Keyword allowances are not prompt allowances
Prompt Monitor publishes both keyword and prompt limits, while Digraph publishes tracked prompt and brand limits. A fair comparison should define one shared prompt set, then record how many keyword groups, prompts, engines, markets, and answer refreshes each plan actually supports.
Compare lightweight positions with inspectable evidence
Prompt Monitor positions itself around brand mentions, position tracking, competitor analysis, and analytics. Digraph emphasizes the full answer, cited URL, source domain, competitor framing, and evidence-connected follow-up. Test one prompt where a competitor appears and Digraph is absent, then inspect the raw evidence and export path in both workflows.
Normalize engine modes and collection cadence
Prompt Monitor names ChatGPT, Claude, and Gemini, while Digraph lists nine AI systems. Record the exact model or search surface, geography, language, prompt wording, cadence, answer retention, and citation fields. Engine counts are not equivalent unless the monitored modes and sampling conditions match.
Run a controlled side-by-side pilot
Use the same brand, competitors, buyer questions, markets, language, engines, collection window, and reporting format. Record full answers, brand position, competitor mentions, sentiment, cited URLs, source domains, recommendations, exports, refresh time, and analyst effort before choosing a monitoring workflow.
