Who is using ProseMirror?


We are thinking about transitioning to ProseMirror…at first we are putting a toe in and looking around (we just had a great call with Marijn).

I was wondering if anyone here would like to share what they are doing with ProseMirror and a link to their project? It would help us get a sense of what the community is doing and how big it is etc as this is a little hard to tell. We suspect there are a lot of people doing interesting things with it, but its hard to know from the website and forum alone…

Anyone wish to say something here about there project, perhaps with a link? May also be a useful resource for others thinking of joining…


I’m building a qualitative analysis product called Dovetail that uses ProseMirror as its core editor. Dovetail lets you organise user feedback or research interviews by letting you code the content (tagging fragments of text). e.g.

I recently added automatic sentiment analysis backed by Google Cloud Natural Language.

All of this is done in a real-time collaborative editing environment using ProseMirror’s collab protocol (with our own server implementation). There’s a lot more information about the product on the web site, so check that out if it sounds interesting.


Nice website Bradley. Product looks really cool!


Forestry.io is using Prosemirror for our Markdown editor for static sites

You can read more about it here!


We are using it at https://www.dabblewriter.com/ for our novel writing software. And I know we’re not the only one in our space doing the same.


We are using it at https://www.edition-unik.ch/

Edition Unik is a project targeted primarily at elder people who want to write a book with personal texts. We define a restricted document schema for ProseMirror, which really helps with the translation of the resulting document to LaTeX and to PDF for a result that can be directly sent to a print shop upon completion.


We’re using it at https://www.nuclino.com to build an easy knowledge base for teams.


your product looks really good. I’m working on something with annotations also. can you share how you were able to show your annotations in the margin aligned with the highlighted text? looks really nice!


Hi @adam,

SciFlow is a publishing platform for scholarly writing. We use ProseMirror as the basis for our collaborative editor. You can try it for free at www.sciflow.net - let me know if you have any questions.

Best regards Frederik


Tropy is a free and open source app for working with photos / archival sources. We’re happily using ProseMirror for Tropy’s note pad using both horizontal and vertical (right to left) input.


We run Missive, a collaborative email client allowing teams to chat within email threads and collaboratively compose / review email drafts in real time.

In our first version, we used Firepad because it provided collaborative editing somewhat effortlessly. You can imagine how people have very strict requirements regarding email and old habits anchored in other apps (Gmail, Outlook, to name a few). Here’s the one thing we hadn’t thought of that made Firepad a deal breaker: spell checking. Firepad’s rendering does not use contenteditable, which makes browser-native spell checking impossible to provide. Big bummer for many people.

We started searching for a contenteditable-based tool that supported collaborative editing. At the time, ProseMirror was the only candidate left after discarding Quill due to its overly simplistic document model (no nested lists nor multi-line quotes) and I believe this still holds true today. ProseMirror has actually come a long way to allow proper spell checking. Marijn very kindly responded to feedback on this topic and ended up rewriting significant parts of ProseMirror to support it. I am extremely thankful for his dedication.

To build our collaborative editing backend, we started from the ProseMirror website example (see code here) and adapted it because we obviously need to store data in a database, not just in memory. See this great article on the design of ProseMirror’s collaborative module if you are interested.


Basically just use the http://prosemirror.net/docs/ref/#view.EditorView.coordsAtPos API to calculate the top-offset of each annotation, then separately render a sidebar with with position: absolute items running down the page.


Thanks! will give that a try…
