AI Analysis

●●SolidCozyShip It

Atomic saves with fsync+rename and sha256 content-addressed images show real craft.

Strengths
  • •Atomic save pattern (write-temp → fsync → rename) prevents file corruption on crash.
  • •Content-addressed image storage with sha256 hashing is a clever deduplication approach.
Weaknesses
  • •Markdown editor space is saturated with Obsidian, Typora, and iA Writer.
  • •No breakthrough feature that would make users switch from established tools.

Post Description

Hello, I'm Hyunbin.

Recently I made 'Rune' which is a small desktop .md writer/editor.

I am aware that there are a lot of .md editor out there. but i wanted to build .md editor by myself.

Major features :

- Atomic Saves (write-temp -> fsync -> rename) so a crash can't corrupt a file, debounced autosave.

- Pasted/dropped images are content-addressed (sha256) into an assets.

- Workspace folder + file tree, Chrome-style tabs

- Interactive task checkboxes, readable/wide width toggle; self-contained HTML and PDF export

- currently supports English/Korean/Chinese/Japanese

Any sort of feedback / contribution is always welcome.
