Proofsource vs Rankability
Rankability is an agency operating system for AI search: research, content, audits, tracking and client reporting in one platform. Proofsource is narrower: it measures which buyer questions name a brand on four engines and drafts the fix for each gap.

What Rankability is, and who it is for
Built for agencies. Rankability calls itself AI SEO software for agencies, organized around winning clients, delivering AI search visibility and scaling services. Each client gets a workspace for its campaigns, content, audits and knowledge.[1][2]
Tracking inside a wider suite. AI visibility tracking (mentions, citations, competitors, cited sources) sits beside Google rank tracking, keyword research, content creation and optimization, page audits and, on higher plans, technical, local and backlink work.[1]
Education on the top plan. Agency Pro adds implementation education, campaign templates and Gotch Inner Circle coaching and community.[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 Rankability shines
- Client delivery tooling. Client keyword approvals, branded reports with Search Console and Analytics data, and an agency-branded lead generator for prospects.[1]
- Classic SEO alongside AI. Google rank tracking, keyword research and, from Agency, local-grid and backlink monitoring sit in the same plan as AI visibility.[1]
- Coaching for agency owners. Agency Pro bundles implementation education and a coaching community.[1]
Where Proofsource shines
- Engines and cadence stated. Proofsource reads ChatGPT, Perplexity, Claude and Google AI Overviews on the trial and by default on every paid plan, daily if you pick it. Rankability's pricing page does not list the AI engines it tracks, and says tracking frequency will be confirmed before launch.[1]
- Start without a demo. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. Rankability's plans start from a demo booking.[1]
- An interval on every percentage. Proofsource prints a 95% Wilson interval beside every percentage and holds alerts until a change clears it, so a client report does not celebrate noise.
Proofsource or Rankability: the fair verdict
Pick Rankability if you run an agency and want one platform for research, content, audits, rank tracking and branded client reporting, with coaching on the top plan.
Pick Proofsource if you need a precise read of AI answers on ChatGPT, Perplexity, Claude and Google AI Overviews, with the engines, cadence and confidence stated, and a drafted fix for each gap.
