Official APIs, not web scraping
SignalKit queries every LLM through its official API. Some competitors scrape the chat UI instead, which produces unreliable data.
API-based (SignalKit)
- Deterministic, reproducible results
- Exact token usage and model version logged
- No personalization, location, or session bias
- Compliant with provider terms of service
Web scraping (other tools)
- Results vary by session, cookies, and IP
- No access to token counts or model metadata
- Personalized responses skew brand tracking
- Breaks when providers change their UI
Research from Stanford HAI and others has shown that scraped LLM outputs are affected by A/B tests, personalization, and regional variation, making them unsuitable for consistent brand monitoring. API access eliminates these variables.

Frequently Asked Questions
Everything you need to know about SignalKit and LLM brand monitoring.
How much does SignalKit cost?
Every new account gets $5 free credit, no card required. $1/prompt/month for 3 core models (ChatGPT, Perplexity, Gemini) and +$0.35/model/prompt/month for extras (Claude, Grok, DeepSeek, Google AIO). Volume discounts kick in at 201 prompts (20% off) and 501 prompts (40% off). No tiers, no contracts.
Which AI platforms do you track?
SignalKit tracks 7 LLMs: ChatGPT, Claude, Perplexity, Gemini, Grok, DeepSeek, and Google AI Overviews. All 7 are available on every account, including free. Pick the models you care about and only pay for those.
Do you scrape the chat UIs or use official APIs?
Official APIs only. We query every LLM through its published API. Scraping chat UIs produces unreliable data because results vary by session, cookies, location, and A/B tests. API access gives us deterministic, reproducible results with exact model version and token counts logged.
How does the REST API work?
Every account gets API keys and full REST API access from day one, including free accounts. Pull visibility scores, sentiment, position data, citations, and raw AI responses programmatically. Most competitors gate API access behind their highest tier.
What is the MCP server?
SignalKit ships an MCP (Model Context Protocol) server that works with Claude Code, Cursor, and Cline. It lets AI coding assistants query your brand monitoring data directly. Set it up once and your agents can check visibility scores, pull competitor data, or trigger audits without leaving your editor.
Can I use SignalKit with AI agents and automated workflows?
Yes. SignalKit is built for agents, not just humans clicking buttons. API keys, structured JSON responses, webhook alerts, and the MCP server make it easy to plug brand monitoring into any automated pipeline. Use it from scripts, CI/CD, or agent frameworks.
What is LLM brand monitoring?
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).
How quickly do I get results?
Your first results appear within minutes of adding prompts. After that, prompts run automatically every day and results update in your dashboard (and via the API).
How is SignalKit different from competitors?
Price, access, and transparency. SignalKit is usage-based from $0 while competitors start at $29-$89/month or require a sales call. Every account gets API access, MCP server, all 7 LLMs, unlimited projects, and unlimited team seats. We also show the raw AI responses so you can verify exactly what each model said.
Can I see the actual AI responses?
Yes. SignalKit stores the full raw response from every LLM we 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.
How does billing work?
Add funds to your account via Stripe ($5 minimum, up to $1,000). We calculate your daily cost based on active prompts and models, and deduct from your balance each day. Set up auto-recharge with a saved card so tracking never stops. Funds never expire. No subscriptions or tiers.
