A lightweight, local editor for the Markdown, HTML, YAML, JSON & config files your agents write.
Gotta catch one of every species, starting with the Kanto region. I want to be the best trainer in the world.
Whatever format your agent used to write it, LocalEditor gives you a normal, editable view — no syntax to learn. Be it a standard md, html, yaml, json or any config file.
Markdown renders like a real page — headings, checklists, tables — and you write in it directly with slash commands. No need to remember syntax.
Canvas format for freeform notes and diagrams. No other editor has this.
⌘K to search across every open folder, files or run commands.
.gitignore, .env, and YAML each get a real, editable view instead of raw syntax.
HTML files render live — real interactivity, no browser tab, no server to spin up.
Scratchpad lets you jot down ideas, one-off thoughts, and quick notes as they come up—without leaving what you’re doing.
Wherever they already are. LocalEditor opens a folder of yours — it doesn't import, copy, or move anything. There is no library and no project format; a "project" is just a folder you picked.
No, and it never will — that's a permanent principle, not a missing feature. Because your notes are plain files in normal folders, any sync you already trust (iCloud Drive, Git, Dropbox, Syncthing) works unchanged.
Markdown (.md) with CommonMark/GFM output plus [[wikilinks]]; HTML (.html/.htm) with a sandboxed live preview; YAML, JSON, .env, and .gitignore each with their own editable, source-preserving view; images, video, PDFs, and CSVs with inline previews; common code files with syntax highlighting; and LocalEditor's own open canvas format for freeform visual notes. Anything else opens in its default app.
Obsidian is built around a connected Markdown knowledge base. LocalEditor is built for reviewing and refining the files your agents create across an existing project.
Yes. Canvas files are plain, versioned JSON, not flattened images — element types, labels, and connections are all in the file. Sketch a wireframe or diagram once and your agent can read it directly as context, no separate design tool or screenshot needed. Canvas is still under active development, so expect some rough edges.
Free for 14 days. After that it's view-only until you buy a licence — a one-time purchase, not a subscription. See Pricing.
macOS only.
LocalEditor is in Beta now. Sign up for access—Beta builds are sent by email as invites open.
Kishan V.My agents write a lot of Markdown, HTML, YAML, and config files, and I want a fast local editor that stays out of the way and never syncs anything to the cloud.
MicahI’m very impressed by the style — usually I use something like Cursor and it feels like far too much for small viewing/editing.
LakeIts simplicity and having a place for my CLIs to go to.
Alex C.Looks super helpful for both my work as a teacher and a software engineer.
Nicolas Q.A middle ground between ide and agentic environment.

AmritIt looks like it might just be that perfect balance of clean minimalism and featured functionality that im looking for.
AmanI really was missing Notepad ++ in Mac Environment.
Skip the heavy setup. LocalEditor reads and edits the Markdown, HTML, YAML, JSON & config files your agents write — fast, and fully local.
