# Built a weather app with AI-generated summaries and city bookmarking—feedback welcome (took me 9-10 days; learned a lot) > Source: > Published: 2026-07-25 14:10:31+00:00 Hey everyone, wanted to share a project I just finished. It's a weather app, but I tried to push past the typical "fetch API, show temperature" tutorial project. Features: AI-generated natural language weather summaries instead of raw numbers Dynamic backgrounds that change based on real weather conditions City search with live suggestions as you type Bookmark/favorite cities, persisted with localStorage Stack: React + Vite, deployed on Vercel Stuff that actually gave me trouble: Debouncing the city search so it doesn't spam the API on every keystroke Duplicate city names across countries messing up search results Bookmarks kept vanishing on refresh until I realized I wasn't persisting state properly Syncing background image changes with API response timing without a jarring flash It took about 9-10 days total, mostly because I kept refactoring state management once bookmarks, search, and multi-city display all had to interact. Still learning, so genuinely open to criticism — especially on component structure, since that's where I feel least confident.
