Priced by the questions you track.
Monitoring is US$3 per question per region per month, all seven AI platforms included: no tiers, no seats, no contracts, and $6 in one-time invoice credit when you sign up. Content & Growth, the half that writes and publishes, is a separate and optional subscription.
Monitoring
The questions you track, per region, per month. Your questions and regions determine the bill; projects and the people you invite have no separate fee.
One account, one bill across all your projects and domains. Add or archive questions anytime; prorated changes appear on your next invoice. A card is required before tracking starts.
Start with $6 in one-time invoice credit. Unused credit carries forward; normal monthly billing continues after it is used.
The audit reads your site in 10 to 20 seconds, with no account.

Signup includes one prompt-suggestion generation and one competitor-suggestion generation per account. The public website audit is free.
Optional add-on: Enhanced measurement
+$10 per active prompt-region / month
Standard Monitoring stays unchanged. Enable Enhanced measurement per project when you want two samples per scheduled run and Claude web search. It is billed on the same Monitoring subscription and can be switched back to standard in Billing.
How access works when you share an account
Two settings, and they are not the same thing. The company role is account-wide: an Owner or an Admin reaches every project in the company, including ones created later, and manages billing, members and API keys. A Member has none of that. The project grant is what a Member gets per project — Viewer reads it and exports what is stored, Editor can also change prompts, brands and settings. You invite by email and pick the grants at the same time; they apply when the invitation is accepted. Nobody is billed for being a member. The ceiling on members comes from the plan configuration on our identity provider, not from a number we set.
What you do not get yet
No single sign-on and no procurement track. Sentiment is scored from a keyword list rather than by a model. There is no combined view across projects, and no benchmark or industry average — we have no consented dataset to build one from, so we do not publish one.
Content & Growth
The half that writes, bought separately and optional. The weekly brief and its findings already come with monitoring.
What it covers
- ✓A weekly plan built from your measurements, at no cost to assemble
- ✓Drafts in your brand's voice from the knowledge you approve, scored and critiqued
- ✓Review and approval before anything is published
- ✓Publishing to a Shopify blog, or to a Git repository behind an Astro site
- ✓A report of which platforms cite each published page
How it is paid for
Choose managed models, or bring an OpenAI, Anthropic or Z.AI key and pay your provider directly. Both use allowance units: one unit is one model call in a workflow, a paid month includes a fixed number of them, and top-up packs never expire. Setting up the brand, its knowledge and your destinations costs nothing, nothing on this page charges you for it, and saved drafts stay readable whether you subscribe or stop. Its current price and included allowance are shown on your billing page before you confirm anything.

Paste any URL and see whether your site is ready for AI to read it, scored out of 100. It reads your pages, robots.txt, sitemap and structured data — it asks no AI platform about you. No signup required.
Frequently asked questions
Pricing, platforms, what is measured, and what is not.
Standard Monitoring costs US$3 per tracked question per region per month, with all seven platforms available at no extra cost. Projects, exports and API access are included, and nothing is billed per seat. Add a question mid-month and you pay the prorated remainder; remove one and the charge stops. Enhanced measurement is an optional US$10 per active prompt-region monthly add-on for two samples per scheduled run and Claude web search. Content & Growth is a separate optional subscription with Managed and bring-your-own-key plans.
New accounts receive $6 in one-time credit toward Stripe invoices. A card is required before tracking starts, and every active question costs US$3 per region per month. Unused credit carries forward; normal billing continues once it is used. There is no recurring free prompt quota. Where Content & Growth offers a trial, it is once per account and card-backed, and renews as a paid plan unless cancelled; Billing shows the plan, the trial length and units, and the renewal price before checkout. The website audit is free and needs no account.
SignalKit tracks seven: ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, Grok and DeepSeek. You can select any of them for a tracked question at no extra cost, because a brand that leads on one platform often trails on another and a single platform is not a sample.
SignalKit uses provider APIs, not consumer chat UIs. ChatGPT, Claude, Gemini and Grok are called through Cloudflare's AI Gateway against each vendor's own API; DeepSeek is a Cloudflare-hosted model; Perplexity is called directly; and Google AI Overviews come from SerpAPI. These are API measurements, so they are close to but not identical to what a person sees in the consumer app. Live provider output can vary between runs, so SignalKit timestamps and stores each response instead of describing it as deterministic.
Every account can create API keys for the supported REST endpoints. Pull mention and cited rates, sentiment, position data, citations and raw AI responses programmatically. Keys can be scoped to a single project, which is useful if you want to give a client a feed of their own data and nothing else.
SignalKit hosts an MCP (Model Context Protocol) connector at https://app.signalkit.ai/api/mcp. Add it as a remote MCP server in any client that takes a URL — Claude, Claude Code, Cursor, Cline — and authenticate with OAuth or a SignalKit API key. It covers projects, monitoring, Content and Growth. The app-operation tools preserve the app's permissions and paid-feature gates: signed in with OAuth, an agent can do what your role allows, and billing changes also need the owner's permission in the app. Over an API key, human-only actions return a link to the app. The separate stdio package exists in our source tree but is not published to npm.
