Scrivly vs. Westlaw AI
Westlaw AI adds artificial intelligence capabilities to Thomson Reuters\u2019 established legal research platform. Scrivly is a purpose-built AI platform for working with your own documents. These are fundamentally different tools solving different problems.

Purpose-built vs. build-on-top
The difference between adding AI to an existing product and building a product around AI is not cosmetic. It affects every layer of the experience.
AI-first architecture
Scrivly was designed from the ground up as an AI platform for legal document analysis. The document ingestion pipeline, retrieval system, inference engine, and output formatting are all purpose-built. There is no legacy research platform underneath. This allows for architectural decisions like matter isolation, citation traceability, and deployment flexibility that would be difficult to retrofit onto an existing system.
- Primary content: your own documents
- Proprietary retrieval and inference
- Runs on-premise, in cloud, or air-gapped
- No subscription dependencies
AI on top of legal research
Westlaw AI enhances Thomson Reuters\u2019 comprehensive legal research platform with AI-powered search, summarization, and analysis. The underlying content library is unmatched in depth and breadth. The AI capabilities are designed to make existing Westlaw workflows faster and more intuitive, not to replace them or serve as a standalone document analysis platform.
- Primary content: published legal databases
- AI layer on established research infrastructure
- Cloud-only deployment
- Requires active Westlaw subscription
Better together than either alone
We do not position Scrivly as a replacement for Westlaw. They are different tools. Westlaw is for researching published case law and legal authorities. Scrivly is for working with your own documents: analyzing contracts, searching discovery materials, drafting from your case files, and building institutional knowledge.
The firms that get the most value from AI use the right tool for each job. For published legal research, Westlaw\u2019s content library is hard to match. For everything that lives inside your firm, that is what Scrivly was built for.
Who should rely on Westlaw AI
- Firms that primarily need AI for searching published case law, statutes, and secondary sources.
- Organizations already deeply invested in the Thomson Reuters ecosystem.
- Teams that want AI-enhanced versions of existing Westlaw workflows.
Who should add Scrivly
- Firms that need AI for working with their own internal documents and case files.
- Organizations that require on-premise or air-gapped deployment for sensitive matters.
- Firms that want a standalone AI tool without dependency on a research subscription.
Frequently asked questions
Yes. Scrivly and Westlaw serve different functions. Westlaw is a legal research database with AI capabilities layered on top. Scrivly is an AI platform for working with your own internal documents. Many firms use a research tool for case law and a separate tool for document analysis, drafting, and internal knowledge management. The two complement each other.
No, and we would not suggest it. Westlaw provides access to a vast corpus of published case law, statutes, and secondary sources that Scrivly does not replicate. Scrivly is designed to work with your own documents: contracts, briefs, memos, discovery materials, and case files. If your primary need is legal research across published databases, Westlaw remains valuable. If your primary need is AI-assisted work with your own files, Scrivly is purpose-built for that.
No. Westlaw AI is a cloud-based feature of the Westlaw platform. On-premise or air-gapped deployment is not available. Scrivly Local provides a dedicated hardware appliance that runs inside your office with zero internet dependency. Scrivly Secure provides air-gapped deployment for classified environments.
Your clients' confidentiality is not negotiable. Your AI shouldn't be either.
