CoreAI

CoreAI is an AI multi-model aggregator that gives you access to 300+ language and image models — including GPT-5, Claude, Gemini, Grok, Kimi, and DeepSeek — through a single subscription and login across web, iOS, and Android. Instead of paying for several separate AI apps, you chat in one place and can switch models mid-conversation. CoreAI runs prompts through multiple models side by side so you can compare answers and pick the best output for a given task, and it supports file attachments, image generation, and scheduling recurring AI tasks. Accounts sync across devices, so a conversation started on the web continues on mobile. The tool is aimed at people who regularly use more than one AI assistant — writers, developers, and researchers — and want to consolidate billing and compare models without juggling multiple tabs and subscriptions. CoreAI is free to start, with paid Premium and Max tiers for higher usage and priority access.

Best for heavy AI users who want GPT-5, Claude, Gemini, and 300+ models in one subscription and side-by-side comparison.
