What RankLLM is, and who it is for
A score and a marketplace. RankLLM calls itself an LLM rank tracker and AI-powered listicle marketplace: a Brand AI Score shows how often ChatGPT, Gemini and Claude mention you, and the marketplace lists 'best X' articles where your brand could be added.[2]
LinkRadar scans. Paid plans unlock LinkRadar scans that find niche edit and listicle placements on a target domain, with a rewritten sentence or list item and a ready-to-send editor brief.[1]
For link builders and agencies. Plans scale by brands and scans, from one brand on Starter to fifty on Agency, so it suits marketers and agencies running citation building.[1]
Proofsource is an AI intelligence platform that shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, and exactly what to fix.

Where each shines
Both tools are built well for different teams. Each point is a strength, read from that vendor's own pages.
Where RankLLM shines
- A direct route to listicles. It finds the roundup articles where competitors appear and you do not, and gives you the exact list item and an editor brief.[1]
- Low prices, free marketplace. Plans start at a low monthly price and the marketplace is free for everyone.[1]
- Many brands on one plan. Professional tracks ten brands and Agency fifty, with unlimited Brand AI Score checks.[1]
Where Proofsource shines
- Four engines, re-read daily. Proofsource reads ChatGPT, Perplexity, Claude and Google AI Overviews, every day on Custom. RankLLM's score covers ChatGPT, Gemini and Claude and is checked when you run it.
- Every winning page, not one lever. Listicles are one kind of page AI cites. Proofsource names every page the engines cite instead of you, so you can see whether a listicle, a review site or a vendor page is the cheapest gap to close.
- A free trial of the full report. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. RankLLM has no free trial of its paid plans.

Proofsource or RankLLM: what buyers ask
Knowatoa vs Otterly.AI for tracking daily changes in AI visibility: which is better?
We have not verified those two tools' plans here, so check their own pricing pages. For daily changes, look for a tool that re-reads on a schedule: RankLLM's score is checked on demand, with monthly suggested as a baseline, while Proofsource re-reads every day on Custom and flags a change once it clears a 95% Wilson interval.
Which AI engines does RankLLM check?
The Brand AI Score covers ChatGPT (GPT-4o mini), Google Gemini and Anthropic Claude. Proofsource reads ChatGPT, Perplexity, Claude and Google AI Overviews on every plan.
Does RankLLM have a free trial?
No free trial for paid plans, per its pricing FAQ, but the Brand AI Score check and the listicle marketplace are free. Proofsource's trial: 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call.
Do listicle placements really improve AI visibility?
They can: listicles are among the pages AI engines cite for 'best X' questions. Which pages matter differs by category, which is why Proofsource names the specific pages winning each of your buyer questions before you spend on placements.
