The website chatbot is what we sell off the shelf; for larger organisations we build AI by hand, on your own data, your own servers and your own workflows.

  • AI that understands your business. Retrieval-augmented generation (RAG) over your own documents, wikis, e-mail and databases, for internal assistants that know your business, in the cloud or on your servers.
  • Customer support and custom AI workflows. Auto-responders that know your inventory, ticket triage and reply drafting, CRM integrations and scheduled workflows, escalating to a human only when needed.
  • Chatbots with no server at all. The model runs in the visitor's browser with a static RAG index, so there is no infrastructure to manage and no inference bill.
  • AI-driven business analytics. Data warehouses, pipelines and dashboards with PII governance, and business questions answered from your own data, with explanations.

The website chatbot and most of our client work run on kavalai, our open-source Python library for agentic workflows. Agents are declared as typed workflow graphs rather than hand-written glue code, and the chat widget on this very page is our own hosted chatbot, built on it. The same building blocks go into client projects, so nothing we deliver depends on a framework we cannot fix ourselves.

Testable

Inputs, outputs and tool calls are typed models, so a workflow has a contract to test against. An evaluation suite replays real conversations before every deploy, and a failing case leads straight back to the run that produced it.

Robust

The model's output is validated before your code sees it. Streaming, retries, rate limiting and sessions are handled by the library, and any provider works behind one interface, so switching models is a configuration change.

Comes with a backoffice

Every session, run, node and model call is recorded and browsable. Conversations lead to runs, runs to tasks, and each task opens into its input and output, so a bad answer can be traced to the node that caused it.
