The Chat plan is a published $29 entry for unlimited chat and no workflow credits. The next step, Growth, is $1,000 a month and is where automated workflows actually live. Judge it on the workflow plan, not on the $29 chat plan. 料金: From $29/mo. 向いている用途: Teams ready to pay for workflows, not one-off blog posts. ほかのリスト マーケティング向けAIエージェント, おすすめのAI SEOツール, コンテンツ制作向けAIツール. 2 ## Jasper Jasper is a marketing workspace: brand voice, knowledge, audiences, and agents that draft campaigns across channels. The old cheap creator tier is gone. Pro is a single seat with a short trial, and Business is where the agent builder, API, and admin controls live. It is strongest when the job is on-brand writing, and weaker when the job is technical SEO or a live outbound motion. 料金: From $69/mo. 向いている用途: Teams producing a lot of on-brand marketing copy. ほかのリスト マーケティング向けAIエージェント, おすすめのAI SEOツール, コンテンツ制作向けAIツール. 3 ## Surfer Surfer scores a draft against the pages already ranking and against AI-search visibility. Surfy is the writing assistant inside the editor. The product is a copilot for people who ship pages, not an agent that owns an SEO program. Discovery, the entry content plan, starts at $49 a month. Higher plans add more documents and prompt tracking. 料金: From $49/mo. 向いている用途: Writing and revising pages so they can compete in search. ほかのリスト マーケティング向けAIエージェント, おすすめのAI SEOツール, コンテンツ制作向けAIツール. 4 ## Ahrefs Ahrefs is a search dataset: site explorer, rank tracking, site audit, and Brand Radar for AI prompts. The pricing page also lists an MCP server and an API. It is a research suite with AI features, not a product that publishes pages on its own. 料金: Free, then $129/mo. 向いている用途: Keyword, backlink, and AI-prompt data before anyone writes the page. ほかのリスト マーケティング向けAIエージェント, おすすめのAI SEOツール. 5 ## Clearscope Clearscope grades a draft and tracks queries. The pricing page says Essentials includes 50 tracked queries, 50 pages, and 20 drafts a month, and that query tracking covers ChatGPT and Gemini. A person still edits and publishes. 料金: From $129/mo. 向いている用途: Editing a draft against the language that already ranks. ほかのリスト おすすめのAI SEOツール, コンテンツ制作向けAIツール. 6 ## Frase Frase researches a topic, drafts, scores the page, and can publish to WordPress, Webflow, Sanity, or Wix, or host on FraseCMS. The pricing page says the agent publishes on its own only when you turn that on. Content Guard waits for approval unless you opt in. 料金: From $39/mo billed yearly. 向いている用途: Shipping search-led articles with an approval step. ほかのリスト おすすめのAI SEOツール, コンテンツ制作向けAIツール. 7 ## HubSpot Breeze Breeze is HubSpot's agent layer: an assistant on the free CRM, plus content, prospecting, and customer agents that can see the contact record. The interesting agents draw down credits, and the fuller ones sit on paid hubs. It ranks high wherever the team already lives in HubSpot, and it is the wrong first buy if you would be adopting the CRM only to get the agent. 料金: Free CRM, hubs from $15/seat/mo. 向いている用途: Marketing and sales teams whose system of record is HubSpot. ほかのリスト マーケティング向けAIエージェント, コンテンツ制作向けAIツール. 8 ## Writesonic Writesonic tracks a brand in ChatGPT, Gemini, and Google AI Overviews, and includes an article writer and site audits. Agentic workflows are limited trial runs on the self-serve plans. Enterprise is the plan that lists full agent access. A person still publishes. 料金: From $79/mo billed annually. 向いている用途: Seeing where AI answers mention you, then drafting the page. ほかのリスト おすすめのAI SEOツール, コンテンツ制作向けAIツール. 9 ## Clay Clay is a spreadsheet built for prospecting and enrichment. Claygent, its research agent, reads the web and writes custom fields. Waterfalls then try several data providers until a cell is filled. Teams push the rows into a CRM or a sending tool. It does not run a campaign by itself. It prepares the list the campaign depends on. 料金: From $185/mo. 向いている用途: Researching accounts and people before a human or another agent acts. ほかのリスト マーケティング向けAIエージェント. 10 ## UGCBloom UGCBloom is an influencer marketing agent for brands. Specialized agents source creators, run outreach and negotiation, review video, and handle contracts and payouts. A person sets the brief and approves the work. The commercial model is a 30% fee on creator payouts, not a seat license, and the company says you pay for approved, delivered content. It is the wrong tool if you want a synthetic actor instead of a person, or if you want a general marketing copilot. 料金: 30% of creator payouts. 向いている用途: Brands that want human creators and an agent running the campaign ops. ほかのリスト マーケティング向けAIエージェント.
