## What to watch for

- **Ahrefs Brand Radar**: Ahrefs' pricing is in EUR on the vendor site (re-verified directly on ahrefs.com/brand-radar, 2026-08-23). USD figures in older reviews reflect an earlier Ahrefs pricing page that has since moved to euro pricing. The €179 (about $201)-per-surface and €654 (about $733)-bundle totals are confirmed on the live product page and corroborated by independent third-party reviews from early 2026.
- **Promptwatch**: Essential plan is capped at 50 tracked prompts and 1 website, which is thin for brands with multiple product lines.
- **Keyword.com AI Visibility**: Exact credit cost per AI-engine query isn't published, making it hard to predict usage against the 20-credit trial allotment or a plan's monthly credit cap
- **Rankscale**: No GA4 or analytics integration for connecting AI visibility to traffic or revenue

Best match first.

## Shortlist

### 1. Ahrefs Brand Radar

AI visibility tracking across six AI answer platforms, sold as an add-on to an Ahrefs subscription.

**Where it improves on SerpApi:**
- [Monitors AI answers: yes — Its core job is watching AI answers: the vendor runs a standing index of search-backed prompts through the AI platforms and stores every response, so mentions and citations are counted for any brand you enter.](https://ahrefs.com/brand-radar)
- [ChatGPT: yes — ChatGPT is one of the six platforms in the pre-collected prompt index and is also selectable for prompts you define yourself, so it is covered on both tracking paths.](https://ahrefs.com/brand-radar)
- [Perplexity: yes — Perplexity is named in the index platform list and in the custom-prompt platform list, so both the instant database and self-defined prompt tracking cover it.](https://ahrefs.com/brand-radar)

**Trade-offs against SerpApi:**
- None found.

### 2. Rankshift

Credit-metered AI visibility, citation and crawler tracking with unlimited projects and seats.

**Where it improves on SerpApi:**
- [Monitors AI answers: yes — Core purpose: it runs your prompts on a schedule across the major answer engines and records whether each answer mentions or cites the brand, rather than relying on manual spot checks.](https://www.rankshift.ai/ai-visibility-tracking/)
- [ChatGPT: yes — ChatGPT heads the vendor's engine inventory and the credit calculator prices a ChatGPT run at two credits, so it is available on every self-serve plan.](https://www.rankshift.ai/ai-visibility-tracking/)
- [Perplexity: yes — Perplexity is named in the engine inventory on both the visibility and citation pages and costs two credits per run in the published calculator.](https://www.rankshift.ai/ai-citation-tracking/)

**Trade-offs against SerpApi:**
- None found.

### 3. Promptwatch

AI search visibility tracking with crawler logs and content agents that publish to your CMS.

**Where it improves on SerpApi:**
- [Monitors AI answers: yes — Core purpose of the product: prompts are re-run against the answer engines and the brand's mentions, visibility score and share of voice are recorded from real LLM interfaces rather than APIs.](https://promptwatch.com/)
- [ChatGPT: yes — ChatGPT is listed as a supported model on every published plan column and is the one model the non-paid entry tier is limited to, so coverage starts at the bottom of the ladder.](https://promptwatch.com/docs/academy/choosing-your-models)
- [Perplexity: yes — Perplexity appears as a supported AI model in the plan comparison table with a tick on Essential, Professional and Business, and is grouped with the live-search platforms that return citations.](https://promptwatch.com/docs/academy/choosing-your-models)

**Trade-offs against SerpApi:**
- None found.

**Trade-offs against SerpApi:**
- [MCP server: no — The published programmatic surface is a bearer-token REST API plus a JavaScript SDK; no MCP server is documented on the API reference or anywhere else on the site.](https://llmrefs.com/ai-seo-api)
