Hint launches AI app for home maintenance and management with Martha Stewart as co-founder

Hint, an AI startup co-founded by Martha Stewart, launched an iOS app that aggregates public property data, user-uploaded documents, and an AI assistant to help homeowners manage maintenance, energy use, insurance, and repairs. Users begin by entering their home address, after which the app constructs a home profile using public records such as property details, weather, soil data, and utilities. Users can also upload contracts, inspection reports, warranties, mortgage documents, insurance policies, invoices, and photos of appliances.

The app generates a personalized maintenance schedule that evolves with the home’s systems and environmental context, sending proactive push notifications for tasks like replacing water filters, vacuuming refrigerator coils, flushing water heaters, or checking well salt levels. Martha Stewart, a co-founder and CTO Kyle Rush say she is actively involved in product design, branding, and content review, providing feedback on the app’s outputs and design decisions.

Hint’s AI chatbot allows homeowners to query their home data for information ranging from service histories to energy rates or insurance deductibles, and can guide decisions about home equity lines of credit or insurance claims. The app also assigns a “home score” summarizing the user’s management of the property.

The startup was originally focused on decarbonization incentives before pivoting to a broader home management platform. Hint is backed by $10 million in funding from investors including Montauk Capital, Brian Kelly (The Points Guy), Slow Ventures, Tusk Venture Partners, Energy Impact Partners, Amplo VC, and Hannah Grey. The iOS app is available for free without subscriptions or ads, with plans to add premium features for managing additional properties while keeping core AI features free.

Hint uses commercial AI libraries, primarily from OpenAI and Gemini for image processing, and generates affiliate revenue from a partner network of service providers, which Rush says is firewalled from the AI’s recommendations to avoid bias.
