Plans and prices

unkwn42 is a search engine for climate and earth science literature. Give it a research idea or an abstract and it finds the closest prior work, including work described in other words or in other fields, and says how yours differs. Every plan is access to the same platform; paid plans remove the monthly limit.

Founding memberships are open. 50 places for early users: a price that never goes up while you stay, a direct line to the founder, and a say in what we build next. To ask for one, write to hello@unkwn42.com.
