Best for Multimarkdown

It is not yet the 'perfect' markdown editor, but it is going in the right direction and as close as they come. I can say that having tried almost every other such program on the market.

In terms of room for improvement, the template system for both the editor experience and the HTML presentaton should be primarily CSS instead of the anomalous, one-off JSON format that makes customization unnecessarily difficult, but other than that and some rough patches during previous development, I am faithful to this great editor. To address some of those shortcomings I recommending pairing this with another app called "Marked". The two together are critical to the way I craft and leverage markdown. The result is that I truly enjoy writing and especially the almost instant capacity to turn plain text into a beautiful PDF, HTML or any of a number of other formats.

I don't often write reviews, but given how much I have benefitted from this program I felt compelled to give it a shout, and endorse it wholeheartedly.

Essential writing tool for scientists and others

I am a radiology professor and write research papers as part of my living. I also write a lot of non-medical text as part of my hobbies (folk music, folk dance, fiddle music, etc) and activities on various non-profit boards).

Virtually all of my writing for all of my projects starts out in Markdown, which means Multimarkdown Composer most of the time. The instant preview of my work is essential. The ability to mix images, tables, equations and references is also essential to me.

I am a bit of an alpha geek, so there are times when MMC doesn’t do what I need. When I need to do a lot of custom formatting, I use BBEdit with grep. When I need to mix my text with statistical analyses and graphics, I write in RStudio with RMarkdown. When my work requires scientific computations in SciPy or NumPy, I turn write in Markdown in a Project Jupyter notebook.

However, the bulk of my writing is handled quite nicely by MMC. Once my main writing is done in MMC, MMC does an awesome job of exporting my work to HTML, LaTeX, Scivener or (ack, ptui) Word as needed. I also appreciate the efforts Dr. Penney has made to have MMC work with Critic Markdown and Marked2.

MMC is the premier Markdown tool I recommend to friends and colleagues who ask for my advice on writing tools.

Go-to editor that just gets better!

I’ve used MultiMarkdown Composer for going on 6 years and it has become my primary writing tool for ALL uses - documents, client call notes, planning. The ability to create documents in MultiMarkDown and see the rendered HTML output in real time is powerful and efficient. I can copy as HTML and paste into our corporate collaboration tool as HTML and retain all of the formatting, saving me significant time and ensuring my content is communicated in the way I want. On the rare occasions I’ve had questions or (largely perceived) issues, the developer has always been timely and knowledgable in responding. Great tool, great team.
