Show HN plan (working draft)

Living plan that I refine before launch day.

Title

Show HN: mdfy – Your AI memory, deployable to any AI

Alternates I'm holding: "Markdown URLs as a memory layer for Claude, ChatGPT, Cursor" / "I built the personal wiki Karpathy described, then deployed it as a URL." Current preference is the first — leads with our line and the cross-AI differentiator.

Body — target ~400 words, no marketing language

Opens with: "I've been building mdfy for ~8 weeks. Today I'm shipping v6, which turns it from a markdown publisher into a memory layer."

Then: the thesis (LLMs read markdown, URLs cross every boundary, so your memory should be a markdown URL).

Then: what it does today, bulleted.

  • Capture from any AI (Chrome ext, MCP, paste).
  • Capture from anywhere else (GitHub, Notion, Obsidian, files).
  • Bundle by topic with AI-synthesised analysis.
  • Hub auto-clustering into a concept index.
  • llms.txt + bundle digests + recall API.
  • Cross-AI wiring via AGENTS.md / CLAUDE.md / .cursor/rules.

Then: what's interesting (in my voice).

  • Cross-AI is structural moat.
  • Authored memory ≠ extracted memory.
  • Graph-RAG-as-URL (not Graph-RAG-as-service).
  • The Karpathy wiki shape, deployed as URL.

Then: stack. Then: try it (free, no signup).

Then: "Happy to dig into anything technical, the cross-AI thesis, why I left X to do this, or where I think this goes if it works."

Anticipated questions, pre-drafted answers

  1. Isn't this just Notion + AI? — Notion's AI works in Notion. mdfy works wherever the URL goes.
  2. What about Mem0 / Letta / extracted memory? — Different question. Mem0 asks what the AI should remember; mdfy asks what you want to remember.
  3. How is this different from GitHub Pages + markdown? — Capture surfaces, hub layer, cross-AI deployability.
  4. Won't AI companies just build this? — They structurally can't. Their incentive is the wall.
  5. Pricing? — Free during beta. Pro $X/mo after launch (price TBD).
  6. Why are you doing this? — Trillions of tokens of high-quality AI-assisted thinking are being created daily and lost to chat histories nobody returns to. I want to catch the part you actually meant to keep.

Timing

Tuesday or Wednesday, 7 AM PT. I'll be online and responding for 6 hours minimum.

What I'm explicitly not doing

  • Recruiting upvotes from Slack.
  • Posting in any other forum within 24 hours of the HN post.
  • Buzzword pile-up.
  • Reddit-style "let me know what you think!" tail.
