How CASUS compares to Spellbook

Spellbook is a contract drafting and review tool used by teams in over 80 countries, but it is not built around German, Austrian or Swiss law and has no Swiss jurisdiction or regional case law behind it. CASUS is built specifically for German, Austrian and Swiss law, with Swiss law at its core.

Spellbook can process documents in many languages and adapt clause wording to different jurisdictions, but it has no database of German, Austrian or Swiss statutes or case law and no dedicated German interface. CASUS gives direct access to over 1.8 million German, Austrian and Swiss court decisions plus statutes, built by lawyers from the region, with the relevant considerations highlighted inline.

Spellbook does not publish pricing and sells through custom quotes. Independent industry estimates put it at roughly USD 99 to 350 per seat per month depending on plan, with enterprise tiers carrying a seat minimum and a multi-month commitment. CASUS is CHF 120 per user per month billed annually, with transparent pricing, no seat minimum and a free trial.

For German, Austrian and Swiss firms, CASUS is a strong alternative: hosting exclusively in Switzerland and the EU, direct access to German, Austrian and Swiss court decisions and statutes, a German and English interface, transparent pricing with no seat minimum, and a native Microsoft Word workflow.

Both use strong security and zero data retention. The difference is data residency: CASUS hosts exclusively in Switzerland and the EU with no US data transfer, while Spellbook — though SOC 2 Type II certified and GDPR-compliant — runs on AWS data centres in Canada and the US, with no Swiss or EU residency option. For Swiss or EU-only residency, CASUS keeps your data in the region by default.

Spellbook is strong for contract drafting, redlining and clause benchmarking, with an agent for multi-document transactional work. CASUS focuses on German, Austrian and Swiss legal work done directly in Word — research, contract review, drafting and proofreading — with an AI data room for multi-document extraction, at a price designed for whole teams.
