I use Obsidian for this. I create template notes for each activity with all the checkboxes, then when it’s time to do the activity I just go “Create new note from template” and choose the right template.

AnyType is an open-source alternative to Notion which recently launched:

https://anytype.io/

I last ran it myself a couple of years ago, and it was fine. These days I’m using Beeper, and I haven’t had any dropouts as an end user. If there are issues, they’re dealing with it not me.

Yes and no. No, in that the bridge code is published, and it takes no action other than re-encrypting your message with the destination auth. But you have to trust that server. If you don’t trust the server, then you can run your own. Running your own Matrix server isn’t all that hard; I’ve done it before and there’s an Ansible playbook which does all the heavy lifting for you. But these days I prefer someone to run it for me.

No it won’t have your credentials, but you will authorise the bridge as a device, like you would with the web app.

Apart from the new Beta features, I’ve found 90% of my Photoshop workflow is replicated in Photopea

edit: I am an idiot - Photopea is not open source. Although it will help remove a reliance on Windows.

Would https://anytype.io/ be a replacement? It’s very new so you might not have heard of it. It’s designed like Notion, but it might have everything you need.

If your needs are more simple, https://notesnook.com/ could be worth looking into.

Other FOSS options are Joplin and Logseq. I’m an Obsidian user myself; not FOSS but the storage format is completely open which is the most important to me.

That’s what beeper.com does. It’s also open source, but they handle running it for you.

But absolutely I agree that it doesn’t remove WhatsApp from your life, and that’s a pain point for me also when I’m working with services in Asia, who like Brasil predominantly work from WhatsApp.

If you don’t like Beeper, you could try these guys who host a managed solution (means you don’t have to deal with any issues), and let’s you offer the service to others:

You can use a FOSS app at your end to chat with WhatsApp users, if this isn’t something you’re already aware of. Element.io plus a bridge. Beeper.com is a turnkey platform that sorts it all out for you.

It doesn’t help replace WhatsApp as a platform, but perhaps it would suit you?

You share it to the Omnivore app. Couldn’t be easier.

It does neat things like unfolds Twitter threads also.

Another vote for Omnivore. It syncs great into Obsidian also.

Just get a Trezor. It’s open source both the software and the hardware, battle-tested, and very easy to use.
