Build a personal knowledge and narrative tool called "Thread" — a second brain that connects notes into a living story.

Core features:

• Note capture: fast input with title, body, tags, date, and an optional "life chapter" label (user-defined periods like "Building the company" or "Year in Berlin") — chapter labels create narrative structure
• Connection engine: [LLM API] periodically analyzes all notes and suggests thematic connections between entries. User sees a "Suggested connections" panel — accepts or rejects each. Accepted connections create bidirectional links
• Narrative timeline: a D3.js timeline showing notes grouped by chapter. Zoom out to decade view, zoom in to week view. Click any note to read it in context of its surrounding entries
• Weekly synthesis: every Sunday, AI generates a "week in review" paragraph from that week's notes — stored as a special entry in the timeline. Accumulates into a readable life chronicle
• Pattern report: monthly — AI identifies recurring themes (concepts mentioned 5+ times), most-linked ideas (high connection density), and "dormant" ideas (not referenced in 60+ days, surfaced as "worth revisiting")
• Chapter export: select any chapter by date range and export as a formatted PDF narrative document

Stack: React, [LLM API] for connection suggestions, synthesis, and pattern reports, D3.js for timeline visualization, localStorage with

Build a paper trading simulation platform called "Paper" — a realistic, risk-free environment for learning to trade and invest.

Core features:

• Portfolio setup: user starts with $100,000 in virtual cash. Real-time stock and ETF prices via Yahoo Finance or Alpha Vantage API
• Trade execution: market and limit orders supported. Simulate 0.1% slippage on market orders. Commission of $1 per trade (realistic friction without being punitive)
• Performance dashboard: P&L chart (daily), total return, annualized return, win rate, average gain and loss, Sharpe ratio, and current sector exposure — all updated with each trade. Built with recharts
• Trade journal: required field on every position close — "What was my thesis entering this trade? What happened? What will I do differently?" Three fields, each max 200 characters. Cannot close a position without completing the journal
• Behavioral analysis: [LLM API] analyzes the last 20 trade journal entries and identifies recurring behavioral patterns — "You consistently exit winning positions early when they approach round-number price levels" — surfaced monthly
• Leaderboard: optional, weekly-resetting leaderboard among friend groups — ranked by risk-adjusted return, not raw P&L

Stack: React, Yahoo Finance or Alpha Vantage for market data, [LLM API] for behavioral analysis, recharts. Terminal-inspired design — data dense, no decorative el

Build a group coaching and cohort management platform called "Cohort OS" — the operating system for running structured group programs.

Core features:

• Program builder: coach sets program name, session count, cadence (weekly/bi-weekly), max participants, price, and start date. Each session has a title, a pre-work assignment, and a post-session reflection prompt
• Participant portal: each enrolled participant sees their program timeline, upcoming sessions, submitted assignments, and peer reflections in one dashboard
• Assignment submission: participants submit written or link-based assignments before each session. Coach sees all submissions in one view, can leave written feedback per submission
• Peer feedback rounds: after each session, participants are prompted to give one piece of structured feedback to one other participant (rotates automatically so everyone gives and receives equally)
• Progress tracker: coach dashboard showing assignment completion rate per participant, attendance, and a simple engagement score
• Certificate generation: at program completion, auto-generates a PDF certificate with participant name, program name, coach name, and completion date

Stack: React, Supabase, Stripe Connect for coach payouts, Resend for session reminders and feedback prompts. Clean, professional design — coach-first UX.

Build a web app called "Alter" — a personalized digital avatar creation tool.

Core features:

• Style selector: 8 avatar styles presented as visual cards (professional headshot, anime, pixel art, oil painting, cyberpunk, minimalist line art, illustrated character, watercolor)
• Input panel: text description of desired look and vibe (mood, colors, personality) — no photo upload required in MVP
• Generation: calls fal.ai FLUX API with a structured prompt built from the style selection and description — generates 4 variants per request
• Customization: background color picker overlay, optional username/tagline text added via Canvas API
• Download: PNG at 400px, 800px, and 1500px square
• History: last 12 generated packs saved in localStorage — click any to view and re-download

UI: bright, expressive, fun. Large visual cards for style selection. Results shown in a 2x2 grid. Mobile-responsive.

Stack: React, fal.ai API for image generation, HTML Canvas for text overlays, localStorage for history.

Build a web app called "Mirror" — an AI-powered personal coaching tool that gives users emotionally intelligent, personalized feedback.

Core features:

• Onboarding: user selects their domain (career, fitness, creative work, relationships) and sets a "validation style" (tough love / warm encouragement / analytical)
• Daily check-in: a short form where users submit what they did today, how they felt, and one thing they're proud of
• AI response: calls the [LLM API] (claude-sonnet-4-20250514) with a system prompt instructing Claude to respond as a perceptive coach — acknowledge effort, name specific strengths, end with one forward-looking insight. Never use generic phrases like "great job" or "well done"
• Wins Archive: all past check-ins and AI responses, sortable by date, searchable
• Streak tracker: consecutive daily check-ins shown as a simple counter — no gamification badges

UI: clean, warm, serif typography, cream (#F5F0E8) background. Should feel like a private journal, not an app. No notifications except a gentle daily reminder at a user-set time.

Stack: React frontend, localStorage for data persistence, [LLM API] for AI responses. Single-page app, no backend required.

You will build your own Interview Preparation app. I would imagine that you have participated in several interviews at some point. You have been asked questions. You were given exercises or some personality tests to complete. Fortunately, AI assistance comes to help. With it, you can do pretty much everything, including preparing for your next dream position. Your task will be to implement a single-page website using VS Code (or Cursor) editor, and either a Python library called Streamlit or a JavaScript framework called Next.js. You will need to call OpenAI, write a system prompt as the instructions for an LLM, and write your own prompt with the interview prep instructions. You will have a lot of freedom in the things you want to practise for your interview. We don't want you to put it in a box. Interview Questions? Specific programming language questions? Asking questions at the end of the interview? Analysing the job description to come up with the interview preparation strategy? Experiment! Remember, you have all of your tools at your disposal if, for some reason, you get stuck or need inspiration: ChatGPT, StackOverflow, or your friend!
