Well, compliments for your work but allow me a note: products, especially modern ones, have a very little shelf life, AI is actually a different kind of search engine, good for some kind of search but easy to allucinate so... It's a dream of some giants to keep ruling the people because they count to be the sole with enough data and resources to train models and probably use training biases to direct popular opinion and believing, it's not a landscape for small actor, with unbearably high costs and probability of very little revenues.<p>So my suggestion: learn tools that will gives you power, learn LaTeX to write documents well, it's sound banal but consider a thing: in the past with pen and paper the sign of education is good writing, not we write with computers, good typography is the new sign, LaTeX, TiKz/PGF allow to produce beautiful looking docs very few knows how to make. Learn how to OWN your infra, with desktop tools, not clone of some giants web service.<p>This base will gives you no money at first and maybe not much excitement but gives you the basis very few now have to going anywhere you want in IT. Notes? Notes means text, the most used tool to store, transmit and transform knowledge, so well, notes like Emacs/org-mode/org-roam are "notes", you can insert code listings, evaluating them live, attach files, handling personal finance with PTA tools like BeanCount or Ledger, full-text-search anything, export to LaTeX or a website, trying to compete against these feature is a giant task asking for years of development, trying to make this software for the masses is the way to push again people toward FLOSS because it became "current" again, profiting from the technically more vast, best and free codebase on the planet without selling "Open Source Enterprise" and with instead of on top and against the community.
