About Chemistry — Conversation HUD
Chemistry is a real-time conversation HUD for adults using X direct messages. See language signals from your conversation and unsent draft while you type.
FEATURES
• Mutual Spark: an estimate of mutual engagement in the conversation.
• Your initiative and their initiative: signals of conversational participation.
• Flirt, reply hook and pressure: feedback on the wording of your unsent draft.
• Sex/intimacy signal: describes sexual language and context, not consent or the probability of sex.
• Full HUD and compact display modes.
HOW IT WORKS
Sign in with Google, open an X conversation and activate the HUD. Chemistry analyzes loaded conversation text and your draft to update its indicators. It never sends messages on your behalf.
DATA PROCESSING
When activated, conversation text and your unsent draft are sent to the Chemistry service and TypeSafe/Jev for analysis.
ACCESS AND PRICING
An account is required. The free trial includes 10 conversation sessions and 200 analyses in total. The paid plan is US$9.90 per month and includes 150 conversation sessions and 8,000 analyses per billing month. Both limits apply. Paid subscriptions are subject to availability.
Scores are estimates of language signals, not facts about another person's feelings, intentions or consent. More messages do not necessarily mean a higher score.
Chemistry is an independent product and is not affiliated with or endorsed by X.
