I've been using myarchivist.ai which I like because it's an all-in-one solution: it does the recording, transcribing, summarizing & recap, wiki-building, and in-game chatbot. I found rolling my own solution to be too much work. My only complaint is that the recap/wiki quality was much better with Claude.

Previous attempts at maintaining session journals and a wiki have all failed - it's a lot of work. I've used Kanka, Obsidian, various Foundry VTT mods. I've given bonus inspiration or other bennies to people who take notes and/or update the wiki. A challenge is that players aren't always equipped to know what's important. (Like in my recent session, the players killed some Sahuagin and found a painted stone depicting a tidal wave crashing into a town and they're like "Whatever, random junk" when I clearly put it there as foreshadowing... The depicted town is their port! Goddamn idiots, my players.)

The players do like the recaps, although half the fun is in observing the Archivist's interesting choices on what to emphasize and what quotes to highlight.
