HOW IT WORKS

Connect once, analyze forever.

Authorize Nexus in Box (30 sec)

Go to /settings/dms and click 'Connect Box'. You are redirected to Box's OAuth consent screen — the same flow you already use for Slack or Google. Authorize once, and the connection persists.

Browse your Box folders inside Nexus

Your Box folder tree appears directly inside Nexus. Navigate to any PDF, DOCX, TXT, or MD file without downloading anything to your local machine or leaving the platform.

One click → full legal analysis

Click Analyze. Nexus downloads the file for the duration of the analysis window, runs Node A (primary analyst) + Node B (adversarial audit) in the jurisdiction and legal branch you select, then discards the file. You receive the full report with certainty locks.

WHAT YOU GET

Every analysis. Complete.

🔍

Critical clause identification

Clauses with legal risk, obligations, and critical terms are flagged with certainty locks [L1]–[L5-C]. No generic summaries — every claim is traceable to the source text.

⚔️

Node A + Node B cross-check

Two distinct LLMs contrasting each other: Node A (primary analyst) and Node B (adversarial auditor). Unsubstantiated claims, misattributed locks, and omissions are surfaced explicitly.

🌍

Automatic jurisdiction & branch adaptation

Choose jurisdiction (ES, CO, MX, AR, CL, PE…) and legal branch (civil, criminal, commercial, labour…). The engine loads the correct normative corpus and modules automatically.

📋

Full audit trail with Box metadata

Every analysis includes a structured NEXUS-AUDIT-TRAIL block with Box file_id, last-modified timestamp, and a hash of the processed text. Machine-readable and cryptographically verifiable.

ZERO RETENTION

Your document never leaves Box.

Nexus downloads your file exclusively during the analysis window, processes it entirely in RAM in the Netherlands (Railway europe-west4), then immediately discards it. The only persistent copy of your document remains in Box, under your own retention policies and access controls.

✓Downloaded only during analysis — never stored
✓Processed in RAM, never written to disk
✓No copy persists in Nexus storage — ever
✓Box remains the single source of truth
