If you are researching Noxtua, you are probably sold on the idea of European legal AI. The data sovereignty argument makes sense and its publisher credentials are strong.

But does Noxtua cover all the jurisdictions your team works in, and does it do enough beyond research and review to justify setting it up? For legal functions that operate across multiple markets, want to empower business teams to self-serve, and are ready to automate the coordination that consumes legal time without adding value, the answer is usually no. In that case, LEGALFLY might be a better fit for you.

For enterprise in-house teams that need more than research and review, LEGALFLY covers the full range: multiple jurisdictions, workflow automation, and regulatory monitoring, with data anonymisation built in. Book a demo.

What is LEGALFLY?

LEGALFLY is a legal AI software based in London and Ghent. Built for enterprise in-house legal, compliance, and procurement teams, it is LLM-agnostic, selecting the best available AI model for each task rather than running a single proprietary model. That means it benefits from advances across the market without locking your team to one provider's capability ceiling.

This tool acts like a legal AI workspace that covers the full range of in-house legal work: playbook-driven contract review with fallback language and escalation logic built in, contract drafting from approved templates in your house style, legal research across 110+ jurisdictions and 500+ official legal sources, multi-document due diligence with risk flagging and insight extraction, and proactive regulatory monitoring through Legal Radar. Agent Studio lets legal teams configure automated workflows from intake to approval.

Every document is anonymised before any AI model processes it. LEGALFLY runs across the full Microsoft 365 stack: Word, Teams, SharePoint, Outlook, Copilot, and Slack.

In-house teams including SAP, Lufthansa, AXA, KPMG, and Bosch currently use LEGALFLY.

What is Noxtua?

Noxtua is a European legal AI platform built around partnerships with established legal publishers. Its flagship product, Beck-Noxtua, integrates with C.H.Beck's beck-online database, one of the most comprehensive legal databases in the German-speaking world. Through a network of publisher partnerships, Noxtua has extended into Austria via MANZ Verlag, Switzerland via Helbing Lichtenhahn, and is in pilot or development phases in Poland, the Czech Republic, and Slovakia.

The platform covers three core functions: legal research drawing on publisher literature, document review with clause validity checks and matrix analysis across multiple documents, and drafting, both in the Noxtua web interface and in Microsoft Word via a Word add-in.

All data is processed on European infrastructure through IONOS and Open Telekom Cloud, with no connection to US cloud providers. Noxtua holds ISO 27001 certification and BSI C5, and is GDPR-compliant. It runs its own proprietary legal language model

Noxtua's proposition is depth in European legal content and sovereign infrastructure. The limitation is scope. Beyond research, review, and drafting, there is no workflow automation, no regulatory monitoring, no structured due diligence capability, and no built-in anonymisation before AI processing.

Noxtua vs LEGALFLY: a direct comparison

Where can you use each platform?

Noxtua works in its web interface and in Microsoft Word. The Word add-in covers drafting and document review, with tracked changes and source citations integrated directly. Beyond Word, there is no broader integration with the Microsoft 365 environment. Routing requests from other business functions into Noxtua, or moving reviewed contracts into an approval workflow, happens outside the platform.

LEGALFLY securely runs across the full Microsoft 365 stack. A contract request that arrives in an Outlook inbox moves through a Word review and into Teams for approval without anyone leaving the tools they already use. SharePoint connects your document repository directly, so review runs on the files where they already live. Business teams submit requests through familiar channels, and legal receives them in LEGALFLY.

Verdict: Noxtua works in Word and on the web. LEGALFLY connects legal to the rest of the business across the full Microsoft 365 environment.

Which platform is better for contract review?

Both platforms let legal teams apply review templates to documents. The difference is what those templates contain and what happens after the review runs.

Noxtua's review uses prompt templates that teams store and reuse for recurring tasks. You define what to check, the AI technology runs the analysis against clause validity and publisher literature, and you get structured output with source citations. The output does not include fallback language, redraft instructions, or escalation logic. Legal still interprets the findings and determines the response.

LEGALFLY's playbooks are built around how your team negotiates, not just what to check. Each playbook includes the clauses to assess the preferred position, fallback wording if the preferred position is rejected, and escalation triggers for deviations that require sign-off. 

The Playbook Builder generates a first-pass playbook from a reference contract you already use, asks a few clarifying questions, and produces a structured review framework in seconds.

You refine it to match how your team actually works, add conditional rules, adjust preferred language, and publish it. Every contract reviewed against it follows the same logic. LEGALFLY also automates the workflow around review, so contracts move from submission through review to approval without manual coordination at each step.

How to build a playbook in LEGALFLY

Start with a reference contract or internal guidance document. The Playbook Builder asks a few clarifying questions and generates a structured review framework in seconds: the clauses to check, the assessments to run, fallback positions, and suggested redraft wording.

From there, refine it to match how your team actually negotiates. Add conditional rules, adjust preferred language, and define escalation triggers. 

Once approved, publish it for use across teams. Every contract reviewed against it follows the same logic, so standards stay consistent as volume grows.

