ContractAI

Spellbook

Best overall

For most everyday users who need to handle contracts casually, neither tool is ideal because both lack mobile apps and are built for legal professionals. Spellbook wins for anyone already using Microsoft Word and needing fast contract drafting/review, while ContractAI offers a more comprehensive feature set but at an unclear price and with a steeper learning curve. The single biggest difference is that Spellbook works inside Word (familiar and quick), whereas ContractAI is a standalone platform with broader but more complex capabilities.

Common questions

Can I use ContractAI or Spellbook on my phone?

No. Neither tool has a mobile app or mobile-friendly interface. You need a desktop or laptop computer to use them.

Which is better for a small business owner who only needs to review a few contracts a month?

Spellbook is better because you can try it free for 7 days and it works inside Word, so you don't have to learn a new system. ContractAI's hidden pricing and steeper learning curve make it overkill for light use.

Is ContractAI worth the price if I don't know what it costs?

Probably not for an individual or small business. Without published pricing, you risk paying for features you may not need. Start with Spellbook's free trial instead.

Do I need Microsoft Word to use Spellbook?

Yes. Spellbook is a Microsoft Word add-in, so you must have a Word subscription (Microsoft 365) installed on your computer.

Which tool is better for compliance-heavy industries like healthcare or finance?

ContractAI is the better choice because it includes compliance features and risk reports. Spellbook is more about drafting and reviewing, not compliance tracking.

Spellbook wins for everyday Word users who want quick contract help; ContractAI is more powerful but harder to access and afford.

If you're a non-technical person who just wants to speed up contract work without learning a new tool, start with Spellbook's free trial inside Microsoft Word. If you need compliance reports and have a team to support training, consider ContractAI — but ask for a price quote first to avoid surprises.
