Plugin & App Store-Style AI Ecosystems

These platforms function like app stores for AI tools, particularly those that plug into GPTs, chatbots, or LLMs. They provide not only tool listings but also allow users to preview prompt interactions, test capabilities, and rate performance. Some are linked directly to GPT stores or Google Extensions, and may even include revenue-sharing programs for tool builders. These directories are ideal for users seeking AI tools tailored to large language model platforms like ChatGPT, Claude, or Gemini.

Tools:

• GPTStore.ai – A specialized directory for GPT-based apps and plugins, showcasing bots, assistants, and LLM-enhanced workflows. Offers previews and links to official OpenAI ChatGPT store listings.

• WhatPlugin.ai – A curated store of ChatGPT plugins, agents, and extensions with filters for task types and integrations. Great for finding useful add-ons for content creation, search, and automation.
