What to watch out for
Free access and the exact feature set can change as the product evolves, so confirm current terms on the site. Merlin depends on upstream AI services, so availability and quality can vary. Browser extensions request permissions, so review what access you grant before installing. Treat AI output as a draft to check rather than a final answer, especially for important messages or research. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data. When quality matters, export a small draft first to confirm the result before producing the final file.
