Document360 vs HelpKit vs Helply: Features and Pricing Compared (2026)

Key Takeaways

• Helply is more than a knowledge base. The same AI that drafts and resolves tickets also writes help articles, spots knowledge gaps, and flags revenue signals like churn and upsell.
• Document360 is the strongest fit for regulated enterprises that need version control, granular permissions, and SSO, but it moved to quote-only pricing in late 2024, has no free tier, and now requires a sales call.
• HelpKit is the cheapest and fastest to launch, at $15 to $79 per month per site, but it is fully dependent on Notion and its AI only answers questions. It never writes articles.
• Only Helply has a real free tier: the full support platform, with unlimited seats and every channel, is free forever, and you pay only when AI produces an outcome, such as $2.99 per drafted article or $0.50 per resolved ticket.
• For most B2B software teams, Helply wins because it turns support into documentation and revenue automatically, instead of adding another tool you have to feed by hand.

Your help center is out of date the moment you finish writing it. A feature ships, the screenshots go stale, three tickets come in asking the same question, and nobody has time to write the article that would have deflected them. So you go shopping for a knowledge base tool, and the choice feels rigged from the start.

On one side sits Document360, powerful and expensive, where one reviewer warns you now have to "book a Zoom just to cancel." On the other sits HelpKit, cheap and pretty, where the pitch is "great tool, if you already live in Notion."

Both leave you doing the one thing you wanted to stop doing: writing every article yourself.

This comparison breaks down Document360 vs HelpKit vs Helply on real pricing, AI features, and what rusers report, so you can pick the right knowledge base software without sitting through a sales demo.

Each tool wins on something, and this guide is clear about where, and about where Helply pulls ahead of both.

Document360 vs HelpKit vs Helply: Which Knowledge Base Is Best?

Choose Document360 if you need enterprise governance, like version control, approval workflows, and SSO, and can accept hidden pricing and a heavier editor.

Choose HelpKit if your team already runs on Notion and wants a cheap, attractive help center it will maintain by hand.

Choose Helply if you want AI to write and maintain the docs on a free support platform, and turn the same tickets into revenue.

Document360: Enterprise Structure Behind a Sales Quote

Document360, built by Kovai.co, is a structured documentation platform aimed at mid-market and enterprise teams.

It is a dedicated system for building public and private knowledge bases, with the kind of versioning, permissions, and compliance that large organizations require.

If your buyer is an IT or CX leader in a regulated industry, this is the tool built for them.

Document360 Features

• Structured authoring. Markdown and WYSIWYG editors, categories and subcategories, version history, and an approval workflow builder keep large documentation sets under control.
• Eddy AI (included). The AI Writing Agent turns video, audio, text, or a prompt into a draft article with auto-generated screenshots, and Ask Eddy answers reader questions from your content.
• AI Premium Suite (add-on). Screen capture, step-by-step guides, interactive demos, and video recording are sold as a separate tier on top of your plan.
• Governance and security. Role-based access control, private reader accounts, SSO with SCIM and SAML, audit logs, SOC 2 Type II, ISO 27001, and GDPR support cover enterprise requirements.
• Scale features. Localization across 50-plus languages, decision trees, a ticket deflector, and around 25 integrations including Zendesk, Freshdesk, and Intercom.

Document360 Pricing

Document360 no longer publishes prices. As of 2026, the Document360 pricing page is a quote-only configurator, there is no free tier (only a 14-day trial), and every quote scales by editors, projects, languages, SSO, and AI usage.

Several reviewers on legacy plans report renewals that "nearly doubled." Expect a sales conversation before you see a number.

Document360 Pros

• Purpose-built for documentation. Reviewers who write docs full time praise how the platform is "clearly built for documentation, not some generic tool trying to do everything."
• Strong customer success. Support scores 4.8 on Capterra, and users describe onboarding help as "incredibly proactive."
• Deep customization. Teams can add custom CSS, HTML, and JavaScript to shape the portal without hitting a wall.
• AI that saves writing time. The summarizer and Writing Agent help larger teams bulk-manage articles and cut repetitive work.

