Overleaf online LaTeX editor

Why online first

Overleaf removes the worst part of LaTeX for beginners: installation. Open the browser, pick a template, press compile — the PDF appears next to the source with errors highlighted in place. Nothing to install, no missing packages on day one.

Collaboration without pain

Sharing a project link beats emailing zip archives with v7-final-final in the name. Simultaneous editing, per-author colors, full history and comments cover the whole co-author workflow, including reviewers who have never seen LaTeX.

When to go local

Move local when compiles get slow (big theses with many figures), when you need shell-escape or exotic packages, or when the work must live offline. Export the project as a zip — it compiles locally unchanged.

Git instead of history

Overleaf history is fine for a week; a thesis lives for years. Clone the project as a git repository and push to your own remote — meaningful commit messages beat «restored from history» archaeology when the committee asks what changed since March.

Offline backup habit

Cloud-only work dies with the account: download the full zip monthly and confirm it compiles locally. The fifteen minutes also catch the moment your project quietly depends on an Overleaf-only package that the local TeX Live lacks.
