Best LLM SEO Analysis Software in 2026: 9 Tools Compared

Surfer SEO analyzes the pages ranking for your target keyword and scores your draft against them in real time, covering terms, structure, length, and headings. The Essential plan costs 79 dollars per month billed annually and includes content tracking, keyword research, and AI article generation limits, with a 7-day money-back guarantee. Integrations with Google Docs and WordPress keep the score inside the editor where writers work.

The gap is AI visibility. Surfer tells you how a page should perform in classic search, not how ChatGPT answers questions in your category. For a content team whose traffic still comes mostly from Google, Surfer remains our pick. Teams that also need answer-engine tracking should pair it with a dedicated tracker below.

Clearscope grades content with a letter from A to F, based on terms found in top-ranking pages and analyzed with natural language processing. The Essentials plan costs 189 dollars per month and includes content inventory pages, keyword discovery, and monthly content reports, with unlimited users, which softens the price for larger editorial teams. Its Google Docs integration means writers optimize without learning a new editor.

The price is the obvious hurdle for a solo creator, and Clearscope does not track AI answer engines. It suits publishers and agencies where editors need one trusted grade and where the cost spreads across many writers. Smaller teams will get similar scoring from Surfer or Frase for less.

Frase excels at the first step of content work: research and briefs. It pulls the structure, headings, and questions from top-ranking pages and turns them into a brief a writer can follow in minutes, then offers an AI writer for drafting. The Basic plan costs 45 dollars per month, with a free trial, making it the friendliest entry point among the content optimizers on this list.

Scoring is less deep than Surfer's, and Frase does not monitor AI answer engines. For freelancers and small teams whose main bottleneck is turning research into briefs, Frase is the best value. Teams that live by content scores should weigh Surfer instead.

MarketMuse works above the individual page. It inventories your content, scores your authority on topics, finds gaps against competitors, and produces briefs for the pieces that will move authority most. The Standard plan costs 149 dollars per month, and a free tier covers limited queries, which is enough to test the inventory view.

It is not a writing editor, so teams still need Surfer, Frase, or Clearscope for page-level optimization. MarketMuse fits publishers and enterprises planning dozens of pieces a month around topic clusters. A small blog with a handful of posts will not use enough of it to justify the price.

Profound is the enterprise name in AI visibility. It tracks how answer engines mention your brand, which pages they cite, and what people actually ask in your category, across up to 9 engines on enterprise plans, including ChatGPT, Perplexity, Google AI Mode, Gemini, and Claude. A free trial covers a limited set of prompts on ChatGPT, and agencies get self-serve workspaces per client.

The catch is pricing transparency. After the trial, brand pricing is custom enterprise, so a small business cannot simply sign up at a listed rate. For a brand treating AI search as a real channel with budget to match, Profound's depth is unmatched. For a startup, Otterly or Peec AI will cover the basics at a published price.

Peec AI tracks brand visibility, position, and sentiment across AI engines, with prompt-level history and competitor comparisons. Agencies like its white-label dashboards and client reporting, plus multi-market tracking for brands operating in several countries. Plans are tiered by prompt volume, with a Pro tier covering 150 prompts and an Advanced tier covering 350.

Pricing is the confusing part, since published figures differ across sources and regions, so check the vendor's own pricing page for your market before budgeting. For an agency managing AI visibility for several clients, Peec AI's reporting and seat model make it a strong middle option between Otterly and Profound.

Otterly.AI is the cheapest way to start tracking AI visibility seriously. The Lite plan costs 29 dollars per month and covers 15 prompts across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot, with unlimited workspaces. Higher tiers raise prompt counts to 100 on Standard at 189 dollars per month and 400 on Premium at 489 dollars per month.

The entry tier's prompt limit is tight for a brand with many products, and Claude, Google AI Mode, and Gemini coverage costs extra. Still, for a small team taking its first look at how AI answers describe it, Otterly gives real data at a price that needs no procurement meeting.

Scrunch AI goes beyond monitoring. Its Core plan costs 250 dollars per month and tracks prompts, citations, and brand presence across ChatGPT, Perplexity, Google AI Overviews, and Copilot, with enterprise plans adding Claude, Gemini, Meta AI, Google AI Mode, and Grok. Its Agent Experience Platform also serves an AI-optimized version of your site to crawlers, aiming to fix what models get wrong rather than only reporting it.

That ambition comes at a price that rules out small blogs, and the deepest features sit behind enterprise quotes. For a mid-size brand that wants monitoring plus a way to act on it, Scrunch is the most complete single purchase on this list.

Semrush is the all-in-one platform that many teams already pay for, covering keyword research, site audits, backlink analysis, and rank tracking. The Pro plan starts at 139 dollars per month, with a limited free tier, and an AI visibility toolkit is available as a paid add-on for teams that want answer-engine tracking tied to their existing SEO data.

The add-on pricing means AI visibility is not included in the base plan, and the sheer breadth of Semrush can overwhelm a new user. If your team already lives in Semrush, adding its AI toolkit is cheaper and simpler than buying a separate tracker. If you only need AI visibility, a focused tool like Otterly will be simpler.
