In their own words
Stack Internal
Stack Internal is a cloud knowledge product that delivers verified information to people, teams, and AI agents. It captures and synthesizes material from AI tools, chat threads, and wikis into knowledge units carrying authorship, recency, usage, provenance, and conflict signals. Teams arrange content in spaces and assign permissions to people, teams, and agents. Listed connectors cover Google Docs, Slack, Microsoft Teams, and Stack Internal Community, with an ingestion API for other tools. An MCP server connects AI assistants and coding agents, including Claude and Cursor, to the stored knowledge. AI search or answers and single sign-on are supported. The Free plan costs nothing for up to 50 teammates. Starter is also free, with up to three collaborators, 1,000 credits monthly, four connectors, a custom ingestion API, and unlimited ingestion. Organization pricing is based on required Knowledge Flow Credits and requires contacting sales. Security listings include ISO 27001/27701, SOC 2 Type II, SCIM, GDPR and SCC.
XWiki
XWiki is an open-source enterprise wiki and knowledge-management platform for collaboration, document management and structured data. It can be used for knowledge bases, collaborative intranets, public websites and business applications, with publishing for internal or external audiences. Editors can work in wiki syntax or a WYSIWYG interface, while version control allows earlier pages to be compared or restored. Page rights can govern viewing, editing and deletion at the page, child-page or whole-wiki level. More than 900 extensions include applications, macros, skins, plugins and themes. Listed connectors include Active Directory, Office 365, Google Apps and OnlyOffice; a RESTful API supports integration with other applications. XWiki is available as a self-hosted installation or through XWiki Cloud. Its Community edition is self-hosted and open source; cloud plans list capacities from 25 users to unlimited users. XWiki Cloud's 10-day demo trial can be extended twice. Cloud service is hosted in France on OVHcloud and includes backups, monitoring, antivirus scanning and security maintenance. If storage exceeds a plan allowance, wiki actions may be limited to viewing pages.