Document360 Cons

• Cancellation friction. A Trustpilot reviewer reports being asked for a Zoom meeting to cancel, and another says their account was deleted within minutes of declining a renewal, with no content export.
• Cost and price hikes. Reviewers call it "very expensive for what they offer," and legacy customers report renewal quotes that roughly doubled.
• Editor bugs. One technical writer describes callouts that will not wrap selected text: "I have around 10 callouts per article" and had to fix them line by line.
• Performance and search. Users note lag on long documents, and search that misses relevant articles unless keywords match exactly.

Document360 holds 4.7 on G2 across 524 reviews and 4.7 on Capterra across 292, but only 2.2 on Trustpilot.

Where Document360 Beats HelpKit

For a team that has outgrown a wiki, Document360 wins on almost everything HelpKit cannot touch.

It gives you real version control, approval workflows, and audit logs, so a compliance-minded team can prove who changed what and when.

It scales to 50-plus languages and multiple projects, where HelpKit tops out at low seat counts and a handful of languages. It has SSO, SCIM, and granular permissions, while HelpKit offers little more than password protection.

And it is a standalone system, so it does not fall over the day your Notion workspace has a bad sync. If governance is the deciding factor, Document360 is the safer tool.

Best for: large, regulated teams that need heavy governance and have the budget and patience for enterprise procurement.

HelpKit: A Fast, Cheap Help Center Trapped in Notion

HelpKit, built by solo founder Dominik Sobe, turns a Notion workspace into a hosted, branded help center. You write in Notion, and HelpKit publishes a fast, good-looking site with a custom domain.

For a small team already living in Notion, it removes the need to learn a new content system. That is the entire appeal, and for the right team it is a strong one.

HelpKit Features

• Notion as your CMS. You write and edit articles in Notion, and HelpKit renders them as a cached, hosted help center that loads far faster than a public Notion page.
• Embeddable widget and mobile SDK. A searchable help widget drops onto any site, and a React Native SDK puts the help center inside your app.
• Branding and search. Custom domain with SSL, logos, colors, custom CSS and JavaScript, full-text search, and analytics with search-intent insights.
• HelpKit AI (add-on). An optional chatbot answers questions from your Notion articles using OpenAI, with citations and a chat-history dashboard.

HelpKit Pricing

HelpKit charges per site, billed annually:

• Starter at $15 per month
• Business at $31 per month
• Professional at $79 per month, with monthly billing running higher

The HelpKit AI chatbot is a separate $49 per month add-on. There is a seven-day trial and no free-forever tier, and running multiple knowledge bases requires custom pricing.

Note that older "$99 for 10 seats" figures floating around are stale; current seats are 1, 3, and 5 by tier.

HelpKit Pros

• Live in 30 minutes. Users report following a setup video and having "a new help center online" inside half an hour.
• Notion-native workflow. For teams that already use Notion "for literally everything," writing docs in a tool they know is the main draw.
• Fast and attractive. One user who tried Super.so and Potion first said "they don't even come close, not in speed, not in structure."
• Responsive founder. Reviewer after reviewer mentions the founder answering questions within hours.

HelpKit Cons

• Total Notion dependency. No Notion, no HelpKit, and Notion quirks leak through. One user notes a teammate "accidentally change table properties and this can break integration."
• The AI only answers. HelpKit AI responds from articles you already wrote. It cannot generate documentation from tickets or recordings.
• No support workflow. There is no ticketing or inbox. HelpKit can only embed a third-party chat widget like Intercom or Crisp.
• Paywalled basics. One reviewer renamed a collection, the old link broke, and setting up a redirect required upgrading to the Professional plan.

Ratings are strong but thin. HelpKit holds 5.0 on G2 across 11 reviews and 5.0 on Product Hunt across 9. That is a small, self-selected sample, so read it as "loved by its early users," not as a broad verdict.

Where HelpKit Beats Document360

For a small team, HelpKit wins on the things Document360 makes painful. Pricing is public and cheap: you can start at $15 a month and know exactly what you owe, with no sales call and no surprise renewal.

Setup is measured in minutes, not an implementation project, because your team writes in Notion instead of learning a new editor.

There are no callout bugs or long-document lag to fight, and cancelling does not require a Zoom meeting.

