Open Knowledge Maps
Free visual knowledge map of any topic — shows how research clusters relate to each other at a glance.
Overview
Open Knowledge Maps is a non-profit organisation that provides free visual knowledge maps of scientific topics. Based on a search query, it generates a visual map showing how papers cluster by subtopic, allowing researchers to identify the major research threads in any field at a glance. The tool is entirely free and funded by grants and academic institutions.
The maps are generated using an algorithm that groups papers by textual similarity into visual clusters, with representative papers displayed for each cluster. Hovering over papers reveals titles, authors, and publication years. Users can drill down into any cluster for more detail or export the map for inclusion in literature review documents.
Open Knowledge Maps serves as an accessible alternative to more complex research mapping tools, requiring no account and returning results instantly. It is used in secondary and tertiary education to introduce students to a new research field before reading primary literature, and by researchers doing initial scoping reviews. The non-profit model ensures the tool remains free and openly accessible.

Open Knowledge Maps is a free, nonprofit service that turns a literature search into an interactive knowledge map, clustering papers from PubMed and BASE into visual topic groups so you can survey a field quickly. For literature reviews and getting oriented in an unfamiliar research area, the visual overview is genuinely useful and the open, mission-driven model is admirable.
It suits students, researchers and librarians doing early-stage discovery. Caveats: it is more a discovery and orientation aid than a deep analysis tool, the AI/ML element is modest (clustering, not generative), coverage is bounded by its source databases, and it is not a Scopus/Web of Science replacement. Completely free and globally accessible, with an API for the underlying service.
Notable facts
- Open Knowledge Maps generated over 100,000 research maps in its first 3 years with zero marketing budget — entirely through academic word of mouth.
- The platform was built by a former PhD student who was frustrated by the difficulty of finding entry points into unfamiliar research fields.
- Open Knowledge Maps won the European Commission's Open Science Prize in 2017, validating its mission to make science more accessible.
