What Promptwatch is, and who it is for
Tracking plus content, self-serve. Promptwatch tracks and optimises brand visibility in ChatGPT, Gemini, Claude, Perplexity and other AI search engines. Its plans add agent credits, content gap analysis and, from Professional up, monthly AEO articles.[1][2]
Built for brands and agencies. Plans scale by projects, prompts and seats, with country-level tracking from the first plan and state and city tracking on Business. It collects answers by reading the same chat interfaces people use every day.[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 Promptwatch shines
- You choose the engines. Every Promptwatch plan picks 4 models from a list of nine that includes Meta Llama, DeepSeek and Grok, so a team that cares about one of those can track it from the entry plan.[1]
- Content production in the same subscription. Professional and Business include monthly AEO articles and agent credits, and crawler logs show when AI bots read your site.[1]
- Prices you can read off the page. Plan, price and prompt count are all published, and two of the three plans start with a 7-day trial.[1]
Where Proofsource shines
- A real change, told apart from a wobble. Proofsource asks every question on every engine on a fixed schedule, puts a 95% Wilson interval on every number, and holds alerts until a change clears it. Promptwatch's pricing page does not say how it handles run-to-run variation in answers.
- All four engines free, all ten on Custom. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. Custom covers all 10 engines rather than a pick of 4.
- Seats are not rationed. Custom has unlimited seats. Promptwatch counts seats per plan, from 1 on Essential to 5 on Business.
- The fix starts from the page that beat you. Each Proofsource gap names the pages the engine cited instead of you, with a draft built on what they have, held for your approval.
Proofsource or Promptwatch: the fair verdict
Pick Promptwatch if you want to choose your own four engines from a long list and have AEO articles produced in the same subscription.
Pick Proofsource if the question is whether a change in your AI visibility is real before you act on it, and you want each gap tied to the pages that beat you.
Both re-read answers daily. The difference is what each does with the reading.
