capacities.io has a feature where you can send a message from WhatsApp/email/Telegram/Facebook messenger and automatically make a note. It accepts photos too.
Unfortunately, the data can’t be exported yet, so that site appears to have no use.
Still, there should be a way to set this up for Obsidian, possibly using existing tech of some sort. All we need is a bot that can read messages and save them locally into the vault.
and if you have the WhatsAPP app on your desktop as default link opener, it’ll open right at that contact. I haven’t figured out how to share info yet other than copy/paste, but I think it’s possible.
Going the other way isn’t possible without more hacky stuff afaik, such as (often dodgy but very widely used) 3rd party apps that link into web.whatsapp.com
I made a greasemonkey script to put a shortcut to the client details from web.whatsapp.com but that was before I was able to use the other shortcut
It’s messy, but it’s what most of the world are forced into, which is why there’s so many 3rd party stuff trying to help with the situation
In absence of anything better, I use Drafts. The only problem is that it relies on Obsidian sync so I have to remember to open the Obsidian iOS app so that the sync is initiated. It’s a frustrating process and no idea why Obsidian team doesn’t provide easier options.
