1. 1

   Jasper

   On-brand campaigns across blog, social, and ads

   Jasper leads this page because content marketing is brand voice across more than one format. The agent and knowledge features match that job better than a single SEO editor. You still need a search tool if the page has to rank.

   料金

   From $69/mo

   Pro is $69/seat/month, or $59/seat/month billed annually. A 7-day Pro trial requires a card. No ongoing free plan. Business is custom. Read from Jasper's public pricing discussion and plan cards; confirm on jasper.ai/pricing.

   主な機能

   Surfer, HubSpot, Webflow, Google Docs. Agents and Canvas can carry a draft through a workflow. A marketer still approves anything that publishes.

2. 2

   Frase

   A content loop that can file the draft

   Frase researches, drafts, and can push to WordPress, Webflow, Sanity, or Wix. The $39 yearly starter price is real. Publishing is a switch, not the default you should leave on.

   料金

   From $39/mo billed yearly

   frase.io/pricing lists Starter at $39/mo billed yearly ($49 month to month), Professional at $103/mo billed yearly ($129 month to month), and Scale at $239/mo billed yearly ($299 month to month). Enterprise is custom. A 7-day trial needs no credit card. Last checked 5 October 2026.

   主な機能

   WordPress, Webflow, Sanity, Wix. The agent can publish when you allow it. Approval is the default for Content Guard fixes.

   Copy.ai

   Workflow-shaped content once you leave chat

   Copy.ai scores well on autonomy because the workflow product can carry a content motion, not just a paragraph. Remember the price cliff: Chat is $29, workflows start at $1,000. The rank is for the workflow product.

   料金

   From $29/mo

   Chat is $29/mo ($24/mo billed annually) with 5 seats and no workflow credits. Growth is $1,000/mo with workflow credits. There is no free plan for the platform. Confirmed against Copy.ai's public prices page.

   主な機能

   Salesforce, HubSpot, Slack. Workflows can run multi-step sales and marketing jobs. Chat alone is a copilot. The interesting autonomy starts on the workflow plans.

5. 5

   Surfer

   Search-led articles

   Surfer is the right row when the content is a page that has to earn a query. It is the wrong row for campaign creative, sales enablement, or social. The SEO page ranks it first; this page does not.

   料金

   From $49/mo

   Discovery is $49/mo. Standard is listed at $99/mo and higher tiers run well above that, with annual billing discounts on the public pricing page. No permanent free plan. Checked on surferseo.com/pricing on 5 October 2026.

   主な機能

   Google Docs, WordPress, Jasper. Surfy drafts and the editor nags you toward a content score. A person still chooses the page, the angle, and the publish button.

   利用者の声

   Trustpilotで何年もSurferを使う人は、コンテンツエディタが隙間と意味的なキーワードを、当てずっぽうなしで示す、と書いています。

   別のレビューは、やっていることに対して値段が高く、解約後にカードを外せない、と書いています。

   • “We’ve been using Surfer for quite some time, and it’s been a really solid tool for SEO content optimisation. The Content Editor is the standout, it makes it much easier to structure content, identify gaps, and optimise without guessing.”

     Trustpilot

   • “I have been using SurferSEO for 3 years now, and I really enjoy how it allows me to set up an article with new semantic keywords to broaden my content.”

     Trustpilot

   • “When it comes to their product, sure, it's a decent piece of software, but not better thn cheaper alternatives.”

     Trustpilot

   • “Worst ans unsecure service. There is no option to remove credit card from Surferseo website.”

   HubSpot Breeze

   Content tied to the CRM

   Breeze's content agent matters when the draft has to know who the contact is. It ties Surfer on the total and loses the tie-break on job fit, because a CRM content agent is not a content studio.

   料金

   Free CRM, hubs from $15/seat/mo

   Free CRM includes the Breeze assistant. Marketing Hub Starter is $15/seat/month billed monthly or $9/seat/month billed annually. Professional is a different budget (about $800/mo annual, plus onboarding). Prospecting and customer agents consume credits. Confirm on hubspot.com/pricing.

   主な機能

   HubSpot CRM, Gmail, Slack, Salesforce. The assistant is a copilot. Prospecting and customer agents can carry a task and should still stop for a person on anything customer-facing.

   Clearscope

   Optimizing a draft a writer already owns

   Clearscope is the editor's tool, not the campaign system. Essentials is $129/mo. Pair it with Jasper or Frase if you also need the first draft.

   料金

   From $129/mo

   clearscope.io/pricing lists Essentials at $129/month, Business at $399/month, and Enterprise as custom. The page offers a 14-day free trial and says monthly plans have no minimum contract. Last checked 5 October 2026.

   主な機能

   ChatGPT, Gemini. It recommends and drafts. A person still publishes.

8. 8

   Semrush

   Topic research before anyone writes

   Partial fit. Semrush tells you what to write. It is not the writing agent. Keep it in the stack and off the top of this list.

   料金

   From $139.95/mo

   A limited free account exists. Pro is $139.95/mo on monthly billing, with a lower annual rate. Guru and Business step up from there. Paid plans offer a 7-day trial. Confirm on semrush.com/pricing.

   主な機能

   Google Search Console, Google Analytics, Looker Studio. AI features draft and summarize inside a suite a person drives. Semrush does not run your SEO program.
