Questions & Answers

As answered by people managing Overleaf and Underleaf.

What makes your product unique?

Underleaf's answer:

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.

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.

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.

  • I wrote my PhD Thesis in Typst
    Many people use LaTeX via Overleaf (a Website, cf. https://overleaf.com ) rather than installing it locally. That also solves the problem of having to install locally vairous extension packages or fonts - all is already there, and after writing a paper you may submit it directly to some conferences or journals from that Web GUI instead of having to email it or upload to a third site. - Source: Hacker News / about 1 year ago
