NEXUS

A project by Qalarc — AI systems studio, Sydney, Australia. Built, shipped and maintained by Qalarc.

A graph-first OSINT investigation workbench: collect entities through a scanner hub, flowsint enrichers and recursive research agents; link them into an evidence graph with full provenance; triage leads with calibrated decision engines; and export evidence-backed dossiers and article briefs.

What it does

• Two layers, one stack — the OSINT Hub runs the scanners (sherlock, maigret, phoneinfoga, ignorant, holehe, revimg); NEXUS turns every finding into entities, typed relations and evidence with tool + URL provenance.
• Connector engine — hub scans, flowsint enrichers (subdomains, WHOIS, ASN, breaches, crypto), OpenPlanter recursive research agents, and archon canon grounding — all as async tasks with live log streams.
• Calibrated decisions — lead triage and same-entity merge gates run through a chain of Jev (remote, calibrated) → Laya (local, fine-tuned on logged decisions) → deterministic heuristic. Every decision is logged for the next fine-tune.
• Graph intelligence — shortest-path connection finding, PageRank centrality, community detection and connector-aware pivot suggestions.
• Journalism exports — dossiers with evidence appendices and article briefs with lede angles, nut graf, and a claim ledger marking every claim Supported / Single-source / Unverified.
• Agent-native — a 16-tool MCP server lets archon agents and AI pipelines drive investigations directly.

Try it

The workbench runs fully client-side. When our public sandbox is online, the demo link connects to it automatically — bring your own Jev key (Settings → jev_api_key; it stays in your browser and calls TypeSafe directly) for calibrated lead triage and same-entity merge checks. Otherwise it starts unconnected: point it at your own nexus-server via ?api= or Settings → API base.
