PromptSignal
PromptSignal is an AI visibility analytics platform that queries ChatGPT, Claude, Perplexity, Gemini and other leading models daily to show how they mention, rank and describe your brand, built for brand, product and growth teams.
What is PromptSignal?
PromptSignal is an AI visibility analytics platform: it monitors how large language models mention, rank and describe a brand when buyers ask them questions. The premise on the homepage is blunt, your customers are asking AI, not Google, and the product exists to answer three questions classic tooling leaves open. Is your brand cited on the prompts that matter? How does it rank against competitors? Do AI answers help or hurt the way you are perceived? As the site puts it, traditional SEO and PR tools do not tell you how AI models perceive your brand.
The workflow has four stages. You choose the prompts to track, helped by curated suggestions matched to your business. The platform then queries the leading models on your behalf, daily on the Starter plan and hourly on Enterprise, across OpenAI, Gemini, Perplexity, Anthropic, Google, xAI, DeepSeek, Mistral and Llama. Results feed five named metrics: Brand Visibility for how often you appear, Competitor Tracking for how you compare, Sentiment Score for the tone of each mention, Ranking Position for where you land in AI-generated lists, and Prompt Performance for prompts won and lost. From there the tool produces content briefs and drafts written for answer engines, plus tailored technical recommendations for improving presence.
The audience named on the site is brand, product and growth teams, and the terms restrict the service to business use. Access is through a web application; there is no mobile app and no public API documentation. The commercial posture is still early access: the company says it is currently onboarding early users and brand teams who want to shape the future of LLM visibility analytics, and the way in is a waitlist form or a demo with the founders rather than a self-service checkout.
PromptSignal is published by Dynamiq Technologies Inc. and built on the Dynamiq platform. The site advertises SOC 2 and GDPR compliance and publishes a subprocessor list. The terms are candid about the limits: no outcome is guaranteed, and LLM-derived analysis may contain inaccuracies, hallucinations or gaps.

- A single public price point at 99 USD per month, Enterprise quoted on demand, and no free plan or announced free trial
- The Starter plan caps tracking at 50 prompts
- No public API documentation, even though the terms refer to APIs and API keys

Pricing & Plans
No free plan is advertised on the pricing page and no free trial is announced. The lowest entry point is the Starter plan at 99 USD per month, which includes unlimited users, 50 tracked prompts, daily updates and email support. The Enterprise plan is priced on demand. Both plans are subscribed through a demo request rather than a direct online checkout. Fees are billed in advance, monthly or annually, and renew automatically until cancellation. They are non-refundable except where the law requires otherwise or where a material breach remains uncured, late payments carry interest of 1.5% per month or the maximum legal rate if lower, and applicable taxes are payable by the customer.

