What to watch out for
The free version caps AI edits and PDF downloads each week, so heavy use will push you toward the paid version. AI-generated LaTeX is a starting point and may still need manual review, especially for complex math or custom formatting. Because it is browser-based, you need a stable connection to work smoothly. Free limits and paid terms can change over time, so confirm current details before relying on it for a deadline. Check that the templates and export formats match your target journal or school requirements.
