If you want to use AI to build your own filters for your Gmail inbox, Clean Inbox for Gmail is a good place to start. This extension uses GPT-powered filters to screen incoming messages, letting you weed out unwanted emails, spam and marketing messages. You can browse and install public categories and create your own filter categories with chatGPT technology. That means you can train the AI to screen out similar emails later. The extension offers several pricing options, including a free Hobbyist plan and a Lifetime plan for $29.
Another tool worth a look is Breezemail, an AI-powered email organizer that uses smart categories to keep emails you want in your inbox and send other emails to the right place. It can create custom categories based on ChatGPT queries to make it easier to set up filters. Breezemail comes with prebuilt categories but you can create your own, too, so you can keep your inbox organized. It costs $12 per month, and it's designed to protect your privacy and security. It doesn't sell, keep or analyze data for any reason other than its core service.
If you prefer open-source options, Inbox Zero is a Google-backed personal AI assistant designed to help you get control over your email. It can automate tasks like unsubscribing from newsletters and blocking cold emails, and it can perform tasks like automated responses, a one-click newsletter cleaner and cold email blockers. You can train the AI with plain English commands and approve its actions before they take place. It works with Gmail and Google Workspace email accounts and can be self-hosted for better data privacy.
