Show HN: Cardog – AI interface for vehicle ownership

by samsullivan on 2/23/25, 8:25 PM with 6 comments

Hi HN! I wanted to share something I've been working on after an interesting pivot. Last year I built a vehicle search tool that ran into legal issues with major listing sites. That experience led me to tackle a different problem - making the entire car ownership experience more accessible and data-driven.

Ended up building an AI interface that helps research any vehicle, access documentation, and manage ownership - think having a car expert, market analyst, and personal assistant rolled into one. Core features:

- Natural language interface to research any vehicle, parse manuals, and search relevant web/YouTube content (think perplexity for cars) - Monitor market values and listings across North America - Track maintenance, service records, registration dates for your garage - Store ownership documents, recall info, service bulletins

Live demo: https://cardog.ai | Example: Ask about reliability ratings for the latest SUVs or "What should I look for when buying a used Model 3?"

Would love to hear what aspects of car ownership you find most frustrating.

    It seems that there are currently no SUVs available for under $45,000 in your area (Toronto, ON) within a 50 km radius.

    If you're open to expanding your search criteria, such as increasing the price range or considering different body styles, please let me know, and I can assist you further!

    Great first impression with design but you lost me after 1 search

    Hey, is not accesible :

    500: INTERNAL_SERVER_ERROR Code: MIDDLEWARE_INVOCATION_FAILED ID: cdg1::c6j9r-1740442231005-18f5698b5887

    Could you ask what legal issues you had with other listings? As far as I know, scraping publicly available information is legal. I want to develop something similar for another category. Thanks!

    this feels like a feature of claude.ai or chat.deepseek.com not a stand alone product. I can already get what you are selling for "premium" for free with deepseek search toggle.
