Best-fit profile

Choose Vallor when…

You need answers across signed contracts spread over CLM, ERP, shared drives, email, and procurement systems, not help drafting one document.
Procurement owns the pain: missed renewals, auto-renew traps, vendor risk, SLA gaps, and savings leakage.
You want a coworker in email, Teams, and Slack that the whole team can ask, not a tool only lawyers open in Word.
You need obligation tracking and monitoring that runs after signature, every day, without someone re-opening the file.
You want value this quarter and cannot wait for a precedent-library setup or a seat-by-seat rollout.

Choose Spellbook when…

Your team's main job is drafting and redlining contracts, and you want AI help without leaving Microsoft Word.
Your lawyers want clause generation, market benchmarking, and a Playbook that redlines the way your GC would.
You work pre-signature: intake, first-pass review, and negotiation are where the time goes, not portfolio monitoring.
You want AI to learn from your own precedents and reuse past language inside the document you are editing.
Word is the system of record for your drafting, and switching your lawyers to a browser tool would slow them down.
