Our verdict on ZAQ

ZAQ is an open-source AI knowledge base for organizations that want people and AI agents to query company information across documents, chats, and email. It is aimed at technical teams that need to keep answers tied to source material and permissions, with the option to run the application on customer infrastructure, including on-premise deployments. Its continuously updated knowledge base and administrative controls make it a specialized choice for teams prepared to manage a self-hosted system.

The central workflow combines source scanning with natural-language answers, citations, and links to the underlying material. ZAQ applies access-aware retrieval based on user permissions, and processes documents including PDF-to-markdown conversion. An administrative panel covers ontology, documents, and system configuration. Organizations can configure a language-model endpoint they provide, which gives them control over that connection but also makes model setup part of the deployment. The listed integrations are Mattermost and email through IMAP/SMTP; Slack is described as planned. Teams whose knowledge workflow depends on a broader set of ready-made connectors should consider alternatives.

ZAQ is open source and has a free plan. Its GitHub project materials describe AGPLv3 use and say a commercial license is available for organizations needing different terms. There are no published paid tiers to compare here, so the key buying consideration is licensing and the operational work of customer-hosted deployment rather than a plan ladder. Support channels include community resources and documentation. Choose ZAQ if your technical team values on-prem deployment, permission-aware answers, and source citations enough to own the setup; look elsewhere if you need a larger listed integration ecosystem or a managed service with clearly tiered commercial plans.
