Open Knowledge Maps: cost, fit and limits
Open Knowledge Maps is a nonprofit service run by a registered association in Austria that turns research searches into visual maps, grouping related outputs into labeled areas with an AI-based clustering pipeline. It targets readers who want orientation before detail.
What to know first
Open Knowledge Maps publishes no prices or subscription tiers: its about page asks for donations and supporting memberships and mentions custom services for institutions without cost details. The page does not say outright whether use is free. It claims coverage of more than 400 million research outputs across more than 25 output types and emphasizes open access. The page does not describe chat, extraction or screening features.

Who Open Knowledge Maps is best for
Newcomers to a research field
Results are grouped into areas labeled with concepts, so a beginner sees the main subtopics before reading individual papers. Beginners avoid reading a long list.
Open access advocates
The service highlights open access resources in its results, which suits readers who want papers they can open without a subscription.
Institutions wanting an embedded map
The about page lists custom services for embedding the tools in an institution's own site, though no cost details are published.
Supporters of nonprofit infrastructure
Support is by donation or supporting membership, run by a registered association, which fits groups that prefer community-run tools. The association form makes its legal status clear.

What Open Knowledge Maps does
- Visual overviews
- Related resources are grouped into areas labeled with concepts, so the result is a map of the field instead of a flat ranked list. Maps work as an orientation step.
- AI clustering pipeline
- An AI pipeline clusters similar resources and labels the research areas. The page describes an AI-generated query summary only as a future concept. Labels come from concepts found in the results.
- Open access emphasis
- Open access resources are highlighted in the results, which helps a reader find full texts without paywalls. Readers can then move straight to freely available full texts.
- Broad coverage claim
- The page claims more than 400 million research outputs across more than 25 output types, a figure that is the vendor's own and was not checked.
- Custom services
- Institutions can embed the services in their own environment, with details and costs available on request according to the about page. Pricing is available only by contacting the association.
How Open Knowledge Maps handles your data
The privacy policy linked from the about page says access logs are deleted after 30 days for regular access, error logs after 90 days and security logs after 180 days. It names US-based processors, Google Drive, MailChimp and PayPal, so the vendor's policy was not checked for a single hosting region. Whether searches or content are used to train models is not stated, and the privacy page itself returned an error when fetched. No certifications are held according to the policy.
Where Open Knowledge Maps falls short in practice
- Free use not stated. The about page lists no prices and does not say whether use is free, so budgeting depends on contacting the association. A university buyer needs a written answer.
- No assistant features. No chat, extraction table or screening feature is described, so it works as an orientation aid and not as a review workflow. Reviewers should pair it with an assistant or extraction tool.
- Unchecked coverage claims. Coverage figures are the vendor's own claims and could not be checked against the pages opened. Test a topic you know before trusting the maps for coverage.
- Processors in the United States. The policy names US-based processors, which can matter to European institutions even though the association is Austrian. Check data processing terms with the association if that matters to you.

Open Knowledge Maps: common questions
Is Open Knowledge Maps free?
The about page lists no prices or subscription tiers and asks for donations and supporting membership, but it does not say outright that use is free. Contact the association if you need a firm answer for an institution. Ask for confirmation in writing.
Who runs Open Knowledge Maps?
The privacy policy describes a registered association, Open Knowledge Maps, Verein zur Förderung der Sichtbarkeit wissenschaftlichen Wissens, and the country is Austria. It offers custom services for institutions without published cost details. That detail helps when an institution fills in a procurement form.
How much does Open Knowledge Maps cover?
The about page claims more than 400 million research outputs across more than 25 output types. This is the vendor's own figure and we could not check it, so test the tool with a topic where you know the literature.
Does Open Knowledge Maps use AI?
Yes in a limited way: the about page names an AI-based visual interface and a pipeline that clusters similar resources and labels research areas. An AI-generated query summary is described there only as a future concept. The clustering itself is not described in detail.
What does Open Knowledge Maps do with my data?
Access logs are deleted after 30 days, error logs after 90 and security logs after 180, per the privacy policy. It names US-based processors such as Google Drive, MailChimp and PayPal, and does not state a training policy. Ask the association for an up-to-date policy.
