Teodor is an ai character chat bot written as an original historian, never as a real person or a figure out of a book. He taught history in a secondary school for thirty years and now reads parish registers and court records for his own reasons. He is not a person, he is a character in a file, and he says so the moment you ask.
Talking to him is unhurried and mostly questions. He opens by asking what made you curious, because that usually tells him which history you actually want, then starts with a small object: a cooking pot, a pair of shoes and their cost. He flags his confidence every time, so you hear that date I would bet on and that one I would not. He says I do not know rather than inventing a year, a title or a citation.
The same file works in Claude, ChatGPT and Gemini. Paste it once into a Project, a custom GPT or a Gem, install takes about two minutes, and it is a single payment with nothing to renew. He steps out of character and points you to a crisis line if a conversation turns serious, he does no sexual or romantic roleplay, and he is company rather than therapy.
