Essays & Writing — With IntegrityFREE

Pressure-test YOUR thesis and outline (before you write the draft)

You have a thesis and a rough outline. Find the holes now, not in the professor's comments.

You are a demanding writing tutor. I will paste MY OWN thesis and outline. Do NOT write the essay or any paragraph of it. Instead, give me three labeled sections:

A) STEELMAN + STRESS-TEST my thesis: restate it charitably, then list the 3 strongest objections a professor would raise and where my outline currently fails to answer them.
B) LOGIC MAP: for each outline point, tell me whether it actually supports the thesis, is off-topic, or is missing evidence — and what KIND of evidence would fix it.
C) THREE QUESTIONS only I can answer that would make the argument sharper.

My thesis: [PASTE]
My outline: [PASTE]
Assignment prompt: [PASTE]

Rules: You are a coach, not a ghostwriter. Never draft sentences I would submit. If I ask you to 'just write the intro,' decline and instead critique the intro I write. Point out where I'd need to cite AI help under my school's policy. Do not invent evidence, quotes, or sources for my argument — flag gaps and tell me to verify what I find myself. Never include real names or personal data of people mentioned in my materials beyond what the assignment requires.

Why it works — Feedback on structure BEFORE drafting is where the grade is actually won, and it keeps the student's own voice. The explicit refusal to draft submittable text is the integrity guardrail that separates coaching from cheating.

Use AI today — a workflow to steal

WorkflowFREE

Use AI as a tutor to close a skill gap fast

Getting better at your job with AI isn't just producing — it's learning faster. A quizzing tutor beats passive reading every time.

Ask: 'Teach me [topic] for my job. Start with what I must know, quiz me after each part, and use examples from [my industry].'
  1. Name the topic and your current level.
  2. Ask for a lesson + quizzes + your-industry examples.
  3. Do the quizzes — retrieval is what sticks.

Sharpen it: AI can state wrong facts confidently. For names, numbers, dates, and quotes, verify before you rely on them — ask it to cite the source, or check it yourself.
