Deep dive: AI-native vs. legacy add-on
Built for AI from day one
Scrivly was designed as an AI platform from the ground up. Every piece of the system is built to keep hallucination rates below 0.5% and to trace every claim back to a specific source. The platform covers 792 document types across 22 practice areas and includes 137 pre-built workflows, with the ability to create unlimited custom workflows that reflect how your firm actually works.
AI layer on a proven platform
CoCounsel adds AI capabilities on top of Thomson Reuters\u2019 decades-old legal research infrastructure. This approach benefits from the breadth and depth of Westlaw\u2019s content library. The trade-off is that AI functionality is constrained by the architecture of the underlying platform, which was not originally designed for AI-first workflows.
Deep dive: Legal corpus and accuracy
Every published opinion, plus your own files
Scrivly gives you access to every published court opinion alongside your own uploaded documents: contracts, briefs, memos, discovery materials, and internal research. With a hallucination rate below 0.5%, you can trust that every response is grounded in real authority. You always know exactly what sources informed every answer.
Westlaw is the source
CoCounsel\u2019s primary content source is Westlaw\u2019s database of published case law, statutes, secondary sources, and Practical Law resources. This is extremely valuable for legal research. However, it means that working with your own internal documents is not the primary use case, and access requires an active Thomson Reuters subscription.
Deep dive: Workflows and adaptivity
A platform that learns how you practice
Scrivly ships with 137 pre-built workflows covering common legal tasks, and you can create unlimited custom workflows on top of that. Over time, Scrivly learns how your firm works and creates custom workflows automatically based on your patterns. The platform gets more useful the longer you use it, not just faster at the same things.
Guided research within a fixed framework
CoCounsel provides a set of AI-powered skills within the Thomson Reuters ecosystem: document review, legal research, contract analysis, and drafting assistance. These capabilities are useful for firms already on Westlaw. However, the workflow options are defined by the platform rather than shaped by how your firm actually practices.
Who should choose CoCounsel
- Firms already invested in the Westlaw ecosystem that want AI-assisted legal research.
- Teams that primarily need AI for searching published case law and secondary sources.
- Organizations comfortable with cloud deployment and vendor-managed infrastructure.
- Firms that value the depth and breadth of Thomson Reuters\u2019 content library.
Who should choose Scrivly
- Firms that demand verifiable accuracy and need a hallucination rate below 0.5%.
- Practices that need broad document generation across 792 types and 22 practice areas.
- Firms that want workflows that adapt to how they actually practice, not a fixed set of features.
- Organizations that want access to every published court opinion alongside their own files, without vendor lock-in.
