Will love to buy this once I get my Mac.

Looks great, and also love the perpetual license for $9.99 rather than the host of subscription services, i'll probably end up buying it just to support good practices.

Such an underrated app. I’ve used it for everything from network topologies and storage diagrams and even for my kitchen redesign. Works way better than every pricey specialized tool I’ve tried, and the ASCII outputs look way cooler with their old-school hacker ASCII aesthetic! Highly recommended.
Latest release Apr 2025 introduced a plain text save file format, which plays nicer for source control. Great to see development is still active.
It seems very good, is there anything comparable for Linux?
I’m a big fan of durdraw[1] for crafting ANSI/ASCII art in the terminal, but this takes it to a whole new level, excited to try this especially if it includes color? From the website examples it doesn’t appear to include a color palette, but if it does then game on!

It's a really cracking little app, and great for inline docs.
10 USD?

how does this compare to asciiflow.com which is free and open-source?

Developer of the app here, happy to answer any questions.
Just want to say thanks for a great app. It's one of my favorite tools, even though I don't get to use it that often.
Like many others I also want to express my gratitude for a fantastic app. I bought it in 2016 and it’s seen a lot of use since then (recently almost daily). Being able to copy to clipboard for adding diagrams in source code is the killer feature!
I'm a big fan of Monodraw and use it frequently for ASCII assets / animations for https://oxide.computer.

I'd love some scripting features, to create and edit designs through code. But I'm aware my use case is a little niche.

Nice!

Does it support the new 3x2 and 4x2 mosaic characters (and the HP big 3x3 cell letters) from recent Unicode specs?

I love Monodraw, been using it for years. Keep up the good work!

Was going to politely ask for full dark mode but just noticed from your blog that it seems to be on the way?

I'd expect more of an introduction:

> Harness the Power and Simplicity of Plain Text

Nice tagline, but surely it's not just plain text. It's some unicode shenanigans. How does one make sure their console can display all the necessary characters? How does one make sure others can see their creation?

I just wanted to say thanks for making it. I love this app, use it all the time, and the only thing I wish for is a version for Linux.

Bravo.

Just wanted to say: really love the app. Been using it for years. I love the image overlay since I mainly enjoy making ascii renditions of pictures manually by hand.
I am trying it for the first time. One point of feedback, with the caveat that my only experience so far is opening the tutorial:

I immediately hate that when intending to scroll vertically using the trackpad on my macbook, it constantly unintentionally scrolls horizontally as well and I have to correct it. It is particularly irritating since there is no content on the canvas to see when scrolling.

Maybe I'm just super accustomed to browser scrolling behaviors, which snap scrolling based on initial direction.

I'm mostly posting this because its the kind of papercut that might be forgotten over time.

I’ve now spent a couple hours using it.

Once I started using it for actual diagrams, the issue completely faded away. Scrolling a super long vertical-only document is an unimportant edge case.

This is the god damn holy grail of ascii chart editing.

Well done.

Any plans for a Linux version? Sounds super cool, but I can't run it.
Thanks for Monodraw. I've used it for years and thoroughly enjoy it.
What is the Unicode support? Namely the "Symbols for Legacy Computing"[0] (including the latest supplements [1]) with "newly available" full octants palette could be neat to get sub-character "octant pixel" precision. (And/or exploitation of Braille [2] for the same purpose.)

(Not a Mac user, so cannot try, and not clear from screenshots for me; these all seem like ASCII + )

Any chance for web version?
Accessibility question: how do screen readers handle ascii art-style diagrams like this? It seems like they would be overwhelmed by the lines.
Bought this couple months ago, and am now always looking for more ways to include this for inline-documentation.

the fact i can export to clipboard and re-import it and reconstruct all the shapes etc. almost flawlessly is such a big win.

I'm using this app since its first release.

It's a great simple app I use for inline comment diagrams and more importantly server login banners.

I love to login to a server with a customized banner and a tagline. It's just a small joy makes work more fun.

Being able to include diagrams of what code is doing _inline_ is something that is vastly over looked by the majority of developers.

It's one of the better parts of literate programming without typesetting.

Now, that is something really cool, pity we didn't had something like that on BBS days.
I could have sworn I was using a tool called AcidDraw 30 years ago to design ascii bbbs login screens for use on Renegade systems.
Seems really cool and the price is fair! I'm gonna try it!
Haven't so quickly gone from "woah, that's cool" to "purchase now" in a long time. This is awesome and I will use it daily.

There's a visual simplicity and legibility to the kind of straight-forward but slightly-decorated diagrams shown in the sample images. And the fact that I can now copy-paste them anywhere as well (rather than the classic "screenshot of a Miro or Paint.js board") is so cool.

That’s great. You gained a new customer. In the prompt's and Caves of Qud 1.0 era, I'd say ASCII art is a must, both in terms of UX and aesthetic in general.
Monodraw is great. If I could change one thing, I would make it more expensive. $10 feels like a steal, given the use I've gotten out of it.
Awesome. This is the cleanest ascii-art tool I've seen, so far. To date, I've been using

https://asciiflow.com/#/

and

https://meatfighter.com/ascii-silhouettify/

to create input text for TerminalTextEffects to create terminal animations like the following:

Thanks for posting this. Seems like an incredibly sharp implementation by simply bundling it into an HTML page. Extremely lightweight and portable.
