Knowledge Management

Your company already knows the answer. Now everyone can find it.

Castia Knowledge connects every document, wiki, drive, and system you have into one assistant that answers in plain language and shows you exactly where the answer came from.

The challenge

What this looks like today

The policy exists. It's in a PDF, in a SharePoint folder, that three people know about.

People ask a colleague instead of searching, because searching never works.

Half your wiki is out of date and nobody knows which half.

Every new starter re-asks the same forty questions.

The product

Everything you'd expect from Castia Knowledge

The features you'd want from any tool in this category — because this is a product, not a plugin.

Unified search

One search box across Drive, SharePoint, Confluence, Notion, email, and your databases.

Knowledge base & wiki

Author, version, and own internal documentation — with a clear owner and review date on every page.

Permission-aware access

People see only what they're already allowed to see. Search never becomes a data leak.

Connectors to everything

Files, drives, wikis, ticketing, CRM, databases — connected, indexed, and kept in sync.

Content health

See what's stale, what's duplicated, and what nobody has opened in a year.

…and everything you can’t get anywhere else

Castia Knowledge is built on the Castia platform — so enterprise search, knowledge AI, reporting, workflow automation, and agents all apply directly to your work.

Ask, don't search

"What's our parental leave policy in Ireland?" — a plain-language answer with the paragraph and the document it came from.

Semantic retrieval

Finds the right document even when it doesn't contain a single word you typed.

Document intelligence

Summarise a 90-page contract, extract every obligation, compare two versions of a policy.

An onboarding assistant

New starters ask the assistant instead of interrupting the team — and get a sourced answer every time.

Answers with citations

Every response links to the source. If Castia can't find it, it says so instead of inventing it.

In practice

From question to finished work

Ask in plain language. Castia does the reading, the reconciling, and the drafting.

You ask

What's our data retention policy for EU customer records?

Searches every connected sourceFinds the governing policyChecks it's currentCites the clause

Castia delivers

The answer in two sentences, the exact clause quoted, a link to the policy document, its last review date, and a note that a conflicting older version still exists in SharePoint.

Outcomes

What changes

One place to ask, instead of five places to search

Answers cited to the source — trustable, not plausible

New starters self-serve from week one

Stale and contradictory documents surfaced automatically

Institutional knowledge survives people leaving

Connectors

Open source. Free to start. Pay only for what the AI does.

Knowledge tools that charge per seat are self-defeating — the whole point is that everyone can find the answer. Castia charges for usage, so the entire company gets access on day one.
