   Frase

   Research, draft, and an optional publish step

   Pricing

   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.

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.

   Pricing

   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.

   Key features

   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.

3. 3

   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.

   Pricing

   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.

   Key features

   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.

   Pricing

   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.

   Key features

   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.

5. 5

   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.

   Pricing

   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.

   Key features

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

6. 6

   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.

   Pricing

   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.

   Key features

   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.

   Pricing

   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.

   Key features

   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.

   Pricing

   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.

   Key features

   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.
