Curio

Most recommenders guess from genres. Curio reads what you actually wrote. You journal games as you go — after the first evening, forty hours in, or the moment one loses you — and every entry carries your real Steam playtime, so you see how an opinion moved, not just where it landed. That builds a taste profile which sorts your unplayed library into tiers, each pick linked back to your own words. Free, MIT-licensed, self-hostable. Bring your own Gemini/Claude/OpenAI key.
