## Lingvanex

Lingvanex builds language technology that organisations can deploy under their own control. Its flagship offering is on-premise machine translation: software installed on your own servers that translates large volumes of text, documents, and websites across 100+ languages without any data leaving the network. Licensing is fixed-cost with optional perpetual terms and unlimited users.

Alongside translation, the company ships on-premise speech recognition covering 91 languages with automatic punctuation, plus a suite of end-user translators for Windows, macOS, iOS, Android, and major browsers, a Slack translator, and an offline desktop translator. For teams that do not want to run infrastructure, there is a cloud Translation API and SDKs for iOS, Android, macOS, and Windows so translation can be embedded directly into existing products.

Positioning is squarely B2B and compliance-driven. The company publishes case studies spanning automotive engineering documentation, retail service-quality monitoring, and secure language support for government visitors, and organises its solutions around data anonymisation, regulatory compliance, forensic e-discovery, and customer support. Pricing is quote-based, with perpetual licensing available for on-premise deployments.

**Pricing & Plans:** Quote-based enterprise pricing. On-premise deployments are sold as fixed-cost licences with optional perpetual terms; cloud API and SDK pricing is provided on request.

- **On-premise machine translation:** Runs inside your own infrastructure with no internet connection required, translating text, documents, and websites across 100+ languages for unlimited users.
- **On-premise speech recognition:** Self-hosted voice recognition in 91 languages with automatic punctuation, processing audio locally so nothing leaves your network.
- **Translation API and SDKs:** Embed machine translation into existing products without dedicated servers, using SDKs for iOS, Android, macOS, and Windows.
- **End-user translators across platforms:** Apps for Windows, macOS, iOS, Android, and Chrome, Edge, Firefox, Opera, and Safari, plus a dedicated Slack translator.
- **Data anonymisation and compliance tooling:** Designed around regulatory compliance, secure local processing, and forensic e-discovery workflows.

**Strengths:** On-premise and offline options give strong data-sovereignty guarantees for regulated industries; Unusually broad language coverage across both translation and speech recognition; Multiple delivery models—API, SDK, desktop, mobile, browser, and Slack—from one vendor; Fixed-cost licensing with perpetual options suits predictable budgets better than metered cloud translation

**Limitations:** No public price list; everything requires a sales conversation, which slows evaluation; Feature depth per language pair is not documented publicly, so quality must be tested per deployment; End-user translator apps compete with free tools, so the value is concentrated in enterprise features

## Spellbook

Spellbook is an AI contract platform built for transactional lawyers and legal teams. Its core is a Microsoft Word add-in that reviews and redlines agreements, catches risky or non-standard terms, and lets lawyers negotiate from their own side with every suggestion tracked. Alongside the add-in, Spellbook Associate works across multiple documents to help with longer legal matters.

The platform extends beyond single-document review. Teams can draft new clauses and full agreements from LLM output or from saved precedent libraries, compare contracts against industry benchmarks, ask quick questions about complex terms, and encode their standards into playbooks that run automatically on every review. A repository stores signed contracts and monitors them for renewals and new risks, and the company is rolling out Autonomous Contract Management (ACM) to power contracts end-to-end.

Security is a central selling point for legal buyers. Spellbook operates under Zero Data Retention agreements so its LLM providers never learn from, train on or store client data, and it maintains SOC 2 Type II compliance with HIPAA, GDPR and EU AI Act alignment, plus SSO, MFA, encryption and audit controls. It is used by more than 5,000 in-house teams and law firms.

**Pricing & Plans:** Spellbook offers a 7-day free trial for lawyers and legal teams, with extended trials possible for larger organizations. Paid pricing is custom and based on the number of team members on the license; you book a demo for a personalized quote. Free academic access is available for law schools and students.

- **AI review and redlining:** Redline contracts directly in Microsoft Word, catch non-standard terms and negotiate from your side with every tracked suggestion visible.
- **Drafting from scratch or precedents:** Generate new clauses, full agreements and revisions from AI prompts or from your own saved precedent libraries in seconds.
- **Playbooks and benchmarks:** Encode your team's standards into automated checklists that are enforced on every review, and compare contracts against industry benchmarks.
- **Associate multi-document agent:** An AI agent that works through multi-document legal matters with human oversight, plus quick answers to complex legal questions.
- **Legal-grade security and privacy:** Zero Data Retention with LLM providers, plus SOC 2 Type II, HIPAA, GDPR and EU AI Act alignment and enterprise access controls.

**Strengths:** Works inside Microsoft Word, so legal teams keep their existing workflows; Combines review, drafting, comparison, Q&A and playbooks in one suite; Zero Data Retention plus SOC 2 Type II, HIPAA, GDPR and EU AI Act alignment; Trusted by more than 5,000 legal teams with published customer stories

**Limitations:** Pricing is custom and quote-based, so there is no public self-serve price list; Full value depends on adopting the Word add-in and associated workflows; Built for legal professionals, so the learning curve may feel steep for occasional users; Advanced autonomous features like ACM are still being rolled out via early access
