Questions & Answers

As answered by people managing Smith.ai 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. It’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. It’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.

  • Are remote jobs dying?
    Being a VA, have you seen smith.ai ? I dont work for them or anything, but they are hiring 16usd /hr. Source: about 3 years ago
  • Desperately looking for work
    What remote sites are you using to search for jobs? If they are the most popular, most are saturated, there are so many people looking for jobs right now! If you are bilingual and have customer service experience, smith.ai is paying 16/hr for bilingual virtual assistants in the US. It should be dead easy for you to get in, most the application is automated, just make sure you have all the hardware and software... Source: over 3 years ago
  • Gabbyville Virtual receptionist
    I've been debating using a live answering service. I have a chat answering service called ngage. I'm OK with them but not impressed. What makes you like smith.ai so much? Source: over 3 years ago
  • Phone service
    Google Voice is a good option, especially on a budget. I'd just make sure that you are answering the phone every time! Especially if you are going to try running LSAs, or have a website, etc - not answering can negatively impact your results/rankings. If you are looking for coverage after-hours, smith.ai is also a good option, but may not be something you want to pay for. Source: over 3 years ago
  • Not sure if this is the place to ask, but I didn’t get any responses on r/lawschool so y’all are up to bat: do 2L law clerk positions at mid/small firms lead to opportunity for post-graduation employment? Or is that exclusive for summer associates?
    No one really. Two lawyer partners and a bunch of virtual/independent paralegals, smith.ai answering service, an executive suite, etc. Source: almost 4 years ago
