Nextdoor AI is the AI layer built into Nextdoor, the neighborhood network used by over 100 million verified neighbors. Powered by OpenAI's ChatGPT API and Nextdoor's own LocalGPT models, it helps you write better posts, get AI-summarized local recommendations, create marketplace listings from photos, and build ad campaigns with generated copy and images. The AI draws on 15 years of hyperlocal conversation data to deliver answers specific to your neighborhood.

• AI Post Assistant:Helps neighbors write and improve posts for better engagement. It suggests rewritten versions of community updates, questions, and recommendations that users can edit before posting.
• Faves (AI Local Recommendations): Ask questions like "best family-friendly hikes nearby" and get AI-generated summaries pulled from real neighbor conversations.
• For Sale & Free AI Listings: Assists users in creating marketplace listings by generating titles, descriptions, categories, and suggested details from uploaded photos or short inputs.
• AI Ad Copy & Image Generator: Advertisers enter a short prompt about their business, and the AI creates full ad copy and images using ChatGPT and Pexels' photo library.
• AI Click Optimization: Uses machine learning to improve ad performance by automatically adjusting targeting and delivery to increase engagement and click-through rates.
• Real-Time Alerts: AI-enhanced alerts for weather, traffic, power outages, and safety concerns with color-coded risk levels on a neighborhood map.

• Hyperlocal AI Foundation: Uses large-scale neighborhood conversation data to generate answers based on real community activity and local context.
• Free for Residents: All AI features for neighbors (post assistant, Faves, listing generator, kindness reminders) are included at no cost.
• Improved Community Safety Signals: AI-based moderation tools help reduce harmful content and encourage users to revise potentially negative comments.
• Strong Ad Performance: AI-powered click optimization has delivered significant improvements in CTR and engagement efficiency for advertisers.
• AI-Assisted Marketplace Listings: Helps users quickly create For Sale & Free listings by generating titles, descriptions, and categories from inputs and photos.

• Limited to Nextdoor's Ecosystem: AI features only work within the Nextdoor platform. You can't use them as standalone tools or integrate them elsewhere.
• RRecommendations Depend on Local Data Quality: AI-generated summaries can feel broad or less actionable in areas with limited community activity.
• Geographic Availability Varies: AI features launched first in the U.S. and are still rolling out to other markets like the UK. Not all neighborhoods have full access yet.

• Selling Items Locally: You have a couch to sell but hate writing listings. Upload a few photos and the AI generates a complete For Sale post with title, category, suggested price, and description. Edit if you want, then publish in seconds.
• Finding Local Service Providers: Need a trusted plumber or electrician? Use the Faves feature to ask your neighborhood AI. It pulls from years of real neighbor recommendations and gives you a summarized answer instead of making you scroll through dozens of posts.
• Small Business Advertising: You run a local bakery and want to reach nearby customers. Enter a short prompt about your business in Nextdoor Ads Manager, and the AI generates ad copy, selects relevant images, and optimizes delivery for clicks.
• Community Post Writing: You want to organize a block party but aren't sure how to word your post for maximum engagement. The AI Assistant suggests a revised version that's clear, friendly, and likely to get responses.
• Neighborhood Safety Updates: During severe weather or local emergencies, real-time AI-enhanced alerts show color-coded risk levels on your neighborhood map, pulling from partners like Weather.com and Samdesk.
