At a glance

Adot (에이닷, A.) is SK Telecom's AI personal assistant app/web service. Without signing up separately, you can pick and use its in-house model A.X and outside AIs such as ChatGPT/Claude/Perplexity in one place and compare their answers. It bundles call recording/call summaries/interpreter calls (Adot Phone), Adot Note for organizing meeting/lecture recordings, schedule management and morning briefings, so it suits SKT subscribers and anyone who wants to organize daily work with AI. In August 2026 SKT was selected as an operator of the government's "AI for Everyone" (모두의 AI, free AI for all citizens) project and is preparing the official service within the year.

Full model list

These are the models you can choose in Adot's "search" feature. We could not find material in which SKT officially discloses the full current list, so this is compiled from the list known as of late 2025 (Namuwiki/press reports) and the wording on the official website. Models may have been added or replaced since, so check the model selection screen in the app.

Which plan to choose

Free (basic): People who want to compare answers on one screen without subscribing to ChatGPT/Claude/Perplexity separately. Good for casually trying several AIs and choosing the model that suits you. However, there is a daily usage limit, so it may fall short for heavy users.
Adot Phone: SKT subscribers who have many work calls and want to record/summarize them, especially those who need call recording on an iPhone.
Music agent: People who have T Membership and want to get music recommendations by chat and listen.
AI for Everyone: All citizens who want to use domestic AI without cost once it launches. We recommend watching the launch schedule.
