AI Brand Watch — monitor your brand's visibility in ChatGPT, Claude, Perplexity & Gemini

Know the day AI stops recommending you. 80% of what AI engines say about your brand never shows up in your analytics. AI Brand Watch asks the questions that define your category to ChatGPT, Claude, Perplexity and Gemini — on a schedule — and tells you what changed: share-of-voice diffs and signed webhooks, not dashboards.

by Desvela — your agent sleeps, Desvela doesn't.

How it works

1. Tell it your battlefield. Your brand (+aliases), your competitors, and the 5-30 questions buyers ask AI in your category ("best CRM for small business in Spain").
2. It samples the engines. AI answers vary between runs, so each question is asked N times per engine. You get share of voice — the % of answers that mention you — plus your average position and which sources each engine cites.
3. You only hear about changes. A signed webhook (or the dataset) fires when you appear, disappear, shift ≥25 points, or the engine starts citing a new source or competitor. Schedule it weekly with Apify Schedules and forget it.

Every run also emits a visibilityScore (0–100) summary — one comparable number per brand, built from share of voice (55%), mention position (15%), engine coverage (15%) and citations of your own URL (15%). Track it weekly; screenshot it for your boss.

Pricing (pay per check, no subscription)

Event	Price
Actor start	$0.02
Brand query checked (per query × engine, includes all samples)	$0.08
GEO recommendations (opt-in add-on, per run)	$0.04
Change alerts	free

Typical setup — 20 queries × 2 engines, weekly: ≈ $14/month — SaaS equivalents charge $29–$99+/month for the same signal (Semrush AI Visibility from $99/mo, Otterly from $29/mo). If you're looking for an Otterly, Peec, Profound or Semrush AI Visibility alternative without the subscription, this is it. The free Apify plan credits cover a full trial run.

Agents can pay for this themselves (x402)

This Actor accepts agentic payments over x402: an AI agent can run it paying USDC on Base, with no Apify account, no billing setup and no API key. Calling it without credentials returns 402 Payment Required with the payment terms attached, which is exactly what an x402 client expects:

curl -i -X POST https://api.apify.com/v2/acts/desvela~brand-watch/runs \
  -H 'Content-Type: application/json' -d '{}'
# HTTP/2 402 · {"error":{"type":"x402-payment-required", ...}}

Practical note: Apify's agentic flow buys a prepaid, spend-capped token with a $1 minimum, valid 14 days, and unused balance is not refunded. At $0.08 per query·engine that first dollar covers roughly a dozen checks, so it is worth spending it rather than topping up per run.

Not every Actor is eligible (it requires pay-per-event pricing, limited permissions and no Standby mode). This one is, and no opt-in is needed on your side.

Real numbers from our own brands

Before charging anyone we ran Brand Watch on two businesses we own (full disclosure — that's why we can show the raw numbers):

• A digital time-capsule product: 0% share of voice across all four engines — completely invisible. But the run returned the exact sources the engines cite instead (YouTube dominates; Arweave, IPFS and OpenTimestamps own the category). That list is the GEO to-do list — one run, ~$5.
• A photography backdrop store: brand mentions 0%, yet its URL is cited by Perplexity in 4 of 5 queries. Brand mention and source citation are different metrics — we measure both. Each engine cites a different source ecosystem (Gemini favors photo blogs; Perplexity cites the store and Reddit).
• On the purchase-intent query ("where to buy…") the store appeared in 1 of 3 samples. A single check would have called that yes or no at random; sampling turns it into a rate worth tracking — the weekly watch now guards exactly that number.

Honest measurement notes

• We call the engines' APIs with web search enabled. API answers correlate with, but are not pixel-identical to, each consumer product. We always measure the same way, so diffs are valid.
• Share of voice over N samples is the metric — single snapshots of a non-deterministic system are noise, and we refuse to sell you noise.

FAQ

Which engines? OpenAI (ChatGPT), Perplexity, Anthropic (Claude), Gemini. Pick any subset. Do I need my own API keys? No — checks run on ours; the per-check price includes it. Can my AI agent consume this? Yes — that's the point. Webhook + dataset are structured for machines, and the actor is callable as an MCP tool today via the Apify gateway: https://mcp.apify.com/?tools=desvela/brand-watch (works from Claude, Cursor or any MCP client — docs at desvela.dev).
