The LINE compatibility diagnosis & chat analysis app everyone's using — "MeroTalk"
Simply import your LINE chat history,
and your relationship will be classified into one of 16 types.
The other person will never find out.
Chat content is analyzed entirely on your device without going through the internet.
(Internet connection is required only when using AI features)
"What kind of distance does this ongoing relationship really have?"
"Are our feelings actually out of balance...?"
—Those relationships that are hard to put into words become visible through data.
