Requirements live everywhere, and nowhere
Word documents, Excel trackers, email threads, a shared drive nobody trusts. The single source of truth is a fiction.
requirements intelligence platform
Trace every requirement, from intent to verified test.
Requilink is the platform for safety-critical requirements: full traceability, immutable baselines, and AI that drafts, never decides. Self-hosted on your own infrastructure. Every feature included, licensed by concurrent seat.

the status quo
Requirements management is broken
Most teams still manage safety-critical specifications across documents, spreadsheets, and email threads, where nothing connects and nothing is certain.
No idea what a change breaks
Edit one requirement and you're guessing what it impacts downstream. Suspect links go unnoticed until an audit finds them.
Proving compliance eats your time
Re-checking impacts by hand, chasing the latest version, assembling the audit trail from scratch. The overhead grows with every requirement you add.
how it works
From chaos to clarity, in three moves
Replace the spreadsheets, the scattered documents, and the manual linking with one connected, auditable model of your requirements.
01
// ingest Import the chaos
Bring in everything: ReqIF, Word, Excel, CSV. The import wizard maps your columns and shows a per-item diff before a single requirement lands.
02
// connect Structure & trace
Requirements become a living graph. Link satisfies, derives, verifies, and refines; let AI flag coverage gaps and suspect links; watch traceability climb across every layer.
03
// certify Baseline & prove it
Freeze immutable baselines, diff any two versions, and keep a complete audit trail: the evidence your certification needs, generated on demand.
capabilities
Built for the full requirements lifecycle
Author, trace, baseline, and review in one platform, with AI assistance, full ownership of your data, and every feature in one licence.
Requirement management
A dense, virtualised module table for 1000+ items. Inline rich-text editing, custom attributes, and colour-coded change bars that show what's new, dirty, or suspect at a glance.
- module table
- rich text
- change bars
Traceability & coverage
Link requirements with satisfies / derives / verifies / refines. Suspect links flag automatically when a source changes. Coverage analysis surfaces every orphan and gap.
- 4 link types
- suspect links
- coverage
Baselines & audit
Freeze immutable snapshots for every release and audit. Diff any two versions visually. A complete, timestamped audit trail records every operation, down to the item.
- snapshots
- visual diff
- audit trail
AI as amplifier
Quality checks, INCOSE compliance validation, link suggestions, and requirement derivation, streamed inline. Every output is a draft the engineer accepts or rejects. Never silent.

Import & migrate
An import wizard for ReqIF, Word, Excel, and CSV with column mapping and a per-item diff preview. Bring your existing modules across with structure and links intact.

Collaboration & access
Document locking so only one writer edits at a time. Threaded comments with @-mentions, real-time notifications, global roles and per-document read / write / admin ACLs.

traceability
Follow the thread from a system need to the test that proves it
Every requirement is a node in a living graph. Link them, and Requilink keeps the chain honest: change a source and downstream links are flagged suspect until an engineer re-validates them. No more silent drift between specification and verification.
- Satisfies, derives, verifies, refines: four first-class link types.
- Automatic suspect detection the moment a linked item is edited.
- Coverage analysis surfaces uncovered requirements and dead ends.

intelligence
AI that drafts. Your engineers decide.
Requilink puts generative AI inside the workflow: quality checks, INCOSE compliance, link suggestions, requirement derivation, and natural-language queries over a whole module. Every output is a reviewable draft, never a silent edit.

- INCOSE compliance
- Derive requirements

// your provider, your data
Configurable across OpenAI, Anthropic, or a fully on-prem model you host yourself. Nothing leaves your network unless you allow it.
deployment
Deployed on your infrastructure. Your data never leaves.
Requilink is installed and runs entirely within your own environment. No SaaS, no third-party storage, no vendor lock-in. Your requirements stay where they belong: inside your network.

Your data, your network
The whole platform runs inside your perimeter: on-premise or in your private cloud. Requirements, baselines, and trace data never leave your infrastructure.
-
No lock-in, ever
Full Word, Excel, CSV, and PDF export. Your data is always yours to take, with no lock-in of any kind.
-
AI on your terms
Point AI at your own on-prem model, or bring your own provider key. Nothing is sent to a third party unless you explicitly allow it.
-
API & automation
A full REST API (OpenAPI) drives every action, so you can automate imports, exports, baselines, and CI checks. A built-in MCP server lets AI agents read and update requirements directly.

questions
Everything you’re probably wondering
What is Requilink?
Requilink is a professional requirements management platform. It lets engineering teams author, trace, baseline, and verify requirements, with AI assistance, while keeping full ownership of their data.
What makes Requilink stand out?
A modern, fast web interface; built-in AI assistance; full traceability with automatic suspect-link detection; immutable baselines and a complete audit trail; one licence with every feature, counted by concurrent seat rather than per named user; and deployment on your own infrastructure.
Can I migrate my existing requirements?
Yes. The import wizard reads ReqIF as well as Word, Excel, and CSV, mapping your columns and preserving structure and links. You also keep full export, so there is never any lock-in.
Where does my data live?
Entirely within your environment: on-premise or in your private cloud. There is no SaaS and no third-party storage. Your requirements never leave your network.
Is my data sent to an AI provider?
Only if you choose to. AI is configurable across OpenAI, Anthropic, or a fully on-prem model you host yourself, and every AI output is a draft your engineers review and approve, never a silent change.
How do I get access to the demo?
Approved companies receive a private demo login from their Requilink provider. Request access, and you’ll be able to explore the full platform with sample projects.
