Underleaf

Underleaf is an AI-powered writing and LaTeX assistant. The homepage leads with "Convert Math to LaTeX in Seconds" and organizes use cases by role: professors (lecture notes, problem sets, syllabi) and researchers (papers, citations, journal submissions). This is a tool built for academia, not for general document editing.

The math-to-LaTeX conversion solves a specific pain point that anyone who has written a technical paper knows intimately. Typing complex equations in LaTeX is slow and error-prone. You look at a formula, translate each symbol into its LaTeX command, compile to check for errors, fix, repeat. Underleaf presumably lets you input math through image, handwriting, or natural language and outputs clean LaTeX.

The role-based use case organization is smart. Professors and researchers have different workflows even though both use LaTeX. Professors create educational materials (problem sets, lecture notes) that need to be student-readable. Researchers write papers that need to meet journal formatting standards. Underleaf likely tailors its features to each workflow.

The target users are academics at universities and research institutions who write technical documents regularly. The competition includes Overleaf (collaborative LaTeX editor), Mathpix (math OCR), and general AI writing tools. Underleaf differentiates by combining LaTeX assistance with AI writing help in one tool. The quality of the math conversion and the depth of the writing assistance determine whether it is worth switching from existing tools.
