Signals is a web-based tool that uses artificial intelligence to analyze chat conversations, helping users interpret the emotional tone and intent behind messages. Its primary function is to convert ambiguous or mixed signals from text exchanges into a clearer assessment of the other person’s attitude, such as warm, avoidant, or low-effort. The tool then provides reply suggestions that align with the observed communication pattern, offering both immediate next steps and longer-term strategies for managing the relationship. The platform is designed for individuals who want to understand the dynamics of a conversation without relying on guesswork or emotional reasoning. The core workflow involves pasting a chat transcript into the interface. The AI processes the text and returns an analysis that includes a score not as a standalone number, but with contextual clues explaining why a particular attitude was identified. Users can also view a sample analysis before submitting any real data, which auto-plays on the first visit. The tool accounts for cultural differences in communication, noting that phrases and tones vary across Chinese, English, and Japanese conversations. It also highlights potential risks such as manipulation, pressure, mixed commitment, or dragging behaviors, and allows users to track trends over time to see whether the relationship is progressing or stagnating. Key features are organized into tiered plans. The basic plan includes three lifetime analyses, one relationship profile, basic reply suggestions, and danger signal alerts. A higher tier offers 30 analyses per month, five relationship profiles, like score trends, AI context association, and three reply suggestions per analysis. The privacy boundary is emphasized: the homepage only displays sample analysis, and no real conversation data is shared before the user chooses to submit it. The tool is intended to serve as a checkpoint for decision-making, helping users decide whether to push forward, send a lighter message, or stop chasing a conversation. It is not a replacement for direct communication, but rather a supplement for gaining clarity on patterns that are otherwise easy to misinterpret.
