Marble vs Thomson Reuters Checkpoint / CoCOUNSEL
Both help you find the answer. Only one helps you deliver the work.
Thomson Reuters Checkpoint is a comprehensive tax research library with extensive expert-authored analysis and primary-source content. To access its conversational generative-AI experience, firms need Checkpoint Edge with CoCounsel or an applicable CoCounsel Tax plan. Marble is AI-native from day one. Ask a tax question in plain English, receive a citation-backed answer, open the underlying federal or state authority, and turn the research into client-ready work—all through one straightforward platform with transparent pricing.
The Verdict
Checkpoint is the stronger choice for firms that prioritize Thomson Reuters’ extensive proprietary editorial content, practice guides, news, and established research ecosystem. Marble is the stronger choice for firms that want tax research to be faster, easier to use, and more affordable. Instead of navigating a large content library or combining multiple Thomson Reuters products to access generative AI, Marble gives tax professionals one intuitive experience for cited research, primary-source review, work products, and client deliverables.

What’s the difference between Marble and Thomson Reuters Checkpoint / CoCOUNSEL?
Checkpoint is a broad, traditional research platform built around an extensive library of expert-authored tax content. Marble is an AI-native tax research and workflow platform built around getting work done. With Marble, professionals can ask questions in plain English, receive direct answers with citations, open and highlight the underlying authority, and carry that research into memos, emails, and other client deliverables. Checkpoint’s newer AI experiences are available through Checkpoint Edge with CoCounsel and CoCounsel Tax offerings, rather than necessarily being included with every Checkpoint subscription.
