An AI knowledge management tool, also called an internal wiki, company knowledge base or company brain, is a knowledge base that lets staff and AI find answers in a company's own documents, instead of asking the same person the same question twice. Slite scores highest in this test at 40 out of 50, ahead of Guru (36) and Notion (35).
Hourglass, which publishes this guide, sells its own company brain build, so it is described below and not scored.
This guide is for the owner or ops lead at an Australian business with 5 to 200 staff who wants a single source of truth that can answer repetitive questions in plain English. Every product below was scored on the same 50 points, using only what each vendor publishes. Pages were read on 5 October 2026.
The short answer
- Best value: Slite (40/50). AI answers, page verification and a published price of US$10 a user a month. It loses on data region, as all production data sits in the EU.
- Best answers: Guru (36/50). The only full marks on answers and on connections. It loses on price, because no price is published on the pages read.
- Best for data controls: Notion (35/50). The best data score in the test. It loses on price, because the AI needs the US$20 Business plan.
- Best for Sydney hosting: Confluence (26/50). The only product whose pages read show an Australian hosting region, and the cheapest AI plan at US$5.42. It loses on upkeep and data statements.
The best AI knowledge management tools, ranked
Slite ranks first of six at 40 out of 50, then Guru at 36, Notion at 35, Tettra at 28, Confluence at 26 and Glean at 17.

1. Slite
- Best for
- Value for money
Slite is a knowledge base for small teams that answers questions from your docs with AI. It took full marks on upkeep, with a page verification workflow and an audit log, so stale pages get flagged before staff trust them. It also took full marks on price. The Basic plan is US$10 a user a month on yearly billing, with AI answers included, and the Slite pricing page publishes it in full. Its security page states that customer data is not used to train models, and it met the certification test. The Slite pricing page names AI answers inside Slack or Microsoft Teams, which earned 3 of its 7 answers points. No citations on answers were found on the pages read, which cost the other 3.
Ferndesk, a help-centre vendor that reviews this category, puts it this way: "Slite built its reputation on clean design, then added genuinely useful AI."
Loses on: data region. All production data is hosted in the EU (St. Ghislain, Belgium), with no region choice. That cost 4 of the 10 data points.

Need answers from your inboxes, CRM and accounting data too?
A knowledge base answers from the documents you put into it. If the answers your team needs also live in inboxes, the CRM or the accounting system, Hourglass can build a company brain that reads those too, on your own server. Book a 30-minute call and Hourglass will map what it would connect to.
2. Guru
- Best for
- AI answers and connections
Guru is the only product in this test with full marks on answers. Its AI answers come from your docs, show citations and respect each user's permissions, and they work inside Microsoft Teams as well as Slack. It also took full marks on connections. The Guru integrations page lists Google Drive, SharePoint and an MCP server, so other AI tools can read the same knowledge. Upkeep also scored 10, with a verification workflow and an audit log. Its security page earned 6 data points: 3 for a statement that customer data is not used to train models and 3 for certification. No region choice and no Australian hosting region appear on the pages read, which cost the other 4.
Loses on: price. No price is published on the pages read. It scored 0 on the price test. Without that test, Guru would rank first at 36.
3. Notion
- Best for
- Data controls
Notion has the best data score in this test. Its security page states that customer data is not used to train models unless the customer opts in, and it lists SOC 2 and ISO 27001. Its data residency help page offers a choice of region. Upkeep scored 10. The answers points rest on Enterprise Search, which sits on the Business plan and is marked Beta on the Notion AI page.
Ferndesk calls it the default pick for an internal wiki: "For an internal wiki, Notion is the safe default and Slab is the best free option for teams of up to 10 people."
Loses on: price. The Plus plan at US$10 a user a month includes only a "Trial of Notion AI". The AI needs the Business plan at US$20, above the US$10 line in this test. The residency table also has no Australian region. US, EU, Tokyo, Osaka and Seoul were listed.
4. Tettra
- Best for
- Slack teams
Tettra is built for teams that live in Slack. Its AI answers come from your docs, and it has a page verification workflow. The Tettra pricing page lists US$8 a user a month with AI, which earned full marks on price. There is a 10-user minimum, so the smallest bill is for 10 seats.
Ferndesk sums up the design choice: "Tettra made a bet: teams that live in Slack want their knowledge base in Slack too."
Loses on: data. The Tettra security page returned a 404 when read, so there is no published statement on model training, certification or hosting region. It scored 0 of 10 on data.
5. Confluence
- Best for
- Australian (Sydney) hosting
Confluence is the only product in this test whose pages read show an Australian hosting region. The Atlassian data residency page states: "Australia Consists of Australia (Sydney) region". Data residency is available on the Standard, Premium and Enterprise plans. It also has the cheapest AI plan in this test. Standard is US$5.42 a user a month with Rovo, Atlassian's AI, on the Confluence pricing page. Confluence has an audit log.
Ferndesk notes: "Confluence is the default if you're already using Jira."
Loses on: upkeep. No page verification workflow appears on the pages read, so it scored 4 of 10.
Loses on: data. No statement on model training and no SOC 2 or ISO 27001 statement appears on the pages read. It scored 4 of 10, all from hosting region.
6. Glean
- Best for
- Enterprise search across connected apps
Glean is enterprise search rather than a wiki. It lists 250+ connectors and took full marks on connections. Its security page lists SOC 2 and ISO 27001. AI answers come from your docs.
Loses on: price. The Glean pricing page offers a demo only, with no published price. It scored 0 on price.
Loses on: upkeep. No verification workflow or audit log appears on the pages read.
Loses on: data. No training statement and no region choice appear on the pages read. It scored 3 of 10, from certification only.

