Tools that query, compare, and synthesize — so every answer earns your trust.
Chat with any LLM. Full model choice, privacy-first options, and switch models mid-conversation. Your gateway to the Nexus ecosystem.
Try Chat →Many LLMs, One Answer. Query multiple models simultaneously and synthesize a single, superior response with confidence scores.
Try Quorum →Deep research powered by multi-provider synthesis. Run parallel research across providers for results better than any single source.
Try Research →AI that acts on your behalf. Long-running tasks, autonomous work with full reasoning traces and auditability.
Try Agents →Quorum exploits a fundamental asymmetry: LLMs are mediocre generators alone, but excellent evaluators together.
Your question goes to multiple AI models simultaneously. Each brings different training data and reasoning.
Each model generates its own answer. Their responses become context for evaluation — where LLMs are strongest.
Responses are synthesized into a single, superior answer with confidence scores, citations, and full reasoning.
Not a wrapper company. We solve genuinely hard AI problems and ship them as accessible tools.
Battle-tested on genuinely hard problems: legal document review, knowledge graphs, KV cache optimization, privacy-first inference.
Not locked into OpenAI or any single provider. Choose your model, switch freely, use local models for complete privacy.
Local models, self-hosted deployment, no data leaving your control. Built for businesses that handle sensitive information.
Not vaporware. Chat, Quorum, Research, and Agents are all live now. Real tools with real value on day one, not slide decks and waitlists.
Every Nexus product is built on a shared platform of advanced AI techniques — not wrappers, but real engineering depth.
Multi-pass verification across models produces higher accuracy than any single model. When multiple models agree with high confidence, that signal is fundamentally different.
Every answer is traceable through the full reasoning chain. Citations, confidence scores, and log probabilities are deeply baked into every response.
Extraction runs on fast, cheap models that excel at the task. Synthesis runs on frontier models. Each stage uses the right tool for the job.
LoRA adapters make models better at extracting and using your information — without adding knowledge to the model itself. Task-specific accuracy on your terms.
Embeddings, vector databases, and knowledge graphs — with techniques that avoid chunking wherever possible for more accurate retrieval.
Open source models enable KV cache optimization and log probability access for confidence scoring and cost reduction that proprietary APIs cannot match.
Consulting reveals real problems. Products solve them at scale. Here's what that looks like.
A mid-size law firm processing thousands of complex documents — scans, handwriting, stamps, and mixed media.
"Turned an accuracy problem into an economics problem by flipping the cost structure of LLM inference."
A content platform needed users to visualize connections between ideas, interviews, and content — not just store documents.
"AI agent captures ideas and remixes content while users visually navigate their knowledge."
A Y Combinator-backed startup needed production-ready AI with verifiable privacy guarantees via secure enclaves.
"Expanded platform support while preserving the encrypted-before-sending architecture."
