Omniago is described as 'OmniDebate is a platform for climate activists to debate and crowdsource information and sources. You create, vote, and revise posts with your team members. Only the top voted posts are made public on the topic page' and is an website in the Education & Reference category. There are four alternatives to Omniago, not only websites but also apps for Android and iPhone. The best alternative is Kialo, which is free. Other great sites and apps similar to Omniago are Socratrees (Free), Ceasefire (Free) and DebateIsland (Free).
Socratrees outlines arguments into intuitive hierarchies of supporting and opposing statements. This design is loosely based on argumentation theory. However, we do not expect you to be familiar with theory in order to start using Socratrees.
Previously, ChangeAView.com, now rebranded as Ceasefire, the website is based on the principles founded by the reddit community /r/ChangeMyView, and it aims to encourage insult-free discussions, and exploration of opposite points of view.
DebateIsland.com is a leading online debate platform which uses A.I. to revolutionize online debating. The site features numerous debating formats including Casual, "Persuade Me," Formalish, Formal Traditional Debating, and Lincoln-Douglas Debating.
