Ai directory tools

Three tools carry the ai directory tag. Two are directories for finding AI software. The third uses directories as part of a marketing service.

AI Services Index groups AI tools, APIs and web apps by category, such as LLM APIs, GPU cloud, vector databases and fine-tuning. It is free and aimed at developers and businesses comparing services. Zoipi is also free and curated. It sorts tools by category, pricing and foundation model, and it lists MCP servers and comparison pages. Citevant is different. It tracks which brands AI search engines recommend and sends outreach to publishers. Its Pro plan costs $95 per month after a $19 first week.
