nohmitaina is a desktop editor that auto-extracts concepts from what you write and builds a wiki of how your ideas relate. Inspired by Andrej Karpathy's LLM-wiki idea, but implemented as an editor — write and knowledge live in the same window. Try the new experience of resurfacing — past notes returning to you as you write — that's only possible when the editor and the wiki are one. Works with Claude Code or Codex CLI (no API key needed). Local-first, Markdown, macOS. Free.

I built this for myself because I write every day but my notes never accumulated into actual thinking. After a month of daily use, the wiki started to feel like thinking instead of piling.

Hey everyone — I'm launching nohmitaina next Tue (5/27) and I'd love to talk to a few of you before then.

A bit of context on what I'm trying to solve:

I write a lot. Daily. Sometimes for hours. But when I sit down to actually work through a problem, I can almost never surface what past-me already concluded about it. So I re-derive. Same conclusions, again and again, buried under three months of other notes.

I went looking for an editor built for thinkers — not for documents, not for "second brains" you have to manually structure. Just: a place where the act of writing is also the act of accumulating thought. I couldn't find one. So I built nohmitaina.

Before launch I want to hear from people who feel this problem firsthand:

✅ Do your own past notes ever "come back to you" when you need them, or do they just sit there?

✅ Have you tried building a personal memory layer (Obsidian graph, custom scripts, anything)? What broke?

✅ If an editor could quietly bring back your past thinking while you write — what's the first thing you'd want it to surface?

Trying to talk to as many real thinkers as possible before Tue. Reply here or DM me on X (@simotunes).
