Tteollim is a relationship-focused service that helps people make sense of their romantic interactions through AI-powered analysis of chat conversations. Users can paste an exchange and receive a report in about 30 seconds, with insights based on patterns such as reply speed, changes in tone, and who tends to initiate contact. The service covers questions about mutual interest, the early stages of dating, relationship fatigue, shifting affections, possible infidelity, and arguments.

It also offers self-guided relationship tests, including a range of ten tests, for users who want to reflect before analyzing a conversation. Beyond diagnosis, Tteollim provides a reply coach that suggests what to say in the user’s own style, along with date-place recommendations for couples planning to meet. The site also features a community and relationship-related reading materials.

Tteollim presents its analysis as a way to understand where a relationship may stand, rather than relying only on guesswork. It states that original chat conversations are not stored, and offers a simple process: paste a conversation, let the AI analyze it, and receive a report
