What SlimWiki is
SlimWiki is a collaborative wiki for teams and individuals who need to create, organize, and share knowledge. Users can manage multiple wikis, teams, and organizations, with search and discovery tools for finding pages. Wikis may be public or private and shared with collaborators, whose changes can appear as they happen. Pages support images and attachments, with storage management, version history, custom branding, and custom domain names. SlimWiki includes single sign-on, including Google SSO for helping organization members join wikis. Its Slack app can search wiki pages, connect multiple wikis, and create pages from Slack. The service is positioned for sales processes, marketing playbooks, product documentation, communities, and clubs. It is available through the web and an API. SlimWiki offers a Free plan at no cost for up to three users. Academic and Enterprise plans use custom quotes. The maker is headquartered in Singapore and was founded in 2013.
