neutron VS Leon

PS: I hope that we selfhosters will have a modern, efficient, easy to use mail suite one day with modern features like JMAP, good self-learning spam integration, automated checks and validations for SPF/DMARC/DKIM or whether the IP/host suddenly appears in a blocklist and integrated encryption at rest for emails. Something that isn't 30 services in a container image, with 30 different configuration styles. Maybe even with an API integrated that's compatible to the ProtonMail frontend (like the neutron server once intended to be). Anyway, I'm sorry for dreaming. ;)

A bit related: there was a FOSS backend once but I don't think anyone wants to push further.

Some folks once started neutron which is an email server that can be used with the FOSS Protonmail web client but it was abandoned. And I guess you'd want to support JMAP in addition to IMAP as well apart from having automated encryption of incoming plain-text emails.

Anyway, to the topic: there was once neutron which is a server that aimed at ProtonMail compatibility. So that'd would simply would be able to use the same open source frontend from ProtonMail. However, this was abandoned. So you, or somebody else, could revive it.

Some folks also started implementing an FOSS ProtonMail but this project was abandoned at some point. But maybe someone will fork and revive it one day.

Two devs once started implementing a free ProtonMail server but they abandoned it. It's understandable, since it's a lot of work.

Some folks once started a free implementation of the Protonmail backend in Go. Maybe you want to revive it?

Some folks also started an open source Protonmail backend but this was abandoned at one point.

It's indeed suspicious. You're sending your voice samples, your various services accounts, your location and more private data to some proprietary black box in some public cloud. Sorry, but this is a privacy nightmare. It should be open source and self-hosted like Mycroft (https://mycroft.ai) or Leon (https://getleon.ai) to be trustworthy.

I literally had this thought a couple of days ago and went down a small rabbit hole looking into it too! There's some stuff out there (I saw Mycroft and Coqui mentioned in the comments already, also check out Leon, Jarvis, and OA although not sure they all deploy to Linux) but ultimately, I just don't think the tech is there yet.

Mycroft is pretty decent and there are a few other similar open source projects if you're interested (https://github.com/MycroftAI, https://github.com/leon-ai/leon)

Take a look at Leon I'm not sure it's what you're looking for but it look pretty awesome.

Leon is an open-source personal assistant who can live on your server. He does stuff when you ask him to. You can talk to him and he can talk to you. You can also text him and he can also text you. If you want to, Leon can communicate with you by being offline to protect your privacy.

There is also Leon - https://getleon.ai. But I’m not using any of the self hosted yet.
