Athena VS phimpme-android

This setup can be used to create a 'push button' assistant (which is in fact what I am in the process of setting it up for) where you quickly record your command, and once finished it runs through the whole processing pipeline. I will be releasing more python/java scripts to do just this, and eventually turning it into a native Android app once I've formalized some of the design. I figured it was something people in this sub might be interested in. You can get the APK, the sample launching script, and the setup instructions on my Github. If you're interested in following the project you can do so at r/SapphireFramework

This project is still in early but you could like it https://github.com/Tadashi-Hikari/Athena

Google Assistant: Dicio is already on F-Droid but it won't get what you are saying. Possible actions are limited. There's also Athena that's in development, though it is not ready for any kind of use. Depending on whether you need some sort of an accessibility service, you can get away with ditching Ok Google / Alexa / Cortana / Bixby. TalkBack should help with it too.

Along with what you said, the Athena project also seem like interesting - even though you have to build it. Yet this video indicates that the developer knows what he is doing

Athena - intends to completely replace Google assistant,

Athena and the Sapphire framework

Maybe Phimp.me could suit you?

I hope that and Phimpme gets updates in the near future.

Snapspeed: The closest thing you're getting is Phimp.me, which is far from a polished app. Don't use an image editing app, try Phimp.me if you must, go with Snapspeed if you really need those features.

Phimp.me is the only FOSS Android image editor that I know of.
