A minimal, clean interface — designed to feel good, not just work somehow.

Why Duditor

Four ideas Duditor was built around.

A comfortable place for your .md files, versions you never have to think about, sharing without attachments, and no price tag.

An editor built for reading and writing .MD comfortably

AI agents and people increasingly keep their working material in plain .md files — notes, specs, prompts, instructions. Duditor is the editor for that: no hashes or asterisks on screen, proper formatting, good design — and the kind of comfort you already expect from an ordinary text editor.

→Formatting instead of symbols
Headings, lists, tables and code blocks render the way they read. Switch to Source whenever you want to see the raw markdown.
→Editing tools where you need them
Select text to get a formatting toolbar, or type / to insert a heading, list, table or code block.
→Ordinary files, nothing proprietary
Every document stays a plain .md file in your folder — the same file your agents, scripts and teammates already open.

Every change is saved and versioned (with Git)

Your team, your engineers, and any AI agent working on the files always see the same, current version — and nothing you write is ever lost.

You don't need to know a single git command for any of this. Save your version, pull in everyone else's changes, see what changed — it's all a handful of clear buttons, no terminal, no jargon.

→Saves as you type
There is no save button to forget. Your work is on disk the moment you write it.
→See exactly what changed
Added lines show in green, removed lines in red — in the formatted view and in Source.
→Clashes explained in plain words
If two edits disagree, Duditor shows both side by side on a simple screen and lets you pick.

Share your local documents in one click

Want someone to see what you're working on right now? Just send them a link — no exporting, no attaching a file to an email, no converting it to a PDF first.

Everything you've shared lives in one place: if you forget what you sent and to whom, it's easy to check — and just as easy to revoke access at any time. You can also see who's opened it, and how often.

→A link instead of an attachment
The person you send it to reads a clean, formatted page. No app to install.
→One list of everything you've shared
Check what went out and revoke any link with one click.
→Views at a glance
See how many times each shared document has been opened.

Everything above, completely FREE to use

No seats, no subscription, no "contact sales." The editor, the git integration, the sharing — all of it is free, with nothing held back behind a paywall later.

→No seats
Bring the whole team. Nobody is counting accounts.
→No trial clock
Nothing expires after 14 days or asks for a card.
→No paywall later
The features on this page stay free.

Duditor is the experimental family project

No company behind it, no investors to answer to. An engineer who wanted a better markdown editor, and an artist who made sure it didn't look like one.

Dudie for Andrew

Andrew Grabarnick

Founder & Engineer
I built Duditor because I wanted a great editor and viewer for markdown files with git built in — and nothing like that, that was actually pleasant to use and didn't lag, existed yet. It also became a bit of an experiment: could I build and launch a real product almost entirely with AI — product, design direction, marketing, all of it? And since I wanted it to actually look and feel good, not like something an AI churned out on autopilot, I brought in an artist I trust completely — my wife. This turned into a family project in the best way.

Dudie for Manuna

Manuna Grabarnick

Artist

I am an artist behind Duditor's look and feel. I designed Dudie, the app's little mascot, and shaped the whole visual world around it — because software doesn't have to look like software.
