1. 1

   Frase

   Research, draft, and an optional publish step

   Frase is the one on this list that will publish to a CMS if you turn that on. Starter is $39/mo billed yearly, with a 7-day trial and no card. Leave the publish switch off until you have read a week of what it ships.

2. 2

   Surfer

   Writing and revising pages to a content score

   Surfer leads because an 'AI SEO agent,' in practice, is a writing assistant tied to what already ranks. Surfy plus the editor is that product, and Discovery starts at $49 a month with a public price. It will not audit your backlinks.

   Precio

   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.

   Funciones

   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.

   Qué dicen

   Quienes llevan años con Surfer en Trustpilot dicen que el editor de contenido muestra huecos y palabras clave semánticas sin adivinar.

   Otras reseñas dicen que el precio es alto para lo que hace, y una dice que no hay forma de quitar la tarjeta después de cancelar.

   • “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.”

   Writesonic

   AI-answer tracking plus a draft

   Writesonic Starter is $79 a month billed annually, with a trial and no card. It tracks ChatGPT, Gemini, and Google AI Overviews and includes a monthly article allowance. It is not a backlink index. Use Ahrefs or Semrush for that.

   Precio

   From $79/mo billed annually

   writesonic.com/pricing lists Starter at $79 per month billed annually, Basic at $199, and Growth at $399, each billed annually. Enterprise is custom. Annual billing saves 20%. The FAQ says you can start a trial with no credit card, and that there is a 7-day refund. Last checked 5 October 2026.

   Funciones

   Google Search Console, WordPress, GA4, Looker Studio. Self-serve plans include a limited number of agentic workflow runs. Publishing still needs a person.

4. 4

   Semrush

   The broader SEO suite, with AI as a copilot

   Semrush is the suite people mean by AI SEO tools: keywords, audits, rank, competitors. Autonomy is intentionally low. Evidence is high because the product and the price ($139.95/mo for Pro) are public. Pair it with Surfer or Jasper when the gap is the draft, not the data.

   Precio

   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.

   Funciones

   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.

   Qué dicen

   Unas reseñas cortas de Trustpilot siguen llamando útil el tramo gratuito y dicen que el producto hace un buen trabajo.

   Las reseñas largas recientes describen una cancelación que mantiene viva la suscripción y un cargo tras una prueba que la persona creía gratuita.

   • “Generous free tier, good for analytics”

     Trustpilot

   • “I really love this service. They do a great job!”

     Trustpilot

   • “They are an unscrupulous company that tricks you into keeping the subscription active.”

     Trustpilot · Fserra

   • “Free Trial is Extremely misleading. I got charged for a full month even through i attempted to cancel several times.”

   Ahrefs

   The search dataset, including AI prompt tracking

   Ahrefs is the dataset Semrush is usually compared with. Lite is $129/mo and a free plan exists. It does not draft and publish the page. Use it when the gap is data, then hand the brief to a writing tool.

   Precio

   Free, then $129/mo

   ahrefs.com/pricing lists Ahrefs Free, then Lite at $129/mo, Standard at $249/mo, Advanced at $449/mo, and Enterprise at $1,499/mo. Content Kit is an add-on from $99/mo. Cancelling a paid plan drops the account to Ahrefs Free. Last checked 5 October 2026.

   Funciones

   API, MCP, Looker Studio. A person runs the reports and decides what to publish. The suite does not ship the page.

   Qué dicen

   Una reseña de Trustpilot dice que el equipo reembolsó un plan que no encajaba y que el producto sigue teniendo funciones de SEO útiles.

   Otras dicen que una investigación normal dispara un bloqueo por actividad sospechosa, que los créditos se acaban rápido y que el soporte no restaura el acceso.

   • “Team happily provided a refund for the tool. I tried it for a specific use case which was not what the tool was built for, but it certainly has useful functionality for SEO.”

     Trustpilot

   • “I’ve been using Ahrefs for my SEO work, but lately it has become almost impossible to use.”

     Trustpilot

   • “You sign up for a plan thinking you can do some keyword research but GUESS WHAT: It's credit based.”

     Trustpilot

   • “Such bad organic traffic data, what a scam of a site misleading people.”

   Clearscope

   Grading a draft and tracking AI answers

   Clearscope starts at $129/mo with a 14-day trial. It is closer to Surfer than to Ahrefs: you bring the draft, it tells you what is missing, and you still publish.

   Precio

   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.

   Funciones

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

7. 7

   Jasper

   First drafts you will still have to optimize

   Jasper integrates with Surfer, which is the tell. It is a marketing writer that can feed an SEO workflow. It is not an SEO platform. Job fit stays at 18, just above a partial-fit cut.

   Precio

   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.

   Funciones

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

8. 8

   Copy.ai

   Short marketing copy, not technical SEO

   Partial fit. Copy.ai can draft a brief or a meta description. It does not know why a URL dropped. Keep it off the critical path of an SEO program.

   Precio

   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.

   Funciones

   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.

   Qué dicen

   Una reseña antigua de Trustpilot dice que Copy.ai ayudó con las descripciones de producto.

   Reseñas posteriores dicen que el acceso dejó de funcionar, que el soporte no contestó durante meses y que los prompts guardados desaparecieron tras una actualización.

   • “Copy Ai is great. It helped me a lot with my product description. But ever since I upgraded, the composition is shorter compared to my free trial.”

     Trustpilot

   • “It had a paid subscription and used it a bit, but my login stopped working. Reached out to support via email and via the website form. No response for months even after several messages.”

     Trustpilot

   • “I was an enthusiastic used and ambassador. then the service just stopped working. nothing works.”
