Promptwatch vs Ahrefs Brand Radar: 2026 Comparison

Published November 2, 2026

Promptwatch and Ahrefs Brand Radar both sell self-serve AI search tracking, and Brand Radar's $50 entry package undercuts Promptwatch's $95 Essential plan. The tools bill differently, since Promptwatch sells three plan tiers with prompt, seat, and response limits and tracks every model it supports, while Brand Radar bills in checks, one prompt on one engine in one location, with overage rates that fall as packages grow. The cheaper tool depends on how many prompts a team tracks and whether it values Promptwatch's built-in content agents.

Our analysts compared each vendor's pricing pages, changelogs, and product pages as of November 2, 2026, then priced three common tracking workloads on each. In the following sections, we compare the two tools on the points buyers weigh most, price the same work on both, and explain which buyer each fits and what changed recently.

List prices in US dollars before tax, billed monthly unless the row says otherwise. Workload costs are the cheapest published plan, or package plus overage, that covers the job with daily tracking.

Promptwatch vs Ahrefs Brand Radar Cost for the Same Workload

Promptwatch sells plan tiers and Ahrefs bills custom prompts in checks, so the Top GEO Agencies research team priced the same tracking jobs on both. Each workload is tracked daily:

  • One brand with 25 prompts on ChatGPT, Google AI Overviews, and Perplexity, three engines both vendors cover.
  • One brand with 100 prompts on those three engines.
  • One brand with 300 prompts on those three engines.

Each cost is the cheapest published plan, or plan plus overage, that covers the workload.

  • Ahrefs counts 1 check for each prompt on each platform per run. 25 prompts on 3 engines for 30 days are 2,250 checks, inside Basic's 2,500. 100 prompts are 9,000 checks, which cost $100 plus 2,000 checks of overage at $0.015 on Growth. 300 prompts are 27,000 checks, which cost $250 plus 2,000 checks of overage at $0.010 on Scale.
  • Promptwatch's prompt limits set the plan: Essential covers 50 prompts, Professional 150, and Business 350. Each workload also fits inside the plan's response allowance of 6,000, 18,000, and 42,000 responses.

Promptwatch or Ahrefs Brand Radar: Which Fits Which Buyer

Ahrefs Brand Radar: As of November 2, 2026, Ahrefs' pricing page cites more than 525 million prompts, up from 519 million on its October 30 page, and labels Bot Analytics and its YouTube, TikTok, and Reddit search as free while in beta.

Promptwatch ships weekly, and Ahrefs labels its beta tools free for now.

Data Collection and Methodology

Prices and plan details come from each vendor's pricing, changelog, and product pages as of November 2, 2026, except where a source line shows another capture date. All prices are list prices in US dollars per month before tax, billed monthly unless the row says otherwise. A "prompt" is one question the tool asks the AI engines. Ahrefs bills its own prompts in "checks," where one prompt run once on one platform in one location is one check.

Promptwatch Enterprise prices are quoted privately, so none appears in the cost table. Promptwatch's pricing page does not say how many responses one prompt uses per run, so we assumed one response per prompt per engine per daily run, which is 90 per prompt per month on three engines.

We calculated products, differences, and ratios from the published values.

Promptwatch publishes three self-serve plans and a custom tier above them. Ahrefs publishes three custom prompt packages, database access from $199 per month, and four Ahrefs plans with prompts included.

Ahrefs' pricing page shows no Brand Radar seat terms, so the matrix lists them as not published. Engine lists and Claude check rates for Ahrefs are from its Brand Radar page.
