## Open Knowledge Maps

Open Knowledge Maps, often shortened to OKMaps, is an open-science platform whose mission is to dramatically increase the visibility of research findings. Rather than returning a ranked list of links, it builds an interactive knowledge map from your search terms: related items are grouped into bubbles and color-coded clusters, so you can immediately see which subtopics exist and which of them matter most to your question. Clicking a cluster expands it, and each node links out to the underlying metadata and source record.

The service queries BASE, one of the world's largest open repositories aggregators, covering more than 400 million outputs from over 11,000 sources, including publications, datasets, software, and images. Because the visual layout is generated directly from the metadata rather than from generated text, the project emphasizes that results contain no hallucinations. Everything is delivered in a browser, requires no installation and no account, and the underlying software is open source on GitHub.

Open Knowledge Maps is operated as a charitable non-profit organization. It is free for anyone to use and sustains itself through supporting members such as university libraries, plus grants and donations. It also offers custom services so institutions can embed its discovery components into their own search portals. The result is infrastructure aimed at students, researchers, librarians, and curious non-specialists who want a faster, more intuitive entry point into a field.

**Pricing & Plans:** Free for all users. Open Knowledge Maps is a charitable non-profit funded by supporting members (libraries and institutions), grants, and donations, with optional paid custom-integration services for organizations.

- **Visual knowledge maps:** Every search produces an interactive concept map in which related research outputs are grouped into labeled, clickable clusters instead of a single flat list.
- **400M+ research outputs:** Searches more than 400 million records in over 400 languages pulled from more than 11,000 sources through the BASE aggregator.
- **25 output types:** Beyond journal articles, results span datasets, software, images, and other research objects, giving a broader picture of a topic.
- **No AI hallucination:** Maps are generated from metadata rather than synthesized text, so what you see corresponds to real indexed records.
- **Open source and embeddable:** The platform is open source on GitHub, and institutions can integrate its discovery components into their own systems via custom services.

**Strengths:** Completely free with no account or installation required; Visual clustering makes the structure of a topic obvious at a glance; Nonprofit, open-science mission with an open source codebase; Metadata-driven results avoid the hallucination risk of text-generating search tools

**Limitations:** Coverage is limited to what is available through the BASE aggregator; Map quality depends on how specific your search terms are; No built-in full-text reading, saving, or personal library features

## Structurepedia

Structurepedia approaches knowledge visually. Rather than returning a single article or a long list of links, it organises a subject into an interactive tree: the main topic sits at the centre, related areas branch out from it, and each branch can be expanded into finer detail. The result is a map you can navigate, which makes it easy to see how the parts of a field fit together before you commit to reading anything in depth.

The tool is aimed at anyone who needs orientation in a subject quickly. A student can preview a module, a teacher can project the structure in class, and a researcher can sweep a discipline to spot the areas they have not yet considered. Because the nodes link onward to fuller explanations and resources, the tree works as a starting point for study rather than an endpoint.

Structurepedia belongs to the same family of ideas as mind mapping tools and knowledge bases, but it leans into diagram-like navigation and visual search. It is a free web tool, so exploring a tree needs nothing more than a browser. Note that availability of our listing's source page could not be confirmed during this audit, so treat the site as operational but check it directly before relying on it in a workflow.

**Pricing & Plans:** Free to use in the browser. No paid tier or subscription is advertised.

- **Interactive knowledge trees:** Every topic is presented as an expandable tree so you can see the whole field at once and zoom into the branch you need.
- **Visual learning layout:** Colour, hierarchy and connecting lines do the explaining, which helps when a written article would be too linear or too long.
- **Depth on demand:** Nodes on a tree lead to deeper material on the same subject, so an overview quickly becomes real research.
- **Topic search:** Ask the search interface for a subject and get a structured map back instead of a list of unrelated links.
- **Education-ready:** Works for school lessons, university reading and self-study, and gives teachers a ready visual aid for a lesson or lecture.

**Strengths:** Visual tree structure makes complex subjects easier to grasp at a glance; Useful for lesson planning, revision and self-directed study; Free to use in a browser with nothing to install; Links out to deeper resources when you need more detail

**Limitations:** Coverage is broad but not exhaustive, so niche or very recent topics may be thin; Diagram depth varies by topic depending on how much community content exists; No account sync or study-tracking features are described
