Which should you choose?
LlamaIndex is the lighter-weight option (Freemium), while Spellbook sits higher on the pricing ladder (Enterprise). LlamaIndex is built around teams building rag over internal data; Spellbook leans more toward small and mid-size law firms doing transactional work. Shortlist the one whose strengths line up with your biggest constraint.
