If your team needs a free knowledge base, start by deciding who must use the information. A person looking up an onboarding procedure needs clear pages and search. An AI assistant answering a support question needs access to current, trustworthy context. Those are related jobs, but a free wiki does not automatically solve both.

For most teams, BookStack is a good starting point for a conventional internal knowledge base, while MkDocs suits teams that already maintain documentation in Git. If the bigger problem is carrying shared context between Claude, Cursor, ChatGPT, and other AI tools, evaluate an AI-accessible memory layer separately. Streamient is built for that job and offers a [hosted Free plan](https://streamient.com/pricing/) with one project and unlimited users. Self-hosting is another option, with its own infrastructure and maintenance costs.

## The best free options depend on how your team works

"Free" can mean free software you run yourself, a hosted product with a limited free plan, or documents kept in tools you already use. The distinction matters: self-hosting avoids a software subscription but still takes time and infrastructure.

| Option                     | Best fit                                                             | What to check before choosing                                                                                  |
| -------------------------- | -------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------- |
| **BookStack**              | Teams that want an organized, browsable internal wiki                | Who will host it, manage access, and keep pages current?                                                       |
| **Wiki.js**                | Teams that want a self-hosted wiki with flexible editing             | Who will administer it, and how will your team organize content?                                               |
| **MkDocs**                 | Technical teams comfortable writing Markdown and publishing from Git | Will nontechnical colleagues be able to contribute?                                                            |
| **Git and Markdown files** | Small teams whose knowledge already lives near code                  | Can people find the right file, and can other tools use its contents?                                          |
| **Streamient**             | Teams that need shared knowledge available across AI tools           | Hosted Free plan: one project and unlimited users. Self-hosting still requires infrastructure and maintenance. |

This is a use-case shortlist, not a claim that every option has been tested against the same feature set. Before committing, verify current licensing, hosting requirements, and any plan limits on the provider's site.

### BookStack: a straightforward place for team documentation

BookStack makes sense when the immediate need is a home for procedures, onboarding material, and reference pages. A team can give information an understandable structure instead of leaving it scattered across chat threads and personal documents.

Its main limitation for an AI-heavy workflow is a question to test, not a reason to rule it out: can the assistants your team uses reliably reach the right page, and will they know when it has changed? If people must copy wiki text into every new AI conversation, the wiki may be doing its job for readers while leaving the context-sharing problem unsolved.

### Wiki.js: a self-hosted wiki for teams willing to administer one

Wiki.js is another option for teams that want control over an internal knowledge base. It is worth considering if self-hosting is acceptable and someone can own setup, access, backups, and maintenance.

Start with a small pilot. Add a decision record, a troubleshooting guide, and an onboarding page. Ask colleagues to find and edit them without help. A free tool is expensive in practice if only its administrator can keep it useful.

### MkDocs or Git files: documentation close to the work

MkDocs is a practical choice when engineers already review Markdown changes in Git. Documentation can follow the same contribution habits as code, which is useful for technical decisions, runbooks, and architecture notes. Plain Markdown files can be enough for an even smaller team.

The trade-off is participation. If support or operations colleagues cannot comfortably propose a change, important knowledge may remain in email or chat. Also, a document being present in a repository does not mean every AI client your team uses can find and apply it. Check the actual path from a source file to an assistant's answer.

## When a knowledge base is not enough

Consider a common handoff: a support teammate investigates a customer issue, an engineer reviews the related code, and someone asks an AI assistant to draft a reply. The relevant context might include an email, a URL, a Git change, and a decision made last month. A wiki page may capture the final procedure, but it may not capture or deliver all of that working context when the next tool needs it.

[Streamient](https://streamient.com/) addresses this narrower problem. It is an open-source, team-owned shared memory layer that brings notes, URLs, emails, Git work, decisions, and project context into an editable, searchable knowledge library. MCP-compatible clients, including Claude, Cursor, ChatGPT, Windsurf, and Zed, can read from and write to that shared context. The aim is to make knowledge available across tools rather than confining it to one person's assistant history.

That does **not** make Streamient a direct replacement for every wiki. If your main task is publishing a stable employee handbook, start with documentation software. If people already have documentation but still re-explain decisions to each AI tool, a shared memory layer may address the missing piece. The [case for shared context across AI tools](https://streamient.com/blog/you-use-3-ai-tools-none-of-them-share-memory/) explains that distinction.

![Five knowledge-base evaluation steps: contribute, find, correct, connect, and maintain.](https://streamient.com/content/images/2026/10/knowledge-base-evaluation.webp)

Evaluate the full workflow: contributing knowledge, finding it, correcting it, connecting tools, and maintaining the system.

## A five-question test before you choose

Run the same small trial with each option you are considering. Use real, non-sensitive examples from your work rather than a polished demo document.

1. **Can everyone who knows something add or correct it?** Give a support colleague and an engineer the same editing task. If one cannot complete it, decide who will maintain their contributions.
2. **Can someone find the answer without knowing its title?** Search for a customer issue, a project decision, or a procedure using the words a new teammate would use.
3. **Can you inspect and fix a wrong answer?** Locate the underlying source and update it. Search quality matters, but so does the ability to correct what people and AI tools may rely on. Streamient's [search and bulk organization update](https://streamient.com/blog/exact-tag-search-bulk-actions/) shows the kind of maintenance work to consider.
4. **Can your AI tools use the knowledge where work happens?** Test a question in the clients your team uses. Do not assume that exporting pages or connecting one assistant gives every tool the same context.
5. **What does "free" cost your team?** Record hosting, administration, backups, permissions, and migration work. For hosted services, check current free-plan limits before building a workflow around them.

A useful trial has a clear pass condition. For example: "A teammate can update a decision, and another teammate can find the corrected answer in their usual tool without asking where the document lives." If a conventional wiki passes, you may not need anything else. If it fails specifically at the AI handoff, test a shared memory approach.

## Is Streamient a free knowledge base tool?

Yes. Streamient offers a hosted Free plan with one project and unlimited users. It includes notes, memories, URLs, stored emails, a knowledge graph, semantic search, and MCP tools. Review the [current pricing and plan limits](https://streamient.com/pricing/) before choosing a deployment. Streamient was formerly called Kumbukum; the [founder’s story](https://streamient.com/about/) explains the rename. The software can also be self-hosted, which still requires infrastructure, backups, and maintenance.

The more important fit question is whether you want a conventional knowledge base or shared context for AI work. Streamient is designed around the latter: team-owned knowledge that people can inspect and edit and that compatible AI clients can use across workflows. Its [approach to knowledge capture](https://streamient.com/blog/simplifying-knowledge-capture-why-complex-wikis-are-failing-teams/) is relevant if your team's information rarely starts life as a finished wiki page.

## Frequently asked questions

### What is the best free knowledge base for a small team?

For a small team that wants pages people can browse and update, start by trialing BookStack or Wiki.js. If the team already works in Markdown and Git, try MkDocs or a simple repository first. The best choice is the one your colleagues will maintain and can search successfully, not the one with the longest feature list.

### Can free knowledge base software give AI assistants shared memory?

Not necessarily. A knowledge base stores information; shared AI memory also requires a usable way for assistants to retrieve and, where appropriate, update team context. Test that workflow in each AI client you use. If staff still have to paste the same background into new conversations, your documentation may be sound, but your AI tools are not sharing it.