Data, GDPR & hosting
A consolidated view of how PromptSignal handles your data.
GDPR overview
GDPR implementation is documented rather than merely claimed. The homepage states that data is safeguarded through secure processing with mechanisms for exercising GDPR rights, alongside a SOC 2 claim. The privacy policy sets out legal bases field by field (contract, legitimate interests, consent, legal obligations), separates the controller role for site and account data from the processor role for Customer Data, and offers a DPA on request. Transfers rely on EU Standard Contractual Clauses and comparable UK addenda, with the EU-US Data Privacy Framework also cited. Rights are exercised by emailing the legal contact with the subject Privacy Request. A public subprocessor list is published and Global Privacy Control signals are honored. However, no Article 27 EU representative and no data protection officer are named, and no SOC 2 report or ISO certificate is downloadable.
Who owns the data?
Under section 3.1 of the terms of use, you keep all rights to the content, data and files you submit, which the agreement calls Customer Data. Section 3.2 grants the publisher a worldwide, non-exclusive, royalty-free license to host, process, display and use that material solely to provide and maintain the service and to handle security or technical incidents. The publisher and its licensors retain ownership of the platform itself, including software, algorithms, models and documentation (6.1), and any feedback you send transfers a perpetual, irrevocable, royalty-free license (6.3). The privacy policy positions Dynamiq as processor for Customer Data, your organization remaining the controller, and limits processing to documented instructions.
Reuse rights
Customers may use the service and its outputs for their own internal business purposes throughout the subscription, under the limited, non-exclusive and non-transferable right granted by section 6.2 of the terms. Nothing restricts internal reuse of the reports, briefs and drafts produced for your brand, and section 3.4 lets you export available Customer Data through the tools provided while the subscription is active. Two hard limits apply. You may not use automated means to scrape or extract data from the Service except through documented APIs and within granted limits, and you may not build a competing service out of the platform or its outputs. After termination, Customer Data is deleted or de-identified within a reasonable period, except where legal retention or legitimate records such as billing and security logs apply. Section 1.4 also warns that LLM-derived analysis may be inaccurate or incomplete, so outputs are worth checking before you republish them.
Data retention & training
Hosting summary
Hosting runs on the publisher's infrastructure rather than a region you choose. The subprocessor list names Amazon Web Services for cloud infrastructure and hosting via Dynamiq, and Supabase for database and data storage, both with processing locations in the United States and the European Union. Model processing goes to OpenAI OpCo, LLC and Anthropic, PBC in the United States. Around them sit analytics tools (Google Analytics, Hotjar in the EU, Segment and Twilio), support and communication services (Customer.io, Tidio, Google Workspace, Slack, Calendly, Fireflies.ai), payments through Stripe, and engineering services from Sentry and GitHub, spread across US and EU processing locations with an executed DPA for each. The privacy policy confirms that international transfers may occur, including to the United States, and relies on EU Standard Contractual Clauses with comparable UK addenda, citing the EU-US Data Privacy Framework as an additional route. No hosting region choice is offered anywhere on the site, and the contract is governed by the law of the State of Delaware.
Things to keep in mind
Risks and trade-offs to weigh before adopting PromptSignal.
- The terms guarantee no outcome and warn that LLM-derived analysis may contain inaccuracies, hallucinations or gaps, so the scores are signals rather than measurements
- Model answers vary from one run to the next and shift with every model update, and steering brand strategy on unstable metrics can build false confidence
- Optimizing for answer engines can crowd out editorial judgement, turning content into machine-facing filler that real readers do not value
- The service depends on third-party models and sources whose availability and behavior are outside the publisher's control
- Customer Data may incidentally contain personal data if your team submits it, and filtering that out remains your responsibility
- AI subprocessors sit in the United States, so data leaves the EU under standard contractual clauses, which deserves its own assessment
- Subscriptions renew automatically until cancelled, your name and logo may be used as a commercial reference unless you opt out by email, and beta features are provided as-is and can be suspended at any time
Setup & Integrations
Technical difficulty
Low. There is nothing to install: PromptSignal is a web application reached after registration or a demo. Setup means naming your brand, listing the competitors to follow and picking the prompts to track, guided by curated suggestions. The collected pages show no code to write, no tag to place and no technical integration to configure. Only the Enterprise options, SSO and on-premise deployment, call for IT involvement. In practice the current path runs through a conversation with the team, which removes almost all technical friction but adds waiting time before you can start.

Should you pick PromptSignal?
PromptSignal addresses a genuinely new problem. As buyers increasingly build their shortlist by asking an assistant instead of searching, brands lose sight of a decision moment that classic SEO and PR tools never measure. Tracking nine model families daily, then scoring mentions, rank, sentiment and prompt-level performance, is a serious answer to that gap and clearly beats checking prompts by hand.
Two things temper the picture. First, access: the product is still in early access, gated by a waitlist and a demo with the founders rather than open sign-up, and the pricing is thin, with a single public tier at 99 USD per month capped at 50 prompts, Enterprise quoted on demand, and no free plan or announced trial. Second, the thinness of the public surface: there is no about page, no contact page, no support address beyond the legal one, no social accounts and no API documentation, even though the terms mention APIs and API keys.
Against that, the compliance groundwork is unusually solid for a product this young. The domain was registered in July 2025 and the legal documents date from August 2025, yet you get quantified retention periods, a clear controller and processor split, a DPA on request, standard contractual clauses for transfers and a public subprocessor list naming each vendor's legal entity and processing location. Unlimited users at the entry tier, plus SSO and on-premise deployment on Enterprise, are real differentiators too.
One caveat is worth keeping in mind: the terms themselves state that no outcome is guaranteed and that LLM-derived analysis may be inaccurate or incomplete. Treat the metrics as directional signals rather than certified measurements. For a brand, product or growth team that wants an early read on AI visibility and can live with an early-access supplier, PromptSignal is worth a demo.
