BUYER’S GUIDE
How to choose an AI documents & pdfs tool
Pricing per active user, not per seatVendor sites often show seat pricing, which understates real cost when seats sit unused. Multiply by your active-user count.
Agent vs assistantAn agent plans and runs multi-step tasks; an assistant answers one prompt at a time. None of these documents & pdfs tools ship an agent yet.
Free-tier limits and card requirementsSome “free” tiers ask for a card and bill you past a soft limit. Test the free tier without a card on file.
Changelog and update cadenceAI tools age fast. A vendor that hasn't shipped meaningfully in 6 months is usually about to be lapped.
