Langdock is an AI platform from Berlin for the whole company – chat, agents and workflows with models from many providers. c:node sets a different focus: it connects your organisation with law, registers and market and checks every statement against its source.
you want a broad AI platform for all employees – chat, agents and automations with models you can mix and match – and the answers don’t each have to be evidenced.
your questions go beyond your own organisation – law, registers, sanctions lists, public tenders – and every answer has to be evidenced, on-prem up to air-gapped if you wish.
As of October 2026, based on publicly available vendor information. Features may change. Langdock is a trademark of its owner.
Langdock can connect external MCP servers in agents and chat. That way you bring c:node into Langdock as a tool: your team stays in its familiar platform, the evidenced answers come from c:node.
Ask both the same question and see which answer you would sign off on. The sandbox is free.
Langdock is an AI platform for the whole company: chat, agents and workflows with models from many providers. c:node is a Company Brain: it connects your knowledge with law, registers and market and checks every statement against its source.
Langdock fits if you want a broad AI platform for all employees and the answers don’t each have to be evidenced. c:node fits if answers have to hold up before internal audit, regulators or a court – with citations in your documents and in applicable law.
An answer with a citation and a check result: c:node checks every statement against its source – in your documents or in the c:node Graph – and marks anything it cannot evidence as open. You can see what you can rely on and where someone still needs to take a look.
Yes, via MCP. Langdock can connect external MCP servers in agents and chat – your team stays in Langdock and gets evidenced answers from c:node where it matters. The c:node Graph is available via MCP on every plan, questions to your workspace from Starter and the full scope with library, agents, tasks and drafts from Professional; the setup is described in the API and MCP docs.
According to the vendor, Langdock runs as SaaS on Microsoft Azure in the EU; Langdock offers its own-cloud and on-prem options for large enterprise installations. c:node runs in your own tenant in the EU cloud in Frankfurt, in your data centre or – on the Enterprise plan – completely without internet (air-gapped) with open models on your servers.
Both are model-agnostic. Langdock offers models from many providers, also with your own API keys. With c:node, you decide which models are permitted – large models via API or open models on your servers. The check against the source stays the same with every model.
Not yet. Langdock lists ISO 27001 and SOC 2 Type II; c:node is building these certifications up in parallel. Until then, we are happy to go through your requirements directly with your IT security and data protection teams.