Yes. API keys, structured JSON responses and the MCP server make it possible to query brand monitoring data from scripts, CI/CD or agent frameworks.
LLM brand monitoring tracks how AI assistants like ChatGPT, Claude, and Perplexity mention your brand when users ask questions. As more people use AI for product research and recommendations, knowing when and how AI talks about your brand is essential. This is sometimes called Generative Engine Optimization (GEO) or Answer Engine Optimization (AEO).
Your first results appear within minutes of adding prompts: creating one dispatches it straight away rather than waiting for the next scheduled run. After that the scheduler runs at 04:00 UTC, and cadence differs by platform — five run daily, while Grok and Google AI Overviews run on Mondays and Thursdays. Standard measurement takes one sample per scheduled run. The optional Enhanced measurement add-on takes two and enables Claude web search. Results update in your dashboard and API as they land.
Price, access and transparency. Monitoring costs US$3 per tracked question per region per month, so the bill is arithmetic you can do in your head before you sign up. Every account gets API access, the MCP connector, all seven platforms and up to 999 projects, and nothing is billed per seat. We also show the raw AI responses, so you can check exactly what each platform said rather than taking a score on trust. Where we are behind: there is no SSO and no procurement track, and sentiment is scored from a keyword list rather than by a model. We do not publish benchmarks or industry averages, because we have no consented dataset to build one from.
Mention rate is the share of eligible answers that name your brand: the numerator is the answers naming you, the denominator is the answers we asked for and received in the period. Cited rate is the share of answers whose sources were observable that carry a supported citation to your own domain. New Perplexity Agent measurements distinguish references the answer used from pages it only retrieved; older Perplexity Sonar answers remain not observable because that mapping was not retained. Grok and DeepSeek are observable only when their response carries traceable source links. They are reported separately and they move separately — an answer can recommend you without linking to you, and cite you without naming you as a recommendation. Both are shown with their denominator, so a rate is never a number without a population behind it.
It is made like for like: on the prompts, platforms and regions both periods measured, and the change says so — for example 22 of 24 prompts and 6 of 7 platforms. A platform whose answers fell by more than half is left out and named rather than averaged in, and the change breakdown shows how many points each platform, prompt and topic contributed. When under 70% of this period's answers are in common, or the way answers are captured changed, the change is withheld with its reason instead of shown.
It is the half of SignalKit that writes. To do ranks what to fix from your measurements each week; Content turns it into a plan, drafts pages in your brand's voice from the Brand profile and materials you approve, scores and critiques them, and publishes to a Shopify blog or a Git repository behind an Astro site once a person approves, or leaves the approved text for you to copy out. After publication it reports which platforms cite the page and how its target prompts moved, without claiming why. Drafting and publishing are a separate subscription from monitoring, with managed models or your own OpenAI, Anthropic or Z.AI key, paid in allowance units where one unit is one model call. Setting up your Brand, its materials and your destinations is free, and the current price is shown on your billing page before you confirm.
Yes, and there are two separate settings. The first is the company role: an Owner or an Admin reaches every project in the company, including ones created later, and manages billing, members and API keys; a Member has no company-wide authority. The second is the per-project grant a Member gets — Viewer reads the project and exports what is stored, Editor can also change prompts, brands and settings. Owners and Admins hold no grants because their authority already covers every project. You invite by email and choose the project grants at the same time; they apply when the invitation is accepted. Members are not billed: seats cost nothing, Monitoring is billed by active prompt-regions, while optional Content & Growth has a separate subscription. The maximum number of members comes from the plan configuration on the identity provider rather than from a number we set.
Yes. SignalKit stores the full raw response from each platform query. You can verify exactly what ChatGPT, Claude, or Perplexity said about your brand, see which competitors were mentioned, and check which sources were cited. Citation quality differs by platform: ChatGPT, Gemini, Perplexity and Google AI Overviews return structured source lists. Claude does too when Enhanced measurement enables its web search; standard Claude, Grok and DeepSeek otherwise expose only URLs present in the answer text.
One Monitoring subscription covers the account. Its standard quantity is the number of active prompt-region pairs in switched-on projects: one question in two regions is two units, at US$3 per unit per month. All projects and domains on your account contribute to the same subscription. Adding a question raises the quantity; archiving one, or switching its project off, lowers it. Mid-month changes are prorated on your next invoice, and the billing page breaks down the monthly rate by project. Enhanced measurement is an optional US$10 per active prompt-region add-on on the same Monitoring subscription. It can be enabled per project for two samples per scheduled run and Claude web search. There is no prepaid balance or per-platform surcharge, and each question can use any of the seven platforms at the standard price. AI assistance and deep audits have included usage limits shown on the pricing page. A card is needed before your first question starts running. Content & Growth is a separate subscription on the same billing account and may renew on a different date.
