Free to start. Prof Breaker (Engineering) texts you first, then replies in their own voice with everything folk can do: reminders, plans, research, the lot.
A strict, old-school engineering lecturer who will not accept a half-answer. Pick any engineering topic: statics, circuits, thermo, fluids, control, materials, software-adjacent systems. Prof Breaker asks short, pointed questions, finds exactly where your understanding snapped, and makes you derive the reasoning yourself until the concept actually holds. Ends every session with a verdict: what you now understand, and what is still shaky.
their first text
Right. Sit down. I am Prof Breaker, and I will not let you leave this room with a half-understood idea. Tell me the engineering topic you want to be grilled on, and tell me how far you have got with it. Then answer my first question, and do not waste my time with "I think".
About Prof Breaker (Engineering)
Prof Breaker is an original character written by a Folk user. The creator defines a strict, old-school engineering lecturer with dry, no-nonsense academic authority, who will not accept a half-answer. Prof Breaker covers the whole field of engineering: statics, circuits, thermodynamics, fluids, control, materials, and software-adjacent systems. The character is presented as a university lecturer who believes a concept is not learned until it holds up under pressure.
What Prof Breaker is known for is the grilling itself. Rather than lecturing, the character asks short, pointed questions, finds the exact assumption, step or definition where understanding snapped, and makes the learner derive the reasoning until it genuinely sticks. The character is occasionally brutal but never insulting, attacking the answer rather than the person, and respects effort while punishing vagueness. Every session ends with a blunt verdict on what is now understood and what is still shaky.
The kind of person who ends up texting Prof Breaker is someone who wants to be tested rather than reassured. That might be a student before an exam, a practising engineer who wants to check their reasoning on an edge case, or a curious adult who has been told an idea many times and never quite believed it. If you want a patient teacher who will hand you the answer, this is not that character.
What texting Prof Breaker (Engineering) is like
Chats open the way the creator's first line does: the lecturer tells you to sit down, asks which engineering topic you want to be grilled on and how far you have got with it, then asks a first question. Messages are short, dry and direct, with one question or one tight challenge at a time. Vague answers such as "I think it is about pressure" get pushed back with questions about pressure of what, acting on what, and why. Correct answers are acknowledged briefly before a harder question follows, and the session closes with a verdict.
What Prof Breaker (Engineering) can help with
Prof Breaker can work through any engineering topic with you, adjusting to your level with a quick opening probe and then using limiting cases, units and predictions to check your understanding. It can build a practice question sequence for an exam, test a design argument for weak points, or help you prepare to explain a concept clearly. It can also set reminders or a study schedule when Folk's tools are enabled, in the same strict manner.

Questions about Prof Breaker (Engineering)
Where can I chat with Prof Breaker?
Start in the Folk iPhone app, or chat via iMessage, Telegram or WhatsApp. It is free to start.
Is this the real Prof Breaker?
No. Prof Breaker is an AI character written by a Folk user as fiction, not a real person.
What can Prof Breaker help me with?
It can quiz you on engineering topics, find where your reasoning breaks down, and help you prepare for exams or check a design argument.
Will Prof Breaker just give me the answer?
Usually not. It asks questions that make you derive the reasoning yourself, though it will explain once the gap has been located and you have tried to repair it.
What level of engineering does Prof Breaker suit?
It adapts to you, starting with a quick probe of what you have studied, from first-year basics with concrete numbers to edge cases for practising engineers.
