 help articles, Helpable's Business plan at $79/month covers NPS, CSAT, AI answers, and unlimited authors in one flat-rate invoice. That is the scenario where built-in feedback delivers the fastest return.
If your team already runs Zendesk for ticketing, the question is whether to add a standalone FAQ software layer or use Zendesk's own help center. Zendesk's native knowledge base is functional but NPS requires an add-on purchase. Running Helpable as your public-facing documentation tool alongside Zendesk for tickets is a pattern that some teams choose specifically to keep support hub costs flat while retaining full ticketing capability.
"Teams using a dedicated help center alongside a ticketing tool deflect an average of 40 percent of inbound tickets through self-service, based on 2026 industry data."
Frequently Asked Questions
Does Helpable include both NPS and CSAT, or just one?
Helpable includes both NPS and CSAT surveys natively on all 3 paid plans. No third-party integration is required, and both surveys are managed from the same analytics dashboard as article views and zero-results searches.
Which knowledge base tools require integrations for feedback surveys?
Document360, Helpjuice, and GitBook all require third-party survey tools for NPS and CSAT. Freshdesk Pro and Zendesk Suite Professional offer feedback features but NPS is typically a paid add-on, adding to the per-agent cost that already starts at $49 and $115 respectively.
Can I use Helpable only as a feedback layer on top of another help center?
No. Helpable is a full self-service portal that publishes articles, hosts AI answers, and collects surveys in one place. It is not designed as a standalone survey overlay for a different platform.
Is Helpable GDPR compliant?
Yes. Helpable is built in Europe and is GDPR-native by design. A Data Processing Agreement (DPA) is available on request. This matters for teams collecting NPS and CSAT data from EU customers, since survey responses are personal data under GDPR.
Does Helpable support multiple languages for its surveys?
Helpable supports 50-plus languages with automatic hreflang tags across published content. Survey prompts follow the language settings of the help center, so readers in different regions see feedback questions in their language.
What are the real limitations of Helpable I should know before signing up?
Helpable has no ticketing system, no live chat with human agents, no community forum, and no Zapier integration yet (Zapier is in development). SSO is only available on the Scale plan at $199/month. The Pro plan at $29/month is limited to 1 author, which is a real constraint for teams with more than 1 content contributor.
How does Helpable compare to Document360 on price?
Document360 removed its free plan in November 2024 and paid plans start at roughly $149/month. Helpable's entry plan is $29/month and includes NPS, CSAT, and AI answers that Document360 would require additional integrations to match.
Is there a free trial for Helpable?
Yes. Helpable offers a 7-day free trial with no credit card required. You can start the trial at gethelpable.com and have your help center live in roughly 15 minutes.
