EmoGPT

Free to use, EmoGPT is a ChatGPT browser extension for Gmail that writes email replies, follow-ups and outreach templates from inside your inbox.

As an AI email writer, it runs on OpenAI's ChatGPT and aims at personalized drafts rather than generic boilerplate.

Privacy is the main selling point.

EmoGPT lets you plug in your own API key, which gives you more control over how your data is retained than a shared account would.

If you are wary of sending client correspondence through yet another third-party service, that option matters.

The scope is narrow, and that is part of the appeal.

EmoGPT is built for Gmail and does one job: helping you get through email faster, with drafts you can edit before sending.

There is no paid tier to weigh up, so the only cost you might face is whatever OpenAI charges for usage if you bring your own key.

Good for people who write a lot of outreach or follow-up mail and want a simple add-on instead of a full writing suite.