Why the knowledge base comes before AI agents
Hourglass, which sells a company brain, argues that the knowledge base has to come first. Many teams buy AI agents or pick an agent framework first and find the agents cannot answer anything specific to the business. Michael Batko, founder of Hourglass, described the pattern in a podcast interview: "most companies start at agents and they built themselves a bunch of agents they all break ... because the foundation and infrastructure isn't in place".
In the same interview he contrasted a plain AI chat, which gives "almost a generic kind of web scrape", with one connected to a company brain, which gives "the specifics of last engagements, emails and PDFs". That gap is what the answers and connections tests in this guide measure.
Another option: a company AI brain on your own server
Hourglass, the publisher of this guide, builds a Company AI Brain. It is not scored or ranked here. Its product page describes it as "plain text files in a graph, on your server, pointed at any model", running on the customer's own servers and accounts. The page says it is "connected to any model via MCP" and that "every week it consolidates loose notes into clean, canonical pages". It is positioned as "a knowledge layer that sits above your systems of record, not a replacement for them", so it can sit alongside any tool above. No price is published on that page.
How this guide was tested
- Answers, 10 points. AI answers from your docs (4), citations or a verified badge on answers (3), answers inside Slack or Microsoft Teams (3).
- Upkeep, 10 points. Page verification or expiry workflow (6), audit log (4).
- Connections, 10 points. Google Drive (3), SharePoint or Microsoft Teams (3), search across connected apps (2), API or MCP (2).
- Data, 10 points. Data not used to train models (3), SOC 2 or ISO 27001 (3), choice of data region (2), an Australian hosting region (2).
- Price, 10 points. A published per-user price (5), a plan with AI answers at US$10 a user a month or less (5).
Total score out of 50. Scored 5 October 2026.
The reviewers chose one buyer and one use: an internal company knowledge base for an Australian small or mid-size business. Search results for this topic mix four kinds of product, and only internal wikis and company knowledge bases were scored.
The rubric has 50 points across five tests. Weights were fixed before scoring.
Every point rests on a quote saved from the vendor's own page on 5 October 2026. A build script checks that each quote appears word for word in its saved page. A feature that was not found on the pages read scored 0, even if it may exist elsewhere. Three claims were rejected. Notion Plus was not counted as an AI plan because it includes only a trial. Slite was not given region choice because its data is EU only. Confluence was not given answers in Slack, because the only evidence was a customer testimonial about adoption, not a feature.
Not scored, and why:
- Document360, Zendesk and Ferndesk: customer-facing help centres, not internal knowledge bases.
- Microsoft 365 Copilot, Gemini and NotebookLM: assistants bundled with an office suite.
- Obsidian, Mem and Reflect: personal second brain apps, not team tools.
- Hourglass Company AI Brain: the publisher's own product.

Common questions
What is the best AI knowledge management tool for a small team?
Slite is the best AI knowledge management tool in this test, with 40 out of 50. It combines AI answers, page verification and a published price of US$10 a user a month. Guru (36) has stronger answers and connections but publishes no price. Notion (35) has the best data controls.
Which knowledge base answers questions inside Slack or Microsoft Teams?
Guru, Slite and Tettra answer inside Slack or Microsoft Teams, according to their own pages. Guru also shows citations on its answers and took full marks on the answers test.
Which knowledge management tool hosts data in Australia?
Confluence is the only product in this test whose pages read show an Australian hosting region, in Sydney, on its Standard, Premium and Enterprise plans. Notion offers region choice but listed no Australian region. Slite hosts all production data in the EU.
What is the cheapest AI knowledge base?
Confluence Standard at US$5.42 a user a month with Rovo is the cheapest published AI plan. Tettra is US$8 a user a month with a 10-user minimum. Slite Basic is US$10 a user a month on yearly billing.
Does Notion AI come with the Plus plan?
No. The Notion Plus plan at US$10 a user a month includes only a trial of Notion AI. The full AI needs the Business plan at US$20 a user a month.
Is an internal wiki the same as a company AI brain or a second brain?
Not quite. An internal wiki holds pages that staff write and maintain. A company AI brain also draws on inboxes, files and business systems so AI can answer from all of them. A second brain usually means a personal note app such as Obsidian, Mem or Reflect, which were not scored here.
