Pick Surfer if your writers want to stay in charge of every sentence, working in a scored editor that plugs into Google Docs or WordPress. Pick Frase if you'd rather hand research, drafting, publishing and weekly fixes to an agent you approve step by step, or you want an answers widget on your own site. Neither is the outright winner.
Picture the person on your team who'll open this tool every morning. Do they want to write, with a score nudging them along? Or do they want to review work that's already been researched and drafted for them? That one question splits this pair better than any feature list, because one of these products is built around an editor you steer and the other is built around an agent that steers itself, with you signing off.
Everything below follows from that split, so keep your answer in mind as you read.
Why older write-ups of this pair now mislead
If you've read a comparison of these two from a couple of years back, it probably pitted one keyword scorer against another. That's not what you're buying now. Both vendors have repositioned around getting content cited in AI answers as well as ranked on Google, and their home pages say so in the headline.
The editor-first vendor has changed shape too. Its site now answers at surfer.ai rather than surferseo.com, and the menu shows it as one product in a wider group that also lists a CRM, an email-signature tool, social media management and a sales dialer. That doesn't change what the content editor does, but it's worth knowing who you're signing up with. The agent-first vendor, for its part, is a single-company platform, and it lists a comparison with its editor-first rival in its own navigation, so it clearly sees that tool as a main competitor.
Where the two split, row by row
| What you're comparing | Surfer | Frase |
|---|---|---|
| Core workflow | Content Editor with a real-time Content Score, an Outline Builder and the Surfy writing assistant | An agent that researches, drafts in your brand voice, scores the draft and lines up the publish, with approval at each step |
| Where it connects | Google Docs, ChatGPT, WordPress and Contentful | Publishes to WordPress, Webflow, Sanity, Wix or its own hosted CMS |
| On-site visitor tool | None described | An answers widget that replies to visitors from your content, with citations, and logs their questions |
| Ongoing monitoring | AI visibility tracking plus a content audit to find weak pages | Weekly Search Console check on guarded pages, with a drafted fix when one slips |
| Languages | English, Spanish, French, German, Dutch, Swedish, Danish and Polish listed | Multilingual listed, no language list given |
| Company shape | One product in a group with CRM, signature, social and dialer tools | Single-company platform |
| Free start | Not stated | Free trial stated |
Three themes that decide it
Who does the writing
The editor-first product gives your writer a live score that, the vendor says, analyses more than 500 web and AI signals as they type. There's an Outline Builder to shape the piece and an assistant called Surfy to help draft sections. Your writer stays in the driving seat the whole way. The agent-first product flips that. It researches the topic, drafts in your brand voice, scores its own draft and lines up publishing, and you approve each step. If your bottleneck is writing hours, that's a big difference. If your bottleneck is quality control, you may prefer the human-led route.
Where the finished piece goes
The editor connects to Google Docs, ChatGPT, WordPress and Contentful, which is handy if your team already drafts in Docs. The agent publishes straight to WordPress, Webflow, Sanity or Wix, and it also offers its own hosted CMS, FraseCMS, if you don't have a site builder you love. So if you're on Webflow, Sanity or Wix, the agent's list covers you and the editor's list doesn't mention them.
What happens after publishing
Both keep watching your pages, in different ways. The editor-first tool tracks AI visibility and runs a content audit to spot weak pages and win back citations. The agent-first tool checks the Google rankings and clicks of pages you've marked as guarded, every week, through Search Console, and drafts a fix when a page slips. One hands you a list of what to improve. The other hands you a draft of the improvement.
The visitor-facing extra only one of them has
Frase Answers is the feature with no match on the other side. It sits on your website, answers visitors' questions from your own content with citations, and captures the questions they ask as first-party demand data. If you've ever wondered what people want to know before they buy, that log could feed your next content plan. The editor-first product doesn't describe anything visitor-facing, so if this matters to you, it's a clear tiebreaker.
A quick checklist before you choose
- Do your writers want to write, or to review? Writers lean editor, reviewers lean agent.
- Is your site on Webflow, Sanity or Wix? The agent lists those; the editor lists WordPress and Contentful.
- Do you publish in Dutch, Swedish, Danish or Polish? The editor names those languages; the agent doesn't list its languages.
- Would a widget that answers visitors on your site be useful? Only one offers it.
- Do you mind your content tool being part of a group that also sells CRM and dialer software? Some buyers do, most won't.
If you want to see how the agent-first platform holds up on its own, my full Frase review goes deeper. And if neither feels right, there's a longer list of tools people switch to from Surfer.
My advice for each kind of team
Go with Surfer if your job is writing and refreshing articles in a scored editor, and you want that editor working inside Google Docs or WordPress, with a clear list of supported languages. Go with Frase if you want one agent to run research, drafting, publishing and weekly fixes, or if the on-site answers widget appeals. Neither vendor's site shows a clear overall winner. It comes down to an editor you drive versus an agent that drives, and only you know which your team needs.

Frequently asked questions
Is Surfer the same company as Surfer SEO?
Yes. The old surferseo.com address now lands on surfer.ai, and the product sits inside a wider group that also lists CRM, email-signature, social and sales-dialer tools.
Can the agent-first platform publish straight to my website?
Its site says it publishes to WordPress, Webflow, Sanity, Wix or its own hosted CMS, with your approval at each step.
Which one writes the content for me?
The agent-first platform researches and drafts in your brand voice for you to approve. The editor-first one gives your writer a live score, an outline builder and a writing assistant, but your writer stays in charge.
Do both track AI search visibility?
Yes, in different ways. One tracks AI visibility and audits weak pages. The other checks guarded pages weekly through Search Console and drafts a fix when one slips.
Is there a free trial?
The agent-first platform states a free trial. The editor-first one doesn't state a free option on its content editor page, so check its sign-up page.
