- Semrush also sells newer SEO and AI Search bundles, with the SEO bundle at 139 dollars per month and AI visibility tracking included.
- A limited free plan is available, with a 7 day free trial on subscription plans.
- The breadth is also the drawback.
- Pro includes one user seat, and extra seats cost from 45 dollars per month.
Pros
- Covers keyword research, audits, incoming links and PPC in one login
- AI visibility tracking on newer bundles
Cons
- Pro excludes the Content Marketing Toolkit, so content briefs need a higher tier or an add-on
Ahrefs
Best for: Link research and rank tracking
Ahrefs Lite costs 129 dollars per month on monthly billing, or 107.50 dollars per month on annual billing. Lite includes 5 non-verified projects, 750 tracked keywords, 100,000 crawl credits and 150 AI prompt checks per month.

- Ahrefs also sells Brand Radar as an add-on from 199 dollars per month for AI visibility work.
- The rank tracker updates weekly on every plan.
- The main limit is the credit system.

- API and MCP access from Lite
Cons
- Lite includes only 1,000 credits per user per month and 6 months of history
Surfer SEO
Best for: On-page content optimisation
Surfer SEO, now called Surfer, is an on-page optimisation tool. The Content Editor scores a draft against top-ranking pages for structure, terms and length, and it guides writers while they work. Discovery costs 49 dollars per month on annual billing, or 59 dollars on monthly billing, and includes 120 documents and 1 seat.
- Standard costs 99 dollars per month on annual billing, with 360 documents, 50 pages and 3 seats.
- Pro costs 182 dollars per month on annual billing, with 5 seats and 200 pages.
- The entry plan is a real starting point, but it has limits.
- Discovery has no tracked AI prompts, and AI Search Analytics is a separate plan at 82 dollars per month on annual billing.
Pros
- Content Editor scores drafts against live search results
- clear plan limits
Cons
- No free plan, and internal linking and custom voices sit on Pro at 182 dollars per month on annual billing
Frase
Best for: AI briefs and content optimisation
Frase builds content briefs from search results, then offers an editor that scores a draft as you write. The current plans are Starter at 39 dollars per month on annual billing, or 49 dollars on monthly billing, Professional at 103 dollars per month on annual billing, and Scale at 239 dollars per month on annual billing. Starter includes 10 articles, 50 audit pages, 1 seat and 1 site.
- Professional expands to 3 seats and 5 sites.

- The limit is volume.
- Starter covers 10 articles per month, so a team that publishes more than that must move up or buy add-ons.
Pros
- SERP-based briefs and an AI writer in one tool
- low entry price
Cons
- Starter includes only 10 articles per month, and the SEO add-on costs extra on some plans
Clearscope
Best for: Editor-grade content grading
Clearscope grades a page against top-ranking content and gives writers a clear list of terms and topics to cover. Essentials costs 129 dollars per month, with 50 tracked queries, 50 pages, 20 topic explorations and 20 drafts per month. Business costs 399 dollars per month, with 300 tracked queries and 300 pages.

- There is no minimum contract on monthly plans.
- The price is the main drawback.
Pros

