I spent 12 years in threat intelligence reading adversaries from their written moves. A dealer email thread is the same game with smaller stakes.
This free version is the skill + calculator. The paid kit ($29) adds the Deal Room (paste a quote, get the score + counter + walk-away number), the email-by-email Thread Playbook, the dealer Fee Checklist, and a no-terminal install.
