Open Knowledge Maps is community owned

Dear supporter,

As a charitable non-profit organization, we depend on donations. If every user gave $3, we could run Open Knowledge Maps for a full year.

Open Knowledge Maps is the world's largest visual search engine for scientific knowledge. Our open, ad-free service is used by hundreds of thousands of people. We hope that you'll consider how useful it is to be able to discover scientific knowledge. Not only for a select few, but for everyone on the planet.

Thank you.
Peter, Maxi and Chris from the Open Knowledge Maps board

Free and open discovery for everyone

Open Knowledge Maps is the world’s largest visual search engine for scientific knowledge. We dramatically increase the visibility of research findings for science and society alike.

Turning discovery into a collaborative process

Our vision is to enable collaborative editing of our knowledge maps. Just imagine, how useful it would be to combine artificial intelligence with input from experts in the field.

Open source software for an open science

Don't leave it up to closed systems. Everyone should be able to benefit from scientific knowledge. To reach this goal we need open source non-profit discovery systems for an open science.