SE Ranking
Best for: Low cost all-in-one SEO
SE Ranking is an all-in-one SEO platform with keyword research, rank tracking, site audit, link monitoring and a content editor. The current plans are Core at 129 dollars per month, or 103.20 dollars per month on annual billing, Growth at 279 dollars per month, or 223.20 dollars on annual billing, and Enterprise at a custom price. Core covers 10 projects, 1 seat and 2,000 keywords tracked daily.
- A 14 day free trial is available.
- The old Essential, Pro and Business plans were retired in late 2025, so guides that quote 52 dollars per month are out of date.
- The main watch-out is add-ons.
- AI visibility tracking, local marketing and content marketing are sold separately, and stacking them can close the price gap with Semrush.
Pros
- Daily rank tracking and a content editor in the base plan
- lower cost than Semrush and Ahrefs
Cons
- AI visibility tracking is an add-on, and the old Essential, Pro and Business plans are retired
MarketMuse
Best for: Content strategy and topical authority
MarketMuse is a content intelligence platform for strategy, not just single-page optimisation. It maps a site topical authority, finds content gaps, and builds briefs from that map. The platform offers a free tier with 10 queries per month, which is enough to test the interface but not enough to plan a content program.
- Standard plans were listed at 149 dollars per month in older guides, but MarketMuse now uses quote-based pricing for many tiers after its acquisition,
- The credit model is the main cost risk.
- Content briefs require credits on the Standard plan, with older guides listing 25 dollars per brief, and unlimited briefs only on higher tiers.
- A team that runs 20 briefs per month could add a large sum on top of the base fee.
Pros
- Models topical authority across a whole domain before it plans content
- strong briefs
Cons
- No published price, and briefs use credits that can add cost on top of the base plan
How we chose
We compared pricing pages, product pages and plan documentation for each vendor, and we checked the prices on 12 November 2026. We favoured tools with a clear AI feature, such as AI briefs, AI drafting, AI prompt checks or AI visibility tracking, plus a published price or a clear quote-only model. We did not claim hands-on testing, and we did not use third-party review scores to rank the tools. Where a vendor changed its plan names, such as SE Ranking in late 2025 or Surfer in 2026, we used the current plan names and noted the change, so readers do not chase a retired tier.
How to choose by budget and volume
| Monthly budget | Content volume | Best starting point | | Under 50 dollars | Up to 10 articles a month | Frase Starter at 39 dollars, or Surfer Discovery at 49 dollars | | 50 to 130 dollars | Up to 30 articles a month | SE Ranking Core at 103.20 dollars, or Ahrefs Lite at 107.50 dollars | | 130 to 200 dollars | Full SEO plus content | Semrush Pro at 117.33 dollars, or Clearscope Essentials at 129 dollars | | Over 200 dollars | Large content program | Surfer Pro, Clearscope Business, or MarketMuse by quote | | Quote only | Domain strategy | MarketMuse, with a written quote for briefs and queries |
Frequently asked questions
What is the best AI SEO software?
The best tool depends on the job. Semrush suits teams that want a full suite with AI visibility, Ahrefs suits teams that put link research first, and Surfer suits editors who want on-page optimisation. Frase suits small teams that want briefs and AI writing in one tool, while Clearscope suits editorial teams that want a clear grade for each page.
How much does AI SEO software cost?
Entry prices in this list run from 39 dollars per month for Frase Starter to 139.95 dollars per month for Semrush Pro on monthly billing. Annual billing lowers the monthly rate on most tools, such as Semrush Pro at 117.33 dollars and Ahrefs Lite at 107.50 dollars. Add-ons for AI visibility, extra seats and extra credits can lift the bill, so check those lines before you buy.
Is Surfer SEO better than Clearscope?
Surfer starts lower, at 49 dollars per month for Discovery, and it includes keyword research and AI drafting. Clearscope starts at 129 dollars per month, but it includes unlimited users and a simpler grading view. Surfer suits editors who want a broad tool at a lower price, while Clearscope suits editorial teams that want a clean grade and draft workflow for single pages.
Do these tools write articles for me?
Most of them help with drafting, but they do not replace an editor. Surfer, Frase and Some tools can draft from a brief, and Clearscope can draft a page from a direction you set. The output still needs fact checking, editing and a human voice, because AI drafts can miss search intent, repeat common claims and use terms that do not fit your brand.
What is AI visibility tracking?
AI visibility tracking shows how often a brand or page appears in AI answers, such as ChatGPT, Gemini and Google AI Overviews. Semrush sells it as part of its newer bundles, Surfer sells it as a separate plan, and Ahrefs sells Brand Radar as an add-on. It is a newer feature, so check the prompt count, the engines covered and whether the data updates daily or weekly.
Can I use a free plan to test AI SEO software?
Yes, on some tools. Semrush offers a limited free plan, Frase offers a free version with 1 document, and MarketMuse offers a free tier with 10 queries per month. Clearscope and SE Ranking offer a 14 day free trial instead of a free plan. Use the trial to test the exact workflow you need, such as briefs, grading or rank tracking, rather than the demo data.
