## What is AI Services Index?

The site is a catalogue of AI products. Each entry carries a name, short description, category, a pricing label (Free, Freemium, Paid or Open Source) and a link to the tool. Categories on the homepage include LLM APIs, GPU Cloud, Inference & Serving, Vector Databases, MLOps & Monitoring, Fine-tuning, AI Security and Developer Tools.

Beyond the listings, the site has a news section, a compare section and guides. The homepage reports 2,164 published tools and 320 guides. It highlights hand-picked featured tools and a feed of recently added ones. A submit page lets makers add a tool that is missing. Its llms.txt says entries come from public announcements, developer communities and direct submissions.
