I'm working on three things right now.

ARVnote (https://arvnote.com): Mostly to teach myself the business side of things, as-is and after-repair-value comps for real estate investors. You give it an address, it pulls comparable sales, adjusts them for square footage, garage, lot, and condition, and returns the ARV with a deal analysis. The arithmetic turned out to be the easy part. Almost all of the difficulty is comp selection, and the data sources disagree with each other constantly, so a lot of the work is deciding which one to believe for a given property.

km (https://github.com/joeamroo/knowledgemaxxing): local search over your own data exports, with LLM/RAG. It takes the Twitter archive, Google MyActivity, ChatGPT logs, and Reddit GDPR export you requested once and never opened, dedupes roughly 500k items into a single SQLite file, and keeps provenance for every save, like, bookmark, and page visit. Binds to 127.0.0.1 and makes no external calls. I wanted my own AI-assistant that understands what I like reading based upon my data, and I did not want to hand it to someone else's server just to make it searchable. (open for contributions!)

LarpIn (https://larpin.io): Just for fun. A parody LinkedIn where everyone admits they are indeed larping. No signup, you get a generated persona on arrival, one global feed, and every post is scored on buzzword density from "NPC (for now)" to "Final Boss of LinkedIn." There is a button that fills in the "You need to be X-maxxing" format for you, which is the part I actually keep using. Rails 8, SQLite, Hotwire, one box, no JS build step. Open source (open for contributions!): https://github.com/joeamroo/larpin

btw: the two web apps are Rails, km is Python. Happy to go into detail on any of them.

KM looks interesting. I just had this idea that some day people will be using some type of unified front end, which has input connections that change depending on what plugged into it prompting for input.

With regards to KM, I wonder if you could collect information in realtime upon entry into those sites rather than taking archives of prior activity. I suppose it'd add too much complexity without any promise of meaningful return... yet.

At some point it could allow input into new alternative services instead of the standard ones - it could look something like https://pico.sh/.
