What Citlyze is, and who it is for
Track, catch errors, fix. Citlyze tracks how ChatGPT, Gemini, Perplexity and Google's AI surfaces mention, cite and rank a brand, flags what they get wrong, and turns each gap into pages to fix, sources to win and drafts to publish.[2]
Plans by prompt volume. Starter tracks 5 daily prompts, Growth 20 and Pro 40, each run across every engine in the plan, with competitors, seats, audit credits and history growing by tier.[1]
Brands and agencies. Brand plans cover one workspace; agency plans add client workspaces, a pooled prompt allowance, client viewer seats and white-label reports.[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 Citlyze shines
- A wide engine list from the entry plan. Starter includes ChatGPT, Gemini, Perplexity, DeepSeek and ByteDance daily, and Google AI Overviews, AI Mode and Bing Copilot weekly.[1]
- Data plumbing included. Growth adds a read-only REST API, an MCP server and scheduled reports; Slack and Teams delivery is on every plan.[1]
- AI traffic and bot access. Plans track AI referral traffic and conversions and monitor whether AI bots can reach your pages.[1]
Where Proofsource shines
- Claude, and Google AI Overviews daily. Proofsource reads ChatGPT, Perplexity, Claude and Google AI Overviews on every plan, and daily on Custom. Citlyze does not list Claude, and checks Google AI Overviews weekly.[1]
- More questions in the trial. The Proofsource trial runs 25 buyer questions on 4 engines on 2 days. Citlyze's trial carries Starter limits of 5 daily prompts.[1]
- The interval, published. Citlyze samples each prompt several times per run. Proofsource prints the 95% Wilson interval beside every percentage, so you can see how sure a number is before acting on it.[1]
