PromptSignal at a glance

What to consider

• A 50-prompt Starter sample may not represent the full diversity of customer questions, geographies, languages, accounts, and buying journeys.
• AI answers vary between runs and change when models, retrieval systems, policies, or prompt wording change.
• Visibility and sentiment scores are not the same as market share, search volume, AI referral traffic, leads, revenue, or causal impact.
• Sentiment and ranking classifications can be wrong, so important changes need human review of the underlying answer.
• The public site does not document the exact sampling count, locale, account state, browser use, or weighting behind every reported metric.
• PromptSignal depends on third-party AI systems whose availability and behavior are outside its control.
• Optimization recommendations cannot guarantee that an AI system will mention or rank a brand, and low-quality answer-engine content can damage users and conventional SEO.
• The Starter plan has no published free trial and requires $99 per month for 50 prompts.
• The privacy policy says product and security logs are typically retained for up to 12 months, support records up to 24 months, and aggregated or de-identified data may be retained indefinitely.
• Workspace prompts, outputs, competitor lists, files, and connected sources are Customer Data, so regulated teams should review the DPA, subprocessors, retention, and deployment arrangement.
• The site references SOC 2 standards, but buyers who require assurance should request the current report and confirm its scope rather than relying on a marketing badge.
• Published terms say fees are generally non-refundable and subscriptions can renew automatically unless cancelled under the applicable plan terms.
