User Reviews

Paperpal for Overleaf is praised for seamless Overleaf integration, effective grammar suggestions, and preserving LaTeX formatting, which together speed up and improve academic writing. A user-friendly interface and time-saving features are common positives. However, multiple reviews report recurring login issues, raising reliability concerns. Some mention occasional false errors and broader site compatibility challenges, but when it works, the extension significantly enhances Overleaf-based writing.

Pros

Direct integration with Overleaf, making editing and grammar checks work inside the editor
Helpful grammar and writing suggestions that save time
Preserves LaTeX formatting and avoids altering LaTeX code
User-friendly interface that streamlines research workflows
Enhances overall quality of academic writing

Cons

Frequent sign-out/login instability (users report being logged out quickly)
