Eleven knowledge base platforms compared on price, internal articles, languages, AI answers and tickets, plus four SaaS help centers to learn from.
We make LiveAgent. It is listed first because it is ours, not because it won a test. Every tool, ours included, gets the same facts from its vendor’s own pages and its real drawbacks; which tool fits which team is our opinion. How we compared
Best knowledge base software for support teams
The best knowledge base software for most small support teams: Help Scout to start free, Zoho Desk for the lowest price with tickets, LiveAgent for a knowledge base in the same inbox as every channel with no AI fees, and Helpjuice or KnowledgeBase if you only need the knowledge base.
Knowledge base platforms compared: 11 tools side by side
What each tool is best for, whether it has agents-only articles, several knowledge bases and several languages, whether tickets and live chat are in the same tool, its starting price, and how it charges for AI answers.
How we compared
We read each vendor’s own pricing page, plan comparison and help articles from a US address on November 5, 2026 (links under sources). The starting price is the cheapest plan with a public knowledge base, for a new customer on annual billing. We did not buy paid accounts of the other tools, so we do not rate how their editors feel or how good their AI is. LiveAgent is first because it is ours; the others follow in alphabetical order, which is not a ranking. Where a page did not say something, the table says “Ask”.

Eleven knowledge base tools: what each is best for, agents-only articles, several knowledge bases, languages, tickets and live chat in the same tool, starting price, free plan or trial, and how it charges for AI
Starting prices in US dollars per month on annual billing for a new customer, per agent unless the note says otherwise, for the cheapest plan with a public knowledge base, as each vendor’s page showed them on November 5, 2026. A plan name in a cell: from that plan. “Ask”: the vendor’s pages do not say. Prices change; check the vendor’s page before you buy.
5 of 11 in one product
have tickets, live chat and the knowledge base in one product: LiveAgent, Help Scout, HubSpot, Intercom and Zendesk. HelpCrunch has chat and a shared inbox; the standalone tools link to a help desk instead.
2 ways to do languages
Translations inside one knowledge base, usually from a higher plan (Zendesk Suite Professional, Intercom Advanced, Freshdesk Pro), or one knowledge base per language (LiveAgent, Help Scout).
AI billed 6 ways
Per resolution, per outcome, per session, per pack of conversations, included from a higher plan, or not at all: LiveAgent charges no AI fees, you pay your own AI provider.
Ratings on G2 and Capterra
How each tool's users rate it on G2 and Capterra, the two largest software review sites. Ratings cover the whole product, not only its knowledge base, and say how happy customers are, not which tool fits you.

How to choose knowledge base software
Every tool here has an article editor, categories and search, so the features list decides less than you expect. These six questions decide more. To write the articles themselves, see how to create a knowledge base.
Six questions to ask
1Where do your customers ask?
2Who reads it?
3How many products or brands?
4Which languages?
5Will people find the articles?
6How is AI billed?
Where do your customers ask?
If they email and chat with you, a knowledge base inside your help desk lets agents put an article in a reply and shows customers matching articles while they write. A standalone tool needs an integration to do the same.
Who reads it?
Customers, your team, or both. Check whether agents-only articles come on your plan or need a higher one, or a second knowledge base with a password.
How many products or brands?
One knowledge base per brand or product keeps each one clear. Count how many the plan includes and what one more costs.
Which languages?
Some tools translate articles inside one knowledge base from a higher plan; others need one knowledge base per language. Price the languages you need today; the costs section has a worked example.
Will people find the articles?
Look for a search box on your website and next to the contact form, your own domain, and pages search engines can index, so customers find the answer before they write.
How is AI billed?
AI
An AI that answers from your articles is useful only once the articles are good. Then price it at your volume: per resolution, per outcome, per pack, or on your own AI provider.
What a knowledge base costs a support team
Each tool's cheapest plan with a public knowledge base, per month on annual billing at the price a new customer pays today, before taxes and AI. Help desks charge per agent, so the bill grows with your team; standalone knowledge bases charge a flat fee, but tickets and chats need a second tool.

