Paste a short chat and preview how SparkAI reads it

This preview runs locally and does not upload content. Full AI analysis, saved history, and practice chat require login.

Paste at least 3 lines of chat to see a short preview.

Read hidden signals

Detect interest, coldness, tests, and the current relationship stage from real chat records.

Get sendable replies

The output includes concrete reply options, not just abstract advice.

Practice with simulated replies

Let AI mimic their style so you can rehearse before sending the real message.

Generate social post ideas

Create natural posts based on your history, interests, and current relationship context.

Try first, pay only if it helps

New users receive signup credits for the first analysis. Paid packages start at ¥9.9.

Logged-in chat records are used for your analysis results and saved history.
You can delete people, chat records, and analysis history.
