Requirements made simple
A requirements management platform for systems engineering that brings your teams and supply chain together in one simple platform. Built for project teams, system engineers, and asset owners in regulated industries.
Stop Juggling Spreadsheets — Get One Source of Truth
Tired of hunting through emails and spreadsheets for the latest requirements? Reqi is a requirements management platform that gives your entire team — from system engineers to supply chain partners — instant access to real-time compliance tracking, progress monitoring, and system-level views. See exactly what needs attention, who's responsible, and what's at risk — all in one platform that anyone can use from day one.
Write Better Requirements in Seconds — Not Hours
REX is Reqi's free AI-powered requirements quality tool. It analyses your requirements against the INCOSE 42-Point Guide and instantly shows you what's wrong and how to fix it. Upload any document and REX extracts requirements, identifies gaps, flags ambiguities, and suggests improvements — all based on systems engineering best practice.

Built on Systems Engineering Principles
Reqi is purpose-built on INCOSE systems engineering principles to manage complex projects from concept to delivery. Track requirements through the entire V-model lifecycle, maintain compliance traceability across your supply chain, and identify risks before they derail your timeline.
Let AI Do the Heavy Lifting
From a blank page to a structured, traceable system — Reqi's AI builds and visualises your architecture so you can focus on engineering decisions, not data entry.
Build Your System Breakdown Structure with AI
Start from a top-level need and let Reqi's AI propose a complete System Breakdown Structure — decomposing your system into subsystems and components, suggesting boundaries, and allocating managers and reviewers as it goes. The decomposition follows INCOSE systems engineering principles, so your structure is aligned with recognised best practice from the outset. What used to take a systems engineer days of whiteboarding takes minutes, giving you a coherent, traceable hierarchy to refine instead of a blank page.
Visualise Your Requirement Architecture at a Glance
Reqi's AI maps every requirement to its place in the system architecture and renders an interactive network diagram of the whole programme. Built on INCOSE systems engineering principles, it lets engineers instantly see how requirements cluster around each subsystem, trace dependencies across interfaces, and spot orphaned or over-loaded elements — turning thousands of rows into a single picture of system health and coverage.
Allocate Requirements Down Every System Level
Reqi's AI flows each high-level requirement down through the system hierarchy — deriving subsystem and component sub-requirements and allocating them to the right part of the architecture, level by level. The approach is aligned with INCOSE systems engineering best practice, giving you full top-to-bottom traceability from the parent need to every derived requirement, so nothing is dropped and every allocation is justified.
Risk and Traceability
Track assumptions, constraints, and dependencies throughout the project lifecycle. Define and track acceptance criteria across multiple parties with requirements traceability throughout the supply chain — identifying and mitigating risks early before they cascade.
Identify Hazards and Manage Safety Risk
Track safety requirements alongside assumptions, constraints, and dependencies throughout the project lifecycle. Reqi helps project teams identify hidden risks and implement mitigation measures progressively — from HAZOP and FMEA outputs through to verification evidence and safety case closure.
Contract Requirements Management
Bulk import contract requirements and track compliance with system-level views across your supply chain. Analyse relationship structures to understand how different parts of the system interconnect — and surface risk before it becomes a problem. Manage pre and post contract award with full traceability from specification through to acceptance.
Analyse
Requirement analysis and allocation with responsibilities. Capture risk and assumptions progressively.
Traceable
Traceability up and down the project lifecycle, including allocation of responsibilities across the supply chain.
Visualise
Visualise your system architectures and inter-dependencies, with quick access and tracking of progress.
Extract Requirements from Any Document
REX scans and analyses any PDF — contracts, specifications, standards — and extracts a structured list of requirements. No manual data entry. Use our free AI-powered requirements management tool to automate and define requirements from your briefs, specifications, and reports.

Reporting and Dashboards
Monitor compliance traceability using system-level views across the supply chain. Visualise system architectures, requirement allocation, and packaging — so teams can see the entire system and identify areas of risk or non-compliance at a glance.
Bring Your Supply Chain Into One Shared Space
Manage supply chain requirements by giving every stakeholder — internal teams, contractors, and suppliers — access to the same real-time information. Track who's responsible for what, visualise dependencies between teams, and catch problems before they cascade into costly delays. No more version control nightmares or "that wasn't in my scope" arguments.