Read the small print
The cheapest plan is not always the one you need
Help Scout's free plan stops at 5 users and 10 articles, and HelpCrunch Basic at one language.
LiveAgent's Starter plan is for up to 5 agents, so the 10 agents are on Team. Document360 is left out: it quotes prices on request.
Zendesk's lowest price, Support Team, has no help center; agents-only articles start on Suite Professional ($115 per agent).
HubSpot's knowledge base starts on Professional, with a one-time onboarding fee.
A flat-price knowledge base is cheap for a large team, but tickets and chat still need a help desk, and that bill comes on top.
Several brands in several languages multiply: 3 brands in 5 languages are 15 knowledge bases where each has one language (LiveAgent, Help Scout), or 3 help centers with translations on Zendesk Suite Professional, Intercom Expert or Zoho Desk Enterprise. On LiveAgent, 15 knowledge bases are Enterprise with 10 included and 5 more at $19 each.
AI on top
What 2,000 AI answers a month add
LiveAgent: no AI fees; your own AI provider charges about $2–3 per 1,000 replies with a low-cost model, so about $4–6. Where the data goes: GDPR.
HelpCrunch: about $464 in packs of 100 AI conversations, from Pro.
Freshdesk: about $980 in packs of 100 sessions, after 500 free sessions once.
HubSpot: $1,000 at $0.50 per resolution.
Help Scout: $1,500 at $0.75 per resolution.
Intercom: $1,980 at $0.99 per Fin outcome.
Zendesk: about $3,000–$4,000 at $1.50–$2 per automated resolution, after 5 per agent included.
The vendors count different things: a resolution or an outcome is charged only when the AI settles the conversation, a session or a conversation every time. Your bill depends on how often the AI can answer, which depends on your articles.
The 11 best knowledge base tools for support teams, one by one
One card per tool: who it suits, where its prices start, how AI is billed, and the catch.
LiveAgent
We make this
Best for small teams that want the knowledge base in the same inbox as every channel
A LiveAgent customer portal (our product).
$11per agent a month on Starter, billed annually; regular $15

SaaS knowledge base examples: 4 help centers to copy
Four software companies whose help centers do one thing especially well, and what to copy from each.
slack.com/help
Slack: an AI search box with the top questions under it
Slack’s help center opens with a single search box, “Ask anything or create a case”, answered by an AI that reads its articles, and three of the most common questions under it, such as resetting a password. The articles and guides sit one click away in the menu. Copy this: put the questions customers ask most right under the search box, and let the AI answer from your articles before anyone writes a ticket.
mailchimp.com/help
Mailchimp: the most-read guides on the front page
Mailchimp puts a search box under its welcome banner and lists its popular guides and tutorials below it, each with a short summary of what it teaches, such as getting started with tags or importing contacts. Copy this: show your most-read articles on the help center’s front page, each with a line that says what the reader will be able to do.
help.dropbox.com
Dropbox: a community next to the articles
Dropbox puts Community right next to Help center in its top menu, and lists popular topics under the search box: reset password, download the desktop app, files not syncing. Copy this: name the three or four problems customers have most often right under your search box, and link your community from every help page.
support.spotify.com
Spotify: topics named after the customer's problem
Spotify Support opens with a search box an AI answers, and under it the help articles grouped by what people come with: payments and billing, managing the account, plans, the app’s features, devices and troubleshooting. Copy this: name your categories after the customer’s problem rather than your product’s menus, and put billing and account first, because those are the ones customers read before they write to you.
In each of them the articles come before the contact form: customers who find the answer don’t need to write, and the ones who still write arrive with the basics already checked.
Only need internal documentation?
If the knowledge base is for your team only, a wiki may be enough. These three are not built for customers: they have no help center, tickets or chat.
Single cards can be shared by link; built for internal answers
A support team usually needs both kinds: an internal page for how to handle a case, and a public article for the customer. A help desk with internal and public articles in one place keeps them next to the tickets they answer.
Want the knowledge base next to your tickets?
LiveAgent puts the knowledge base, emails, chats and contact forms in one place, adds calls and social media messages from Team, and lets AI answer from your articles on your own AI provider, with no AI fees from us. Our team moves your old articles and tickets for free. See how the knowledge base works in LiveAgent.
