Platforms
Choose which AI answer engines Signal tracks for each brand.
What Signal Tracks
Signal asks your prompts on the AI platforms you choose and records every answer. Where possible, answers come from the same consumer apps your customers use, not just a model's API, because the real ChatGPT or Google experience can answer and cite differently. Signal runs all of the collection for you; there are no provider accounts or keys to set up.
| Tier | Platforms |
|---|---|
| Scraped Engines | ChatGPT, Gemini, Google AI Overviews, Google AI Mode, Perplexity, Copilot |
| LLM APIs | Claude, Mistral, DeepSeek, Qwen, Kimi |
Every plan includes three platforms per brand. A new brand starts on ChatGPT, Gemini, and Google AI Overviews. Each platform runs every enabled prompt once a day.
Changing a Brand's Platforms
Open Settings → LLMs for the brand. Tick the platforms to track; the counter shows how many of your plan's platforms you've picked. Changes apply from the next sampling cycle. A brand needs at least one platform to be tracked.
Adding More Platforms
Every platform beyond the three your plan includes is an add-on, priced per plan:
| Plan | Each extra platform |
|---|---|
| Starter | $15/month |
| Growth | $39/month |
| Pro | $79/month |
Buy extra platforms when you choose a plan, or later on the Billing page under Extra platforms. When you add one to an active subscription, Signal shows the prorated charge and asks you to confirm; once you do, it's charged to your card on file right away. See Billing.
Premium Models
Growth and Pro also include premium pairings: grounded, cited answers from GPT Search, Claude (web), and Grok (web), where the model runs its own web search. Each pairing tracks one prompt on one premium model, once a day.
| Plan | Premium pairings included |
|---|---|
| Starter | Not available |
| Growth | 10 |
| Pro | 30 |
Pairings are shared across every brand in the organization. Choose which prompts use them in Settings → Prompts, and see how many are in use on Settings → LLMs. Growth and Pro can buy more pairings for $5 a month each on the Billing page.
