It replaced three separate AI subscriptions. The model switcher alone saves me hours every week.

Image generation, web search, file uploads. It's the AI workspace I've been waiting for.

Incognito mode is a game-changer for legal research. Everything else just works.
Claude, ChatGPT, Gemini and Grok, with the lineup keeping expanding. You switch between models in one click, mid-conversation.
Yes, just ask. Logos, illustrations, product mockups, photoreal scenes. Images stream into the chat inline and you can download or share them in two clicks.
Your conversations are encrypted, never used to train public models, and you can flip any chat into Incognito mode to exclude it from your history entirely.
Kiin combines the top AI models in one chat, throws in image generation, live web search, file uploads and a clean workspace, for less than a single ChatGPT Pro subscription.
Yes. Drop up to 10 files per message (PDFs, images, CSVs, code, docs, up to 20MB each) and ask anything about them: summarise, extract, translate, critique.
