Frequently asked questions

Why can't I just use ChatGPT?

Spellbook is built specifically for contract work. It works directly in Microsoft Word, understands legal drafting context, helps review and redline contracts, compares language to market, and lets your team save playbooks based on your standards. It is designed for legal workflows, not general-purpose prompting.

Is our data safe? We deal with highly sensitive contracts.

Yes. Spellbook is built with enterprise security in mind. It highlights SOC 2 Type II compliance, encryption in transit and at rest, and zero data retention agreements with OpenAI and Anthropic, meaning customer data sent to those providers is not persisted.

How long does it take to get set up?

Getting started is straightforward. Spellbook works directly in Microsoft Word, so your team can stay in a familiar workflow instead of learning a whole new system. Trial users can get access quickly and start reviewing and drafting right away.

How does pricing work for in-house teams?

Spellbook offers custom pricing based on the number of team members on your license. That makes it flexible for teams of different sizes, from smaller legal departments to larger global teams.

Can we build playbooks based on our own standards?

Yes. Spellbook lets you create custom playbooks so your team can save and reuse specific review instructions, preferred language, and internal standards across contracts.
