Nowsletter is a collaborative tool for getting event-data from email newsletters using local and small AI. Corrections can be made in a collaborative setting, this way you get simultaneous corrections, approval and AI-bias-check. These events can then be published further, for example on the AT protocol (~Bluesky).
It is used at joelsnewsletters.com

It's for any person or organisation who wants to get event data from various newsletters organised in a calendar, and then potentially publish those events to the AT protocol (~Bluesky).

I made this for myself, to be able to stay up to date without using social media. Most events I cared about were available as newsletters, but they were hard to overview. I realised afterwards that this is potentially useful for others.
Why not just grab the data from various websites, or perhaps from Instagram?
The main reason is that newsletters are intentional. If you don't want me to have your newsletter you can remove me from your list, so there is already a consent mechanism built in. Consent becomes a bit blurry when 'scraping' websites. Instagram actively don't want you to have their data, so that becomes a cat-and-mouse type of process.
Newsletters are low-tech, anyone can make one, a sort of dinosaur from an earlier internet - but they're still around. Its a more stable base to start from.
I'm planning to make this open source as soon as I cleaned up the code a little bit more.
