Relex vs Spellbook
What this product is for
Spellbook focuses on AI-assisted contract drafting and review.
Why add—or choose—Relex
Relex addresses the matter around the document: intake, knowledge, structured context and continuing work across compatible agents. A specialist drafting tool may still be useful alongside it.
What to verify before choosing
Test document fidelity, clause review, playbooks and the permitted handover of saved work. An assistant that reads a document is not automatically sharing the same continuing matter record.
Benchmark protocol: prove the handover, not the slogan
