fxSolver is a free tool developed by a team of engineers and programmers with the sole intention of providing a unique, useful and free service. The vision of the development team is to allow students, engineers, and hobbyists to come in contact with mathematics and to be able to solve problems without necessarily being familiar with professional math software or programming languages.
Underleaf is an AI-powered workspace built for researchers, students, and technical writers who work in LaTeX. It helps you move faster from idea to polished document by turning messy inputs into clean, structured LaTeX - without breaking your workflow.
With Underleaf, you can:
fxSolver UnderleafUnderleaf'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. Itโs designed to feel like a natural extension of your LaTeX workflow, not a replacement for it.
Underleaf's answer:
Most tools treat LaTeX as plain text. Underleaf treats it as a first-class language. Itโs 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.
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.
