- Kayla Topp
- Being in sales and writing/replying to emails all day, I’m constantly going back and forth between my email and ChatGPT to copy and paste drafts. It’s such a game-changer to be able to do everything directly in Gmail and use whichever model fits the task. So convenient. I loved it so much that I introduced it to my coworkers, and now they’re using it too!
- Brandon
- Quality extension that makes replying to emails a whole lot better.
- John Stevenson
- Super useful and easy to use! Love it.
- Jason Ghent
- Useful tool to make email writing simpler. Nice!
- Hugh
- Very simple to use, integrated directly into gmail, and allows you to select which AI model is used. Would recommend it, especially if you're looking for an affordable and accessible option.
- Chance Corbett
- Love this tool. I am a independent consultant and I am constantly replying to emails from my clients. This helps me respond faster, and I love the fact get to pick my own model (I usually use the latest OpenAI models). Found this to be a less expensive option than some of the other tools i've tested and this also gives better responses from the context of the thread.
- Nathan Braun
- I really like the onboarding for this extension. It guided me through installing it, pinning it in my browser, and then showed me how to actually use it in gmail. So far I'm happy with the emails that it generated for me. Super easy to use extension.
