You can buy knowledge base software today, with a published price and no sales call, starting at $29/month. Helpable (gethelpable.com) is a self-service help center platform for SaaS teams and small businesses, built with flat-rate public pricing and a 7-day free trial that requires no credit card. If you are tired of filling out "contact sales" forms just to find out what a support hub costs, this guide compares every major option by what they actually charge in 2026.
What Is Knowledge Base Software?
Knowledge base software lets you publish searchable help articles, FAQs, and guides so customers can solve problems without contacting your team. A good help center reduces support volume, improves customer satisfaction, and works around the clock. The best FAQ software also includes analytics, AI answers, and schema markup so articles rank in search results.
Why Opaque Pricing Is a Real Problem
When a vendor hides pricing behind a demo request, it costs you time and often signals that prices are negotiable, meaning you may pay more than a comparable buyer. Gartner research from 2024 found that 77 percent of B2B buyers said vendor websites that required a sales conversation before sharing pricing extended their purchase cycle by at least two weeks. For a self-service documentation tool, that friction is ironic.
Opaque pricing also makes it hard to budget. A team evaluating 4 or 5 KB software options cannot do a fair comparison when 2 of them hide their numbers. The vendors below are ranked from most to least transparent.

Helpable: Flat Rate, No Seat Fees, Live in 15 Minutes
Helpable publishes 3 plans with no hidden fees and no per-seat charges on the Business and Scale tiers. The Pro plan costs $29/month, delivers 2,500 AI answers per month, and supports 1 author, which suits solo founders or small ops teams. The Business plan costs $79/month, handles 10,000 AI answers per month, and includes unlimited users. The Scale plan costs $199/month, covers 40,000 AI answers per month, and adds SSO.
Every plan includes a searchable help center on a custom domain with free SSL, the Calli AI assistant (which answers questions from your published articles without any model training), an embeddable widget via a single script tag, automatic schema markup for FAQs and how-to guides, built-in NPS and CSAT surveys, and support for 50-plus languages with automatic hreflang tags. You can read a deeper breakdown of each tier in the Helpable pricing guide for every plan.
"Teams that switch from per-seat FAQ software to flat-rate pricing save an average of 40 percent on their annual help center budget."
Helpable is built in Europe, is GDPR-native, and has a Data Processing Agreement available on request. The self-service portal goes live in roughly 15 minutes.
Where Helpable Is NOT the Right Fit
Helpable is not the right choice if you need a ticketing system with SLA management (Zendesk or Freshdesk handle that), live chat with human agents, a community forum, or developer documentation with code versioning. Zapier integration is in development but not available in 2026. If your workflow depends on Zapier automations today, look at Freshdesk or HelpScout while you wait. SSO is locked to the $199/month Scale plan, so smaller teams on Pro or Business will not have it.

Document360: Transparent Pricing, But the Free Plan Is Gone
Document360 removed its free plan in November 2024. Paid plans now start at roughly $149/month, charged per editor seat above a base threshold. The platform is feature-rich, with version control, category managers, and a reviewer workflow. However, the per-seat model means a team of 5 editors can quickly reach $400 to $600 per month, which is steep for a pure knowledge base. Document360 does not require a sales call, so its pricing is at least visible.
Helpjuice: Flat Rate but Expensive
Helpjuice starts at about $200/month for up to 4 users. That flat rate is transparent and includes unlimited articles, a custom domain, and basic analytics. The interface is clean and the search is fast. At $200/month as the entry point, though, it costs nearly 7 times more than Helpable's Pro plan for a comparable feature set on a small team. Helpjuice does not push you into a sales call, which is a genuine advantage over enterprise vendors.
HelpScout: Per-Seat With a Visible Price
HelpScout charges roughly $50 per user per month and publishes that price openly. It bundles a help center (called Docs) with shared inbox and a basic beacon widget. If you already use HelpScout for email support and want to add a self-service portal, the bundled approach can be cost-effective. For a team of 3 paying $150/month total, it competes reasonably with Helpable's Business plan at $79/month. The trade-off is that you pay for every user seat, and the AI features are not as tightly integrated as Calli.
Zendesk: Powerful but Expensive and Sometimes Requires a Call
Zendesk Suite Professional costs approximately $115 per agent per month. For a 10-person support team, that is roughly $1,150/month, which is nearly 4 times the cost of Helpable's Scale plan for the same headcount. Zendesk is a full ticketing, SLA, and helpdesk platform, so the comparison is not entirely apples-to-apples. If you need SLA management and multi-channel ticketing, Zendesk justifies the cost. If you only need a customer-facing knowledge base with AI answers, it is significant overkill.
