SignalKit review: pricing, features & alternatives

signalkit.ai/pricing (read 20 October 2026). Monitoring: $39/mo including 10 prompts, then $3/mo per additional prompt, counted once per country. SignalKit says each prompt yields about 250 answers a month across the nine platforms. Its example bills are $84 for a solo founder, $369 for an in-house team and $3,429 for an agency with 12 clients.

Included AI assistance scales with every 10 paid prompts: 2 site audits, 20 prompt suggestion runs, 1 recommendations run per 7 days, 2 competitor comparisons and 20 change explanations per 30 days. Content & Growth is a separate line: $99/mo managed for 150 units, or $29/mo on your own model key for 600 units of keyword data. Top-ups are $29 for 40 managed units or $19 for 400 BYOK units.

ChatGPT, Claude, Gemini and Grok go through Cloudflare's AI Gateway against each vendor's API, DeepSeek runs as a Cloudflare-hosted model, and Perplexity is queried directly. Copilot, the logged-out ChatGPT app and Google AI Overviews are read from the live interfaces in the prompt's country. Every response is timestamped and stored, so you can audit any figure.

SignalKit publishes a comparison page against other trackers. Treat it as vendor material.

Every row below is a capability we already listed for SignalKit. It is the published feature set for this page, not a guess at an unpublished demo. Compare it with the Promptwatch checklist that follows.

On this listing, SignalKit is a AI visibility platform for Small B2B and ecommerce teams that want wide engine coverage and API access on a budget, and are fine with API-sourced answers for most platforms. What we sourced here: Nine AI platforms per prompt: ChatGPT, ChatGPT (app), Perplexity, Gemini, Claude, Google AI Overviews, Grok, DeepSeek and Copilot; Mention rate, cited rate, position, three-way sentiment and share of voice, with like-for-like period comparisons; Change breakdowns by platform, prompt, topic and source, plus a weekly Monday brief; REST API and hosted MCP connector on every account; Content & Growth add-on: drafts pages and publishes to Shopify or GitHub-hosted Markdown and HTML sites.

If you buy SignalKit for the job above, plan a second tool (or Promptwatch) for the layers this listing does not document. Still missing here: AI crawler logs (Agent Analytics), crawl-to-citation path, bot errors; Visitor analytics: AI-referred sessions and conversions; Content Agents that plan, write, and publish GEO pages to a CMS with a review inbox; Citation analytics at page, domain, Reddit, YouTube, and offsite level; Prompt volumes, difficulty, query fan-outs, personas, city-level geo; Prompt and citation trends (what changed between checks); ChatGPT Shopping tracking and Ads Radar; Agent Chat, Unified Actions, MCP server / REST API on paid plans. Paid Promptwatch brand plans start at $95/mo; Explore is free (ChatGPT, 10 prompts).

SignalKit's public pages (and this listing) describe a narrower job than Promptwatch. Most rivals answer whether you were mentioned. Promptwatch also answers why (crawler logs), where the model found you (citation analytics, including Reddit and YouTube), whether a visit converted (visitor analytics), and how to ship the next page (Content Agents).

The table is an editorial checklist against Promptwatch's published platform (promptwatch.com/llms.txt, 2026-08-23). It is not a hidden feature list for this vendor. 'Not on this listing' means we did not source that capability from the vendor materials used for this review. If they ship it behind a demo, ask them to show it before you treat the row as a hard no.
