  • Gmail plugin AI that learns from my emails?
    I work a sales / client service job for a tutoring company, and I write a lot of emails for it. Most of the emails I receive are pretty similar to others I've received before, and the emails I write are very similar to ones I've written countless times. However, the communications I do are very specific to my industry, so generic autocomplete (such as compose.ai) doesn't produce useful suggestions. Source: over 3 years ago
