Drift puts a chat bubble on your site and runs the same script on every visitor. Cognis scores 15+ intent signals before first contact — then opens with the approach matched to this persona, not a generic opener.
A VP Sales just landed on your pricing page for the third time this week. Here's what each tool does in the next 500ms.

Not marketing copy — these are the actual conversations we have with teams evaluating both.
Drift sits on your page as a passive bubble running the same script for every visitor. Your best leads — the CFO who spent 8 minutes on pricing, the returning buyer from a competitor referral — get the same generic opener as everyone else. Cognis reads who's in the room and adapts before saying a word.
Drift's opening message is the same for a VP Sales on their third visit as it is for a student doing a research project. Percepto's first question already contains the answer — because it reads the context before speaking.
Drift charges per seat — meaning the cost grows as your sales team grows, not as your results grow. Percepto charges per conversation. You pay for outcomes, not headcount.
One script tag. No CRM setup. No playbook sprint. Percepto scores intent and opens conversations from the moment it's live.
