Hashnode

Hashnode is a blogging platform rebuilt around being cited by AI assistants as well as found on Google. A hosted blog is free to start, written in a Markdown editor with code blocks, LaTeX and Mermaid diagrams, tags, series, comments and team roles. The Pro level lets a custom domain be mapped with SSL handled for the writer, offers AI writing tools and scheduled posts, and opens a GraphQL API for running your own frontend. Coding agents can sign in over MCP with OAuth to draft, edit and publish. The Growth level adds AI search tools: each day it asks AI assistants questions and records who they cite, shows sessions arriving from ChatGPT, Perplexity, Gemini and Claude by assistant, gives drafts a live AEO score with editor checks and a fix for each failure, and adds FAQ blocks with structured data, an llms.txt file and AI crawler controls.
