An RB2B alternative that also sees the AI agents
RB2B is built to name the people who visit your site. Knocklog names companies and people too, and covers the part of your traffic RB2B does not: the AI agents that read your pages before a buyer ever arrives. Here is when each one is the better choice.
Checked on 10 November 2026
Summary
If all you want is as many US people named as possible, at the lowest price per name, RB2B is the stronger choice: its Pro plan starts at $149 a month with 600 resolutions, and Pro+ claims 35–45% coverage.
If you want to know how AI assistants find and recommend you, which AI agents are real and which are impostors, and which leads came from ChatGPT, Claude or Perplexity, with companies and US people named in the same report, Knocklog is built for that.

RB2B's coverage rates are the ones it publishes. Knocklog does not publish a coverage rate, because it depends on your traffic: the number of people and companies identified shows up in your report.
Why AI agents matter for visitor identification
A growing share of buying research happens inside ChatGPT, Claude, Perplexity and Gemini. The assistant reads your pricing and product pages for the buyer, who may never visit, or visits later through a link the assistant cited.
A visitor identification tool only sees the visit at the end. Knocklog also shows the reading: which assistants read which pages, how often, whether they were the real ones, and how many people they sent afterwards.
When to choose each
Choose RB2B if:
- you sell mostly to US buyers and want the most people named;
- your team lives in Slack and wants a LinkedIn profile for each visitor;
- name volume each month matters more than understanding your visibility in AI.
Choose Knocklog if:
- you want to see and verify the AI agents that read your site;
- you want to tie each AI assistant to the visits and leads it sent;
- you want companies and some named people in the same report as the agents;
- you run more than one site and want them all on one plan, with no per-domain fee.
Using both
Yes. RB2B's script and Knocklog's collection run on the same site without conflict. If you already use RB2B for name volume, start with Knocklog's free plan to see the AI side.