Intercom Fin AI: Pricing That Scales Unpredictably
Intercom's Fin AI charges approximately $0.99 per resolved conversation. That sounds affordable until you have 5,000 resolved conversations in a month, which generates a $4,950 bill. A busy SaaS company with 10,000 monthly AI resolutions would pay around $9,900 per month for the AI layer alone, not counting the base Intercom subscription. Helpable's Scale plan handles 40,000 AI answers per month for a flat $199, which is a fundamentally different pricing model for teams that value predictability.
"Flat-rate AI pricing matters: at 10,000 monthly conversations, per-resolution models can cost 50 times more than flat-rate alternatives."
HubSpot Service Hub: Contact-Based Pricing, Not Transparent
HubSpot Service Hub Professional costs about $450/month and is priced on marketing contacts rather than support agents. The knowledge base feature is capable and integrates tightly with HubSpot CRM. If you already pay for HubSpot's Marketing or Sales hubs, adding Service Hub can be efficient. If you only want a self-service support hub with no CRM dependency, $450/month is hard to justify when dedicated FAQ software covers the same use case at a fraction of the price.
GitBook: Developer Docs, Not Customer Support
GitBook starts at roughly $6.70 per user per month and is genuinely good for developer documentation, API references, and internal wikis. It is not designed to be a customer-facing help center. There is no built-in AI widget for end users, no CSAT survey layer, and no automatic FAQPage schema for SEO. If your use case is internal documentation or a developer portal with code versioning, GitBook is worth evaluating. If your use case is customer self-service, a dedicated documentation tool like Helpable fits better.
How to Choose Without a Sales Call
- Define your primary use case: customer self-service, internal wiki, developer docs, or ticketing.
- Count your authors, not your readers. Per-seat tools charge by editors, not by the customers who read articles.
- Estimate your monthly AI volume. If you expect more than 5,000 AI interactions per month, per-resolution pricing gets expensive fast.
- Check whether the vendor publishes pricing. If they do not, budget an extra 2 weeks for the sales process.
- Start a free trial before committing. Most good tools, including Helpable, offer at least 7 days without a credit card.
"Buyers who trial KB software before purchasing are 3 times more likely to report satisfaction with their choice after 6 months."
Frequently Asked Questions
Does Helpable require a sales call to get pricing?
No. All 3 Helpable plans are listed publicly at gethelpable.com. The Pro plan is $29/month, Business is $79/month, and Scale is $199/month. You can start a free trial without speaking to anyone.
Which knowledge base tools charge per seat?
Zendesk ($115/agent/month), Freshdesk ($49/agent/month), HelpScout ($50/user/month), GitBook ($6.70/user/month), and Document360 all charge per seat or per editor. Helpable charges a flat monthly rate with unlimited users on the Business and Scale plans.
What happened to Document360's free plan?
Document360 removed its free plan in November 2024. Their cheapest paid tier now starts at approximately $149/month. Teams that relied on the free plan needed to migrate or pay for a new subscription.
Is Helpable suitable for large enterprise teams?
Helpable works well for teams of any size that need a customer-facing self-service portal, but it does not include ticketing, SLA management, or live agent chat. For enterprise support operations that need those features, Zendesk or Freshdesk are better fits. SSO on Helpable is available only on the Scale plan at $199/month.
Can I set up a help center without a developer?
Yes. Helpable publishes a help center on a custom domain with free SSL, and the embeddable widget installs via 1 script tag. Most teams go live in about 15 minutes without writing any code.
How does Helpable's AI compare to Intercom Fin?
Helpable's Calli AI answers customer questions from your published articles without any model training required. Intercom Fin is more sophisticated and can handle multi-step conversations, but it charges approximately $0.99 per resolved conversation. At 5,000 monthly resolutions, Intercom Fin costs around $4,950 versus $199 for Helpable's Scale plan.
What are the real limitations of Helpable?
Helpable does not offer ticketing, SLA management, live chat with human agents, a community forum, Zapier integration (in development as of 2026), or developer documentation with code versioning. The Pro plan at $29/month supports only 1 author, so multi-author teams need the Business plan at $79/month.
Is there a free trial for Helpable?
Yes. Helpable offers a 7-day free trial with no credit card required. You can start immediately at gethelpable.com and have a working help center live within 15 minutes.
