Questions & Answers

As answered by people managing Trix 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.

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.

  • NanoChat โ€“ The best ChatGPT that $100 can buy

Its inability to use files over a network is a big limiter. Basically everything HyperCard could do is something the... - Source: Hacker News / 11 months 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.

  • Quill โ€“ Your powerful rich text editor

    Trix was the winner. It was easy to style, is well maintained, has documentation for embedding it into a form, is easy to create custom keyboard shortcuts for, has great examples on how to save/load content or modify it with javascript. Source: over 2 years ago
