Can an intranet replace a knowledge base?

Up to a few hundred documents, usually. The limit shows up in search and in ownership: when nobody can tell whether a page is still valid, you have an archive rather than a knowledge base, and that is worse than nothing.

Do we need all three?

Below about 200 people, rarely. Above that it depends less on headcount than on compliance: a regulated company almost always ends up with a separate LMS, because producing evidence on demand is a job the other two are not built for.

What is the most common mistake?

Buying by feature list. All three list search, documents, notifications and analytics, so the lists look interchangeable. The distinction is in what each tool makes happen: assignment, findability, or attention.

Where does TeamEvo sit?

It is an intranet with learning and a knowledge base inside it. That means one entry point and one login, at the cost of depth in each individual area — there are no packaged course standards, no proctoring and no compliance archive. Our own LMS page lists those gaps.

Comparison

LMS, knowledge base or intranet

All three hold company information, all three claim the others' features on their pricing page, and buying the wrong one costs a year. The difference is not in the feature lists — it is in what each one is built to make happen. This page is the distinction, with the overlaps named honestly.

What each one is actually for

LMS

To make sure a specific person has learned a specific thing, and to be able to prove it later.

Does best: Assignment and proof. Someone is given a course, progress is tracked, understanding is checked, completion is recorded with a date and a certificate.
Asked to do, and shouldn't: Used as a document library. Material that changes weekly does not belong in a format built around versions, assignment and completion.
Examples: Moodle, Docebo, TalentLMS, iSpring Learn, 360Learning

Knowledge base

To hold the current answer to a question someone will ask again next month.

Does best: Findability and currency. Structure, search, ownership of each page, and a visible signal of whether a document is still valid.
Asked to do, and shouldn't: Used to train new hires. A well-organised wiki assumes the reader already knows what to look for — which is exactly what a new hire does not.
Examples: Confluence, Notion, Guru, Document360

Intranet

To be the place people open every day, where the rest of the company is reachable.

Does best: Attention and context. News, people, teams, tasks and events in one place, so information reaches people who were not looking for it.
Asked to do, and shouldn't: Used as a document archive. A feed is a terrible filing cabinet: the important post is three months down the scroll.
Examples: SharePoint, Simpplr, Staffbase, Happeo

The criteria that separate them

No scores in this table on purpose: every cell is a statement about what the tool is built to do. "Not designed for this" is a fact about purpose, not a complaint about quality.

Criterion	LMS	Knowledge base	Intranet
Core unit	A course, assigned to a person	A page, owned by someone	A post, a profile, a task
How people arrive	They are assigned it, with a deadline	They search for it when a question comes up	They open it out of habit, or a notification brings them
What proves it worked	Completion, a passed check, a certificate with an expiry date	The answer is found, and it is current	People come back tomorrow
Handles frequent change	Poorly. Republishing a course for a small edit is heavy by design	Well. Editing a page is the normal operation	Well for announcements, poorly for reference material
Handles compliance evidence	Built for it: who completed what, when, and when it expires	Not designed for this. Page views are not proof of understanding	Not designed for this
Works for a new hire in week one	Yes, if someone built the path	Only if they already know the vocabulary	Yes for orientation, no for structured learning
Main failure mode	Courses nobody finishes, because nothing reminds them and it lives in a separate login	Documents that are quietly out of date, which is worse than having none	A feed that becomes noise, so the important announcement is missed
Who usually owns it	L&D or HR	Whoever wrote the first page, then nobody	Internal communications or HR

Where they genuinely overlap — and what to do about it

Every intranet ships a document section, and it is usually good enough for a hundred pages and clearly not good enough for a thousand. The honest test is not the feature list but the search: type a phrase from the middle of a document and see whether it comes back.
Most knowledge bases can assign a page as required reading. That covers policy acknowledgement; it does not cover teaching, because reading is not the same as understanding and a view is not a check.
Several LMSs include a resource library. It works for stable reference material attached to a course, and it goes stale for anything that changes weekly — the workflow around it assumes publishing, not editing.
The overlap is real enough that a company under about 200 people usually needs one tool rather than three. The question is which single problem is most expensive right now: nobody finds the regulation, nobody finishes the training, or nobody reads the announcement.
Above roughly 500 people, or under a compliance regime, the LMS usually separates out first — because evidence has to be produced on demand, and that is the one job the other two are not built for.

Which one first, depending on the problem

"People keep asking questions that are already answered somewhere": Knowledge base. The problem is findability and ownership, not training. Buying an LMS for this produces courses about where the documents are.
"We have to prove people were trained": LMS, and check the evidence export before anything else. Assignment, completion, expiry and re-certification are the whole product here; a knowledge base cannot substitute for them.
"Nobody knows what is going on in the company": Intranet. This is an attention problem: the information exists, it just never reaches anyone who was not looking for it.
"New hires take three months to become useful": This is usually all three at once, which is why onboarding is the scenario that exposes a fragmented setup fastest. Start with the structured path — an LMS or a portal with learning attached — and connect the documents to it rather than the other way round.
"We have all three and people still use none of them": The problem is entry point, not features. Three logins mean three habits, and people sustain about one. Consolidating onto whichever tool people already open daily usually beats buying a fourth.
"We are 100–500 people and want one tool": This is where we fit: TeamEvo is a portal with learning and a knowledge base inside it, which trades depth for a single entry point. If you need packaged course standards, proctoring or a compliance archive, take a dedicated LMS instead — we say so on our own LMS page.

Frequently asked questions

For policy acknowledgement, often yes. For anything that has to be understood rather than read, no: the missing pieces are the check, the record and the expiry date. If you never have to prove training happened, the knowledge base may be enough.
