About Cohere

The Web is about IDEAS+PEOPLE.

Cohere is a visual tool to create, connect and share Ideas.

Back them up with websites. Support or challenge them. Embed them to spread virally.
Discover who - literally - connects with your thinking.

Publish ideas and optionally add relevant websites

Weave webs of meaningful connections between ideas: your own and the world's

Discover new ideas and people

We experience the information ocean as streams of media fragments, flowing past us in every modality.

To make sense of these, learners, researchers and analysts must organise them into coherent patterns.

Cohere is an idea management tool for you to annotate URLs with ideas, and weave meaningful connections between ideas for personal, team or social use.

Key Features

  • Annotate a URL with any number of Ideas, or vice-versa.
  • Visualize your network as it grows
  • Make connections between your Ideas, or Ideas that anyone else has made public or shared with you via a common Group
  • Use Groups to organise your Ideas and Connections by project, and to manage access-rights
  • Import your data as RSS feeds (eg. bookmarks or blog posts), to convert them to Ideas, ready for connecting
  • Use the RESTful API services to query, edit and mashup data from other tools
