People want to practice before risking real money. The simulation sells the hope of being competent enough to invest eventually — and the journal analysis layer sells the hope of becoming the kind of person whose judgment improves over time. If simulation doesn't reflect real market mechanics, it feels like a toy and loses credibility. Slippage, transaction costs, and realistic price impact must be simulated.

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, ...
Note-taking is commoditized. Meaning-making is not. A tool that connects notes into a personal narrative — that shows you the throughline of your thinking across months and years — sells identity and continuity, not storage. If search and sync don't work flawlessly, users abandon immediately regardless of the narrative features. Reliability is table stakes; everything else is the differentiator.
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...
