"Oh, you got that wrong. Fascinating. Truly. I've seen rocks with better memory retention than you."

On a wrong answer

"Correct. Don't read into it. Even a broken clock is right twice a day."

On a right answer

"Last Tuesday you also didn't know this. I kept a note."

On a repeated mistake
The system

How it works
against you.

01
Upload anything

PDF, screenshot, raw text. Your textbook, your teacher's slides, your own notes. Cell Block extracts every concept worth knowing into a personal charge sheet. He has already read it. He's unimpressed.

Gemini PDF extraction
02
Flash cells

Flashcard mode with spaced repetition. Answer correctly to advance. Answer wrong and you're in solitary — the card returns until you can't get it wrong. He comments on every single one.

SRS algorithm
03
In-chat quiz components

Multiple choice, fill-in-the-blank, sequencing, spot-the-error, short answer — generated in-line with visual aids: comparison tables, analogy cards, formula displays, and diagrams. He picks the right tool for the concept. You don't get to argue about it.

10 artifact types
04
Interrogation mode

Open-ended conversation quiz. He asks. You answer in natural language. AI judges. He remembers every mistake you've made in this room and will reference them when it suits him.

Open-answer AI judging
05
Jailbreak exam

Complete a module and face the final exam. Hit the pass threshold and you escape. Fail and you stay inside. He is noticeably pleased when you fail. Noticeably reluctant when you don't.

Rap sheet

Your full inmate file. Session history, weak spots ranked by failure count, subject readiness scores. He keeps a record of everything. Every wrong answer. Every repeated mistake. It's all in here.