For a startup that wants a clean help center this week, HelpKit is the simpler, cheaper choice.

Best for: Notion-native startups and small teams that want a cheap, elegant help center and are content to write and maintain every article themselves.

Helply: The Knowledge Base That Writes Itself

Helply is an AI-native B2B support platform, and its knowledge base is one part of a larger system. That framing matters for this comparison.

Where Document360 and HelpKit are documentation tools, Helply treats every support conversation as fuel: the same AI that reads a ticket can resolve it, draft a reply, write the help article that prevents the next one, and flag a churn risk hiding in the message.

For a knowledge base buyer, that means you no longer hand-write the docs; they come out of the support work your team already does. The comparison is lopsided: Helply keeps its knowledge base current for you, while Document360 and HelpKit leave that work to you.

Helply Features

• AI Recorder. Record a product walkthrough once in the browser, and Helply transcribes the audio, captures the screenshots, writes the captions, and publishes a searchable article and video in one pass.
• Article Creation from tickets. The AI reads recurring questions across your support channels and drafts the help articles that answer them, so your help center grows from real demand instead of guesswork.
• Knowledge gap detection. Helply scans tickets for questions your docs do not answer, flags the missing or outdated articles, and drafts the fixes, so the knowledge base repairs itself.
• Support Intelligence. Ask Helply anything across tickets, accounts, billing, and product data in plain language, and get an answer with sources instead of digging through threads.
• Revenue and product signals. Every ticket is scanned for churn risk, upsell intent, competitor mentions, and feature requests, each routed to the CSM, AE, or product owner who needs it.
• Full channel coverage. Slack Connect, Microsoft Teams, Discord, email, in-app chat, SMS, WhatsApp, a customer portal, and an API all feed the same knowledge base and context layer.

Helply Pricing

Helply's support platform is free forever, with unlimited seats, every channel, ticketing, and the knowledge base included at no cost.

You pay only when AI delivers an outcome, and each outcome is priced on its own.

For knowledge base work, that means;

• $2.99 per created article
• $2.99 per article from the AI Recorder
• $0.50 per knowledge gap identified

On the support side;

• Drafted replies are $0.25
• Resolved tickets are $0.50
• Revenue and product signals, such as churn detection, upsell opportunities, and competitor monitoring, are $2.99 each

Spending caps are built in, so costs stay predictable. See the full model on the outcome pricing page.

Helply Pros

• It creates the documentation. The AI Recorder and Article Creation turn recordings and tickets into finished articles with screenshots and video, so nobody writes from a blank page.
• It fixes its own gaps. Automatic gap detection means your help center gets more complete every week without a content backlog.
• It is the support workflow, not a bolt-on. Docs, tickets, and account context share one system, so an article, a resolution, and a churn alert all come from the same conversation.
• No Notion lock-in and a real free tier. Helply runs on its own editor with imports from your existing tools, and the helpdesk itself costs nothing.

How to Choose Knowledge Base Software

Once you strip away the feature lists, three questions decide this category.

• Do you want to write the docs, or have AI create them? If you are fine writing every article by hand, HelpKit and Document360 both work. If you want documentation produced from your tickets and recordings, only Helply does that today.
• How much pricing transparency and flexibility do you need? Document360 hides its price behind a quote. HelpKit is cheap and public but per site. Helply is free at the helpdesk layer and bills per outcome, so a slow month costs less.
• Should the knowledge base connect to your support workflow? HelpKit is documentation only, and Document360 connects through integrations. Helply is the support platform itself, so docs and tickets never drift apart.

Answer those three questions and the pick is clear.

Final Verdict

For most B2B software teams, Helply is the strongest choice, because it does the work the other two hand back to you. It writes documentation from your tickets and recordings, repairs its own gaps, and runs on a free support platform that also turns those conversations into revenue signals.

Document360 remains the right call for large, regulated organizations that need deep governance and can navigate enterprise procurement.

HelpKit stays a smart, low-cost pick for Notion-native teams that only need a simple, attractive help center. The difference is who does the writing, and with Helply, the answer is the AI.

Stop writing help articles by hand and let AI build your knowledge base from tickets you have already answered.
