Suite Overview
ChatGPT is where lawyers start — but not where they stay. While powerful, it’s built for general use, not tuned for the nuances of legal drafting, reviewing, and negotiating or integrated in Word.
Spellbook goes deeper. Purpose-built for transactional law, it's packed with features that matter in contract work—precise redlining, benchmark comparisons, and clause-level Q&A right in your document.
ChatGPT is a blank canvas. Spellbook is a legal-first command center.

How it works
AI Models and Functionality
ChatGPT offers a single powerful model while Spellbook is model agnostic, pulling the best LLM for the job. This multi-model approach means better coverage, deeper understanding, and more reliable results across contract types and jurisdictions.
Spellbook is also built for legal nuance, not generic generation. Advanced redlining, customizable playbooks, and clause drafting are deeply integrated, letting you move seamlessly from first draft to final markups.
Spellbook's Word add-in is key for legal teams, cutting down on tab switching and copy/pasting.

User Experience and Setup
Getting started with ChatGPT is simple, and beats Spellbook in quick, out of the box setup time. However, legal teams on Spellbook benefit from training and support.
Spellbook wins in workflow efficiency, and as mentioned prior, legal specific functionality. One key area is prompt engineering, with specific features acting as a shortcut to mastery. For example, lawyers can run a detailed negotiation focused contract review in one click, versus prompting for the same outcome.
Security
Trust and Compliance
Both platforms feature a reliable and secure platform, boasting SOC2 and Zero Data Retention. However, security protocols on ChatGPT will depend on the plan and set-up by the user, Spellbook is secure by default.
