About Us
Markdown tools that respect your text
Markdown Editor AI is a free collection of Markdown editors, converters, and generators that run entirely in your browser. No accounts, no uploads, no waiting on a server to format a paragraph.
Why we built this
Markdown solved a real problem: it gave writers a way to add structure to plain text without leaving the keyboard or committing to a proprietary file format. What it never solved was the gap between typing a marker and knowing what it will actually look like. Every platform renders a slightly different subset, trailing spaces are invisible, and a single unclosed backtick can quietly swallow the rest of a sentence.
Most tools that close that gap ask for too much in return. They want an account before showing a preview, or they upload the document you were trying to keep private just to convert it. We wanted the opposite trade: open a page, paste the text, see the result, copy or download it, and close the tab. That is the whole product, and it is the reason every tool here is a static page with the work happening on your own machine.
What we believe
Your document never leaves your device
Every editor, converter, and generator on this site runs entirely in your browser. There is no upload step, no server-side processing, and no copy of your text on our infrastructure. You can disconnect from the network after the page loads and the tools keep working.
No accounts, no paywalls
There is nothing to sign up for and nothing to unlock. We would rather build a tool that is useful in the ten seconds you need it than a product you have to onboard into. Drafts are saved in your own browser storage, not in a database we control.
Accurate to the spec, not to a guess
The general editor follows CommonMark plus GitHub Flavored Markdown. The Discord tools follow the dialect Discord actually implements, which is deliberately different — no tables or images, but underline, spoilers, and subtext. Our cheat sheets render their own examples through the real renderer at build time, so the preview cannot drift from the documentation.
Fast, and quiet about it
The site is statically generated and ships interactive code only on the pages that need it. Heavy dependencies such as the HTML converters are loaded on demand instead of being bundled into every route, so a cheat sheet lookup stays as light as it should be.
What we make
The site is split into two families of tools. The Markdown tools target the portable syntax you use in README files, documentation, issues, and static sites. The Discord tools target Discord's own dialect, which looks similar but behaves differently enough that a shared editor would mislead you.
How the site is built
Pages are generated ahead of time, so most routes are plain HTML and CSS by the time they reach you. Interactive tools are mounted as small islands only where they are needed: the editors share a single CodeMirror instance, rendering goes through markdown-it for the general dialect and a purpose-written parser for Discord, and PDF export happens locally in the browser. Untrusted HTML is passed through a sanitizer before it is ever rendered, and raw HTML in Markdown stays disabled unless you explicitly turn it on.

Frequently asked questions
Is Markdown Editor AI really free?
Yes. Every tool on the site is free to use with no account, no trial, and no usage limit. Because the work happens in your browser, our running costs are limited to hosting static files.
Does the site use AI to edit my writing?
No. Despite the domain name, there are no AI features and nothing you type is sent to a language model or any other external service. The name reflects the domain we publish on, not a processing step.
Where is my work stored?
Drafts are stored in your browser using localStorage, which stays on your own device. Clearing your browser data removes them, and we have no way to recover them because we never had a copy.
Can I use the output commercially?
Yes. You own everything you write and everything the tools generate from it. We claim no rights over your content or the Markdown, HTML, and PDF files you export.
How do I report a bug or request a feature?
Use the contact page. Bug reports that include the input you used, the browser you were on, and what you expected to happen are the fastest to fix.
