The verdict

If you're a big firm, Harvey or CoCounsel — the decision is which data ecosystem you already pay for. Small firm doing contracts? Spellbook is the best value on this list, full stop. Don't buy an AI tool for its citations without a citator behind it; a confident wrong citation is worse than no AI at all.