LiveAgent AI cost estimate: from the AI providers’ list prices in October 2026, for a typical reply in which the AI reads about 20,000 tokens (the conversation, the ticket details and one help article) and writes about 600, with Claude Haiku 5.5 at $0.10 per million input tokens and $0.50 per million output tokens: about $2.30 per 1,000 replies. Prices: Anthropic pricing. Details on AI Answer Assistant.
Changes: November 5, 2026: rebuilt as a comparison of 11 knowledge base tools for support teams, with prices, internal articles, languages and AI billing from each vendor’s pages; the earlier list of 20 knowledge base tools merged into it. October 16, 2023: first published as a list of SaaS knowledge base platforms.
Frequently asked questions
A SaaS knowledge base platform is a cloud tool for writing, organizing and publishing help articles: a public help center customers search, often internal articles for your team, and a search box or widget on your website. You pay a monthly fee instead of hosting it yourself. The ones built into a help desk also let agents use the articles in replies and let AI answer chats and emails from them.
The one that sits where your customers already ask. If they email and chat with you, a help desk with a knowledge base built in (LiveAgent, Zendesk, Freshdesk, Help Scout, Zoho Desk, Intercom) lets agents link an article in a reply and lets AI answer from the same articles. If you only need a documentation site, a standalone tool such as Helpjuice, Document360 or KnowledgeBase does that one job well. For a small team on a budget, Help Scout's free plan or Zoho Desk Standard are the cheapest starts.
For a team of three on annual billing, at regular prices: from free on Help Scout's free plan (one Docs site, 10 articles), then about $36 to $165 a month in a help desk ($270 on HubSpot, which also charges $1,500 once for onboarding), or a flat $49 to $249 a month for a standalone knowledge base. LiveAgent's Starter plan includes one at $45 a month for three agents; the cost chart shows any offer running today. Document360 and Guru quote prices on request.
Yes, with limits. Help Scout's free plan has one Docs site with 10 articles for up to 5 users. Notion's free plan can publish pages as a website, and Confluence is free for up to 10 users but cannot show pages to the public. Zoho Desk's free edition has an internal knowledge base for agents only, and HubSpot's free plan has none. A free plan is fine for a first set of articles; check the article limit before you write more.
Choose a help desk with one built in when the same team answers tickets and writes the articles: agents insert an article into a reply, customers see suggested articles while they write to you, and the AI answers from the same text. Choose a standalone tool when the knowledge base is product documentation that a separate team writes, or when you already have a help desk you keep; then check that the two connect.
Most tools here can, and they bill it in different ways: Zendesk per automated resolution ($1.50–$2 above its allowance), Help Scout $0.75 and HubSpot $0.50 per resolution, Intercom $0.99 per outcome, Freshdesk $49 per 100 sessions, HelpCrunch by packs of AI conversations, Helpjuice from its $449 plan. LiveAgent charges no AI fees: you connect your own OpenAI, Anthropic or FlowHunt account and pay that provider, about $2–3 per 1,000 replies with a low-cost model. The AI is only as good as your articles, so write them first.
An external knowledge base is public: customers find answers themselves, and search engines and AI assistants can read it. An internal one is for your team: refund rules, escalation steps, how to handle a difficult case. Many support teams need both, and several tools put the internal articles on a higher plan (Zendesk on Suite Professional) or need a second, password-protected knowledge base (KnowledgeBase, HelpCrunch).
Two ways: one knowledge base with a translation of each article (Zendesk Suite Professional, Intercom Advanced, Freshdesk Pro, Zoho Desk Professional, HelpCrunch Pro, Helpjuice), or one knowledge base per language (LiveAgent and Help Scout, where each extra one costs more after the plan's allowance). Translate the articles customers open most first, and keep a person who reads the language checking them.
Usually, if you plan it. Export the articles with their categories and images, keep the old URLs in a list so you can redirect them, and check that internal links still work after the move. LiveAgent moves tickets, contacts and knowledge base articles from Zendesk, Freshdesk, Help Scout and others for free on paid plans.
