Character Chat is an exploratory study into how Claude Opus 4.7 can power a new generation of historical and educational tools. Users hold real-time, in-character conversations with historical figures — Frida Kahlo, Sigmund Freud, Simone de Beauvoir, and Salvador Dalí — each rendered as a pixel-art avatar with reactive emotes and a themed environment that reflects their world. The problem it solves: History and humanities education often feel static — textbooks, lectures, and Wikipedia pages. Students rarely get to engage with the figures they study. Existing chatbots either break character instantly or default to a flat, encyclopedic tone that strips away personality, contradiction, and emotion — the very things that make these figures worth knowing. The approach: Character Chat uses Opus 4.7's adaptive extended thinking to match cognitive effort to the question being asked. Casual greetings get a fast, reflexive reply (thinking disabled). Medium-depth questions trigger a 2,000-token thinking budget. Genuinely philosophical prompts ("what is suffering in art?") unlock a 6,000-token deep-thinking pass, so Frida actually thinks before answering — the way she would have. Combined with structured stage-direction markers parsed by the frontend, the avatar reacts emotionally in sync with the response. It's a study, not a final product: a testbed for how Claude's reasoning capabilities can transform passive historical content into living, in-character dialogue for classrooms, museums, and cultural institutions.