Verdict: Noxtua's technology accelerates clause-level review within a governed template. LEGALFLY reduces the downstream work that still needs doing after the review runs, and automates the process around it.

Which platform is better for legal research?

Through beck-online, Noxtua accesses over 60 million legal documents covering German law, with comparable depth in Austria through MANZ and developing coverage in Switzerland, Poland, Czech Republic, and Slovakia. Coverage does not extend beyond European publishers and the jurisdictions where Noxtua has active publisher partnerships.

LEGALFLY draws from 500+ official legal sources across 110+ jurisdictions, covering legislation, case law, and regulatory guidance sourced directly from government bodies and legal publishers. Research outputs are available in 80 languages. 

Legal Radar extends this further. Rather than waiting for a lawyer to search for regulatory developments, Legal Radar monitors official legislative and regulatory sources and alerts you when changes are published that could affect your contracts or compliance position. It searches your document repository for contracts impacted by a given change, so legal can assess exposure without starting from scratch.

Verdict: Noxtua offers depth in German-speaking European jurisdictions. LEGALFLY covers 110+ jurisdictions from official primary sources and proactively monitors regulatory change to keep your contracts up to date.

Which platform handles volume and due diligence better?

Noxtua's analysis runs across multiple documents of the same type, extracts data, and delivers results in a structured table. For bulk document review within a single jurisdiction, it works. There is no dedicated due diligence capability for M&A or other transactions, and no risk flagging.  

LEGALFLY's Multi-Review Agent runs your playbook across every document in a batch simultaneously and returns outputs ranked by how far each contract deviates from your positions. You see which need attention and which are within range without opening each one individually. For M&A, joint ventures, or portfolio reviews, the same agent runs structured, playbook-based due diligence across an entire document set, flags deviations, extracts key risks, and ranks outputs by severity.

Verdict: Noxtua provides structured multi-document extraction. LEGALFLY applies your playbook across batches, ranks outputs by deviation severity, and handles both day-to-day contract volume and transaction due diligence in the same platform.

Does the platform automate legal workflows?

Noxtua does not offer workflow automation. Templates and prompt libraries operate within the platform. When a contract comes in from procurement or HR, routing it, tracking its progress, and getting it approved happens through whatever tools your team already uses alongside Noxtua.

LEGALFLY's Agent Studio lets you set up end-to-end legal automation. You define the steps, the escalation logic, and who is involved at each stage. A contract request that comes in through Slack or email gets triaged, routed to the appropriate playbook, reviewed by the AI, flagged for legal sign-off where thresholds are met, and returned to the business. Legal retains final approval at every decision point. The coordination around the legal work runs automatically.

Verdict: Noxtua has no workflow automation. LEGALFLY's Agent Studio is a top tool to automate legal workflows from intake to approval across contracts, research, and due diligence.

Which platform protects your data better?

Noxtua runs on European infrastructure through IONOS and Open Telekom Cloud, with no connection to US cloud providers. It holds ISO 27001, BSI C5, ISO 42001, and GDPR certification. Its proprietary legal LLM means no data passes to third-party providers such as Anthropic or OpenAI.

LEGALFLY takes a different approach. Every document is anonymised before it reaches any AI model. Names, commercial terms, and counterparty details are stripped at import as part of the platform's standard processing, regardless of which underlying model handles the task.

This means that even when LEGALFLY uses a US-based model, no identifiable data from your documents reaches it. LEGALFLY holds ISO 27001 and SOC 2 Type II certification, is GDPR-compliant, and offers on-premises and single-tenant deployment for regulated industries where data cannot leave a specific environment.

Verdict: Noxtua keeps all AI processing on European infrastructure with no US provider involvement. LEGALFLY anonymises documents before any model processes them, so no identifiable data reaches the AI regardless of provider.  

How quickly will your team see impact?

Noxtua is designed for individual legal professionals who already know what they need. The interface is clean, the research function is prompt-driven, and teams with existing workflows in the German-speaking legal market can get productive quickly. The Poland rollout is still on a waitlist basis as of spring 2026.

LEGALFLY is designed for fast deployment at team level. The Playbook Builder generates a first-pass review playbook from a reference contract you already use, so your standards are encoded before manual configuration is complete. With 120+ pre-built playbooks across 100+ document types, most teams are reviewing live contracts within the first week. Legal engineering support is included.

Verdict: Noxtua gets individual lawyers productive quickly within supported jurisdictions. LEGALFLY can be used across your organisation within the first week.

Which should you choose?

Noxtua might work if your legal team's work is concentrated in DACH jurisdictions, your primary use cases are legal research and document review, and European infrastructure sovereignty is a procurement requirement. 

LEGALFLY is more useful if you run an enterprise in-house legal function whose contracts touch multiple jurisdictions and you want data anonymisation, proactive regulatory monitoring, and end-to-end workflow automation. Rather than accelerating individual tasks, it governs how work gets done across the organisation, applying your legal standards consistently across every contract.
