ChatGPT for Gmail Chrome extension

ChatGPT for Gmail adds AI writing tools directly into the Gmail compose window, generating subject lines, full emails, and thread summaries without needing your own ChatGPT account. It's best for anyone who writes a lot of email and wants faster drafts. The catch: it's built by Salesgear.io, not OpenAI, so quality and prompt limits depend on their implementation.
