This 2 hour Stanford lecture shows exactly how Stanford trains it's engineers to build AI systems. It's more practical than every Claude tutorial & prompting threads you've seen.
Bookmark & give it 2 hours, no matter what. It'll be the most productive thing you do this weekend.
🚨 Tutors charge $50/hour. Coursera charges $50/month. Someone built an AI that uploads your textbooks and becomes a personal tutor that never sleeps. 10,300 GitHub stars. Free.
It's called DeepTutor.
An AI-powered learning assistant that reads your textbooks, research papers, and documents. Then teaches you from them. Personally.
Not a chatbot. Not a search engine. A full multi-agent tutoring system that solves problems step by step, generates practice exams, creates visual explanations, and conducts deep research. All from YOUR materials.
Here's what this system does:
→ Upload textbooks, papers, technical docs. It builds a knowledge base from YOUR content.
→ Ask any question. AI answers with step-by-step solutions and citations from your materials.
→ Generates quizzes and practice problems matched to your level
→ Upload a real exam. It creates practice questions that mimic the exact style and difficulty.
→ Deep Research mode: decomposes topics, dispatches parallel agents, produces cited reports
→ Guided Learning: turns your materials into visual, interactive learning paths
→ AI Co-Writer: markdown editor where AI helps you write, rewrite, and expand
→ Personal TutorBots: autonomous tutors with their own memory, personality, and workspace
Here's the wildest part:
TutorBots are not chatbots. They're autonomous agents with soul files that define their personality. Create a Socratic math tutor. A patient writing coach. A rigorous research advisor. All running simultaneously. Each with its own memory. Each evolving as you learn.
They even have a heartbeat system. Your tutor shows up with study reminders and review check-ins. Even when you don't ask.
An AI tutor that initiates. That remembers. That adapts. That never bills you.
Private tutors: $50 to $100/hour. Coursera: $50/month. Chegg: $15/month. University tuition: $20,000+ per year.
This is free. Self-hosted. Your data stays on your machine.

This video melts my heart! 🥹 A calf bringing food to its tied mother is the sweetest thing I've seen all day. What an incredible display of love! ❤️ So much to learn from these gentle creatures. 🥺
Rahul Gandhi’s tweet on the Uttam Nagar tragedy is peak hypocrisy and selective outrage.
While a 26-year-old Dalit youth, Tarun Khatik, was brutally beaten to death with rods, stones and slabs over a Holi water balloon mishap—Rahul equates the victim’s family with the accused Muslim murderers’ family, calling the latter “persecuted” and victims of “harassment.”
Tarun lost his life. But Dalit life matters only if it fits the narrative. Not when the accused is from a Votebank!
Justice for Tarun not twisted sympathy & whitewashing for killers.
Real mohabbat starts with truth not vote-bank gymnastics.
Agree: scaling AI in healthcare requires meticulous planning & governance, not just pilots. AHN is actively building the infrastructure and discipline to ensure our AI deployments are sustainable, ethical and truly transform care. https://t.co/88qot6rrK7

@AHNtoday - please correct the map of India. The green color regions are integral part of India. Hope this was not intentional. Need to look into who made this flyer for you. Hope you remove this from circulation and issue correction.
Please be transparent with your policies for business class customers lounge access. You take money on https://t.co/pCch1k0PWB but when need help , you deny or ask to contact your partner airline.

Fly in style but don't expect good customer service from United at their Lounges. They expect you to read their contract with before booking flight. No transparency! @united
Just came back from an international trip on a business class ticket- their normal wifi was not working. Paid $12k for tickets - did not know $8 wifi was and Lounge access in Chicago not included for business class when returning to US and waiting for connection. Pathetic !
