Jasper is a general AI writing assistant for marketing copy. SEOAgent gives your coding agent the tools to build and improve SEO pages in your codebase — measured against real Search Console data, approved by you.
Install the Skill — freeSEOAgent is the SEO engine for coding agents. It ships as a free Skill for Claude Code, Cursor, and Codex (plus a local CLI) that audits your site and builds landing pages and blog articles directly in your repo. The optional cloud layer analyzes Google Search Console performance, researches competitors and keywords, and proposes evidence-backed updates — which your coding agent implements only after you approve them.
Jasper is a versatile AI writing assistant that runs in its own browser app. It generates blog posts, ads, emails, and social content from templates and brand-voice settings. It is flexible across marketing channels, but the output lives in Jasper until you copy it out, and it is not grounded in your search performance or your codebase.

SEOAgent works inside your codebase through your coding agent. Pages, metadata, schema, and internal links are created and edited as real files in your repo — and ship through your existing CI/CD.
Jasper works in its own browser app. You generate drafts there with templates and brand voice, then copy the text out and handle SEO, optimization, and publishing yourself.
If your site lives in a codebase, SEOAgent keeps SEO where your work already is. If you need fast multi-channel copy in a browser, Jasper fits that flow.
The cloud layer grounds suggestions in your real Google Search Console data and competitor research, then proposes specific, evidence-backed updates. Nothing changes until you approve it.
Jasper generates content from prompts and brand-voice settings. It does not measure search performance, so deciding what to write and what actually ranks is left to you.
SEOAgent leans on your own performance data and keeps a human in the loop on every change. Jasper is built for fast generation, not measurement-driven SEO.
Built for founders and dev/SaaS teams who ship their site from a repo and already use a coding agent. Local-first, developer-credible, grounded in your real expertise rather than AI slop.
Built for marketers and content teams who need versatile copy across ads, email, social, and blogs from a single browser app.
Pick SEOAgent if a developer or coding agent touches the site. Pick Jasper if a marketing team needs broad copy beyond your website.
SEOAgent’s Skill is free forever and runs locally; the $49 per-site cloud tier adds Search Console measurement, research, and review. Jasper is a subscription writing app with no free working tier — verify its current plan pricing on jasper.ai before quoting it.
They solve different problems. Jasper generates general marketing copy in a browser; SEOAgent gives your coding agent the tools to build and improve SEO pages in your codebase, grounded in Search Console data. If your site lives in a repo and SEO is the goal, SEOAgent is the more natural fit.
Jasper does not measure search performance or optimize against your real rankings by default. You handle keyword targeting, on-page SEO, and publishing yourself. SEOAgent grounds its suggestions in your own Search Console data and builds the changes in your repo.
Yes. Some teams draft long-form copy in Jasper, then use SEOAgent to build and continuously improve the pages in the codebase with real performance data. They serve different stages, so there is little overlap.
The Skill is free forever and runs locally. Pro is $49 per site per month and adds Google Search Console analysis, competitor and SERP research, and cloud review of suggested updates that sync back to your repo with one command.
