6 Private AI Tools

For The Things You'd Never
Type Into ChatGPT.

📄
Resume Coach

Upload your PDF or DOCX resume alongside a job description. The AI scans for keyword matches, flags what's missing, and rewrites weak bullet points — giving you specific before/after examples, not vague advice.

"Analyze resume for Python role at Stripe" → keyword gaps + 3 bullet rewrites

🏥
Health Decoder

Paste your diagnosis, prescription name, or lab values. Get a plain-English breakdown of what each term means and a list of specific questions to bring to your next appointment. No medical jargon left unexplained.

"Hypertension stage 2, prescribed lisinopril 10mg" → explanation + 3 doctor questions

💰
Money Translator

Paste a clause from your loan agreement, insurance policy, or tax document. The AI translates it into plain English and highlights the parts you should watch out for — hidden fees, penalty clauses, unfavorable terms.

"What does this prepayment penalty clause mean?" → plain explanation + red flags

✍️
Ghost Writer

Describe the message you need to write — resignation letter, difficult apology, boundary-setting text, landlord complaint. Get a complete draft that matches the tone and situation, not a generic template with [YOUR NAME] placeholders.

"Resign after 2 years, good terms, want to keep relationship" → full letter draft

📓
Private Journal

Write about a tough decision, a complicated feeling, or a situation you can't discuss with anyone. The AI reflects your words back thoughtfully, reframes your perspective, and asks one question to sit with — without ever storing or judging.

"I'm overwhelmed about a career change at 35" → reflection + reframe + one question

🔬
Explain It

Ask about any topic — compound interest, quantum physics, how immigration law works, what an LLC actually is. Get a structured explanation with key points and a summary. Learn clearly, privately, and at your own pace.

"How does compound interest work?" → explanation + 4 key points + summary
