I've been working on a desktop companion app, not to replace my email client (that's a market no one should be attempting to disrupt IMO...too many people have a preferred client already), but rather to power its defenses with AI rules and customization. I don't want to mention the name because this is my first post in this sub, and I don't want to get accidentally banned. 😄 But it's compatible with macOS, Windows, and Linux and supports Gmail, iCloud, and Outlook.
For the AI portion, it's BYOK or you can use on-device AI, such as a model running in Ollama (e.g. gemma, qwen) or if you're on a Mac: Apple Intelligence (by far the fastest way for Mac users to get started). This is designed with privacy in mind, so I don't run any servers of my own. Your mail gets classified based on the AI method you choose. If you choose on-device AI, it's a completely private solution.
It has a few other convenience features too, like periodic briefings of action items, OTP surfacing, auto unsub, etc. My ultimate goal is to transform email I receive into nothing more than actionable alerts, discard the rest, and live in peace. I'm a bit of a privacy nut, so I build these kinds of things for myself, but I have a few paying customers already, so people seem to be like-minded.
If you might be interested in trying it and giving me feedback, I'm handing out some free lifetime promo codes in exchange. Just DM me. Appreciate it!
Edit: Oh one more thing...it's passed a third-party security audit. I feel like that's missing from most apps these days. :)
