Epicenter
ChatGPT's memory feature in an open, portable format
If you are part of Epicenter (or you are a YC founder who looks at Epicenter 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 Epicenter
Epicenter is building ChatGPT's memory feature in an open, portable format. This means you can take your entire chat history and plug it into another app, so it knows you instantly. Our long-term vision is to become the SSO for AI applications. Users use Epicenter to plug into any service, and they'll own their data, choose their models, and replace siloed apps with interoperable alternatives. Developers will use our framework to build highly customized experiences for said users. Right now, we're leading by example by building our own suite of tools on top of Epicenter. We store all your work—notes, transcripts, chat histories—in a single folder of plain text and SQLite. Every tool we build shares this memory: your text editor, personal assistant, and so on. It's open, tweakable, and transparent. Grep it, open it in Obsidian, host it wherever you like. The choice is yours. You should own your memory in the same way you own your brain. ❤️

- 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.
