Questions & Answers

As answered by people managing ProseMirror and Underleaf.

What makes your product unique?

Underleaf's answer:

Underleaf is built specifically for people who write in LaTeX. Unlike generic AI writing tools, it understands mathematical structure, equations, and academic formatting. It can convert PDFs and handwritten notes directly into clean LaTeX, generate TikZ diagrams, and help refine technical writing - all while preserving document structure. Itโ€™s designed to feel like a natural extension of your LaTeX workflow, not a replacement for it.

Why should a person choose your product over its competitors?

Underleaf's answer:

Most tools treat LaTeX as plain text. Underleaf treats it as a first-class language. Itโ€™s purpose-built for researchers, students, and technical professionals who care about correctness, structure, and reproducibility. With deep support for equations, diagrams, and academic formatting - plus seamless Overleaf integration - Underleaf saves hours without compromising precision or control.

How would you describe the primary audience of your product?

Underleaf's answer:

Underleaf is built for professors, researchers, graduate students, and technical professionals who regularly write in LaTeX. This includes people in mathematics, physics, engineering, computer science, and related fields who want to move faster without sacrificing rigor or formatting quality.

What's the story behind your product?

Underleaf's answer:

Underleaf was created out of firsthand frustration with how slow and manual academic writing can be. After years of writing papers, notes, and technical documents in LaTeX, the goal became clear: remove the friction without breaking the workflow researchers rely on. Underleaf started as a personal productivity tool and grew into a platform that helps thousands of academics write faster, cleaner, and with more focus on ideas instead of syntax.

  • 10 Best WYSIWYG Editors for Web Developers in 2026
    TipTap is a headless WYSIWYG editor built on top of ProseMirror. It gives developers full control over the UI while handling complex editing logic under the hood. This makes it a strong fit for highly customized interfaces. - Source: dev.to / 7 months ago
  • Top 5 Page Builders for React
    While Storyblok and Builder.io offer full-page editing experiences with structured CMS capabilities, Tiptap takes a different approach. Itโ€™s not a traditional page builder but rather an embeddable headless editor built on ProseMirror. This means that instead of giving you a predefined UI to work with, it provides the underlying logic, leaving you in full control of the interface, interaction and level of... - Source: dev.to / over 1 year ago
  • Ask HN: How to integrate a Blog system into my NextJS app
    > One thing I learned is that you should lean towards letting non-technical people choose their own tools like why we largely let developers choose their own tools. IMHO: I think a more sustainable variant of this (for your own sanity) might be to ask them which tool(s) they like and then take some time to understand WHY. But then instead of just letting them use those directly, you would either vet them first... - Source: Hacker News / almost 2 years ago
  • Open Source Contribution: Round 2
    However, after doing some extensive research, I realized that almost none of them were compatible with Svelte, and those that were did not offer what I was looking for. That is, until I found tiptap, which is a headless wrapper around another WYSIWYG editor called ProseMirror. However, ProseMirror is very low level, and tiptap is super Svelte friendly! - Source: dev.to / almost 2 years ago
  • Word-like HTML inline edit with design mode
    I love how Trix [0] and (I think) ProseMirror [1] work in that regard: it does use contenteditable, but every edit you make is applied to an internal model instead, then the editor state is updated back from the model.
