river42 is a set of small tools with an “open Web” orientation. Its current flagship product is Guide, an AI workspace for teams. It lets users chat with frontier models or open-weight models while constraining answers to the context of the team’s own knowledge bases, code repositories, policies, and documents. The product is based on Open WebUI and emphasizes EU hosting, per-customer isolation, and controllable knowledge bases.
Typical Guide use cases include Q&A over engineering codebases, document retrieval for professional services, and compliance-material lookup for regulated enterprises. For engineering teams, it can sync manuals and service repositories, using full-text search, code graphs, and signals such as git log, blame, and pickaxe to answer questions like “who changed what, and why.” For contract and policy libraries, it supports document-tree mirroring, OCR for scanned PDFs, BM25 retrieval, and citations to source documents and clauses in its answers. For companies that cannot send materials outside their environment, the knowledge-base runtime can remain on the customer’s internal network, with Guide accessing it through a private tunnel.
The main content does not disclose plans, pricing, a free tier, or a trial. Deployment appears to be more enterprise-sales oriented: users need to describe the form of their knowledge base, after which river42/sysinit sets up the tenant. The workspace runs on EU infrastructure; the knowledge base can be hosted by river42 or deployed on the customer’s own hardware.
Security design is the product’s most distinctive aspect: each customer gets a tenant group, with an independent knowledge-base backend and access authorization, no shared indexes, and no cross-tenant retrieval. It supports customer OIDC SSO, disables self-service sign-up, and keeps membership explicit and auditable. On the data side, it emphasizes that data does not pass through a US control plane, and that the knowledge base is “read by the model but not retained.” However, the page does not provide formal compliance materials such as SOC 2, ISO 27001, or a DPA. For integrations, it explicitly mentions only code repositories, document trees, OIDC, and private tunnel/TLS endpoints; specific connectors such as GitHub, SharePoint, and Google Drive are not listed.
Its strengths are a clear data-sovereignty story, granular tenant isolation, support for local knowledge bases, and the ability to handle real enterprise materials such as code, contracts, and scanned documents. Its weaknesses are opaque commercial information, with no pricing, SLA, support channels, or self-service trial, while ecosystem integrations and API capabilities are also not fully disclosed. It is better suited to European engineering teams, consulting firms, and compliance/IT departments—or anyone that cares strongly about data location. It is less suitable for individuals or small teams that just want a low-cost, self-service setup.
Access status from mainland China is unknown. The main content also does not mention RMB payments, invoicing, local nodes, or Chinese-language support. Companies looking to deploy similar capabilities in China can compare Dify, FastGPT, AnythingLLM, and self-hosted Open WebUI setups, or consider international alternatives such as Microsoft Copilot and ChatGPT Team/Enterprise.
