Adding a chat box to an app is easy. Building an AI product people trust and come back to is not. Black River designs and builds software around large language models end to end: the conversation design, the orchestration layer that decides which model sees what, long-term memory that lets the product actually learn about its users, and the guardrails that keep it safe, private and affordable at scale.
What we build
- Conversational products – assistants and companions with voice, structured long-term memory and personalisation.
- AI features in existing platforms – summarisation, classification, search over your own documents (RAG), extraction from messy inputs.
- Agents and automation – tool-using workflows that call your APIs, with human review where it matters.
- Safety and privacy engineering – risk detection, content moderation, encryption, data export and deletion, audit trails.
- Evaluation and cost control – test suites for prompts and models, caching, model routing and usage monitoring.
We work with the leading commercial model providers as well as open-weight models when data has to stay in-house, and we ship on web, iOS and Android.
