Otterly vs Semrush

Otterly monitors AI search on four base engines with audits and recommendations: mentions, sentiment, citations, a crawlability checker and prompt research. Semrush, an Adobe company, is a nine-toolkit suite spanning SEO, content, local, social and advertising, with an AI visibility module tracking five engines, metered by prompts per tier. They compete only where the categories overlap, and the chapters below walk every dimension a buyer would price: which AI engines each can see, how the tracking actually meters, what each produces on the content side, what surrounds the core product, and the full published tier lists.

Otterly is an AI search monitoring tool with real credentials: a Gartner Cool Vendor for AI in Marketing in 2025, a 4.8 rating badge, and 30,000+ marketing professionals by its own count, with Roche, Opera and BenQ among the logos on its pricing page. The surface covers brand mentions, sentiment and citations tracked daily, a Brand Visibility Index, domain citation tracking updated weekly, AI prompt research, a crawlability checker, content audits with specific improvement recommendations, and ChatGPT Ads and Shopping tracking.

Pricing model. Lite $29, Standard $189 and Premium $489 a month with 15% off annually and four engines included on every tier; Claude costs $29 to $439 a month extra by tier, Gemini and Google AI Mode $9 to $149 each, and Enterprise starts from $1,000 a month.

Semrush, now an Adobe company, is the biggest suite in search marketing, with homepage scale stats of 28 billion keywords, 43 trillion backlinks, 808 million domain profiles, 142 geo databases and 289M+ LLM prompts. Nine toolkits share one login across SEO, traffic analytics, content, local, social, advertising and PR, and the AI visibility module tracks how often your brand appears in answers from ChatGPT, Perplexity, Gemini, Claude and AI Overviews, with sentiment and custom prompt monitoring from the entry SEO plan.

Pricing model. SEO $139, Starter $199, Pro+ $299 and Advanced $549 a month billed monthly, with annual billing saving up to 17% ($117.33 to $455.67); AI prompt tracking is metered at 50, 100 and 200 prompts daily by tier, and a free $0 plan offers one demo project.

Otterly. Four engines are included on every tier, verbatim from the pricing cards: ChatGPT, Google AI Overviews, Perplexity and MS Copilot. Claude, Google AI Mode and Gemini are sold as add-ons, with Claude at $29, $109 or $439 a month by tier and Gemini and AI Mode at $9, $59 or $149 each; Grok and DeepSeek appear on neither list.

Semrush. The features page publishes the engine list: ChatGPT, Perplexity, Gemini, Claude and AI Overviews, making Semrush one of the few big suites with Claude included. Grok, DeepSeek and Google AI Mode do not appear in that list.

Summarized: Otterly reads 4 included (ChatGPT, AIO, Perplexity, Copilot); Claude, Gemini, AI Mode as add-ons; Semrush reads 5: ChatGPT, Perplexity, Gemini, Claude, AI Overviews. On Claude specifically, Otterly: add-on, $29 to $439/mo; Semrush: yes.

Otterly. Prompt runs are daily on every tier, 15 prompts on Lite up to 400 on Premium, with extra prompts at $99 per 100 on the upper tiers. Domain Citation Tracking refreshes weekly per the features page, and sentiment classification tags mentions as enthusiastic, with caveats, or dismissed.

Semrush. AI prompt tracking meters by tier: 50 prompts daily on Starter, 100 on Pro+, 200 on Advanced, alongside classic position tracking with 500 to 5,000 keywords and 5 to 40 monitored websites. AI brand sentiment and AI visibility reports for any domain ship from the $139 SEO plan.

Otterly. The optimization surface is audit and advice: a content audit that produces specific improvements, a crawlability checker, prompt research and recommendations. There is no long-form writer and no CMS publishing anywhere on the public pages, so the output is a to-do list for your team.

Semrush. The content toolkit generates full-length, SEO-ready articles from a brief, with AI features woven through Domain Overview and Keyword Suggestions. CMS publishing targets are not enumerated on the pricing or features pages, so where the generated article lands is a question for their sales team.

Otterly. There is no Google organic rank tracker and no local surface of any kind on the public pages; the product's scope is AI search.

Semrush. Classic SEO is the suite's backbone: position tracking, a technical site audit crawler, the 28B-keyword research database and the 43T-link backlink index. A local toolkit with listing management and map rank tracking exists; whether it draws a geo-grid or covers Apple Maps is not stated on the rendered pages.

Otterly. API and MCP access ship from the $189 Standard tier, metered at 2,000 requests a month each (5,000 on Premium), with a Google Looker Studio connector on the same tiers and CSV exports on every tier.

Semrush. MCP access lists from the $199 Starter tier and API data integration only on the $549 Advanced tier. White-labeling arrives through the Pro Report add-on at $20 a month, and the suite's own research database is the underlying asset most buyers pay for.
