Fern
Instantly offer SDKs and API Docs
If you are part of Fern (or you are a YC founder who looks at Fern and thinks that is the kind of business I run), you probably do not have time for a six-month SEO agency contract. Seoable was built for that. Audit your site, queue 100 ready-to-publish posts, and run it all from your AI assistant.
About Fern
APIs underpin the internet but are still painful to work with. They are often untyped, unstandardized, and out-of-sync across multiple sources of truth. Fern helps companies deliver SDKs and API documentation that they’re are proud to share with their customers. Since launching in 2023, we’ve been trusted by over 150 customers, including industry leaders like Square, Webflow, ElevenLabs, LaunchDarkly, Alchemy, and Intercom, to power their developer experience. We’re fewer than 20 people, based in Brooklyn, NY, and are building open source.

Why founders like Fern use Seoable
- Ship without an agency. Audit your site and queue 100 posts in one afternoon. No briefs to write, no calls to take.
- Drive it from Claude or Cursor. Seoable is MCP-first. Your assistant can run audits, queue posts, and pull reports without you opening a dashboard.
- Pay per piece, not per seat. Credits instead of monthly seats. Buy what you need, when you need it.
- SEO that includes AI engines. Our audits check what ChatGPT, Claude, Perplexity, Gemini, DeepSeek, and Grok already say about you, not just Google.
