Otterly vs Surfer

Otterly monitors AI search on four base engines with audits and recommendations: mentions, sentiment, citations, a crawlability checker and prompt research. Surfer is a content optimization platform: its Content Editor scores drafts live against the pages ranking on Google, with an AI Tracker across five engines and Surfer AI drafting. 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.

Surfer built the live draft-scoring category: the Content Editor grades a draft in real time against the pages already ranking on Google for a keyword, with term recommendations and structural targets as you type, and it remains the deepest tool of its kind. Around the editor sit Surfer AI drafting, a plagiarism checker, one-click internal linking, content ideas and coverage gap analysis, cannibalization reports, and an AI Tracker following brand visibility across five engines.

Pricing model. Discovery $49, Standard $99, Pro $182 and Peace of Mind $299 a month, all billed yearly, plus a $999-a-month Enterprise plan; AI tracking starts on Standard with 25 prompts refreshed weekly, and daily refresh starts on Pro at $182.

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.

Surfer. The AI Tracker's compare table lists five engines: ChatGPT, Perplexity, Google AI Mode, Google AI Overview and Google Gemini. Claude, Grok and DeepSeek appear nowhere on the pricing page, which invites you to email them to request another model.

Summarized: Otterly reads 4 included (ChatGPT, AIO, Perplexity, Copilot); Claude, Gemini, AI Mode as add-ons; Surfer reads 5: ChatGPT, Perplexity, AI Mode, AI Overviews, Gemini. On Claude specifically, Otterly: add-on, $29 to $439/mo; Surfer: no.

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.

Surfer. Prompt tracking meters by tier and cadence: 25 prompts refreshed weekly on the $99 Standard plan, 50 refreshed daily on Pro, 100 daily on Peace of Mind, with Mention Gap and Brand Sentiments included. Classic rank tracking is one thing Surfer does not do; its measurement of Google is SERP analysis for scoring, with rank drop detection on documents.

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.

Surfer. This is the flagship: live scoring against the SERP while a human writes, Surfer AI full drafts, content optimization, templates and custom voices from the Pro tier, and 360 documents a month on the mid tiers rising to unlimited on Peace of Mind. Integrations for publishing cover WordPress, Google Docs, Contentful and Zapier; Shopify is not listed.

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.

Surfer. There is no local surface: no Google Maps tracking, no geo-grid, no GBP monitoring, no citations anywhere in the product.

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.

Surfer. API access appears in the Peace of Mind ($299) feature list, and no MCP server appears anywhere on the pricing page or homepage; earlier checks of their API docs show access running through API keys and third-party connectors.
