OtterlyAI vs Semrush: 2026 Comparison

Published October 29, 2026

OtterlyAI is a low-priced AI search tracker that starts at $29 for 15 prompts, and the Semrush AI Visibility Toolkit is the AI search add-on to a broader marketing suite that starts at $99 for 25. The entry prices point to OtterlyAI, but its Standard plan costs $189 for 100 prompts, so the gap depends on how many prompts a team tracks and how many engines each prompt runs on.

Our analysts compared each vendor's pricing pages and help documentation as of October 29, 2026, then priced three one-brand workloads of 25, 100, and 350 prompts tracked daily. 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 plan plus add-ons, that covers the job with daily tracking. Semrush is shown on one engine and on three engines.

OtterlyAI vs Semrush Cost for the Same Workload

Semrush assigns each tracked prompt to one engine, while OtterlyAI runs each prompt on several engines, so the Top GEO Agencies research team priced the same jobs with each tool's own counting. Each workload is tracked daily:

  • One brand with 25 prompts.
  • One brand with 100 prompts.
  • One brand with 350 prompts.

Each cost is the cheapest published plan, or plan plus add-ons, that covers the workload. Semrush appears on one engine, and on three engines where each engine uses its own prompt allowance.

OtterlyAI vs Semrush Monthly Cost by Workload, October 2026

WorkloadOtterlyAISemrush AI Visibility Toolkit
1 brand, 25 prompts$189 (Standard, because Lite stops at 15 prompts)$99 on one engine ($99 plan); $159 on three engines ($99 + 1 add-on)

1 brand, 350 prompts$489 (Premium, 400 prompts)$519 on one engine ($99 + 7 add-ons); $1,359 on three engines ($99 + 21 add-ons)
  • OtterlyAI's Lite plan stops at 15 prompts, so 25 prompts need Standard at $189. Standard covers 100 prompts, and Premium covers up to 400.
  • Semrush's base plan includes 25 prompts, and each add-on gives 50 more for $60 per month. 100 prompts need 2 add-ons ($99 + $120 = $219), and 350 prompts need 7 ($99 + $420 = $519).
  • On three engines, Semrush counts 75, 300, and 1,050 prompts of allowance, which need 1, 6, and 21 add-ons and cost $159, $459, and $1,359. OtterlyAI's four included engines run on each prompt at no extra prompt cost.
  • Semrush One Starter, Pro+, and Advanced list 50, 100, and 200 prompts. We did not price them because their plan prices did not load in our October 29 capture.

OtterlyAI or Semrush: Which Fits Which Buyer

The cheaper tool changes with the length of the prompt list and the number of engines a team wants each prompt run on.

Choose OtterlyAI if

  • You track 100 to 400 prompts for one brand. Standard costs $189 for 100 prompts and Premium costs $489 for 400, against $219 and $519 on Semrush with one engine per prompt.
  • You want four engines on every plan: ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot are included, while Semrush needs extra prompts for each engine.
  • You want unlimited team seats and workspaces. Semrush charges $99 per month for each extra user.
  • You want a 7-day trial with 50 prompts and no credit card. The Semrush toolkit has no free trial.

Choose Semrush AI Visibility Toolkit if

  • You track 15 to 25 prompts on one engine. Semrush costs $99, while OtterlyAI's Standard plan costs $189 once a list outgrows Lite's 15 prompts.
  • You already pay for Semrush or want SEO and AI visibility in one Semrush One subscription.
  • You want topic-level prompt research with volume, difficulty, and intent, and the Claude connector for Semrush One subscribers.
  • You want Prompt Tracking in more than 220 countries and territories, with PDF and CSV exports.

Data Collection and Methodology

Prices and plan details come from each vendor's pricing and help pages as of October 29, 2026. Changelog and press release dates in the recent changes list come from pages captured October 28 and 29, 2026. All prices are list prices in US dollars per month before tax, billed monthly unless the row says otherwise. Semrush's pricing page lists $99 per domain per month billed annually, while its help page lists $99 per month, so the monthly-billing price may differ. A "prompt" is one question the tool asks the AI engines. OtterlyAI Enterprise is quoted privately. OtterlyAI's help center lists the Standard and Premium annual prices, which we did not use in the workloads. Agent Analytics, audit, and API limits come from the pricing page and the help center.

Semrush Enterprise is quoted privately, and the Semrush One bundle prices did not load in our capture, so neither appears in the cost table. Semrush assigns each Prompt Tracking campaign to one engine and does not state how it counts one prompt run on several engines, so we show the one-engine cost and a three-engine cost that treats each engine as its own prompt allowance. We calculated products, differences, and ratios from the published values.

Semrush publishes one AI Visibility Toolkit plan at $99 per domain, prompt add-ons at $60 per 50 prompts, and extra users, domains, or locations at $99 each. OtterlyAI publishes its own tiers, listed in the matrix above.
