Reword, structure, or translate your text without leaving the tool you are using. Create custom assistants for meeting summaries, standard support replies, sales pitches, and more. Share them with your team to keep communication consistent and aligned.
In practice:

Expand • Smart snippets: reply in two seconds without copying and pasting
Expand allows you to create reusable snippets: standard replies, signatures, greetings, product explanations, etc.
Type a shortcut (e.g. `/acknowledgment`) → MerciApp instantly inserts “We have received your message and will get back to you within 24 hours.”
Dynamic snippets: customize your templates with variables (customer first name, date, order reference, etc.) to save time without losing personalization.
Share your snippets with your team to keep support, sales, and administrative responses consistent and on-brand.
